Connecting Asterisk to an External Modem

Hi everybody,

This question may seem very rudimentary; however, as newbie I can not figure out how to connect my acorp serial Data/Fax/Voice external modem to Asterisk. I would be grateful if anybody could kindly help me with some recommendation.

You want to use the mode to make calls. AFAIK there are very limited modems that work with asterisk and the one you have listed here does not ring a bell.
