What the heck are you talking about? AMI robs the least =
significant bit in each timeslot and sets it to a 1 ensuring ones =
density to recover clock from the line. It might even be argued =
that AMI is better than B8ZS at maintianing synchronization on a =
T1. With B8ZS, when a string of 8 zeros is encountered (which is =
very common when sending ACTUAL data) a bipolar violation occurs =
on the line and a special bit pattern is inserted.
The downfall of AMI, is that it only supports 56k timeslots as =
opposed to 64k timeslots which can be acheived with the use of =
B8ZS. =20
