There are 2 models. PM3-1T or 2T. You guessed it. The 1T can handle one
T1/CT1/PRI the 2T accomodates two T1/CT1/PRIs. In either case the rear
panel has 6 slots for the digital modems. They come in two flavors, 8 or 10
DSPs (modems) per card. So 6 times 10 gives you a mximum of 60 modems per
chassis. Dial-up support includes analog modem 2400-33.6Kbps, ISDN 64K,
ISDN 56K, ISDN 56K data-over-voice.

Basically you are limited by the capacity of the T1/PRIs DSOs. For T1 its
24 channels, for PRI its 23. If its a the T1 is configured for CT1 robbed
bit you can accept either modem or ISDN data-over-voice calls. If you
configured for PRI you can add to support for ISDN 64 and 56K calls.
