DO ITEMS BELOW IN ORDER LISTED. . . . . FOR DETAILS, GO TO
6.
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.
7.
Remove all EC-1/DS3 connections between the OC-3 and OC-12
nodes with 3STS1E/STS1E circuit packs removed.
8.
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.
9.
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.
10.
NOTE:
The section data communication channel (DCC), used for far
end communications, must be enabled at each network
element (shelf) for the end-to-end line tests to work when the
optical span is being established. Default condition for the
DCC channel is "enabled". If it has been disabled, use the
set-fecom:
command at each DDM-2000 shelf to enable
far end communications.
NOTE:
The network elements that terminate on each end of the
optical span must have their Network Side/User Side
parameters set to opposite values to avoid an
inconsistent DCC values
alarm. One end is
provisioned as "Network Side" and the other end is
provisioned as "User Side". Both ends of the OC-3 line
cannot be the same and it makes no difference which end is
"Network Side".
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.
11. Perform optical fiber connections and verification of the optical
facility.
