Provisioning now as a VT1.5 cross-connect will avoid a hit on traffic if
the STS-1 cross-connect has to be converted to 28 VT1.5 cross-
connects (cnvt-crs)todropDS1satalatertime.
c. On STS-1 path-switched rings, all nodes in the ring must be
provisioned as STS-1 cross-connections.
To do a cross-connection successfully, proper addressing of cross-connect points is
necessary. Figure 8-2 shows example STS-1 addresses. For a complete list of
valid addresses, refer to Table 8-5 through Table 8-17.
