end.

In the MGX-RPM-1FE-CP backcard configuration example, only the keepalive interface command and 
configuration recommendation is specific to implementation in an IP RAN solution.

This new feature is identified by CSCdy78207.

The following new features are introduced in Cisco IOS Release 12.2(8)MC2c:

The MGX-RPM-1FE-CP now supports up to 16 multilink interfaces.

The additional interface support requires that the number of RTP compression-connections for an 
interface be managed using the ip rtp compression-connections command.

Up to 6000 compression-connections can be allocated with up to 1000 RTP compression-connections 
per multilink interface. If more than 6000 compression-connections are configured, an error message 
similar to the following will display whenever an interface comes up and it does not receive all of its 
requested compression-connections:

00:22:32:%IXP1200_CP-1-HPRX_CTX_MEM_POOL:Out of resources for Multilink5. Requested 1000 

compression-connections, Obtained 900.

While an interface that does not obtain enough compression-connections will still function, the 
compression will be limited to the number of connections that it did obtain. If no 
compression-connections were obtained, all packets will be sent decompressed.
