DO ITEMS BELOW IN ORDER LISTED. . . . . FOR DETAILS, GO TO
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.
Discontinue the EC-1 interface cross-connections at the OC-3
node associated with the FT-2000 secondary node. Note that
only cross-connections at the DRI node are being
discontinued when using the procedures of NTP-036.
5. At the OC-3 node associated with the FT-2000 secondary dual
ring interworking node, remove BBG6 STS1E circuit pack(s) from
function unit slot(s) being upgraded to OLIUs (for example, node
D in Figure 1).
6. Momentarily depress UPD button on SYSCTL or use the upd
command from the CIT.
7. At the FT-2000 secondary dual ring interworking node (for
example, node A in Figure 1), use FT-2000 procedures in
365-575-103, FT-2000 OC-48 Lightwave System, Release 8.1
Through 9.1, User/Service Manual , Delete DS3 and/or EC1 Low
Speed Port(s), NTP-003
.
8. At the FT-2000 secondary dual ring interworking node, use
FT-2000 procedures in 365-575-103, FT-2000 OC-48 Lightwave
System, Release 8.1 Through 9.1, User/Service Manual , Add
OC-3/IS-3 Low Speed Circuit Pack(s), NTP-010.
9. Install required OLIU(s) in the OC-3 node associated with the
FT-2000 secondary node (for example, node D in Figure 1).
