Another configuration of the OC-1 hub network uses the full capacity of the OC-3
shelf by dropping up to 28 VT1.5 channels to the low-speed DS1 slots for each of
the 3 OC-1 ring extensions. The total capacity is 84 DS1 signals. This triple OC-1
Multiplexer configuration, shown in Figure 2-12, supports three independent OC-
1/DS1 ring networks with a consolidated host node for operations access, network
synchronization, and efficient physical packaging.
