I certainly don't want 50 or 60 AO/DI users checking their email every minute on a crutial D channel designed to pass signalling for some PRI's or something. I haven't been keeping up on the subject of AO/DI, so I'll ask the list... When will the first "test" devices be offered and what are the requirements? I am assuming it takes nothing special from the phone company. I am also am assuming that the end user only needs to have a destination Circuit ID or a tel.no would even work. > Peter Lalor > Infoasis > plalor@infoasis.com > <A HREF="http://www.infoasis.com/">http://www.infoasis.com/</A> > 415-459-7991 x102 > 415-459-7992 fax > -- Tim Connolly tec@mountain.net MountainNet, Inc. -- (800) 444-1458 ext. 37 2816 Cranberry Square -- fax (304) 594-9088 Morgantown, WV 26505 ++ Ascend Users Mailing List ++ To unsubscribe: send unsubscribe to ascend-users-request@bungi.com To get FAQ'd: <<A HREF="http://www.nealis.net/ascend/faq">http://www.nealis.net/ascend/faq</A>> </PRE> <!--X-MsgBody-End--> <!--X-Follow-Ups--> <!--X-Follow-Ups-End--> <!--X-References--> <HR> <STRONG>References</STRONG>: <UL> <LI><STRONG><A HREF="msg11804.html">(ASCEND) Re: NFAS?</A></STRONG></LI> <UL> <LI><EM>From</EM>: Peter Lalor <plalor@infoasis.com></LI> </UL> </UL> <!--X-References-End--> <!--X-BotPNI--> <HR> <UL> <LI>Prev by Date: <STRONG><A HREF="msg11813.html">Re: (ASCEND) 5.0Ap38 for the MAX products</A></STRONG> </LI> <LI>Next by Date: <STRONG><A HREF="msg11811.html">(ASCEND) Recommendations for a new router...</A></STRONG> </LI> <LI>Prev by thread: <STRONG><A HREF="msg11804.html">(ASCEND) Re: NFAS?</A></STRONG> </LI> <LI>Next by thread: <STRONG><A HREF="msg11810.html">Re: (ASCEND) Re: NFAS?</A></STRONG> </LI> <LI>Index(es): <UL> <LI><A HREF="maillist.html#11812"><STRONG>Main</STRONG></A></LI> <LI><A HREF="thrd282.html#11812"><STRONG>Thread</STRONG></A></LI> </UL> </LI> </UL> <!--X-BotPNI-End--> <!--X-User-Footer--> <!--X-User-Footer-End--> </BODY> </HTML>
