System Module operation and main blocks

2 2.1

System Module operation and main blocks Operation The Flexi System Module hosts the telecom control, system operation and maintenance, baseband application, transmission, and power distribution functionality. The System Module can also act as a System Extension Module operating in a baseband extension mode. The System Module provides the following BTS external interfaces: .

BTS Site Element Manager

.

external interfaces towards the RNC (Iub)

.

three external interfaces towards RF

.

site support system interface (for example, battery back-up)

.

auxiliarity interface (customer-specific 10/100 Mbps Ethernet port with overvoltage protection)

.

auxiliarity interface 1 Gbps Ethernet for future expansions

.

external alarms and controls interface (customer-specific alarms)

.

external synchronisation input interface

.

external synchronisation output interface

The System Module has an integrated BTS clock that distributes the synchronisation clocks to other BTS modules. The System Module hardware is HSDPA and HSUPA compliant. The System Module uses nominal 48 V DC and distributes it on to RF and System Extension Modules. The System Module includes integrated fans.

The System Module can be used, for example, for the following software functionalities: .

BTS level O&M processing (BTSOM)

.

resource management

.

node B server

.

NBAP handler

.

user plane management

Flexi WCDMA BTS control and multiplexing This functionality is responsible for BTS control and management, system clock generation and distribution to other modules and sub-modules. The functional distribution of this functionality is as follows: .

.

.

.

.

Control MCU and clock generation: This includes the NBAP termination, telecom and overall BTS control functionality, system O&M functionality, external site support system and other equipment control. It generates system reference clock and frequency reference for synchronising with other BTS. External interface block: This block facilitates the external interface for external equipment control. Summing and multiplexing functionality: This functional block is used for data routing between the radio modules and the baseband. RF Module interface: This logical functional block is responsible for providing output/input interface to or from a maximum of three RF Modules. Baseband extension interface: This logical functional block is responsible for providing output/input interface to or from the System Extension Module.

The signal comes from the Flexi transport part, which is locked (PLL) to the Iub interface. The signal in MDR14 is asymmetric: connect the core of the coaxial cable to pin 7 and cable shield to GND (e.g. pin 14).

Testclk_out: 10MHz system clock (LVTTL)

.

The signal comes from BTS OCXO which is used for air I/F generation => reference for the RF measurement equipment. Note: the BTS OCXO is not in the PLL mode to the Iub, the locking is very loose due to air I/F stability reasons. The signal in MDR14 is asymmetric: connect the core of the coaxial cable to pin 11 and cable shield to GND (e.g. pin 10)

System Module as an extension module

7


7.1

System Module as an extension module The System Module can be used as a System Extension Module operating in a baseband extension mode to add channel capacity. In this case, it is connected to the System Module by connecting two optical cables and a DC cable. These items are provided with Flexi System Extension Kit (FSKA). When the System Module is used as a System Extension Module operating in a baseband extension mode, a transmission sub-module is not installed. Instead, a dummy transmission sub-module is installed to provide IP protection. This item is also included in Flexi System Extension Kit (FSKA). When the System Module is used as a System Extension Module operating in a baseband extension mode, external synchronisation input connectors cannot be used. Synchronisation is provided by the System Module. For installation instructions, see the Installing Optional Items document. For commissioning instructions, see the Nokia Flexi WCDMA BTS Commissioning document. When integrating the System Extension Module to Flexi WCDMA BTS, no commissioning is required. Once the System Extension Module has been connected to the System Module and powered up, the auto detection functions of Flexi WCDMA BTS detect the System Extension Module and connect the System Extension Module to the normal operation of the BTS. As for software requirements, the auto detection requires that WN4.0 BTS SW exists and is active both in the System Module and System Extension Module to be connected to.

The System Extension Module provides a basic capacity of 32 CE without the channel capacity licence. Enabling more CE capacity of the System Extension module for service requires that the channel capacity licence (RAN912 Channel Capasity LK) with sufficient capacity is downloaded to the BTS.

7.2

FPFA interfaces Power is distributed from Flexi Power Distribution and Fuses (FPFA) to the transmission sub-modules in the System Module. See the following figure for the location of the FPFA.

Figure 22.

Location of the FPFA and transmission sub-module in the System Module

There are two types of FPFAs available: .

A101 version

.

A102, A103 or later

There are differences between these versions in the inner connections. FPFA inputs and outputs With all FPFA versions, always use busbar input connector (with screw connection) for input connections of the FPFA and when connecting power to the extension module.

DN7084495 Issue 5-0 en 21/01/2008


The multibeam connectors in the front panel must not be used as input to the FPFA. The multibeam connectors are not hot-plug connectors. Always switch off the power via the on/off switch on the FPFA front panel when connecting or disconnecting the RF or Extension module to the FPFA.

The above figure illustrates the System Module core version 101 and 102. Please check the core version from the type label indicated in the previous picture. LED indications for RF1, RF2, RF3 and EXT LEDs (4) on the front panel indicate the state of the circuit breakers (CB) if load (for example the RF Module or the System Extension Module) is connected to FPFA output. When lit, the LED is red. LED on: .
