Digi DialServ using V23 1200/75 (7910 modem)


I want to solve the following problem;

I have many RTU’s in the field who are equiped with 7910 modems (v.23 1200/75 switching modem) and 28k8 embedded modems. (pots/pstn)

On the other end is a proprietary modembank.

Is it possible to build a kind of GPRS tunnel between this equipment using the Digi Dailserv?

Thank in advance,
