BTS SYNCHRONIZATION In case of S8000/S12000 extension, the BTS 18000 acts as a new site synchronized to S8000/S12000 site. In V15.0.1 the BTS 18000 is just able to be “slave” of S8000 or S12000 master BTS No hardware change. ICM is synchronized with S8000/S12000 CBCF through GPS interface. It’s consists in synchronizing one BTS by another BTS instead of by the BSC through the Abis link. It’s introduced in V15.0.1 in his first version.
3.5.1 PRINCIPLE The principle is to synchronize one or two BTS, called slave BTS, with the synchronization signal received from a third BTS, called master BTS, instead of from the Abis link. The “synchronizing” or “master” BTS receives its synchronisation (SY) from the BSC through Abis link and generates its own GSM time as a “normal” BTS does. The “synchronized” or “slave” BTS get its synchronisation (SY) and GSM time from external signal coming from the master BTS, through a new specific cable. This cable has the same length constraint as the inter-cabinet cable, and the synchronized and the synchronizing BTS must not be more than 10 meters apart. This is why they must be installed closer. The received GSM time is re-generated and sent to the TRX with zero delay so that the radio frames of the slave BTS are in phase with the radio frames of the master BTS. The new cable is a “Y” cable that diverts the signal sent by the main cabinet of the master BTS to its two extension cabinets towards the two slave BTS. It is connected to one IFM of the slave BTS18000 BTS. The master and slave BTS are co-localized. Up to two BTS 18000 slave site can be synchronized with a S8000/S12000 master site. Each BTS 18000 slave site can have normal extension cabinets. A S8000/S12000 site with CBCF can increase his capacity with BTS 18000 cabinet. The BTS 18000 cabinet must be deployed close to the S8000/S12000 main cabinet. It must then comply with same (or better) environmental, dependability, installation requests. The BTS 18000 cabinet can be synchronized with the S8000/S12000 main cabinet CBCF using the existing connectivity. This synchronization is provided through GPS connector to the BTS 18000 cabinet. The ICM is able to detect the synchronization signal type (auto synchronization from CBCF). In V15.0.1 the BTS 18000 is always the slave cabinet.
3.5.2 BTS UPGRADE The simultaneous upgrade of the master and slave BTS allows to reduce the service interruption on the slave BTS (in that case, the outage of the master BTS has then no impact on the slave BTS). Nortel Networks confidential

BTS 18000 GSM Indoor & Outdoor Engineering Rules So, it is recommended to lock the master and slave BTS at the same time and to leave the slave locked as long as the master is not enable again. If master and slave are not upgraded at the same time, the slave BTS will be out of service twice: at the master reset and during its own downloading.
The CMCF phase 1 doesn’t support the synchronization.
A specific cable is needed between the master and slave BTS.
The master and slave BTS must be connected to the same BSC.
It is recommended to the operator to associate the master and slave BTS at MMI thanks to the multi-site feature and to give significant name (from a synchronization point of view) to the master and slave BTS (such as city01_master01, city01_slave02 and city01_slave03).
It is recommended to install the master and slave BTS in that order: 1.
switch off the slave BTS(s) and connect the external SY and GSM time connectors
2.
lock the TRX of the master BTS whose internal link is going to be disconnected to permit the connection of the derivation “Y” cable. ( *)
3.
connect the “Y” cable on the master BTS
4.
unlock the TRX of the master BTS that have been locked in step 2
5.
put the slave BTS(s) in service
(*) This is important to note that the installation of synchronization has an impact on master BTS service: as the internal link between main and extension cabinets has to be disconnected for being replaced by a “Y” derivation cable, the TRX of one extension cabinet (if there is only 1 slave BTS) or of the 2 extension cabinets (if there are 2 slave BTSs) are set out of service.

Table 4.4 : BTS 18000 Indoor Electrical Characteristics The BTS 18000 indoor is proposed into two DC variants: -48V and +24V. Each variant incorporate a single feed direct DC power option. BTS 18000 combo UMTS/GSM is proposed only in -48V variant. The nominal input voltage supply of the BTS 18000 cabinet is +24V DC (+27.0V nominal) or –48V DC (-54.6V nominal) and is depend on DC pre-cabled cabinet variant. Nominal input voltage: +27Vdc
Normal input voltage range: +21Vdc to +31.5Vdc (32Vdc is suitable)
Abnormal input voltage range: From 0V to 21V and from 31.5/32V to 60V, the modules converter does not suffer any damage and is automatically restore to normal service when it recovers from abnormal to normal input voltage. Below 0V the cabinet beakers are forced to shutdown the DC distribution. Nortel Networks confidential

Abnormal input voltage range: From 0 to -40.5 and -57V to -60V, the converter does not suffer any damage and is automatically restore to normal service when it recovers from abnormal to normal input voltage. Above 0V the cabinet beakers are forced to shutdown the DC distribution
CABINET PROTECTION The BTS 18000 distribution system is designed with four separate output connections. Those connections are grouped on one breaker panels. In addition to the main breaker, each group of modules within the BTS 18000 are separately protected by an electrical safety cut-off device, which protects against overcurrents and also disconnects and isolates the connected load from the DC supply. Each module is protected by a specific fuse and provides inrush current limitation. Refer to table 4.3. These breakers are internal to the BTS 18000 Indoor and are protected by an external main breaker refer to [A2] for more details.

BTS 18000 GSM Indoor & Outdoor Engineering Rules The Internal batteries are plugged on the 48V bus of the UCPS DDU. They are protected by a dedicated alarmed breaker. Battery charge is made under UCPS management at power up when rectifiers DC output ramp up is performed. If the AC source or rectifiers fail, the battery automatically are used. Thermal measurement and compensation of the internal battery is managed by the UCPS. The backup times in Table here under are calculated values dedicated only to the Hawker batteries. The values are for a backup of the BTS depending of the radio configuration and therefore correspond to the first threshold. If the AC main fails, the BTS is backed up until the battery voltage is below to 44Vdc. After this time, the DDU cuts off the supply to the RM and the ICM/4U/ABM/ECU remains powered until the battery voltage drops below 42 VDC.

MODULES AND BOARDS
5.2.1 COMMON FUNCTION MODULES (BCF) IFM There are two types of IFM board:
IFM
IFM1
Except for the level of secondary protection and the names that appear on the boards, the two types of IFM board are identical. Throughout this document, the term “IFM” is used in text and graphics. You should interpret this as a generic term that covers both types of IFM board. If it is necessary to distinguish between the two types of IFM board, then this is stated explicitly in the text. The Interface Module (IFM) is used as default in the BTS18000 main cabinet only: it is not present in the extension cabinets.

Page 26/79
BTS 18000 GSM Indoor & Outdoor Engineering Rules The IFM module is composed of a single board with connections on the Interface Back Panel (IBP) and on the front panel. The E1/T1 IFM is a passive board. Active parts are all located in ICM. IFM provides ICM with several status signals (GPS antenna presence (in future), redundancy status). It also provides ABM with a "presence detection" signal and for Inventory. Only one reference of IFM enables to fulfill the following configurations;
E1 or T1 twisted pair.
Single IFM connectivity to single ICM for Quad link capacity.
Dual IFM connectivity to single ICM for Octal link capacity.
Dual IFM connectivity to dual ICM for Octal link capacity with ICM redundancy.
The only function provided by IFM is connectivity:
Quad E1/T1 links from the ABIS (front panel) with secondary protection to local ICM (back panel) and redundant ICM (cross connect connector on front panel).
Quad additional E1/T1 links from the other IFM (cross connect connector on front panel) to local ICM (back panel). This feature is used in Octal ABIS link configuration, whether ICM is redundant or not. IFM provides also to ICM link detection for this additional ABIS link.
External synchronization link from external source (CBCF or GPS antenna (in future), on the front panel) to local ICM (back panel) and remote ICM (cross connect connector on front panel) Note that only one antenna is connected to any one of the two IFMs. IFM provides antenna detection to both ICMs.
Cross connect links between remote ICMs (cross connect connector on front panel) and local one (back panel). This link conveys detection, active/passive, synchro and signaling link signals between both ICMs (similar to S8000/S12000 inter CMCF links).
Note that IFM does not provide ICM with the type of link (E1/T1) detection. This one is done by commissioning switches inside ICM.
Difference between IFM1 and IFM :
IFM board provides a level of secondary protection greater than or equal to that provided by a CSU (NA only). Consequently, IFM is the appropriate board to use if a CSU is not being used (WT) to provide protection. The name on this board is IFM.
IFM1 board provides a lower level of secondary protection than that provided by the IFM board. If a CSU (NA only) is being used to provide protection, then the IFM1 board can be used instead of the IFM board. The name on this board is IFM1. As the IFM1 have the same level of protection than the S8000/S12000’s CPCMI, for EMEA IFM1 can be used instead of IFM.

On one side, it manages interface with ICM, one external front link or two in case of ICM redundancy, in the case of redundant links it is swap immediately from one ICM to the other in case of active/passive change.
On the other side, the bridge manages one internal link for ABM alarm function and 3 internal links to RM modules. Each link includes traffic link and various control signals (reset, Bay Id, status detection) that enable safe operation sequence of RMs. Out of band control information enables ICM to drive the RMs reset.
ALARM COLLECTOR
The ABM has the ability to detect several kinds of cabinet alarms under ICM control, including : Detection of up to 32 Boolean type cabinet alarms. Those signals are open/close loop ones, but only 20 can be used as unprotected alarms and can be used only inside the cabinet or outside the cabinet but only several meters far from the cabinet and never outside the site. They are detected at any time by ABM and reported to ICM. Only the even ABM is in charge of cabinet alarms collection. This position is indicated to ABM by the Radio Interco board cabling. See “ Cabinet alarm detection” here under.
Detection of the digital rack, combiner rack and other modules : •
Under the request of ICM, the ABM can report the result of the presence detection process.
•
Modules presence is detected through a close/open loop signal for those within the ABM digital rack, and the related RF combiners: o
Digital rack modules: IFM, ICM, SPM, and 3 RMs.
o
RF combiners: DDMs, TX Filters modules.
o
Cabinet modules (indoor SICS and outdoor ECU). In the outdoor cabinet, the even ABM also detects the UCPS presence.
•
This feature works regardless of the modules power supply status. The insertion or removal of a module is detected at any time.
•
For the RF combiners, this feature does not provide the difference between the combiner’s type (DDM, TXF). The inventory must be done to get this information.
Inventory of the digital rack, combiner rack and other cabinet modules : •
Under the request of ICM, the ABM can report the result of the inventory process.
•

The ABM has the ability to detect several kinds of cabinet alarms, including: o
door status,
o
outdoor cabinet 4U user rack and ADU.
o
other spare…
Those signals are open/close loop ones, the total number is 20. They are detected at any time by ABM and reported to ICM. Only the even ABM is in charge of cabinet alarms collection.
Alarm polling of the Radio coupling modules including: •
LNA over current detection in the DDMs,
•
VSWR alarms and associated setting of thresholds in the DDMs and TX Filters with the VSWR option.
•
Configurations of by-passable hybrid 2 ways on DDM and TXF.
•
Those alarms are polled by ABM via RICO, through the I2C bus over RS422.
Alarm polling of the cooling system modules including : •
Indoor SICS blowers, filter, power and control board status,
•
Outdoor ECU blowers, filter, damper, heater, power and control board status.
•
Those alarms are polled by the even ABM via RICO, through the I2C bus over RS422.
Alarm polling and SW management of the outdoor UCPS. •
The ABM has the ability to update the UCPS SW release.
•
It can also set up a certain number of parameters inside the UCPS to fit its configuration to the BTS18000 cabinet and Battery type.
•
ABM can also control the UCPS (shut down the rectifiers and force battery operation, force battery equalization, and other TBD…)
•
Those controls are sent by the even ABM via RICO, through the UART bus over RS422.

Each ABM has the ability to detect 8 external protected alarms, and to drive 2 remote controls.
•
Those signals are open/close loop ones. They may be detected or driven at any time by ABM and reported to CBCF/ICM.
•
This function on ABM provides isolation.
SW alarm detection: •
All digital modules and RM have the ability to generate internal and SW alarms, and to report them to ICM via O&M messages. This requires power, digital links and SW to be valid on the modules.
•
This includes UCPS alarms (AC monitoring, DC monitoring, breakers status, Battery status)
5.2.2 RADIO MODULES RM The Radio Module (RM) is a complete GSM/EDGE transmitter/receiver. It is in charge of all processing related to the GSM TDMA. It is designed to support 3 TDMAs (GSM or EDGE). It is logically equivalent to 3 TRX. The RM is able to operate on one sector basis (3 carriers per sector) “O3” mode as well as 3 sector basis (one carrier per sector) “S111” mode. Each radio module is under the control of I CM through the ABM in term of reset. It has permanent access to Bay Id information on the Digital Back Panel (DBP), so it is able to configure itself accordingly. It is interfaced with the ABM module via the digital backplane and provides to ABM a "presence detection" signal and inventory. All those interfaces are hot pluggable: they offer safe operation and prevent disturbance to other links or modules whatever RM operation (insertion / removal, power up/down ...). Back panel access is hot pluggable: provide inrush limiting functions and hot plug signals. The RM TX part consists of three low power transmit RF chains. Each chain processes only one downlink TDMA. The RM TX provides the RM PA part with 3 RF, low level (10 dBm range), modulated (GMSK and 8 PSK), bursted signals. The RM PA part consist of three independent Power Amplifier lines up built on three independent boards. Each line up process one transmit carrier (GMSK and 8PSK modulation). Depending of frequency band, the PA output power will vary. Refer to the RF characteristics table. The RM receive part consists of 6 RF receive chains. Receive chains are grouped by 2 chains (Main and diversity).

TX2 RX0 main RX1 main RX2 main (common) Figure 5.2 : RM module In addition, a RX splitter function is integrated on the RM RX board. It is inserted between DDM and RM RX paths (Main and diversity). It allows splitting DDM RX outputs in order to reach maximum configurations (One input to three outputs split for main and diversity paths). In order to fit both RM configurations (S111 and O3), this function is configurable by RF switches. The commands of switches are provided by the DDM (DC command multiplexed on RF signals on DDM RX RF outputs: automatic RX splitter configuration by RF connection). Furthermore, the RX splitter configuration is sent back to the logical par of the RM in order to allow the BTS to detect the configuration (S111 or O3) of each RM.
S111 mode : allows operation in 3 different sectors : all RF connections are used.
O3 mode : whole module operates in only one sector. Only one main and one diversity RX RF connections is used (RX common). RF split is done inside the module.
At cabinet level three mode of operation are allowed : • O3
mode : all RM modules in O3 mode
• S111
mode : all RM modules in S111 mode
• Mixed
mode : 3 RM modules in O3 and 3 RM modules in S111 mode.

At product introduction the HPRM is proposed only in GSM900 frequency band. The HPRM output power is 60W/45W (GMSK/8PSK) +/- 0.5 dB. Refer to the RF characteristics table.
DDM AND DDM H2 MODULES Two types of couplers exist one DDM type and one DDM H2, one and only one type must be used at any time in one cabinet. The BTS18000 uses, as a standard, DDM (Dual Diplexer Module), for TX and RX coupling/filtering purpose. The diplexer allows to share on a same antenna TX and RX signal. The aim of DDM is to provide TX filtering (out of band spurious and noise suppression), RX filtering (out of band interferers and noise suppression), TX to RX isolation, as well as front end low noise amplification for the receive chain. The figure below shows the block diagram of standard DDM:

The DDM is used in a sector basis with one diplexer for main receive path and the other one for diversity receive path. In addition, in order to increase the transmit capacity of DDM, integrated 2 ways hybrid combiners (H2 coupling) is proposed. These combiners can be bypassed. A front panel switch, allows informing the system of the actual DDM H2 configurations (2 ways hybrid by-passed or not) The figure below shows DDM (H2) block diagram:

Figure 5.5 : DDM H2 block diagram As an option, the DDM shall integrate a VSWR meter on both antenna accesses. This VSWR meter provides three levels of alarms. The corresponding thresholds of alarms are settable on site, through DDM fr ont panel switches. The DDM is also connected to ABM module and provides to it a presence detection signal. It allows ABM to collect alarms, inventory information, and to read VSWR thresholds settings. The DDM with VSWR meter option shall provide the following alarms:
VSWR alarms level 1,2 and 3 (per 2 for each antenna port)
LNA high current consumption (per 2, for each LNA)
Refer to chapter “VSWR CONFIGURATION” for more details
TXF AND TXF H2 MODULES Two types of couplers exist one TxF type and one TxF H2, one and only one type must be used at any time in one cabinet. The TX filter is used as complement of DDM. It is used each time extra transmit capacity is needed without need of receive capacity. It aims to allow direct connection from RM PA output to antenna.

5.2.3 CABINET MODULES SICS (INDOOR ONLY) The SICS (BTS18000 Indoor Cooling System) is considered as an integral part of the indoor cabinet design. The system is installed at the bottom of the cabinet, and accessed through an access lift off panel. One SICS is provided by indoor cabinet. Its inventory and alarms are polled by the even ABM (GSM) and by the cGPSAM (UMTS) refer to [R2] for more details. The SICS provide a vertical upwards air flow that permits forced convection cooling of the electronic equipment housed within the Indoor cabled cabinet. The SICS control is sense the external ambient air temperature and automatically select slow (S1), high (S2) blower speed or full (S3) blower speed. S3 provides 700m3/h air flow. If the ambient external air temperature is below Ts2 and no fault condition is detected by the SICS control, the blower speed selection will be (S1). If the ambient external air temperature is above Ts2 and no fault condition is detected by the SICS control, the blower speed selection will be (S2). Under this condition, the SICS filter clog alarm will be inhibited. If a blower fault condition is detected by the SICS control, the blower speed selection will be (S3). Under this condition the SICS filter clog alarm will be inhibited. It will automatically reset once the slow blower speed (S1) has been re-selected by the control board. The alarms generated by the SICS for the ABM are:
blowers,
blocked air inlet,
control board operation
ECU (OUTDOOR ONLY) The ECU (Environmental Control Unit) is considered as an integral part of the outdoor cabinet design. One ECU is provided by outdoor cabinet. Its inventory and alarms are polled by the even ABM (GSM) or cGPSAM (UMTS) refer to [R2] for more details. The ECU provide a controlled air flow that permits 1400m3/h forced convection cooling of the electronic equipment housed within the Outdoor cabled cabinet. A damper is used to control the internal air temperature of the BTS18000 outdoor cabinet. When fully closed, the damper excludes outside air and air is circulated within the cabinet. When the damper is fully open, there is no recirculation within the cabinet, so, the ECU operates by drawing in ambient air that is then routed through the electronic equipment installed in the cabinet and ejected via outlet ducts situated at the sides of the ECU.

BTS 18000 GSM Indoor & Outdoor Engineering Rules At intermediate positions, the damper is adjusted automatically to give a mix of recirculated and external air to achieve a nominal internal operating temperature. For low external ambient air temperatures, the internal cabinet air temperature is maintained above +5°C by the operation of the primary and/or secondary heater circuits. Even when the doors are open and the risk of the temperature decrease inside the cabinet is present, the operational cabinet temperature is maintained. If the cabinet temperature measurement provides an out of range [0-70°C] value, a CEATS alarm is sent to the UCPS to stop operation of all radio and digital modules. The other alarms generated by the ECU for the ABM are:
blowers,
heaters,
damper motor,
blocked air inlet,
control board operation
The power connector provides:
AC input power supply for the heaters (2800 W max).
48V DC floating supply (360W max include in the DC power consumption tables).
UCPS (OUTDOOR ONLY) The Univity Compact Power System (UCPS) is composed of four basic building block components: Rectifiers, the CCU, the DDU, and the Shelf.
The Rectifier is the AC to DC power conversion component of the UCPS. Up to five rectifiers receive AC power directly through the passive Shelf AC distribution. It interfaces with the DDU for DC output and the CCU for control.
The CCU pools power system alarms between ABM and the UCPS external components, the DDU and the rectifiers. The CCU HW and SW enable dual control links in the combo version. Two version of CCU are existing, one for GSM only and one for GSM/UMTS compatible with combo cabinet.
The DDU provides the DC distribution, over-current protection, and output disconnects to enable BTS and cabinet temperature and voltage management. The BTS18000 DDU is the same whatever the configurations (full GSM, combo GSM/UMTS and MCPA versions).
The Shelf is a passive backplane shelf which provides the necessary interconnect for the Rectifiers, the CCU and the DDU. The Shelf is a single version, common UCPS component.
One UCPS is provided by outdoor cabinet. Its inventory and alarms are polled by the even ABM (GSM) or cGPSAM (UMTS) refer to [R2] for more details. The UCPS performs power system operation such as

ALPRO Like for S8000/S12000 products, optional secondary protection on external, user alarms and remote controls is provided by the addition of one ALPRO box per ABM. The same ALPRO boxes is used for S8000 and S12000 indoor can be mounted on top of the BTS18000 indoor cabinet and provide 8 or 16 protected alarms and 2 or 4 remote control secondary protection. Inside the outdoor cabinet, the ALPRO box is packaged in a new mechanical format similar to UMTS iBTS one. This new ALPRO 2 alarm kit is proposed to provide, like ALPRO, 8 external alarms and 2 remote controls and their secondary protection against electrical perturbances that could occur between BTS 18000 Outdoor and customer equipment. This kit is inserted inside the cabinet between the ABM and the bulkhead. As the BTS 18000 Outdoor can have one kit per ABM board, up to 16 external alarms and 4 remote controls could be protected. Rule :
ALPRO or ALPRO 2 is mandatory if the customer intends to connect his external alarms to the BTS in order to monitor them at OMC.
In case of BTS S8000/S12000 swap with BTS 18000, customer and/or regional engineering team must check external alarm connection presence. o
For Indoor world wide, existing ALPRO can be re-used.

RADIO MODULES ENGINEERING RULES GUIDELINES The radio modules are:
RM module
RF combiners: DDM, TX filter, DDM H2 and TX Filter H2.
5.4.1 RADIO MODULE RM and HPRM modules provisioning depends on two main parameters of radio configuration:
Configuration type: Omni-sectorial, bi-sectorial or tri-sectorial configurations
Number of carriers per sector
Rules of provisioning are:
6 RM max. or 6 HPRM max on a BTS 18000 indoor or outdoor
Three RM or HPRM max per ABM
RM carrier’s capacity max.: 3; HPRM carrier’s capacity max : 2
Two configurations available at RM level: tri-sectorial S111 or Omni-sectorial O3. Nortel Networks confidential

Two configurations available at HPRM level: bi-sectorial S11 or Omni-sectorial O2.
5.4.2 RF COMBINERS RF combiners deployment will vary following the RF configurations and the TX coupling type. The choice of RF combiner’s type is mainly driven by the desired antenna output power and number of antenna per sector. The BTS 18000 indoor or outdoor is limited as follows for combiner space:
BTS 18000 combiner max. capacity: 18 slots
One DDM (even DDM H2) needs 3 slots and one TXF (even TXF H2) needs one slot. The RF combiners general provisioning rules are as follow (for DDM and DDM H2) :
DDM provisioning is driven by RX path need: •
only one DDM is required per sector for up to 9 carriers within a cabinet
•
one DDM treats one main receive path and one diversity receive path
•
No split between sector is allowed for DDM
TXF is used for transmit capacity upgrade: it avoids the use of extra DDM if no RX capacity is required
No frequency variant mixed at shelf level.
Even (resp. odd)” combiner rack shall be connected to “even (resp odd)” ABM in term of inventory & alarm. The even combiner rack is located in the upper position in the indoor cabinet, left position in the outdoor one.

POWER CONFIGURATION : ATTENUATION & BSTXPWRMAX Two parameters affect the output power at the antenna connector of the BTS. They are called attenuation and bsTxPwrMax. They act together to give a real output power.

BTS 18000 GSM Indoor & Outdoor Engineering Rules Pc= bsTxPwrMax+ DLU/OMC attenuation
Attenuation
The static attenuation is coded on 4 bits. With the SOC field, the attenuation for the site can vary from 0 to 12 dB (n = 0 to 6) assuming that if the value is set to 0 the attenuation taken into account is the one specified in the DLU, else the value taken into account is the one given at the OMC-R HMI. The attenuation parameter is a class 2 parameter whose value depends on the BTS configuration. The HMI at the OMC-R allows to set its value only at site level whereas the DLU can adapt it to the cell level. That is the case for the DLUs built for heterogeneous coupling. The DLU attenuation is defined at the cell level. As the HMI attenuation parameter applies to the whole site, not respecting this rule would lead to a difference between the power instruction in the cell with a different coupling system and the real power at the antenna output.
bsTxPowerMax
bsTxPwrMax is a class 3 parameter which is the maximum theoretical level of BTS transmission power in a cell. It can be modified at any moment by the operator through the ABIS CELL MODIFY REQUEST message. It can be set at cell level. (setting different values for the different cells construct different coverage areas.) The consistency of the maximum value specified for bsTxPowerMax and the maximum Tx power is always checked and can lead to NACK message. For the lower limit, one must be aware that if the operator sets a lower value, there is only an alarm on the BTS but the BTS is still running with the old value. To observe the failure of this modification, the operator has to verify this notification. At the next failure, the BTS could not restart. In case of heterogeneous coupling systems using the DLU attenuation, bsTxPwrMax has to be set to different values in each cell to be able to transmit at full power at each PAs outputs. However, if a global value of bsTxPwrMax is defined for the whole site, be aware to use a value that can be common to the different types of coupling systems otherwise, a Nack message will rise. The following table defines:
The coupling attenuation for each type of configuration
The range of power accepted by the different RM types
The TX static output power (configured by 2 dBm steps) depending on the bsTxPwrMax consign at OMC-R. The unreachable consigns are grayed and noticed “nack”.

TEI AND TRX ASSOCIATION
6.3.1 TEI CONSTRAINTS
To be able to manage up to 54 TRX (BTS 18000 in S18-18-18 configuration), the TEI is coded on ABIS interface on 7 bits. This impacts OMC, BSC2G and BSCe3.
One RM always supports three consecutive TEI TRX numbers; if only one TRX is configured on one RM, the two other values are reserved and so, not used by an other RM.
(*)
(*)
The TEI supported by one RM must have values that are consecutive in the tables given here after : example, for shelf 1, TEIs 38, 39 and 14 are considered as being consecutive.
In one RM, the first TEI (TEI 38 in the previous example) is always associated with the first transmit path, the second TEI (TEI 39) is always associated with the second transmit path and the third TEI (TEI 14) is always associated with the third transmit path.
Some of the TEI of the RM can be configured as spare, in order to be used as spare TRX in case of failure of one of the other. This defense mechanism still exists and is defined exactly the same way they are on S8000/S12000. The Nortel Networks confidential

For outdoor BTS 18000: Shelves 1 and 2 are in the main cabinet (shelf 1 is left and shelf 2 is right); shelves 3 and 4 are in the first extension (shelf 3 is left and shelf 4 is right); shelves 5 and 6 are in the second extension (shelf 5 is left and shelf 6 is right).
6.3.3 NUMBER OF ABIS TIMESLOTS Radio Site mask rules are the following for BTS 18000 sites:
One LAPD can carry signalling of 9 TRX maximum
For a Site with 9 TRX or less, only one LAPD is necessary
For a Site with more than 9 TRX, LAPD dedicated to a Cell are used (never several Cells on the same LAPD in this case). Nortel Networks confidential

BTS 18000 GSM Indoor & Outdoor Engineering Rules The BTS 18000 product requires either one or two LAPDs per cell ie. maximum 6 LAPDs per site. A recommended rule for an easier upgrade way is to allocate 1 LAPD per cell even if the number of TRX is lower to 9.
EX : 1S6-6-6 could have 3 LAPD instead of 2.
The SITE TEI value for a greenfield BTS 18000 BTS is 0 to 9. That range is different from other BTS products. So a new control has to be done at OMC-R in order to verify the SITE TEI.
6.4.
EDGE For greenfield BTS 18000, each TRX supports up to 10 DS0 (RM supports up to 10 DS0 per TRX; ICM supports up to 10 DS0 per TRX). The EDGE capability is provided by the BTS. The BSC or OMC-R doesn’t have to control it.
6.5.
SITES SYNCHRONIZATION The site synchronization feature allows synchronizing an ICM by a CMCF_ph2 (located in a S8000 or S12000 site). The BTS 18000 is ready for synchronization. Refer to “BTS SYNCHRONIZATION” chapter.
6.6.
VSWR CONFIGURATION The VSWR embedded in a DDM or TxFilter combiners manages 3 fault levels corresponding to 3 VSWR thresholds:
First level is reported to the operator as a warning,
Second level is reported as a major fault,
Third level is reported as a major fault and associated TRX are considered as no more working; if possible, defenses are performed by the BSC.
The thresholds can be configured with a hardware switch that is in front side of the DDM module. Default threshold values are configured at factory. The configuration switch has three possible states. Each state corresponds to a 3 thresholds set. The thresholds values apply to the both VSWR embedded in the DDM. The switch allow shifting the 3 thresholds of a same amount. Three shift values are allowed: 0, 2 and 4dB and correspond to the following level for VSWR alarms: Default switch position (0 dB)
2 dB switch position
4 dB switch position

HARDWARE CONFIGURATIONS MANAGEMENT Each hardware BTS configuration is defined in a specific file called DLU of the BTS software. The introduction of a new BTS configuration requires downloading of a new BTS software including a new DLU. Dynamic management provides an automatic upgrade of the OMC-R file, listing all BTS DLUs thanks to the file that lists all the DLUs included in the BTS software load. BTS’s EFTs contain this the dlulist.txt file. It allows to easily introduce new BTS configurations, which require only a new DLU description, without OMC-R patches and without OMC-R stop/re-start avoiding service interruption. The hardware configuration is given to the software thanks to the DLU mechanism. As many configurations reference as hardware configuration are introduced. Each configuration reference is described by a 3 character code: one letter and 2 digits. New letters are introduced for greenfield BTS 18000 configurations: one letter for indoor variant; one letter for outdoor variant. All Indoor and Outdoor configurations are stored in the same DLU file. MCPA configuration needs a specific configuration file, refer to [R1].
6.8.
DROP & INSERT The BTS 18000 BTS supports the Drop&Insert function exactly the same way the S8000/S12000 does: the BTS is transparent for all external PCM TS not used for its own radio traffic or signaling. It also avoids auto-synchronization. As a consequence it can be inserted in a BTS chain or a BTS loop. The Drop&Insert installation rules remain the same:
BCF TEI are ordered increasing in the chain or loop
External PCM_in are even PCM; external PCM_out are odd PCM.
A switched off BTS 18000 BTS is blocking (similar to CBCF), because the IFM module hardware contains no relays. A power supplied BTS 18000 is transparent for other BTS in the chain or loop.

BTS 18000 GSM Indoor & Outdoor Engineering Rules 3) Choose the RM mode in keeping in mind the upgrade path, in order to have same DLU during the upgrade. This minimizes the on site manipulation and intervention. 4) Then choose the best adapted DLU for this configuration. For help take into account :
The number of sectors per cabinet which correspond to the desired configuration.
The physical configuration of the cabinet which is the nominal repartition per sector of the RM module for a given DLU.
All this determine the best choice for the desired configuration 4) Take into account the GENERALS and SPECIFICS RULES regarding the chosen configuration. Refer to the chapter CONFIGURATIONS ENGINEERING RULES. BTS 18000 permitted configurations and associated DLUs are given hereafter.

Table 7.18 : BTS 18000 dualband tri-cabinet tri-cabinet configurations with RM
7.8.
CONFIGURATIONS ENGINEERING RULES
7.8.1 GENERALS RULES
Be careful do not exceed the "physical configuration" of the DLU used
The authorized depopulated configurations in bi and tri cabinet must respect the mono-cabinet depopulation of the DLU used
In V15.0.1 the BSC e3 is limited to 16 TRX per Cell and 48 TRX per site so be careful to the max BTS 18000 configuration. In dual band be careful to this limitation, is 16 TRX per sector for each frequency but 16 TRX for both frequency with mono BCCH
Configuration in bi and tri cabinets who allows extension with omnidirectional and/or bisectorial cabinet, must be provided and completed with one or two sector equal to zero. That to have the right RM position inside the cabinet and the right TEI attribution. That’s give also the right way for sector extension. o
EX : 2S3-9-12 = 1S3-6-6+1S0-3-6 1S3-6-6+1S0-3-6
TEI description : o
TEI separated by a comma "," means that are TEI of the same RM and TEI separated by a dash "-" means that are from different RM modules.
7.8.2 SPECIFICS RULES RULE 1 :
Could be depopulated depopulated per sector 1S6-6 -> 1O1 with RM O3 and 1S5-5 -> 1O1 with RM S111. Same with HPRM.
RULE 2 :
For the configuration between O1 and O6 the RM n°3 is used as first RM. Be careful to the TEI. Samr with HPRM.
RULE 3 :
The unequilibrated mode configurations are not fixed. The ones describe in the table are typical ones, and is here to give an idea and to indicate the availability of the unequilibrated mode configuration. The sectors can have different carrier quantities with the same DLU in keeping similar configurations. EX: 369-936-693, etc…. That meant the higher sector Nortel Networks confidential

BTS 18000 GSM Indoor & Outdoor Engineering Rules can be the first, the second or the third one. Just refer to the “BTS 18000 TEI and TRX mapping” table in chapter 6 and to the scheme corresponding to the DLU at the end of this chapter, to choose the right TEI. Example : With the 1S6-12 unequilibrate mode configuration with the N/M01 DLU, we have RM0 and RM3 TEI’s in sector one and RM1, 2 and RM4, 5 in sector 2. But we can also have 1S12-6 with RM0, 1 and RM3, 4 in sector one and RM2 and RM5 in sector 2. Refer the scheme for the 1S6-6-6 N/M01 and group the RM modules to build the 1S6-12 or 1S12-6. RULE 4 : N03 and M03 never use TxF H2, only DDM H2 are used. So be careful when you have choice between N/M03 and other other DLU. Using this DLU must be very specific, because that the upgrade path is quickly blocked. RULE 5 : N33 and M33 never use TxF, only DDM are used. So be careful when you have choice between N/M33 and other DLU. Using this DLU must be very specific, because that the upgrade path is quickly blocked. RULE 6 : The maximum quantity of TRX for these configurations in mono cabinet is 1S5-5-5, in normal utility conditions with the possibility to have all options. If maximum configuration in 1S6-6-6 is wanted, take care that only, and only one ALPRO could be installed, due to the position of TxF addition. So only 8 externals alarms can be connected. The S6-6-6 configurations are only available for the Outdoor cabinet

DEFINITIONS 8PSK
8 states Phase Shift Keying modulation. The modulation used for EDGE is a 8PSK with an additional constant shift of 3 Π/8 at each symbol change.
Abis
ETSI generic name of BSC-BTS interface. The Abis covers both the physical interface (PCM) and the protocols. Protocols are splitted in a TMG part and an O&M part, the former being mostly compliant with GSM 08.58, the latter being NMC proprietary.
Abis PCM
2.048 Mbit/s for E1 (or 1,544 Mbit/s for T1) physical link (HDB3 or B8ZS) where the clock is synchronous with the radio transmission.
Cabinet/shelf/rack In the document, the term cabinet point out the total enclosure of the equipment, as well as the entire equipment (enclosure+cabling+modules). Two versions of cabinet is described in this version of document BTS18000 Indoor cabinet and BTS18000 Outdoor. The term Rack is used to point out two physical sub-assembly: •
Combiner Rack: one stage of combiners equipments
•
Digital rack: one stage of digital and radio modules.
The term Shelf is used to point out the association of these two racks. Cavity
An association of passive RF frequency selective filters to combine a number of Transceivers onto one antenna. It includes a Diplexer unit.
dB
decibel. Dimensionless, it expresses a ratio.
dBm
decibel milliwatt. A logarithmic unit to express a power level, with reference to 1 mW. In radio, this reference is taken on a 50 Ohm load, while in telephony this is 600 Ohm.
Diplexer A frequency band selective circulator. Used, as any multiplexor, to minimise the number of physical transmission lines. For radio, transmission line are antenna system. DLU
A DLU contains all the hardware characteristics of the configuration of the BTS. This parameters are downloaded to the BTS and are used at initialisation stage.
