Background

Background on page 1 ACP subsystem interdependences on page 3 Major ACP features on page 4

The two-way Hughes product requires a polarized transmitter at the user location. The antenna associated with the transmitter must be properly aligned to maximize the signal on the correct transponder (called the co-pol) while minimizing the signal on the adjacent transponders (called the cross-pol). An earth station may leak energy to the opposite (horizontal or vertical) polarization when transmitting on the desired polarization. This may be caused by problems with antenna cross-pol isolation or installation/antenna pointing. If a remote terminal leaks enough energy to the opposite polarization, it can interfere with traffic at the same frequency on the opposite transponder. The satellite vendor may request satellite users to check their transmission on the cross-pol to prevent this type of interference. The ACP Server supports the communication and measurement functions needed to ensure the remote antennas are properly aligned as required to initiate two-way service, and periodically verify they remain optimally aligned. The ACP Server provides the measurement for the client's cross-polarization requests. It operates up-to 224 rack-mounted spectrum analyzers, connected by General Purpose Interface Bus (GPIB) cables. Each GPIB supports up to 14 spectrum analyzers (seven pairs). The ACP Server: • • •

The client's cross-polarization requests consist of three parts: •

Pointing—used by the installer to make fine adjustments while pointing the antenna. It allows an installer to get continuous feedback for up to a configured period of time

(once per second for up to 5 minutes as configured on the National NOC). Validate—used to enable a remote that is disabled due to pointing tests (TX21, TX22, and TX23) issued to confirm the accuracy of the antenna cross-pol alignment. The remote transmitter is enabled after the unit passes the validate tests. Revalidate—used to periodically check the remote antenna's cross-pol alignment.

A simplified example of this process flow is shown in Figure 1 and the basic procedure is described briefly below:

1. The antenna is pointed . This consists of peaking the receive signal strength by adjusting the antenna’s azimuth and elevation, while keeping the polarization setting at the value calculated by the Web Setup program. This is performed using feedback from the IRU. 2. Antenna polarization is adjusted by the installer using the Cross-pol Pointing mode of operation: a. The remote requests Cross-pol Pointing using unallocated ranging bursts. b. The ACP Server responds with information about the installer's/remote's place in the queue. c. In turn, the remote is provided with a test frequency. Testing consists of the remote sending a narrow-band continuous wave (CW) carrier signal. d. The ACP Server measures the cross-pol and co-pol values using a pair of spectrum analyzers. The ACP Server

2


provides periodic feedback to the remote based on the cross-pol isolation measurement. e. Based on this feedback, the installer peaks the remote antenna's polarization. If the desired degree of isolation cannot be achieved, the installer may make additional minor azimuth and elevation adjustments at the remote antenna. If these adjustments fail to achieve the desired isolation level, Operations or Customer Care Center personnel may be consulted for additional support. 3. Once the antenna has been locked down, a Cross-pol Validation test confirms the cross-pol isolation has been achieved. The remote must pass this test before it will be enabled for normal transmit operation. 4. Periodically, the remote automatically revalidates itself to confirm that its cross-pol isolation still meets the specified requirement. The Revalidation requirement is less stringent than the Validation requirement, to avoid disabling remotes based on normal expected variances.

ACP subsystem interdependences

The ACP Server works with the DNCC, Timing Unit, and Satellite Gateway in the NOC. Figure 2 is a simple depiction of the packet flow. The ACP Server operation is based on network timing. The ACP Server uses Superframe Numbering Protocol (SFNP) messages sent by the Timing Unit to obtain frame numbers. The arrival of these SFNP messages, approximately every 360 ms, serves as the ACP Server’s clock for scheduling Pointing, Validation, and Revalidation events. The ACP Server receives SFNP messages from the Timing Unit as they are being transmitted to the remotes and to the Local/Echo Timing IRUs. A separate DW6000 remote (required to support Extended Ku-Band frequencies) connected to the ACP Server is designated the Calibration Remote. This DW6000 is used to calibrate all the


3

spectrum analyzer groups connected to the ACP via the GPIB serial bus.

Figure 2: ACP subsystem relationship

All DNCCs in the network must recognize the correct IP address and port configured for the ACP Server to allow them to communicate with it over the MUX LAN. Requests for ACP measurements are received by the ACP Server via UDP-based multicast messages from the DNCCs as shown in the figure. SFNP information sent from the Timing Unit allows the ACP Server to enable the ACP process. The Timing Unit relays network timing information to the ACP Server. The ACP Server’s responses are sent out to the remotes via the Satellite Gateway.

Major ACP features Regional ACP The user’s dish antenna must be pointed during the initial installation to the proper azimuth, elevation, and polarization. The user’s remote antenna transmits over a dual-polarity satellite. Therefore, the antenna polarization must b e finely tuned to ensure that the transmitted signal does not bleed onto the adjacent transponder, which shares the same frequency space. A CW is transmitted from the remote site to help an installer fine-tune the polarization. This signal is measured at the NOC on both horizontal and vertical polarizations. These measurements are processed and provided to the installer as a strength level or signal quality factor (SQF) that indicates the isolation. The satellite does not provide the same gain for all locations in the country, therefore many installations cannot pass the automated cross-pol testing. These are areas in the satellite

4


footprint where the co-pol cannot achieve a strong enough signal to provide the required isolation from the cross-pol noise floor. To account for the satellite variations, the necessary isolation level must be determined using the location of the antenna, which has already been entered during the installation process. The IRU will supply the location of the antenna, in terms of latitude and longitude, as part of the ACP request. On the PC client, this location is based on the Zip code lookup table provided as part of the PC client. When the ACP Server receives a LatLong value in the ACP request, will determine the first zone in its tables that match the site. The zone will be determined as a polygon, based on the latitude and longitude coordinates of the apexes relative to a signal strength contour map.The Regional ACP Server feature allows you to specify a threshold based upon the dish antenna location. A regional configuration file defines the regions and


5

their Pointing, Validate, and Revalidate thresholds. Figure 3 shows an example of this type of configuration file.

T01470003

Figure 3: Regional ACP configuration file format

This configuration file is located in the ACP root registry entry called PolyConfFile. Use Windows WordPad or another text

6


editor to modify the file parameters as necessary. The file must be formatted exactly as shown in Figure 3. Note:

Parameters shown in the example are not actual values.

The region configuration file may contain several regions. Each region has a region name. The next line specifies the unique ID for the region, which is used in the ACP result log file to identify the region in which the dish resides when the cross-pol measurement is performed. The third, fourth, and fifth lines define the thresholds (in 0.1 dB units) for pointing, validation and revalidation. The next (three, four, five, or more) lines designate the latitude and longitude of each apex of the area polygon. The # symbol terminates the region definition. The registry parameter for this feature is located at

HKEY_LOCAL_MACHINE|SOFTWARE|Hughes Network Systems\DirecPC\ACP The DisableRegionalACP value is set to 1 (disabled) by default. The value must be changed to 0 to enable Regional ACP. A command utility program, RegionCheck , is provided to test the validity of the region configuration file. To use RegionCheck, open a command prompt window and type RegionCheck where filename is the region configuration filename. This utility displays any errors it detects.

Frequency auto-centering The frequency and span of the co-pol/cross-pol frequencies are statically configured on the ACP Server with the assumption that the carrier frequency is stable over time. However, the ACP test carrier frequency can drift from a few hundred hertz to a few thousand hertz. If the carrier drifts outside the measurement scope of the spectrum analyzers, the ACP Server only measures noise, rather than the transmission signal, missing the actual peak of the measurement carrier. When enabled, the Frequency Auto-centering feature will automatically center the carrier frequency, thus preventing the signal from drifting out of the spectrum analyzer’s configured range (or span) and invalidating the measurements. The ACP Server recalibrates all the spectrum analyzer pairs at a pre-configured interval. The calibration unit is a remote that is usually co-located with the server and has a 45-degree polarization misaligned dish. The calibration unit transmits a CW wave with equal signal strength on both the co- and crosspolarizations. This mechanism can be used to automatically center the carrier frequency, under two possible scenarios:

•

•

When the frequency drifts a relatively small amount and the signal is still within the scope of the spectrum analyzer. The ACP Server measures the strength and frequency of the CW signal transmitted by the calibration unit. If the delta between the signal frequency and the center of the scope is greater than what was configured, the ACP Server automatically adjusts the spectrum analyzer settings to move the CW back into the center of the scope. The ACP Server limits the frequency shift within the maximum allowed limit. If the adjustment value exceeds the maximum allowed frequency adjustment limit, a SNMP alarm is sent and the pair is disabled. When the frequency drifts out of the scope of the spectrum analyzer, the ACP Server can only measure background noi se to determine there is no signal. If no signal is detected, the ACP Server doubles the span of the spectrum analyzers and searches for the signal. When the signal is located, the server adjusts the measurement frequency back to the center of the scope then restores the original span. If a signal still cannot be detected after the span is expanded, the server sends out an SNMP alarm and disables the pair. It is important to compare the frequency of the signal with the adjacent ACP frequency value to ensure the correct signal is located.

The ACP Server actively monitors the ACP measurements such as Pointing, Validate and Revalidate. The remote's tuner is very accurate and transmits at the frequencies allocated by the ACP Server. The ACP Server can check the co-pol signal position for each cross-pol measurement. If the co-pol peak is de tected around the edge of the spectrum analyzer for N consecutive times (Two registry key values are used: the allowed frequency delta value from the center frequency and counter N ), ACP Server can initiate the calibration process to center the frequency based on the procedure described above regardless of the calibration interval setting.

Extended Ku-band frequency The ACP Server supports extended Ku-band frequencies support (13.75 GHz to 14.5 GHz).

ACP Server subsystem ACP Server redundancy is not supported in the current capacity and limitations implementation. Each ACP Server can support up to 32 GPIB

controllers. Each GPIB controller can support up to seven pairs of spectrum analyzer pairs (14 total), for a total of 224 spectrum analyzer pairs.

Chapter 3

ACP rack installation The ACP equipment can be installed in its own rack or in a shared rack. The rack can be off the shelf or provided by Hughes. This chapter addresses an Hughes-provided rack for exclusive ACP use. This chapter describes the procedures for installing the ACP rack in both earthquake-prone and non-earthquake-prone areas. These topics are explained in detail: • • • • • • •

Overview

Inspecting rack equipment on page 17 Tools and materials required for installation on page 18 Unpacking the rack on page 18 Preparing the raised floor for rack mounting on page 20 Installing bushings and bushing plugs on page 39 Power and ground connections on page 40 Rear rack door installation on page 42

The ACP rack should be installed on a sturdy, horizontal surface which is elevated above the building floor in order to run incoming and outgoing wires and cables to the rack. The wiring and cable route must be accessible via the openings built into the top and bottom of the rack for this purpose. The rack itself is anchored to the floor structure by earthquake-protective screws and fasteners.

The ACP rack must be installed in restricted access areas (for example, dedicated equipment rooms or equipment closets) in accordance with Articles 110-16, 110-17, and 110-18 of the National Electric Code, ANSI/NFPA 70.

Inspecting rack equipment

Inspect all shipping crates, boxes, or other containers for external damage; any damage should be noted before opening. Report any equipment damage to the shipping carrier immediately for claim purposes. Save all the packing material until the rack installation has been completed. Use the BOM as a checklist to inventory the shipment contents and to verify that all items noted in it are

Preparing the raised floor for rack mounting

Follow this procedure to prepare the raised floor for the mounting of the ACP rack. 1. Measure the floor panels—panel measurement may be stated in U.S. Standard or metric. – U.S. Standard: 24 inches wide. – Metric: 600mm wide. 2. Determine appropriate alignment for rack mounting (front or rear): – For rear- aligned racks on standard panels, see Figure 8 on page 21. – For rear- aligned racks on metric panels, see Figure 9 on page 22. – For front- aligned racks on standard panels, see Figure 10 on page 23. – For front- aligned racks on metric panels, see Figure 11 on page 24. 3. After referencing the correct figure, use a pen to mark the floor panels to indicate where the rack will be placed. 4. Using the marks as a reference, use a ¾-inch drill bit to drill each hole through the floor panel. Note: Floor panels may be pre-cut based on the dimensions given in the floor layout diagrams. Be sure to use the correct floor layout diagram for the site.

5. Use a reciprocating saw to remove rectangular cut-outs. Note: If floor panels contain concrete, it may be necessary to use a diamond saw to remove cut-outs.

6. If installing the ACP rack in a non-earthquake area, follow the procedures in Mounting the rack on a raised floor (non-earthquake) on page 25. 7. If installing the ACP rack in an earthquake area, follow the procedures in Mounting the rack on a raised floor (earthquake) on page 30.

4. Insert cables through the bushing holes where needed and connect to the appropriate locations.

Power and ground connections

The AC input line from the main AC power source is connected by a 3-wire 8-AWG cable according to the site specific color code. The Puluzzi PDU and main AC power source is connected through the female/male L6-30, 240 V 30A twist lock. Each 30 A feed is connected to the 30A building power breaker. The twist lock is considered the quick power disconnect point.

The main power connection twist lock is a safety quick disconnect device in addition to the PDU power switches. Use this switch to disconnect main power before performing any work inside the ACP rack. The high leakage current can be potentially hazardous and could result in death or serious injury.

40


For sites requiring UL approval, a readily accessible UL–listed circuit breaker rated 30A per feed maximum must be provided adjacent to the rack to serve as the disconnect device and overcurrent protection device. Failure to comply with this warning could result in personal injury caused by electric shock.

Verify that the UL-listed circuit breaker is off before routing a power cable from the circuit breaker to the ACP rack. To prevent accidental activation of the circuit breaker while installation work is in progress, tag and/or lock the circuit breaker to indicate that the equipment is being serviced. Failure to comply with this warning could result in personal injury caused by electric shock.

For CE-compliant sites, a readily accessible CE-compliant device must be provided adjacent to the rack to serve as the disconnect device and overcurrent protection device. Failure to comply with this warning could result in personal injury caused by electric shock.

Verify that the CE-compliant device is off before routing a power cable from the device to the ACP rack. To prevent accidental activation of the CE-compliant device while installation work is in progress, tag and/or lock the device to indicate that the equipment is being serviced. Failure to comply with this warning could result in personal injury caused by electric shock.

Ground connection

1. Verify that the UL-listed circuit breaker or CE-compliant device is off. 2. To prevent accidental activation of the UL-listed circuit breaker or CE-compliant device while work is in progress, tag and/or lock the UL-listed or CE-compliant device to indicate the equipment is being serviced. This is to prevent physical injury as described in the warnings above. 3. Route the power and earth ground cables from the UL-listed circuit breaker (for UL-compliant sites), or the CE-compliant device (for CE-compliant sites) to the ACP rack.


41

High leakage current present—earth connection is essential before connecting AC supply.

Rear rack door installation

If the rear rack door is already installed, then this section is complete. Otherwise, install the door by aligning its hinges with the rack’s hinge pins, then lower the rear door onto them. Verify that all door hinges are seated on their hinge pins and that the door opens and closes properly.

The rear rack doors are a part of the fire enclosure. therefore, to avoid a fire hazard, they must be closed when the equipment is not being serviced. Failure to comply with this warning could result in personal injury and equipment damage caused by fire.

Grounding The ACP rack is grounded for safety with a green/yellow tracer 10AWG wire. All modules where AC power is delivered will be grounded via wires attached to a point on the rack’s unpainted surface. For signal ground, an extra ground wire is attached between the rack and any other peripheral devices.

Chapter 5

Setting up the ACP The procedures in this chapter are intended for initial ACP installation and for recalibrating the system. Recalibration is typically required in cases where you experience significant level, transponder, or load changes. Recalibration may also be required in situations when the frequency drifts outside the spectrum analyzer measurement span range if you are not using the frequency auto-centering feature. This chapter is covers the following topics: • • • • •

•

Initial ACP set up

Initial ACP set up on page 93 NOC requirements on page 94 Optimizing calibration remote antenna pointing on page 96 Measuring calibration values on page 99 Calculating ACP_SYS_CopolOffset and ACP_SYS_XOffset on page 100 Modify ACP Server registries on page 102

Use this procedure to set up the system to perform automatic ACP. The first step is to select a pair of transponders and generate a link budget. 1. From the ACP Server, select a transponder for co-polarization (co-pol) and a transponder for cross-polarization (cross-pol). Use the same frequency for both, ensuring bandwidth is available on both transponders. Typical carrier spacing used is 25 kHz between ACP frequency pairs. Note: The number of pairs/frequencies are based on network throughput requirements.

2. Generate a link budget using the worst-case Transmit source (DW remote, smallest antenna, lowest power contour) into the ACP Receive Antenna. Develop the link budget using a CW signal (pointing losses/TX power from a typical link

Chapter 5 • Setting up the ACP 1032039-0001 Revision C

93

budget) measured in a 30 Hz (maximum) resolution bandwidth. The result at the ACP Receive Antenna should be at least 40 dB c/n (carrier-to-noise) to permit you to make a cross-pol measurement of up to 35 dB relative to the carrier. 3. Repeat this procedure for both transponders.

NOC requirements

The NOC must meet these requirements to reliably perform ACP measurements: •

• • •

The outroute spacelink must be healthy enough for the remote to accurately receive commands from the NOC in a timely manner. Send Test commands can be successfully sent to remotes. The calibration remote can generate CW tones. ACP Server software has been loaded and the server is operating properly.

You will need a DW6000 ACP Transmit calibration remote. The calibration unit is a separate unit (typically a DW6000). A DW6000 must be used as the calibration remote in an extended Ku-band network, in systems with outroutes narrower than 5 Msps, and in systems supporting turbo-coded inroutes only.


94

T01470006

Figure 96: ACP System test configuration diagram

L-band frequency inputs for each transpon der are required to feed the ACP Spectrum Analyzer rack. This input can be from any antenna that meets link budget requirements. The L-band frequencies must be very stable (<1 kHz drift over 24 hours), preferably locked to the system reference clock. The levels presented to the ACP rack input must be at least -70 dBm.


95

Optimizing calibration remote antenna pointing

This section describes how to optimize the calibration antenna performance. The major tasks are: • •

•

Selecting the ACP Receive Antenna system. Determining the operating points of each transponder using the link budgets and information from the satellite vendor. Using the test site calibration antenna, measure each transponder and reconcile the link budget.

Use this procedure: 1. Connect the calibration antenna system to the DW6000 remote if you have not already done so. See Figure 96 on page 95. 2. Under the DNCC GUI General tab, select the EnableITU command. 3. Enter the DW6000 Satellite Interface Serial Number you recorded in step 7 on page 89.


96

4. Set the Enableflag value to 1 as shown in the figure below, then click the Send button.

Figure 97: DNCC available - Endableflag screen

5. Select SendTest from the IRU Command menu. 6. Enter the DW6000 serial number again. 7. Enter 8 as the Pattern value. Check the Repeat every 30s box and click Send to start transmitting the CW signal.


97

8. Type in the center frequency (ACP registry CenterFrq value) in 100 Hz units as shown.

Figure 98: DNCC available - CenterFrq screen

9. On the Co-pol transponder, peak the antenna on the transmit carrier. It should have the polarization set, cross-pol nulled. This can either be done at the NOC hub antenna (LNA coupled ports), or with the satellite vendor. 10. Once the antenna pointing is complete, record the polarization setting. Measure and record the downlink power and the absolute frequency of the transponder: Polarization setting ______________ Downlink power ________________ Frequency _____________________ 11. On the Cross-pol transponder, peak the antenna on the transmit carrier. It should have the polarization set, co-pol nulled. This can either be done at the NOC hub antenna (LNA coupled ports), or with the satellite vendor.


98

12. Once the antenna pointing is complete, record the polarization setting. Measure and record the downlink power and the absolute frequency of the transponder: Polarization setting ______________ Downlink power ________________ Frequency _____________________ 13. Verify the levels recorded in Step 10 and Step 12 are within 1 dB of each other. If the levels are not within 1 dB, re-peak the side with the lower measurement and record the updated values. Note: Level differences can be caused by different satellite transponder gain settings. If you are unable to get the values within 1 dB, consult your satellite vendor to confirm your transponder gain settings. The difference in downlink power will be used to calibrate the system later. It is also used to determine the relationship between remote measured deltas between polarizations and actual cross-pol isolation.

14. Rotate the polarization back towards the co-pol until the downlink power on the cross-pol side is 50% of the original measured value. Verify that the co-pol measured value is also 50% of its original measured value.

Measuring calibration values

The measured values are used to determine the proper registry entries for these parameters: • • • • • •

CopolNoiseFloor XpolNoiseFloor Noiseceiling ITUTransmitLimit ACP_SYS_CopolOffset ACP_SYS_XOffset

These registry values must be changed based on the actua l system measurements. The values you will need to enter into the registry are derived from these measured values. 1. Verify the CW signal is still being transmitted. 2. Set the co-pol spectrum analyzer Span to 2 kHz and center the CW on the screen. Adjust your Reference Level and dB/Div so that the peak of the CW is one graticule below the top of the screen and you can see below the noise floor. Set trace B to Max Hold so you can measure the maximum noise floor level.


99

3. Measure the carrier peak level using the Peak search function. Record this frequency in the Measured co-pol CW (in MHz) row in Table 23 on page 109. Note: Record this number in 1 Hz resolution. Subtract 10 dB from the measured carrier level and enter the result into the ITUTransmitLimit co-pol column in Table 4 below.

4. Position the spectrum analyzer Display Line near the trace B maximum level. Add 5 dB to that level and record the sum into the Noiseceiling co-pol column. Record the Reference Level setting in the CopolNoiseFloor/XpolNoiseFloor co-pol column. 5. Repeat steps 1, 3, and 4 for the cross-pol spectrum analyzer. 6. Turn off the CW tone from the DNCC GUI. From the SendTest menu, highlight the active serial number(s), and click the Stop button. Table 20: Measured ACP calibration levels Measurement from spectrum analyzers

IRU Control tab commands Following are procedures for initiating IRU control tab commands:

Validate:

Enter the IRU serial number into the Serial Number field. Select Validate from drop-down list. Click Send to initiate validation for the specified serial number.

Revalidate:

Enter the IRU serial number into the Serial Number field. Select Revalidate from drop-down list. Click Send to initiate Revalidation for the specified serial number.

ForceEnable:

This command is used to enable a remote's transmitter based upon the serial number entered in the Serial Number field.

ForceDisable: This command is used to disable a remote's transmitter based upon the serial number entered in the Serial Number field.

Figure 103: URU Control tab screen

Redundancy tab commands Use the Redundancy tab to enable or disable local and remote ACP Servers and monitor their operation. The LocalACP command button indicates ACP operating status. The button is disabled and an ACP Unreachable message appears if the local ACP Server is not running when it starts. Otherwise, the button is enabled and displays Go Offline or Go Online .


105

Using the Configure tab When a configuration value is modified, the ACPGUI instructs the ACP Server to dynamically update the parameter and waits for an acknowledgement. If the ACP Server does not acknowledge the update, the value remains unchanged. The ACPGUI Configure tab cannot be used to make static changes when the ACP service is not operating. Any changes must be modified through the registry directly.

IP address configuration The ACPGUI program uses dialog boxes to modify configuration values. This is the most commonly used dialog box. It displays a variable name and an edit box to enter a new IP value as shown in Figure 104.

Figure 104: IP address configuration window

Configuring ACP Server for manual cross-pol

Manual cross-pol can be used to verify that the remote has correct timing configured (works without receiving packets from the remote). The ACP Server is configured to run in simulation mode, which allows you to use the ACP Server to send out ACP commands without any hardware requirement. Use this procedure to enable the ACP Server to run in simulation mode.

1. Set the registry key to 1. HKEY_LOCAL_MACHINE\SOFTWARE\Hughes Network Systems\DirecPC\ACP\simulation

106


2. Disable all the spectrum analyzers pairs in the registry.

Figure 105: ACPGUI_Local screen

3. Configure the HKEY_LOCAL_MACHINE\SOFTWARE\Hughes Network Systems\DirecPC\ACP\ACP_SYS_ACPMgmtIP

to be the IP address of the interface which intends to receive the network messages from the remote ACPGUI. (If IP address is configured as 127.0.0.1, only ACPGUI running in the local machine can connect to the ACP Server. If a remote ACPGUI is intended to connect to the ACP Server, the REAL IP address must be configured.) 4. Start the ACP Server. The ACP Server will be able to serve the remote GUI clients.

Performing a manual cross-pol check

Use this procedure to check the cross-pol for a remote unit. 1. 2. 3. 4. 5. 6. 7.

From the DNCC, enable remote to transmit a CW signal. Use the spectrum analyzer to monitor the signal at the NOC. Adjust the ODU/antenna to obtain the highest level possible. Record this angle as the initial reference point. Turn the ODU left to obtain the lowest level possible. Record this angle. Turn the ODU right, past the highest point marked in step 4, to again obtain the lowest possible level. 8. Record this angle.


107

The final position can be calculated in the middle of the lowest point. It should be very close to the initial point.

ACP result logging

ACP result logging on page 109 ACP console output message on page 112 System monitoring on page 115

The ACP uses record files to report the status of pointing, validation text and revalidation attempts. An ACP record file is a plain text file with a name similar to acp2.19.2004_13-16-55.log. The name indicates the file creation time. In this example, the file was created on Feb. 19, 2004, at 1:16:55 p.m. Files can be empty or may contain multiple pointing records. Each ACP record appears as one line in the file. The record file parameters are described in Table 23.

Chapter 8

Using a remote GUI This chapter provides information on configuring and using a remote ACPGUI.

Remote ACPGUI

The following parameter types are used when configuring an ACPGUI client: • •

ACP management configuration parameters RemoteGUI key

Management parameters ACP management configuration parameters are located at: [HKEY_LOCAL_MACHINE\SOFTWARE\Hughes Network Systems\DirecPC\ACP] They are: •

•

ACP_SYS_ACPMgmtTCPPort = dword:PORT_NUMBER The ACP listens on this port. ACP_SYS_ACPMgmtIP=IP_ADDRESS The ACP listens on this IP address.

Operation At startup, the ACP launches a TCP server that will handle connection requests from up to eight ACPGUI clients. This number can be easily extended to support more simultaneous connection.

RemoteGUI key parameters A new key GUI is added to define the available ACP Server's IP addresses and port numbers. The ACPGUI can connect to the ACP Server running on a different computer. The key is located at:

[HKEY_LOCAL_MACHINE\SOFTWARE\Hughes Network Systems\DirecPC\ACP\GUI] They are: • • • • •

ACPServerPort1 ... ACPServerPort8=dword:PORT_NUMBER(1...8) ACPServerIP1... ACPServerIP8=IP_ADDRESS(1...8) ACPServerName1... ACPServerName8=ACP_NAME(1...8) A maximum of 8 targeted ACP Servers can be configured for use with a single ACPGUI client. The IP addresses, TCP

Chapter 8 • Using a remote GUI 1032039-0001 Revision C

121

•

ports and names are listed with indexes from 1 to 8. The ACPGUI will not process entries with indexes out of this range. RemoteGUI= dword:CONTROL_VALUE

•

This key is used to indicate whether it is ACPGUI running in the local machine or remote machine. A remote ACPGUI is the TCP client application that controls a ACP process hosted on a different machine. If this key is set to true, only the IRU panel will be left active. DefaultServer=dword:DEFAULT_SERVER_TO_USE If this key is available, ACPGUI will pick this connection to use after the startup.

Operation At startup, the ACPGUI checks the default RemoteGUI key. If the key is not set, ACPGUI starts up in local mode. Then ACPGUI tries to read the DefaultServer. If the key is set, the corresponding server IP and port are retrieved. ACPGUI will try to connect to that IP address and port number. If the connection failed, ACPGUI will display a warning message. At the run time, ACPGUI can be switched to connect to another ACP Server. In order to select a target ACP, open the File Menu and click on Select ACP as shown in Figure 115.

Figure 115: Switch ACP Server from ACPGUI

122


The ACPGUI reads and displays up to 8 ACP configurations, as shown in Figure 116. Once the selection is made, the ACPGUI tries to connect using this configuration.

Hardware

Hardware on page 125 Using a health monitor for ACP testing on page 125 Timing problems on page 128

Use Table 28 to isolate hardware-related problems. Table 28: Troubleshooting hardware

Symptom Some spectrum analyzers do not respond when the ACP Servers program starts.

Possible reason(s) Improperly secured GPIB cables or incorrect configuration.

Solution Verify all GPIB cables are firmly seated. Check that the spectrum analyzer is operating properly: (1) Press the Local Control button and check if the unit goes back into remote. (2)If the problem persists, turn off the spectrum analyzer power, then turn it back on. (4) If the problem persists, disconnect the unit from the GPIB to verify that other units are working.

Spectrum analyzer appears dead and does not respond to the front panel control button.

Using a health monitor for ACP testing

Spectrum analyzer is hung up. The power On/Off button is not working properly.

Unplug the power cord, wait 10 seconds, and plug it back in.

1. Right click the ANTENNA POINT icon located as a shortcut on the desktop. The Antenna Pointing (2) Properties window displays. 2. Select the Shortcut tab. 3. Type /manual at the end of the text string in the Target: field.

Verify that the Pointing Queue (manual pointing) or Automatic Queue (automatic pointing) reads 99. Check the Permanent Logs to verify that all SAs are started. Verify that the dMaxCurPointUser parameters are correct when performing automatic pointing.

•

•

Verify that isolation reads normal measurements: – If a user is pointing or validating, the isolation should be relatively close to the ACP required measurements. – If the users are reading negative opposite to the required value (example -36.5) then ACP has lost its timing and escalation should take place. Ensure proper operation of spectrum analyzer pair(s). If a spectrum analyzer pair has stopped or if one is in question, deactivate and reactivate the pair. Verify calibration measurements in the transient logs. – The total number of SA that are active minus 1.

Timing problems

For ACP HSI (Release 5.x or later) timing issues are typically cause by either LAN failure or a malfunctioning timing unit. When LAN failure is suspected, check the following components: • •

Overview

Overview on page 141 Platform recommendations on page 142 Other recommendations on page 142 Helpful web sites on page 143

Hughes service uses several Windowsoperating Windows operating system platforms in the satellite uplink facility. Certain servers may be exposed to the public Internet. The specific platforms potentially vulnerable to hacker attacks are as follows: • • • • • •

IP Gateway (IPGW) Turbo Internet Gateway (TIGW) Special Services Gateway (SSGW) Dynamic Network Control Cluster (DNCC) TurboPage Server Web Auto-commissioning Auto-com missioning Server (WebACS) (WebACS)

These platforms must be protected from network security threats, such as denial of service (DoS) attacks, since the operation of the entire Hughes Two-way System relies on these Windows-based platforms. The DNCC, SSGW, IPGW and TIGW encapsulate messages using Microsoft Winsock (TCP/IP Stack). To avoid complicated network setups, these components are normally connected directly to the public Internet through the INET LAN. Therefore, these components may be vulnerable to attack since the Windows TCP/IP stack bound to these affected interfaces would respond to ARP broadcast requests from hosts in the public Internet, which would enable hackers to discover NOC platform IP addresses. One solution is to bind the DNCC INET, IP Gateway WAN WAN and ENT interfaces to the A ltaLANA packet driver, which is an Hughes proprietary Windows NIC driver that does not respond to ARP requests. The WebACS WebACS relies on the IIS Web Server on the Windows platform and supports both terrestrial web-based as well as satellite-based auto-commissioning auto-commissio ning (SBC). When using terrestrial web-based auto-commissioning, one of the network interfaces on

Appendix B • Virus protection recommendations 1032039-0001 Revision C

141

the WebACS is connected to the public Internet. It is important to protect the WebACS from compromise since a hacker could potentially gain access to the Oracle database from the WebACS. Like the WebACS, one of the TurboPage Server network interfaces is also connected on the public Internet and is therefore also vulnerable to hacker attacks.

Platform recommendations

These specific recommendations apply to all Hughes NOC platforms that have network interfaces on the public Internet. •

Other recommendations

These measures are also strongly recommended: •

•

• •

142

Use Windows 2000 or above as the operating system plat form (instead of Windows NT). Install latest virus protection software and updates. Ensure the virus protection software is continuously updated. Install latest service packs and security updates from Microsoft. Ensure these security patches are continually updated. For the WebACS, use SSL on the autocommissioning web pages that send sensitive information (such as IP Addresses, email passwords). This is configured in the WebACS from IIS and on the WebSetup software. Disable all non-essential TCP/UDP ports on the NIC that connects to the public Internet. These include (but are not limited to) SNMP SN MP,, Remote Shell Daemon, various Windows services such as Remote Database Services (RDS), RPC, FTP Server, etc. This can be accomplished either by using a firewall and/or by specifically turning off Windows services not required for fo r WebACS WebACS or TurboPage Server operation. Follow all IIS Security guidelines as documented on the Microsoft website. Run the Nessus system vulnerability scanner from http://www.nessus.org and take action to plug any holes identified by the scanner.

Avoid connecting systems to the Internet before hardening them. Do not connect test systems to the Internet with default accounts/passwords. Update systems when security holes are identified. Avoid using telnet and other unencrypted protocols for managing systems, routers, firewalls, and PKI.

Helpful web sites

Do not give users passwords over the telephone or change user passwords in response to telephone or personal requests unless the requester can be authenticated. Maintain and test backups. Avoid running unnecessary services, especially ftpd, telnet, finger, rpc, mail, rservices. Ensure firewalls are implemented with rules that stop malicious or dangerous traffic – incoming or outgoing. Implement/update virus detection software. Educate users about what to look for and what to do when they see a potential security problem. Do not allow untrained, and/or uncertified people to take responsibility for securing important systems.

Appendix C

Configuring ACP timing This appendix discusses the following topics: • • •

Verifying cros-pol interference

Verifying cros-pol interference on page 145 Configuring the FrameIDAdjustment parameter on page 145 Configuring the DelayFrameNumber parameter on page 146

Two timing-related parameters help control when ACP takes its measurement of a CW transmitted by a terminal, for the purposes of verifying the cross-pol interference is minimized and acceptable. • •

FrameIDAdjustment DelayFrameNumber

If these parameters are misconfigured, ACP may trigger the local spectrum analyzers to take a measurement outside the window where the terminal is transmitting its CW, causing the ACP to register no signal and fail the validation procedure. The parameters are affected by the propagation delay from the terminal to the NOC, by congestion in the SGW delivering packets to the terminal's outroute, and by congestion on the Mux LAN where timing signals are received by the ACP.

Configuring the FrameIDAdjustment parameter

The FrameIDAdjustment parameter specifies an offset from the frame number received on the Mux LAN to correct for congesti on on that segment. As the multicast timing signals are received, the frame number is adjusted by the value of FrameIDAdjustment. Currently this parameter has a minimum value of 0 frames. Only positive adjustments can be made. As congestion on the Mux LAN increases, and the frame number packets are delayed, this parameter may increase to account for the actual frame number when the packet is received. However, there is a significant margin available given that the CW is transmitted for 23 frames, and congestion on the Mux LAN would rarely result in even a single frame of additional latency on the timing packets. The test procedure for determining an appropriate value for this parameter is as follows:

Appendix C • Configuring ACP timing 1032039-0001 Revision C

145

1. Attach an oscilloscope to two inputs: the trigger signal from the ACP GPIB, which triggers the spectrum analyzers to begin their sweep, and the TX signal of a DW6000 terminal that performs ACP validation and pulls high when the terminal is transmitting its CW. This coordinates the terminal transmit and the triggering of the spectrum analyzers to capture the wave. 2. Verify that the oscilloscope indicates the relative time difference between the terminal beginning transmission of its CW and ACP triggering the measurement of that burst. However, this does not account for the propagation delay, since measurements are being taken from opposite sides of the satellite network. 3. Set the parameter value such that the relative time difference between T0 (the terminal's transmissio n of a CW) and T1 (the time that the ACP GPIB triggers the spectrum analyzers), corresponds to an average one-way satellite propagation delay. The parameter value selected should ensure that on average, as much of the CW is captured by the spectrum analyzers as possible. Because the increment is 1 frame, or 45ms, a perfect setting does not exist. However, because propagation delay varies based upon geographic location (and, effectively, the quality of the ranging performed by the terminal), there is always some variance. Properly set, the spectrum analyzers should capture 90% of the CW, which is sufficient. Note:

Using this procedure in the Hughes development lab,

it was determined that a value of 1 or 2 frames is acceptable, though a larger sample with terminals in more diverse locations would be useful in determining whether 1 or 2 is closer to an ideal value for a system with terminals across the country.

Configuring the DelayFrameNumber parameter

146

The DelayFrameNumber parameter specifies the number of frames in the future that the ACP will request a terminal to transmit its CW. By design, the setting does not affect the relative timing between the terminal's transmission and the ACP's measurement. It does affect when in absolute time the transmission and measurement occurs. The value selected must ensure that the command from ACP reaches the terminal with sufficient time for the terminal to stop traffic and transmit its CW before the specified frame arrives. For example, if the value is set to 2 frames. By the time the ACP sends its message, the SGW forwards it over the outroute and the terminal receives and


processes the command, the frame during which the ACP expects to measure the CW has already passed. In this instance, the ACP has already triggered the spectrum analyzers, which do not capture any signal. Afterwards, the terminal may transmit its CW with no listeners on the other end, and validation fails. The analytical exercise for calculating the ideal value includes accounting for propagation delay on the outroute, including not only RF delay, but also any congestion on the LAN segments or SGW serving the outroute, which may delay the reception of the command by the terminal. Through operations experience, this value has been raised from its original default value of 4 frames, to 5 frames across the National NOC, which has greatly imp roved the success rate. In an unloaded system, it is likely that a lower value would be acceptable. The DelayedFrameNu mber is used by the ACP as a multiplier of another parameter configured by the operator. The actual formula used to determine the future frame number is: usdFrameNum = usdFrameNum + (ucAllocNum + 1) * (udDelayedFrameNum + 1)

Where the following applies, • usdFrameNum

If a significant number of ACP validations fail with no signal received by the spectrum analyzers, this parameter may require modification. The same test procedure and setup described earlier may be used to determine whether this parameter is improperly set. If the value is too low, the oscilloscope may indicate a large relative time difference, with the spectrum analyzer pass occurring well before the terminal's CW is sent. Or, it may show the spectrum analyzer pass occurring without the terminal ever sending its burst. Increase the value and recheck the oscilloscope to ensure that the events occur in the proper relative time.
