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 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
connecting to M2) around the ring until all nodes in the ring are reached. Refer to
Figure 8-1.
1. Set each shelf in the system for the correct timing. Conventionally, one
node in the ring will be set for either free running or externally timed and
the others will be looped timed. Only one node may be free running. More
than one node can be externally timed if traceable to the same source
clock, and the remainder looped. Check that external connections are com-
pleted if option is set for external.
2. If TGS Circuit Pack option switch is changed, an update must be done by
momentarily depressing the UPD/INIT button on the SYSCTL after the
TGS pack is installed.
3. Issue the set-ne command to provision each shelf for the following
parameters:
a. Each shelf must have a unique TID (Target Identifier).
b. One shelf (and only one shelf) in the network must be set as the
DSNE (Directory Services Network Element).
c. The Alarm Group must be the same (default=255) for each shelf for
complete alarm reporting throughout the network.
d. One shelf in the network (preferably not the shelf that’s set as the
DSNE) must be set as the AGNE.
e. Site ID and NE (Network Element) combinations must be unique in
each shelf.
f. Shelf numbers must be unique when shelves are located within the
same bay.
