[cisco-nas] AS5400 More than 256 HDLC channels per CT3 card

[Aaron Leonard]

Joe, the 256 HDLC framers are on each CT3 card, and you can't use the 
framers on one card to handle channels on another card. However, you can 
go past the HDLC channel limit by adding NextPort DSPs to handle the 
HDLC framing ("Tardis"), and then the DSPs do act as a global pool.

Afaik, we never documented anything on this on CCO.  Below is a snippet 
of a config that uses RPM to switch HDLC calls to a "Tardis" DSP pool.

Hth,

Aaron

Yes, you can use RPM to route your HDLC calls to NP resources. Basically
you create a DNIS based customer profile and specify NP resource range for
that number, such that the call will be routed to NP resources instead of
default FreeDM resources. We use that in our Tardis testing and regression.
Here is the configuration looks like. If you need some automated help then
we have a ready-to-go scripts running for both AS5400 and AS5850.
