Command Usage
Specify line coding of voice port.
Syntax Options
Remarks
AMI line coding is supported when the voice daughtercard connection port interface type is
set to T1, E1, E1 ISDN PRI, or BRI Euro via the
set to T1, E1, E1 ISDN PRI, or BRI Euro via the
voice port interface type
command.
The term dsx1AMI refers to a mode wherein no zero code suppression is present is used on
the link because line encoding does not solve the problem directly. In this application, the
higher layer must provide data which meets or exceeds the requirements, such as inverting
High Level Data Link Control (HDLC) data. E1 links, with or without a Cyclic Redundancy
Check (CRC), use dsx1AMI line coding.

B8Zs line coding is supported when the voice daughtercard connection port type is T1. The
term dsx1B8ZS refers to the use of a specified pattern of normal bits and bipolar violations
which are used to replace a sequence of 8 zero bits.
