Description

This command specifies the line encoding for a T1 or E1 line. ami can be applied to either T1 or E1; b8zs can be used only for T1 lines, and hdb3 only for E1 lines. The encodings used must match at both ends of the line; in practice, this means that the encoding is defined by your carrier.
