You can do this, but not with the unchanellized DS1 card you'd normally expect to use for T1 customers. You must use the regular DS1 card and HDLC resources. > It's been suggested that it has to do with the nailed groupd in the T1/E1 > profiles and with setting up logical ip-interfaces. Yup. Your connection profile (if using PPP) or frame relay datalink profile (if using frame relay) nailed group parameter should have the same value that is shared by the channel groups in use by that customer. -Phil ++ Ascend Users Mailing List ++ To unsubscribe: send unsubscribe to ascend-users-request at bungi.com To get FAQ'd: <http://www.nealis.net/ascend/faq>
