All TRX are in BL-RSL state

Solution:

Tested circuit with telco and found that the T1 has a loop left out.

Tech from telco normalized T1.

All TRX came to WO state one by one.

Conclusion:

This is is a working T1 circuit and was rewired on the demarc and probably the Tech called for testing and

the loop was left up. Before touching the circuit path let telco test their side first before isolating the T1

towards you. This will prevent tampering existing and working path.

I got an alarm on the BSC 2205 ET2 Failure

COMMAND EXECUTED

CIRCUIT STATE HANDLING COMMAND

Check the transmission between (the BTS) the BSC and transcoder.

Check other active alarms concerning (the BTS) the BSC and transcoder transmission or transcoder plug-in

units.

Correct the faults causing the alarms. When the above-mentioned transmission alarms have been

cancelled or when transmission is working again, deblock the circuit in question with the MML command

CEC.


4/19

This alarm only informs the user that calls are cleared due to unsatisfactory transmission or equipment

failure but it does not directly indicate the faulty equipment, for example a plug-in unit.

Cancelling:

Do not cancel the alarm. The system cancels the alarm when the user blocks the circuit.

The system also cancels the alarm if a call is cleared in the circuit in question for some other reason than

BTS and transcoder unsynchronisation.

he command calendar is a program entity which is used to execute the MML

commands and command files at a given time or on the basis of alarms.

Set the backup procedure permanently into the command calendar. Activate the command calendar.

The command calendar can handle only one task at a time. If a task execution should start when the

previous one is still on, it is set to pending and the execution is delayed.

There are three modes for making a fallback:

1. FULL creates a new fallback build

2. DATA makes a safecopy of data files

3. ARCHIVE makes a safecopy of changed files

Steps

1. Define the command into the command calendar (ICI).

ZICI:,::;

After the ICI command execution, the necessary parameters for the given

MML command are requested.

:MODE=,DIRE=,

NAME=;

Example 1. Data type

ZICI:WKS,::TIME=01-00,PTYPE=DA,PNBR=1,NBR=255;

The parameters for the command WKS are requested:

MODE=DATA;

The command calendar makes a safecopy of the data files every night at 01:00 a.

m.

Example 2. Archive type



MODE=ARCHIVE;

The command calendar makes a safecopy of the changed files every night at 01:00 a.m.


5/19

Example 3. Full type

If the command calendar is used for making a fallback of the entire software build, do not define an

existing file or directory name for the FB build in the command. If you want to use an existing name,

delete it from the Winchester disk before executing the command.

In the following example, the delete command of the existing fallback is added to the calendar before the

actual fallback command and a sufficient amount of time is reserved for the deleting operation. The

command calendar deletes the existing

fallback build every night at 01:00 a.m. and makes a safecopy of the entire software build every night at

02:00 a.m.

Deleting the existing fallback:

ZICI:WQD,::TIME=01-00,PTYPE=DA,PNBR=1,NBR=255;


DIRE=:MAFILE,::;Making a new fallback:



MODE=FULL,DIRE=,NAME=;

2. Test the task execution of the command calendar (ICT).

ZICT;

Further information:

With the ZICL command you can list the command calendar tasks.

3. Check that the fallback is successfully completed by displaying the log file of the fallback (WKP).

ZWKP::;

Expected outcome

The fallback is successfully completed when no errors occur during the procedure.

Unexpected outcome

If there are errors, you must do the fallback again.

Check the usability of the copy in the supplementary information field of the alarm.

For more information, see Expected/unexpected results.

4. Check the states of the databases (DBS).


6/19

The states of the databases BSDATA and OEDATA should be normal or dumping. The state of the database

EQUIPM in the spare unit should be abnormal.

Further information:

You can delete a command calendar task with the ICD command.

If the daughter board is missing, install it.

Cancelling:

Do not cancel the alarm. The system cancels the alarm automatically when the fault has been corrected.

The SIBs provide the switching function to the destination FPC (see Figure 1). The SIBs create the switch

fabric for the router, providing up to a total of 320 million packets per second (320 Mpps) of forwarding.

Three SIBs are installed in the router. The SIBs are located at the center rear of the chassis in the slots

labeled SIB0 through SIB2.

SIBs are hot-insertable and hot-removable.

The wrist strap is connected to ground through a coiled retractable cable and 1megaohmresistor,which

allows high-voltage charges to leak through but prevents a shock hazard when working with low-voltage

parts. Where higher voltages are present, extra resistance (0.75megaohmper 250 V) is added in the path

to ground to protect the wearer from excessive currents; this typically takes the form of a 4 megohm

resistor in the coiled cable (or, more usually, a 2 megohm resistor at each end). Very cheap wrist straps do

not have conductive fabric and instead use the fabric to hold the metal plate against the skin, which can

result in reduced ESD protection over time as the metalcorrodes.

Wrist straps in industry usually connect to Earth Bonding Points (part of the grounding system) via either a

4 mm plug or 10 mm press stud, whereas personally owned straps are likely to be connected to ground

via acrocodile clip.

In addition to wrist straps, ankle and heel straps are used in industry to bleed away

accumulated charge from a body. These devices are usually not tethered to earth

ground, but instead incorporate high resistance in their construction, and work by

dissipating electrical charge to special floor tiles. Such straps are used when

workers need to be mobile in a work area and a grounding cable would get in the

way, such as in anoperating theatre.

If working on pinball machines, these items are classed as useless due to the

current being unable to dissipate in time. The recommended product for this is "LHIP" (as it is known in

the industry) or Left Hand In Pocket.

Wireless or Dissipative wrist straps are available, but they are widely considered aspseudoscientifichoax

products. The claims of the operating principles vary from "Ion Neutralization, Skin Effect, Point Discharge

and Corona Discharge Effect" to "Selglard electric halo principles".[1][2]

verview of BSC i commissioning

These instructions are intended to be used in the commissioning of the system in the final location of the

BSC3i. They can be used with the ANSI or ETSI environment BSC3i 1000/2000 variants. (For information on

the commissioning of BSC3i 660, see Commissioning BSC3i in Nokia BSC/TCSM S11.5 Product

Documentation.)

Prerequisites for the successful commissioning according to these instructions are that:

the BSC has passed the factory acceptance tests

the installation has to be accepted

at least the files associated with the configuration are ready on thehard disks of the BSC

the site has been built and prepared according to Nokia BSC Base

Station Controller, Rel. S12, Site Documentation for BSC3i

in a two-cabinet configuration, the cabling has been done during the

installation phase

All the software that belongs to the BSC must be ready on the hard disks of the system before starting the

commissioning tests. If there is newer SW available than what is installed in the BSC disk, the BSC must be

commissioned with the same SW that is installed on the disks. The newer SW is installed before the

integration of the BSC.

In the final BSC site the tests which, according to the test logs delivered with the hardware, have already

been performed at the test field of Nokia Corporation, do not necessarily have to be performed.

The purpose of the commissioning tests is to ensure that the BSC will operate correctly in the GSM

network. When the commissioning tests have been performed in an acceptable manner, the BSC can be

taken into


15/19

traffic. Depending on the configuration, the commissioning of BSC3i 1000/2000 takes around 3-5

working days.

CMM replace procedure

a) Ensure all cables connected to the CMM are properly labeled before disconnecting.

b) Press and hold the reset button (Alarm Cutoff Pushbutton) on the standby CMM until blue hot swap

light comes on momentarily (see figure below), disconnect cables, unlatch the card and then extract the

card from the chassis.

c) Insert the replacement CMM in the chassis and re-connect the cables.

d) Wait for the CMM to boot up and be ready.
