Procedure for Removing Cross-Connects
After all function groups are tested and verified as functioning properly, the cross-
connect map needs to be deleted. There are two ways to delete cross-connects;
choose the appropriate method.
1. To delete DS1 cross-connects issue the command:
dlt-crs-vt1:m-1-all,a-all:y
;
Replace ‘m-1-all,a-all’ with the address to be deleted.
2. To delete DS3/EC-1 cross-connects, issue the command:
dlt-crs-sts1:m-1,a:y
;
Replace ‘m-1,a’ with the address to be deleted.
NOTE
:
If cross-connects remain, VT AIS alarms will remain until cross-connects
are entered for all remaining shelves in the ring.
3. To delete all cross-connects, an initialize system command is used.
The
init-sys
command is a privileged user command and thus the
appropriate login is necessary. Refer to the ‘Login Procedure’ Section ear-
lier in this section. Issue the command
init-sys:all
;.
!
CAUTION:
Remember that the init-sys:all command should be used with extreme cau-
tion in an in-service system as it deletes all cross-connects.
Remove the fiber loopbacks from the OLIU circuit packs. Incoming OC-3 LOS
alarms will exist for main-1 and main-2 OLIUs. Incoming VT AIS alarms will exist
for remaining cross-connects.
Fiber Installation and Test
Description
The following procedure describes fiber connection and test. To achieve
transmission in both directions for a two fiber ring, fibers originating at the first
shelf (Shelf 1) OLIU Slot Main-1 (M1) must connect to the second shelf Slot
Main-2 (M2). The second shelf OLIU M1 would connect to the third shelf OLIU M2
and this would continue (M1 connecting to M2) around the ring until all shelves in
the ring are connected. Refer to Figure 9-1.
