Modems?

It is calling digital, of course.

But ISDN is 64000. There must be some way this is adapted. Typical mobile
phone providers translate the GSM call to either analog V.32(bis), or
eventually to digital V.110.

Ask whether your GSM provider translates to analog, to V.110 or
provides both. For analog, you would need a modem card. For V.110,
Cisco might be able to deal with that, but I don't know exactly.
V.110 is digital, but a completely different framing compared to
what is usually used on the B-channel (HDLC-derived protocols). On
the Ascend Max, for instance, you need extra hardware (just like
the digital modems) to accept V.110, because the HDLC processors
could not cope with it. Maybe someone operating a Cisco NAS knows
more?
