Administration and Provisioning
8-18 Issue 8.0 July 2002
In Release 5 and later releases, a bridge cross-connection is any two
superimposed cross-connections sharing the same source. The source
can be any incoming STS-3 tributary of OC-48 high-speed line 1E or 1W,
or any service low-speed interface slot.
In Release 5 and later releases, cross-connections can be made to/from
any service low-speed interface slot and the companion low-speed
interface slot (for example, 2A and 2B) when the slot pair is provisioned for
the OC-3 1+1 protected mode. For example, Figure 8-3 shows incoming
service STS-3 tributary 6 of OC-48 high-speed line 1E cross-connected to
outgoing service STS-3 tributary 6 of OC-48 high-speed line 1W. Incoming
service STS-3 tributary 6 of OC-48 high-speed line 1W is also
cross-connected to service low-speed interface slots 8A and 8B.
