The DS1 maintenance switch
commands are used to allow the T-BERD 107A
to change the configuration. The
RESULTS
switch is used to select the DS1 maintenance
switch command.
Arm/Disarm
— Selects the maintenance
switch arming/disarming code. An arming
code (
LOOP UP
switch) is transmitted
down the repeater span to prepare the main-
tenance switch to loop up or switch a chan-
nel upon receipt of the appropriately
addressed code.

is in loopback mode. If it is in loopback
mode, the switch returns an address code. If
is not looped, the switch returns a bit error
count of 1350. Press either the
LOOP UP
or
LOOP DOWN
switch to send the query
code.
Restore
— Loops down the maintenance
switch and restores normal operations. Press
either the
