I assume you mean T1 PRI lines with 23 B channels and 1 D channel. This would support 23 simultaneous calls on each T1. You might also mean T1 DCS (aka channelized T1) with 24 B channels and in-band signalling. This would support 24 simultaneous calls on each T1. > Is that actually the case? Will there be any adverse effects if I would > terminate 4 T1s, and have only 2 T1s running to each of the MAXes? Depends. Are you accepting ISDN calls? If so, you need 1 or 2 channels on a T1, depending on bandwidth provided, for each caller. If you are purely modem calls, then common practice is to have a couple more modems in your pool than B channels. This prevents your customers from getting a rings, no-answer condition because a few modems are out of service or otherwise unavailable.
