6. The physical DS3(EC-1) loopback can remain until service is applied. Ver-
ify that no ‘Inc. EC1 LOS’ alarms exist and continue testing the next chan-
nel.
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 22 Type 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 Node 1
(Shelf 1) OLIU Slot Main-1 (M1) must connect to Node 2 Slot Main-2 (M2). Node 2
OLIU M1 would connect to Node 3 OLIU M2 and this would continue (M1
