9. At the terminating (drop) nodes of the circuit being established, use the
ent-crs-vt1: or ent-crs-sts1: command to make the terminating
cross-connections (for example,
ent-crs-vt1:m-1-2-3,a-2-3:cct=twoway)or
ent-crs-sts1:m-1,b:cct=twoway)
10. From work order or circuit order, determine the dual ring interworking node
sites where the two rings are being interconnected.
11. From work order or circuit order at each dual ring interworking node, determine
the "drop and continue" cross-connections to be made at each node.
12. At the dual ring interworking node sites, make or verify proper backplane EC-1
cable connections [J38-J39 (FUNCTION UNITS A), J40-J41 (FUNCTION
UNITS B), J42-J43 (FUNCTION UNITS C)] between FUNCTION UNITS
groups used for service being provided. See CO 1 and CO 2 in Figure 5.
13.
NOTE:
Ring 1 is the ring being received on the MAIN 1 OLIU. Ring 2 is the ring
being received on the MAIN 2(P) OLIU.Thering parameter of the
ent-crs commands is used to identify which ring rotation will be
continued as well as dropped at a node. For example, if Ring 2 continues
to the next node, then ring=m2
At the dual ring interworking node sites, determine the ring (Ring 1 or Ring 2)
rotation that will be continued to each node. For example, in Figure 5, note that
at CO 1 in the top ring configuration, Ring 2 is continued to CO 2. In the bottom
ring configuration, Ring 1 is continued from CO 1 to CO 2.
14.
NOTE:
If VT1.5 cross-connections in the same STS-1 are made at a dual ring
interworking node site, all VT1.5 "drop and continue" cross-connections
at that node must be made in the same direction.
At the dual ring interworking node sites, make proper "drop and continue"
cross-connections. For example, at the top node at CO 1 if STS-1 #1inMAIN
OLIU (m-1) is to be cross-connected to function group B (b) then the
command ent-crs-sts1:m-1,b:cct=dc,ring=m2 wouldbeusedto
make the cross-connection. This command makes both the drop
cross-connection as well as the continue cross-connection. If FT-2000 is a part
of the DRI configuration, use 365-575-103,
FT-2000 OC-48 Lightwave System,
Release 8.1 Through 9.1, User/Service Manual
, to make FT-2000 DRI
cross-connections.
