primarily VT1.5 based and is accessed from any one of the 12 STS-1s. OC-12
and OC-3 multiplexers equipped with OC-12 optics can be mixed in the same
OC-12 ring. The OC-12 multiplexers can be used at sites requiring DS3 and other
higher bandwidth STS path-switched traffic, while the FiberReach multiplexer is
used at sites requiring VT path access for DS1, T1, etc. Figure 2-7 shows an OC-
12 ring that includes both OC-3, OC-12, and FiberReach multiplexers.
