different Aggregation Routers to provide protection against router failure. The MLPPP bundle
operates between the BTS and the Aggregation Routers. At any one time only one of the two
Aggregation Routers is actually terminating the MLPPP bundle (whichever Aggregation Router is
processing the active APS circuit).
This example illustrates the following:
•
MC-APS (the APS circuits terminate on different Aggregation Routers)
•
APS protecting MLPPP bundles (bundles are between the BTS and the Aggregation
Routers but APS operates on the Sonet links between the DACS and the Aggregation
Routers)
•
APS on channelized access interfaces (OC-3/OC-12 links)
