DDM-2000 OC-3 MULTIPLEXER
DO ITEMS BELOW IN ORDER LISTED . . . . .FOR DETAILS, GO TO
19.
NOTE:
If the OC-3 circuit pack is going to be using the same
cross-connects as the EC-1 circuit pack that is to be
removed, then the only cross-connects that need to be
deleted are those at the node where the circuit pack is being
replaced. The pass-through cross-connections can remain.
NTP-036Discontinue the EC-1 interface cross-connections at the OC-3
node associated with the FT-2000 primary node. Note that only
cross-connections at the DRI node are being discontinued
when using the procedures of NTP-036.
20. At the OC-3 node associated with the FT-2000 primary dual ring
interworking node, remove both BBG6 STS1E circuit packs from
function unit slots being upgraded to OLIUs (for example, node C
in Figure 2).
21. Momentarily depress UPD button on SYSCTL or use the upd
command from the CIT.
22. At the FT-2000 primary dual ring interworking node (for example,
node B in Figure 2), use FT-2000 procedures in 365-575-103,
FT-2000 OC-48 Lightwave System, Release 8.1 Through 9.1,
