NOTE:
The section data communication channel (DCC), used for
far-end communications, must be enabled at each network
element (shelf) for communication and to allow the
end-to-end line tests to work when the optical span is
established. Default condition in DDM-2000 is "enabled" for
the DCC channel. If it has been disabled, use the
set-fecom: command at the DDM-2000 shelf to enable
far-end communications.
At the 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.
8. At each DDM-2000 OC-3/OC-12 node, use the
set-oc3/oc12:address:syncmsg=Kbyte/Sbyte command
to enable sync messaging between the DDM-2000 FUNCTION
UNITS OLIUs connecting to the other ring DRI nodes.
9. At each DDM-2000 OC-3/OC-12 DRI node, use the
set-oc3/oc12:address:syncmsg=disabled command to
disable sync messaging between the DDM-2000 MAIN OLIUs
connecting the adjacent DRI nodes of the DDM-2000
OC-3/OC-12 ring. For example in the top DDM-2000 OC-3 ring in
Figure 1, disable sync messaging between CO 2 MAIN 1 and
CO 4 MAIN 2(P).
10. At FT-2000 DRI nodes, if only one Optical Interface is used for the
DRI connection, use CONFIGURATION-Set-OC3 command to
set the protection mode to 0X1for the OC-3 slot used for DRI
connections. If two Optical Interfaces are used for the DRI
connection, use CONFIGURATION-Set-OC3 command to set the
protection mode to 1 + 1 for the OC-3 slot used for DRI
connections.
11. At FT-2000 DRI nodes, use
CONFIGURATION-Enter-Assignment-DCC command to
assign a DCC channel to slot(s) used for DRI connections.
