Chapter 1 How to use this manual

1.1 Introduction1.1.1 Corrective maintenance

Corrective maintenance for a BTS 18000 has two steps:

• Locate and identify faulty equipment. Nortel GSM BTS 6000 and18000 Fault Clearing (411-9001-161) provides fault location andtroubleshooting information. The alarms and notifications describedin Nortel GSM BSS Fault Management—Maintenance Principles(411-9001-039) also provide detailed information and guidance.

• Replace faulty equipment. This manual describes the replacementprocedures.

Whenever a network component detects a fault, it sends an alarmto an Operation and Maintenance Radio (OMC-R). A fault numberidentifies each alarm. Nortel GSM BTS 6000 and 18000 Fault Clearing(411-9001-161) contains procedures associated with each fault number.

Faulty equipment can also trigger several alarms. Nortel GSM BSS FaultClearing—Advanced Maintenance Procedures (411-9001-105) providesprocedures to help an operator locate the fault. It also helps an operatorresolve abnormal operation in a Base Transceiver Station (BTS), aTransCoding Unit (TCU), a Base Station Controller (BSC), Pulse CodeModulation (PCM) links, or BTS entities.

1.1.2 Preventive maintenanceBy performing periodic preventive maintenance, the user can testequipment that does not directly trigger any alarm at the OMC-R. However,the execution of these procedures may trigger alarms at the OMC-R.

Preventive maintenance for a BTS 18000 involves two steps:

• Test the equipment.

• Replace any faulty equipment. This manual describes the replacementprocedures.



.

14 Chapter 1 How to use this manual

1.1.3 Intervention restrictionsThere may be a lapse of time between the identification of the alarm at theOMC-R and the time the operator responsible for the intervention arrives atthe site.

The operator must be synchronized with the OMC-R (by telephone) beforean on-site intervention, in the following cases:

• isolating procedure

• intervention because alarms are triggered at the OMC-R

• completion of an on-site intervention

• return to service procedure

Chapter 3 Description of a start-up

3.1 IntroductionThis chapter describes the elements linked to a BTS 18000 start-up.The procedure for powering on and off the BTS 18000 is detailed, and aflowchart presents the BTS start-up.

The behavior of the LEDs for each module is described in Chapter 3 BTS18000 cabinet description. See Nortel GSM BTS 18000 Fundamentals(411-9001-160).

3.1.1 External BTS 18000 synchronization on GPS3.1.1.1 Start-upThe start-up of a BTS 18000 that has GPS equipment installed is asfollows:

• The BTS power-up induces a power-up of the True Position GPSreceiver (TMU or LMU + EIU):

— During the start-up of these modules (which can take up to30 minutes), their LEDs blink in yellow. Once the start-up iscomplete (and the modules are available as a source of GPSsynchronization), these LEDs stop blinking and become green.

• The BTS starts synchronized first on its internal clock and then on theBSC using the Abis link.

— If GPS synchronization has been selected (during configuration),the OMC-R requests the BTS 18000 to synchronize on GPS.

— If the GPS equipment is still in its own start-up phase, the BTSremains synchronized on Abis until GPS becomes available.Consequently, there can be delay of up to 30 minutes between theactivation of the GPS synchronization function on the OMC-R andits actual implementation by the network.

— Once GPS becomes available, radio traffic is lost while the BTS18000 synchronizes onto GPS.



.

36 Chapter 3 Description of a start-up

3.1.1.2 ICM LED managementIf GPS synchronization is being used, the active ICM LED behavior is asfollows:

• If the BTS 18000 is synchronized on GPS, the G LED is ON (green)and the four SYN LEDs are ON.

• If the GPS has been lost (return to holdover mode): the G LED is ON(green), the H LED is ON (red), and the four SYN LEDs are ON.

• When the GPS comes back, the H LED is switched off only after theinternal clock is in phase again with GPS.

• When the ICM detects the synchronization signal again (from the GPSreceiver or from the master BTS), four SYN LEDs blink three times.

For a detailed description of the ICM LEDs in this case, see Nortel GSMBTS 18000 Fundamentals (411-9001-160).

3.1.1.3 Power-offAny maintenance that requires a BTS power-off, will lead to a loss of GPS.At BTS restart, the GPS equipment will perform a cold start-up.

3.1.2 External BTS 18000 synchronization on a master BTSIn this case, the BTS 18000 can only be the slave BTS; it cannot be themaster. The master BTS can be an S8000 BTS or S12000 BTS. It is alsoreferred to as 8 kHz synchronization.

3.1.2.1 Start-upThe start-up of a BTS 18000 that uses external BTS synchronization is asfollows:

• If the master BTS is already available, the slave BTS 18000 startssynchronized on the master.

• If the master BTS is not available (the associated alarm is"Master synchronization unavailable"), the slave BTS 18000 startssynchronized on its internal clock and then on the Abis link.

• If the master BTS becomes available later, the slave BTS 18000 thenresynchronizes onto the master BTS. Radio traffic is lost during thisresynchronization.

3.1.2.2 Master BTS becomes unavailableIf a slave BTS 18000 is synchronized on a master BTS and the masterbecomes unavailable (the associated alarm is "Loss of master SY"), theslave BTS 18000 continues operating using Abis synchronization.

When the ICM detects the synchronization signal again (from the GPSreceiver or from the master BTS), four SYN LEDs blink three times.



.

3.1 Introduction 37

3.1.2.3 Loss of Master GSM timeIf the slave BTS 18000 loses the external GSM time (the associated alarmis "Loss of master GSM time"), the slaves remains synchronized on the 8kHz synchronization. For more information, see case 3 in Nortel GSM BTS18000 Fundamentals (411-9001-160).

.

4.3 Checks at the OMC-R 55

4.3 Checks at the OMC-R4.3.1 Preliminary checks before performing preventive maintenanceprocedures

Preventive maintenance procedures can be performed only when there areno alarms on the equipment concerned.

Before taking any action, check the ’’OMC-R Browser’’ browser windows atthe OMC-R, which provide a means of graphically monitoring the network.

When the graphical elements of the display are gray, no alarms are active.The preventive maintenance procedures can be performed.

4.3.2 Final checks after having performed preventive maintenanceprocedures

After having performed the preventive maintenance procedures, check thatthe network has resumed its correct operation.

The graphical objects must appear without any alarm in the ’’OMC-RBrowser’’ browser windows at the OMC-R. The preventive maintenanceprocedures are complete.

If there are alarms on the graphical objects concerned, check the conditionof the site using the ’’Display all’’ command on the btsSiteManager object:

• If the operationalState is ’’enabled,’’ clear the alarms to complete thepreventive maintenance procedures.

• If the operationalState is ’’disabled,’’ set the btsSiteManager object to’’locked’’ and then back to ’’unlocked,’’ and then perform the ’’Displayhardware information’’ command of the btsSiteManager object:

— If all equipment is operating, clear the active alarms. Thepreventive maintenance procedures are complete.

— If certain items of equipment have failed, see the replacementprocedures.



.


4.4 Site state change alarm at the OMC-RIn some faults cases, the BTS is unable to send alarms to the OMC-R

A "site state change" alarm displayed at the OMC-R indicates a loss ofsite.

4.4.1 BTS stateThis happens when the mains power supply is not present

The following elements may be involved:

• circuit breakers

• high temperature and low temperature thermostats

• CCU or ADU module (BTS 18020 and BTS 18020 NG)

• power supply rack (BTS 18020 and BTS 18020 NG)

4.4.2 On-site checking procedures (for BTS 18020 and BTS 18020 NG)

Step Action

1 Safety instructions

DANGERElectric shockThe BTS remains supplied with the mains powersupply, so take care while handling the equipment.

2 Check the mains power supply with a voltmeter at the AC input.

a If power is present, go to step 3.

b If there is no power, check the site circuit breaker.

3 Check that the circuit breakers on the ADU module are in the "I"position.

4 Check that the circuit breakers on the DDU module are in the"I" position.

In case of a new break when switching on a circuit breaker,disconnect all modules connected to that circuit breaker and tryagain

a If there is no new break, one of the modules is the source ofthe problem.

b If there is still a break when switching on the circuit breaker,replace DDU and power supply rack of UCPS. For moreinformation, see 5.2.13 “Replacing a UCPS rack and DDU(BTS 18020)” (page 131).

f Remove the fixing screws.

g Extract the IBP board.



.


h If the cabinet containing the IBP is pre-Release 07, removethe spacer shown circled in yellow in Figure 40 "Pre-Release07 cabinet (designed for IBP)" (page 124) as this will preventthe user from installing the CIBP. When installing the CIBP,the pillar circled in yellow in Figure 41 "Cabinet with CIBPinstalled" (page 125) will not be present, but the CIBP can stillbe installed (and fasten it using the other screws).

i If the cabinet containing the IBP is post-Release 07,the spacer circled in yellow must be moved in Figure 40"Pre-Release 07 cabinet (designed for IBP)" (page 124) fromits current position to the position shown circled in blue.When installing the CIBP, its position will be that showncircled in yellow in Figure 41 "Cabinet with CIBP installed"(page 125).

4 Insertion of the CIBP board

a Connect the DBP-to-CIBP cable to the new board and insertthe new board.


c Connect the DBP-to-CIBP cable to the DBP.

d Reinstall guide plate.

e Insert the radio module that was 16 Pnext to the guide plate.See the appropriate procedure (Replacing a Radio Module(RM/MPRM/HPRM/HPRM3T)).

f Insert the IFM/IFM1 and ICM. See 5.2.1 “Replacing anInterface Control Module (ICM)” (page 67) for the appropriateprocedure for the ICM and 5.2.3 “Replacing an InterfaceModule (IFM/IFM1)” (page 78) for the IFM/IFM1.

g Connect the cables to the radio module, IFM/IFM1, and ICM.

With the CIBP, there is no need of a cross connect cable (for theICMs). The D link cables have different lengths. The shared Abiscable is replaced by an Asymmetrical Shared Abis cable (if thereare two IFMs). See Figure 38 "IFM, ICM, and ABM cables for aCIBP/DBP configuration" (page 122).

The user must ensure that the Asymmetrical Shared Abis cablehas been connected with the correct polarity (the end markedIFM-0 connected to IFM-0, the end marked IFM-1 connected toIFM-1).

5 Power on BTS. See 3.2.1 “Power-on of the BTS 18010/BTS18010 NG2” (page 38), 3.3.1 “Power-on of the BTS 18020”(page 40), or 3.4.1 “Power-on of the BTS 18020 NG” (page 43).

Defense against CIBP or IBP mis-cablingThis section describes the various impacts of mis-cabling IBP and CIBPconfigurations and the associated defense mechanisms.

CIBP configuration versus IBP configurationThe maximum physical implementation in a CIBP-based BTS18000 is thesame as an IBP-based one except:

• Both ICMs must be slotted in the even CIBP. The odd CIBP hosts onlythe additional IFM.

• If IFMs, ICMs, and cables are installed on CIBPs as in IBPs, both ICMswill start active in simplex mode.

• Asymmetrical Shared Abis cable between the IFMs.

• No inter-CIBP and inter-IFM cables

A CIBP enables the use of ICM redundancy within a single digital shelfcabinet (but ICM redundancy removes the SPM-linked evolutions). TheCIBP/DBP interconnection architecture is shown in Nortel GSM BTS18000 Fundamentals (411-9001-160).

The three slots for each CIBP are the following:

• IFM in slot 0

• ICM in slot 1

• optional ICM or SPM in slot 2

The CIBP also interconnects to DBP (inventory and power).

Case 1: IBP configuration mis-cabled as a CIBP configuration TheIFM in slot 0 and the first ICM in slot 1 will act normally in a simplexconfiguration as long as the inter-IBP cable is correctly cabled to thesecond IBP or to the IBP terminator.

However, it is physically impossible to slot a second ICM in anIBP backplane (due to keys). If the user tries to implement a CIBPconfiguration on an IBP-based cabinet, inserting the second ICM is notpossible.

Case 2: CIBP configuration mis-cabled as an IBP configuration Thecorrect cabling for a CIBP configuration is shown in Figure 38 "IFM, ICM,and ABM cables for a CIBP/DBP configuration" (page 122).



.


It is physically possible to mis-cable a dual CIBP configuration (as if it wasa dual IBP one):

• There is one IFM for each CIBP in slot 0.

• There is one ICM for each CIBP in slot 1.

• There is a Shared Abis and a Cross Connect Cable between the IFMs.

• Each ICM will start in active mode.

• Each card is seen in simplex mode in the even position with all correctdetection signals.

• ABM D-LINK selection locks on the even ICM so the odd ICM isisolated from the ABMs.

• Visual check of the ICM LEDs displays activity on both ICMs andinconsistency in external PCM LEDs between both ICMs, whichis abnormal and should be detected by the technician on site.For more information, see Nortel GSM BTS 18000 Fundamentals(411-9001-160)

• Each ICM receives a normal clock on the Abis lines, but double lineadaptation is provided. It is probable that both ICMs get a clock that isgood enough to lock their PLL on.

• Each ICM tries to transmit on the Abis lines, so there is some electricalcontention. There is no destruction risk but it is possible that corruptedmessages are seen at the level 2 layer on the OMC-R.

5.2.44 Replacing a cableThis general procedure can be used to replace the cables of the BTS18010 and BTS 18020. It is a general procedure and not specific to anyone type of cable. For more information, see the Table 49 "BTS 18010internal RF cables" (page 218).

Cables that are completely external to the BTS (for example, feeder cablesgoing up to the antenna, AC main power supply cables, etc.) are notdescribed in this document and this procedure does not apply to them.

The cables that can be replaced using this general cable replacementprocedure are listed in the tables below. The tables are organized by typeof cable (RF, digital, other) and whether they are internal (each end of thecable is connected inside the BTS 18000 cabinet) or external (one end isconnected outside the BTS 18000 cabinet). In these tables, a PEC markedby an asterisk * indicates the RoHS version.

While using the procedure, the user needs to have replacement cablesonly for the defective cables that are going to be replaced (the user do notneed to have all the cables listed in these tables).

Product reference (for BTS 18010)The following table lists the BTS 18010 internal RF cables that can bereplaced using this general cable replacement procedure (* indicates theRoHS version).

CAUTIONService interruptionThe impact on service depends on the cable concerned andits current state. If the cable is totally defective, removing it willnot affect the service (since the cable is no longer performingits intended function). If the cable is partially defective (forexample, due to an intermittent fault), removing it will stop itfrom performing its intended function even partially.


LocationThe exact location depends on the cable. See Figure 1 "BTS 18010 withBCF on IBP/CIBP (not supporting Abis over IP)" (page 17).

Procedure

Step Action

1 Identify the defective cable.

a Do a visual inspection.It is unusual for the cable itself to become defective except asa result of some external action (for example, the cable mayhave been cut accidently during a another maintenance orupgrade operation, or it may have been damaged deliberatelyin the case of access by some unauthorized person). In caseof defect, it is more likely to be the cable connector ratherthan the cable itself that is the cause. This is more likely tobe as a result of an external action rather than any normaloperation.

b If necessary, ask the OMC-R operator (who should be awareof any alarms or anomalies that can help identify the cableconcerned).

c In certain cases, TIL may be of help.

2 Check that the user has a replacement cable of the appropriatetype and length.

a The PEC of the replacement cable should be the same asthat of the defective cable.

b The replacement cable must be of sufficient length to give thesame reach as the defective cable. Since cables of different



.


lengths have different PECs, if the user verified the previouscondition, this condition should also be satisfied.

c If the user do not have an appropriate replacement cable,the user should abandon the procedure, and start from thebeginning once the appropriate replacement cable has beenobtained.

3 Tag the cable connector at each end of the defective cable. Theuser can do this using adhesive tape or an adhesive label. Thistag should show the exact position where the connector is fitted.An example of a cable with tags in shown in Figure 71 "Exampleof defective cable with tags near connectors" (page 233) .

a Start from either end of the defective cable.

b Write the exact module number (DDM0, RM, etc.) and theexact position (Tx0, Rx1, etc.) on the adhesive tag.

c Go to the other end of the defective cable (if necessary, usefingers to follow the cable to its other end).

d Write the exact module number (DDM0, RM, etc.) and theexact position (Tx0, Rx1, etc.) on the adhesive tag.

4 Inform the OMC-R operator that the cable is ready to bedisconnected.The OMC-R operator will take whatever action (if any) neededon the OMC-R and will inform the user when to proceed.

5 Disconnect the cable at each end.

a Start from either end of the defective cable.

b Disconnect the cable (the tool used depends on the type ofconnector).

c Repeat the previous operation for the other connector.

d Remove the cable (if the cable is tied to other cables withTy-wraps, cut the Ty-wraps).

6 Visually compare the replacement cable with the defective cable.

a The connectors on both cables should be of the same types.

b The cables should be of comparable length.

For the replacement of the CSU-RICAM cable, due to thedifference in cable lengths, make a loop in the cable abovethe digital rack. Tie the cable with straps.

7 Install the replacement cable.

a Ensure that the user installs the replacement cable at theexact same locations as the defective cable. If necessary,look at the tags that is attached to the defective cable at Step3.



.


b If the defective cable was tied to other cables with Ty-wraps,re-tie it with new Ty-wraps).

8 Inform the OMC-R operator that the cable has been replaced.The OMC-R operator will take whatever action (if any) neededon the OMC-R.

9 Dispose of the defective cables in accordance with thecompany’s policy for defective equipment. The user may removethe adhesive tags that was placed on the cable at Step 3.
