Ah yes... I've heard of DAHDIRAS but never looked into it.

My primary interest in starting this thread was simply to see if I could use the cards for data access since I have a couple lying around and would like to setup a 1.5mbit T1 circuit between them for data usage. My last post was more of a curiosity type thing. :-) Thanks for the pointers. Tim Nelson Systems/Network Support Rockbochs Inc.
