This has to do w/line coding on channelized T1s and the overhead to keep track of channelized info. If the other end isn't using Clear 64, and is using AMI(a line encoding scheme from telco)then 8 Kbps is used to synchronize between the two ends. Chris -Original Message- From: [EMAIL

could also be that the router itself is set to respond to 56K only, rather than the fault lying with the switch. - Don -Original Message- From: John Neiberger [mailto:[EMAIL PROTECTED]] Sent: Wednesday, July 05, 2000 2:03 PM To: [EMAIL PROTECTED] Subject: RE: 56k ISDN?? Thanks, that info hel

Hopefully they don't, but they used to use it all over the place, which is why it still exists in certain areas. - Don -Original Message- From: John Neiberger [mailto:[EMAIL PROTECTED]] Sent: Wednesday, July 05, 2000 1:58 PM To: [EMAIL PROTECTED] Subject: RE: 56k ISDN?? So, do ISDN
