Entering 1-Way-DRI STS-3 Cross-Connections in Dual Ring Interworking
Applications 8
Figure 8-20 shows a 1-way circuit that has been established on a 2-fiber
bidirectional ring that is part of a dual ring interworking application. 1-way and
1-way-DRI cross-connections are used at the primary and secondary nodes. The
CONFIGURATION-Enter-Crossconnection-STS3 input is used to enter
1-way and 1-way-DRI cross-connections. Refer to "Entering 1-Way and 2-Way
Cross-Connections" in this section for examples showing bridge and 2-way
cross-connections.
