While this doesn't seem to apply to Tony's case, I wouldn't make a blanket statements like that. If the T1 is provisioned ESF, yes you can get 1536 kbps, but there are places where you still can only get SF/D4 framing.
Why would SF/D4 framing reduce the available bandwidth? In some cases, if you can't get B8ZS line coding, and have to use AMI, you might have to drop to 24x56=1344kbps (and use one bit on each DS0 to maintin 1's density), but even then, if your routers or DSUs can invert the data, you can still go 24x64=1536kbps. (HDLC guarantees zero-density ... so if you invert it, you get guaranteed 1's density.) - Brett (brettf () netcom com) ------------------------------------------------------------------------------ ...
