Upgrade DDM-2000 OC-3 Ring Network With
FiberReach OC-3 Shelves to OC-12 Ring Network
In Service
DO ITEMS BELOW IN ORDER LISTED . . . . FOR DETAILS, GO TO
1.
!
CAUTION:
Alarms created due to removal of 28-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 28-Type OLIUs to an OC-12
path protected ring network using 29-Type OLIUs in
DDM-2000 OC-3 and FiberReach shelves. 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 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:
FiberReach TARP Release 4 software must be installed in
FiberReach OC-3 shelves.
