Upgrade DDM-2000 OC-3 Ring Network to
OC-12 Ring Network Using OC-3 Shelves
DO ITEMS BELOW IN ORDER LISTED. . . . . FOR DETAILS, GO TO
1. !
CAUTION:
Alarms created due to removal of 22-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-3 VT1.5 path
protected ring network using 22-Type OLIUs to an OC-12
path protected ring network using 24/29-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. It is assumed that the fiber being
used in the current OC-3 ring network will be used to build
the new OC-12 ring.
NOTE:
This procedure uses a 4-node OC-3 ring as an example for
the OC-3 optics to OC-12 optics ring upgrade (Figure ). 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:
OC-3 TARP Release 13 or later software must be installed in
OC-3 shelves.
