This is useful information, but does it allow me to add more HDLC channels to a channel-group in a controller config? The problem I am having is that we add ds1 channels to ds3’s on an AS5400, add channel-gorups and pri-groups to the ds1’s, like so...
controller T1 1/0:26
framing esf
channel-group 0 timeslots 1-15 speed 64
loopback network ignore
pri-group timeslots 16-24
description combo PRI/T1
... and when channel-groups equal to 256 hdlc channels for the particular ds3 card have been added then the following happens....
AS5400#config t
Enter configuration commands, one per line. End with CNTL/Z.
AS5400(config)#controller t1 7/0:14
AS5400#(config-controller)#channel-group 0 timeslots 1-22 speed 64
%Insufficient HDLC resources to create channel group
So what I specifically need is to be able to add more channel-group timeslots to the ds1’s on the unit. If I add resource pools as shown in your example below, will it allow me to add more channel-groups and channels to a t1 controller config?

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,

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.

resource-pool enable
resource-pool group resource tardis-ports
range 1/0 - 1/323
resource-pool profile customer tardis-cust
limit base-size all
limit overflow-size 0
resource tardis-ports digital
dnis group tardis-dnis
dialer dnis group tardis-dnis
number <... your DNIS number here...>

The standard CT3 card for an AS5400 only allows 256 HDLC channels, or about 10.5 T1’s. Is there any other T3 card available for an AS5400 that supports more HDLC channels, or any way to increase the number of HDLC channels supported? Also, if I have two CT3 cards in a unit, are the HDLC channels for each tied to their respective cards, or are they available system-wide? That is, would two cards required that I set up 10 T1’s on each card, or would they allow me to set up 20 T1’s on one card and no T1’s on the other?
