With Ascend's recomendations to only put 2 trunks in a 40xx, NFAS doesn't do anything... however if you have multiple MAX units all in a hunt group, you can configure them all as 23B+D/24B, then in the event of a D channel failure you WILL loose two trunks, but the hunt group will still have other Maxen. Of possible interest is that some CLECs charge more for a D than for a B, ex: A local access PRI from MCI, a B chan is $20-$30/month and a D chan is $100, so you save $70/mo per trunk pair to consolidate two trunks to one D. -Jim H ---- Jim Howard Sr Network Engineer Lyceum Internet jhoward@lyceum.com <A HREF="http://www.lyceum.com/">http://www.lyceum.com/</A> 404.248.1733 My PGP Public Key: <A HREF="http://www.lyceum.com/~jhoward/pgp-key.txt">http://www.lyceum.com/~jhoward/pgp-key.txt</A> Fingerprint: 7E8B E2BA 1314 2535 CB08 CFF9 119B 7CD3 2488 954D ++ 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--> <!--X-References-End--> <!--X-BotPNI--> <HR> <UL> <LI>Prev by Date: <STRONG><A HREF="msg11751.html">Re: (ASCEND) NFAS?</A></STRONG> </LI> <LI>Next by Date: <STRONG><A HREF="msg11747.html">Re: (ASCEND) Pipe75 dialing into Courier I-modem @128k</A></STRONG> </LI> <LI>Prev by thread: <STRONG><A HREF="msg11744.html">Re: (ASCEND) NFAS?</A></STRONG> </LI> <LI>Next by thread: <STRONG><A HREF="msg11713.html">(ASCEND) Best Version?</A></STRONG> </LI> <LI>Index(es): <UL> <LI><A HREF="maillist.html#11748"><STRONG>Main</STRONG></A></LI> <LI><A HREF="thrd279.html#11748"><STRONG>Thread</STRONG></A></LI> </UL> </LI> </UL> <!--X-BotPNI-End--> <!--X-User-Footer--> <!--X-User-Footer-End--> </BODY> </HTML>
