Usage
Enter b8zs for T-1 facilities that support voice and/
or data traffic. Enter b8zs if you need a 64K clear
channel.
Enter ami-zcs only for T-1 facilities that carry voice
traffic: Avaya does not recommend this for
digital-data applications. If you anticipate upgrading
this facility to ISDN, use b8zs line coding if possible.
Enter ami-basic for unrestricted E-1 facilities.
Enter hdb3 for restricted E-1 facilities.
Used in Japan, cmi is the only type of line coding
you can use with the Japanese 2Mbit trunk circuit
pack. This field becomes a display-only field when
you are administering the Japanese 2Mbit trunk
circuit pack.
