It is important that the pass-through signal is assigned the same channel address
for all nodes in the ring, including the add/drop nodes mb-1 in the example.
Do the following procedure:
1. Using the work order, identify the TIDs of the entry and exit points on the
ring (Nodes 1 and 5 in the example).
2. Determine if the work order is specifying use of a particular ring channel
(some work orders may abbreviate the mb designation as m1). If the work
order does not designate an STS-1 ring channel to use, use the rtrv-
crs-sts1:all; to identify all unused ring channels. The output report
will show only active cross-connections. In the example, we will cross-
connect a DS3 from Node 1 through the ring and drop the DS3 at Node 5
using mb-1.
3. Log in or remote log in to all the TIDs that are not entry and exit points
(intermediate nodes) and enter ring "pass-through" cross-connections. At
each intermediate node of the network, use the ent-crs-sts1:
command to cross-connect the DS3 channel time slots between main B-1
and main B-2. For example, to cross-connect the channel time slots
associated with STS-1 #1, use the ent-crs-sts1:mb-1,mb-1
command.
NOTE:
Address 1 and address 2 must be the same.
4. Log in or remote log in to each drop node and enter the "drop" cross-
connection. At both drop nodes of the DS3 circuit being established, use
the ent-crs-sts1: command to cross-connect the DS3 channel time
slot to the proper group, slot, and port; for example,
ent-crs-sts1:mb-1,a-1.
NOTE:
Only one command is required to establish the drop cross-
connections on both rings between main B and Fn-A. At exit nodes,
assuming normal operation, the same signal is present on both
rings. The system monitors the input from each ring and selects one
to drop to Fn-A.
