Use the [←] [→] arrow keys to select the parameter to edit. Select either appropriate G.703 code using the [↑] [↓] arrow keys, then press ENTER.

Note that the choices displayed here will depend on the G.703 interface type, which has been selected. The choices are:

HDB3 (for E1, E2 or sub-rate operation)

B8ZS ( for T1 and unbalanced T2 operation)

B6ZS (for balanced T2 operation)
