NOTE:
If the OC-3 ring is to be line timed (no external timing
available) from another system or ring,
BBF2B/BBF2C/BBF4 TGS/TG3 timing circuit packs must
be installed in the node connected to the other system and
the FUNCTION UNITS C slot must be equipped first to
provide a source of synchronization. See the set-sync:
command in the Commands and Reports section of this
manual.
Consult office records or work/circuit orders to determine the
OLIU function slots in each DRI node that will be used to connect
the two systems together in a DRI configuration. See Figure 1.
2.
NOTE:
If work order or office records do not specify OLIU types,
refer to 363-206-200, DDM-2000 OC-3 and OC-12

and/or 363-206-285, DDM-2000 OC-3 Multiplexer, TARP
Release 13 and Later, User/Service Manual—Volume I , for a
description of OLIU circuit packs and applications. Optical

used to verify that the span length can be supported.
At the DDM-2000 OC-3 dual ring interworking nodes, install OLIU
circuit packs in selected FUNCTION UNIT slots.
3. If FT-2000 shelves are the dual ring interworking nodes, use

System, Release 8.1 Through 9.1, User/Service Manual , to Add
OC-3/IS-3 Low Speed Circuit Pack(s), NTP-010. If DDM-2000
OC-12 shelves are the dual ring interworking nodes, use
