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).
displays an example of MLPPP termination on APS protected channelized OC-n/STM-n
links. This example illustrates the following:
•
SC-APS (the APS circuits terminate on the same node Aggregation Router 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)
•
APS on channelized access interfaces (OC-3/OC-12 links)
Figure 12: SC-APS MLPPP on Channelized Access Interfaces Example
depicts an APS group between a digital access cross-connect system (DACS) and a pair
of Aggregation Routers. At one end of the APS group both circuits (OC-3/STM-1 and/or OC-12/
STM-4 links) are terminated on the DACS and at the other end each circuit is terminated on a
