No, modem connections do not use up an HDLC channel - only sync port
connections
do, like ISDN-PPP, Frame-Relay, ISDN-MP etc.

Since the MAX40xx can have up to 4*30 (Europe) channels = 120, and the base
unit
has 64 channels "built in", you might need to add more 32HDLC cards to support
more than 64 simultaneous HDLC sessions (1 frame-relay port T1/E1 can use
up 24/30
in one go)....

No, that's not true - as I suggest above.
