Alarm Muting

Step Operation

1 Check the MUTE switch on the cabinet, which shall be ON

normally. Set the switch to OFF and the alarm sound stops.

2 Check the ALC switch on SCC, which shall be ON normally.

After confirming an alarm, set the switch to OFF and the alarm

sound stops.

3 If alarms are connected externally to the centralized alarming

system, check if the switches and connection cables on the

centralized alarm system are normal.

Cleaning Fan Filter

Step Operation

1 Check whether there is FAN_FAIL

alarm on NM.

2 Check the running of six fans. The

six green indicators are on and the

red indicator is off when therunning is normal.

Step Operation

1 Draw out the air filter by the handle. Take the air

filter outdoors and wash it, then mop it and have

it blown to dry at a place with good ventilation.

2 After cleanup, insert the air filter back. Align the

air filter to the guide rail on the lower part of the

subrack, and push it in gently.

Using Orderwire Phone

Step Operation

1 When the orderwire phone rings, with thered indicator at back flashing, it indicates

there is an incoming call.

2 Off-hook the phone, press button TALK

and then the red indicator on upper right

is on, and the call is through

Step Operation

1 Set the ring switch of telephone to ON

2 Set the dial mode switch to T and select

dual-tone dialing

Step Operation

1 Off-hook the phone, press TALK on the

face and then the red indicator on upper

right is on, accompanied by dialing tone.

2 Dial the orderwire number of other NEs

Analyzing and Testing Optical Spectrum

Step Operation

1 Connect the board at MPI-S/MPI-R with a spectrum

analyzer.

2 Set the spectrum analyzer to the WDM test mode.

3 Test the indices of each channel of signal and record the

result.

4 Compare the result with history or standard data, and

then analyze the exceptional data.

Plugging/Unplugging Patch Cord

Four kinds of optical interfaces:

SC/PC,LC/PC,FC/PC,E2000/APC

Plug/unplug SC/PC: use special tool

(such as fiber extractor)

Plug/unplug LC/PC: in the axial direction

without rotation

Make sure the board to be replaced and the replacement

board are the same board type, especial for OTU cards.

For example: SSE1OAU01

Replacing SCC/SCE board

Replacing Card

On SCC/SCE, there are NE ID, nesoft, configuration data, so pay

special attention:

Before replacement, configure the ID

After replacement, resend the configuration data to NE from NMS


13/27


Before replacement

During replacement

After replacement

Check board version

(Especially for OTU)

Detailed information can be

obtained from the bar code.

Skilled at the operation methods in

General precautions.

The setting of board jumpers and DIP

switches;

Input optical power range of optical

interface board;

Remove the optical fiber from the frontpanel;

Width of the front panel.

Wear an ESD wrist strap. Correctly

swap the board. Avoid short-circuit

of the board.

Prevent eyes from being hurt by the

laser.

Check whether the board

is working normally, and

upload configuration on

the NM again.

If you replace the SCC board, you should

upload the original SCC configuration data

to the NM, and then download them from

the NM to the new SCC.

Pay attention to NE user configuration.

Classification ofboards

Board name Remarks

Opticaltransponder unit

OTU For new OTU:a. The type is identical with the original one.

b. The wavelength, optical module is identical with that of theoriginal one.

Optical amplifierunit

OA a. Prevent the over-high input optical power from damaging opticalcomponents.

b. Keep the operating band of the new optical amplifier unitidentical with that of the original one.

c. Do not stare into the output optical interface, since the outputoptical power of OA is very high.

Opticalmultiplexing/demultiplexing &

add/dropmultiplexing unit

MUX/DEMUX

a. Prevent the over-high input optical power from damaging opticalcomponents.

b. Keep the operating band of the new optical amplifier unit

identical with that of the original one.c. Keep the type of the substitute board identical with that of theoriginal one.

Bit Error Test

Step Operation

1 Set the BER tester and connect it to perform the BER test.

Multiple OTU (Optical Transponder Unit) boards can be cascaded

for BER test. The dot line may represent multiple OTUs (including

the OTU of the opposite end), or the optical path consisting of the

multiplexer unit, demultiplexing unit and the amplifier unit.2 Start 24h BER test, the error should be 0 normally.

3 If any bit error occurs within 24 hours, locating the fault by

analyzing the B1 value of the OTU through the NM. Conduct the

test again after the fault is removed.
