Entering 1-Way-DRI Cross-Connections in Video Applications 8
Figure 8-21 shows a 1-way circuit that has been established on a 2-fiber
bidirectional ring that is part of a 1-way video application. The 2-fiber bidirectional
ring has two nodes with 1-way-DRI cross-connections (node 0 and node 2) and
each node has a 1-way drop cross-connection from line 1W. Nodes 1, 3, and 4
also have a 1-way through cross-connection.
Figure 8-21. Example of 1-Way and 1-Way-DRI Cross-Connections in
Video Applications
The CONFIGURATION-Enter-Crossconnection-STS3 input is used to enter
1-way and 1-way-DRI cross-connections at the nodes. (Refer to "Entering 1-Way
and 2-Way Cross-Connections" in this section for examples showing bridge and
2-way cross-connections.)
