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 B and Figure 1 and set the line code option switches, if required.
