From: "Robert E. Seastrom" <rs@bifrost.seastrom.com> Precisely. The most likely explanation is that the T1 is actually D4 framed, uh, my wrong... it's the AMI not the D4 that causes the big hit. of course, as a matter of course, D4/AMI and ESF/B8ZS go together and you never see combinations like D4/B8ZS... which, in answer to the fellow who asked, is why you can't just invert the data on the HDLC and run it down the line and get your 12% back... HDLC is layer 2, whilst framing is layer 1... ---Rob
