Upgrade DDM-2000 OC-3 Ring Network to
OC-12 Ring Network Using OC-3/OC-12 Shelves
DO ITEMS BELOW IN ORDER LISTED. . . . . FOR DETAILS, GO TO
1.
NOTE:
This procedure is used to convert an OC-3 VT1.5 path
protected ring network to an OC-12 path protected ring
network using 24/29-Type OLIUs in DDM-2000 OC-3
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 procedure also adds an OC-12 shelf at the CO and
single-homes the existing OC-3 shelf to the OC-12 shelf. If
only the OC-3 optics are being upgraded to OC-12 optics,
use the procedures of NTP-023. This upgrade starts at the
Node adjacent to the CO connected to MAIN 2(P) of the
existing CO OC-3 shelf 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:
You may also contact Lucent Technologies to provide this
in-service upgrade. Experienced Lucent Technologies
installers will help you plan and execute the network
upgrade. For more information, contact your Lucent
Technologies Account Representative.
Use the rtrv-alm: command at the OC-3 ring to verify that no
alarms, locks, or switches are present.
