Sample APS Applications
The following sections provide sample APS application examples.
Sample APS Application:
MLPPP with SC-APS and MC-APS on Channelized Interfaces
7750 and 7710 service routers support APS on channelized interfaces. This allows Alcatel-
Lucent's service routers to be deployed as the radio access network (RAN) aggregation router
which connects the base transceiver station (BTS) and the radio network controller (RNC).

STM-4 links) are terminated on the DACS and at the other end each circuit is terminated on a

APS protecting MLPPP bundles (bundles are between the BTS and aggregation router A,
but APS operates on the SONET links between the DACS and the aggregation router).
