cisco and t1 line question

[Theodore Knab <tjk@annapolislinux.org>]

I have a Cisco/Local T1 Loop question. 

We have a local T1 line between a building in town and our location.

Verizon leases us the line.

The Verizon line tech says that the linecode is switching between b8zs and ami.

In the router config, the 'line code' for the interface connecting to the T1 is not defined.

Would specifying the 'line code' in the Cisco router config prevent this switching ?
