CAUTION:
DDM-2000 circuit packs contain static sensitive components
which can be damaged by electrostatic discharge. A static
ground wrist strap must be worn when handling the circuit
packs. See electrostatic discharge considerations in Trouble
Clearing: TAD-100 .
NOTE:
This procedure requires 21G/21G-U/21G2-U/21G3-U OLIUs
(OC-3) or 21D/21D-U OLIUs (IS-3) circuit packs in all
DDM-2000 OC-12 shelves and
22G-U/22G2-U/22G3-U/22G4-U OLIUs (OC-3) or 22D-U
OLIUs (IS-3) circuit packs in all DDM-2000 OC-3 shelves.
Existing 3STS1E and STS1E circuit packs will be replaced in
this procedure with OLIU circuit packs to support OC-3/IS-3
applications. Optical line power measurements and/or office
records must be used to verify that the span length can be
supported.
NOTE:
This procedure assumes that the DDM-2000 systems are in
service. Ring TARP Release 7 or later software is required in
each DDM-2000 OC-12 shelf. Ring TARP Release 13 or
later software is required in each DDM-2000 OC-3 shelf.
NOTE:
All shelves in the same network must have the same or
compatible software releases.
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
