12. Perform end-to-end OC-3/IS-3 line test at DRI nodes (For
example, between nodes D and G in Figure 1).
13. At the upgraded DRI nodes, use the ent-crs-sts1: or
ent-crs-vt1: commands to make proper "drop and continue"
cross-connections.
14. At the next set of dual ring interworking nodes having circuit packs
replaced, discontinue the EC-1 interface cross-connections at the
OC-3 node [NTP-036]/OC-12 node [NTP-025]. Note that only
cross-connections at the DRI node are being discontinued
using NTP-036 or NTP-025.
15. At the dual ring interworking nodes having circuit packs replaced,
remove both 3STS1E circuit packs from the OC-12 node and both
STS1E circuit packs from the OC-3 node. (For example, see
Figure 1. Remove the 3STS1E circuit packs from the OC-12 at
node C and the STS1E circuit packs from the OC-3 at node H.)
16. At both OC-12 and OC-3 nodes, momentarily depress the
UPD/INIT pushbutton on the SYSCTL or use the upd command
to update the DDM-2000 internal equipment list.
17. Remove all EC-1/DS3 connections between the OC-3 and OC-12
nodes with 3STS1E/STS1E circuit packs removed.
18. If 21G/21G-U OLIUs are installed in OC-12 node, set the option
switch on the 21G/21G-U OLIUs to agree with the loss of the
optical facility.
19. Install both 21G/21G-U/21G2-U/21G3-U OLIUs (OC-3) or
21D/21D-U OLIUs (IS-3) in the OC-12 node and both
22G-U/22G2-U/22G3-U/22G4-U OLIUs (OC-3) or 22D-U OLIUs
(IS-3) in the OC-3 node.
20. At each DDM-2000 shelf, use the
set-fecom:address:com=enabled,nsus=ns/us command
to enable far-end communications (fecom) and set Network Side
(ns)/User Side (us) parameters.
