Figure 8-7. Limited STS-1 Cross-Connections Across and STS-3
Tributary
A 1-way drop and a 1-way add cross-connection are entered at the FT-2000
OC-48 Add/Drop-Rings Terminal in Figure 8-7. A 1-way drop cross-connection is
made from incoming service STS-3 tributary 6 of OC-48 high speed line 1E to
service low speed interface slot 6B. A 1-way add cross-connection is made from
service low speed interface slot 2A to outgoing service STS-3 tributary 6 of OC-48
high speed line 1W. The individual STS-1 tributaries (DS3 signals) from the DS3
circuit pack in low speed interface slot 8B are looped back (through cabled) at the
DSX-3 cross-connect panel (or equivalent) to the DS3 circuit pack in low speed
interface slot 2A.
