24-Type OLIUs to OC-12 Ring Network

1.
CAUTION:
Alarms created due to removal of 24-Type OLIUs are
non-service affecting, except those related to STS3c 0X1
cross-connected channels which are service affecting.
NOTE:
This procedure is used to convert an OC-12 VT1.5 path
protected ring network using 24-Type OLIUs to an OC-12
path protected ring network using 29-Type OLIUs in
DDM-2000 OC-3 shelves only. If an OC-12 shelf is being
added to the ring fibers to support single-homing the original
OC-3 shelf at the CO, use the procedures of NTP-024
instead of this procedure.
NOTE:
This procedure uses a 4-node OC-12 ring as an example for
the OC-12 OLIU ring upgrade (Figure 1). This upgrade starts
at Node 1 and proceeds clockwise. Local procedures will
have to be written, using the concepts of this procedure, to
upgrade the particular configuration that you have.
NOTE:
As this is not a network upgrade, there is no required
sequence of upgrading nodes around the ring. The following
procedure can be performed at any node with 24-Type
OLIUs.
NOTE:
This upgrade cannot be initiated from the MAIN 2(P) slot.
NOTE:
OC-3 TARP Release 15 software must be installed in OC-3
shelves.
