Ring Drop and Continue Cross-Connection
Provisioning 8
All the information on "Ring Cross-Connection Provisioning" applies to "Ring Drop
and Continue Cross-Connection Provisioning." Please review "Ring Cross-
Connection Provisioning" as that information is not repeated here. Only the new
provisioning information is presented here. This information applies to STS-1
traffic. Only the cross-connection addresses are different.
Two nodes are defined to be drop and continue nodes in a ring subnetwork and
are the exit points where "two" copies of the same service are available. By
making two copies of the same service available at two nodes, the network is
protected from failure of a node (for example, a CO) that affects all traffic on the
ring. For rings that carry drop and continue services, the drop and continue nodes
should be neighbors (no intermediate nodes), and all "drop and continue" traffic
must be continued on the ring connecting the two nodes. If the two nodes are not
"neighbors," special procedures are required at the intermediate node. See the
TOP section of this manual (Volume II).
