An example of the customer application in the mobile market is displayed in
Figure 13: MC-APS with ATM VLL Redundancy
In the application show in
, 2G and 3G cell sites are aggregated into a Tier 2 or Tier 3
hub site before being backhauled to a Tier 1 site where the radio network controller (RNC) which
terminates user calls is located. This application combines MC-APS on the RNC access side and
pseudowire redundancy and pseudowire switching on the core network side. pseudowire
switching is used in order to separate the routing domains between the access network and the core
network.
