31. Determine circuit pack option switch settings from office records or work order.
32. NOTE:
DS1 line coding may be set using either the option switches OR the
set-t1: command. It is recommended that a policy be established to
set line coding using either the switches OR the command. If DS1 line
code (lc) parameters are set using the set-t1: command, a software
override will be active and the circuit pack switch settings will have no
effect. The software override will remain active until the set-t1:
command is executed again and the noOverride option is selected.
The rtrv-t1: command may be used to check line code settings.
Refer to Table N and Figure 9 and set the line code option switches, if
required.
33. STOP. YOU HAVE COMPLETED THIS PROCEDURE.
