AUXILIARY
FUNCTIONS
Sequential Loopback
— Loops up and
loops down the T1 line repeaters on the
span in sequence starting with the repeater
nearest the T-BERD 107A and proceeding
down the span, regardless of the repeater’s
address. Pressing the
LOOP UP
switch
transmits the Sequential Loopback code.
The first time a repeater receives the se-
quential loop code, it loops up. The second
time the sequential loop code is sent, the
repeater loops down. Alternatively, the
LOOP DOWN
switch can be used to trans-
mit the loop down code, which loops down
the repeater. Regardless of which method
is used to loop down the repeater, it ignores
all subsequent sequential loop code trans-
missions until it is disarmed and re-armed.
Time-out Disable/Extend
— Disables/
extends the loopback timeout function of
the repeater. The line repeater loopback
should be established first, then the timeout
disable function is sent. The timeout func-
tion resets when the loopback is deacti-
vated remotely.
IOR PGM ADDR/ILR PGM ADDR
— Selects
the address change command, which allows the
T-BERD 107A to assign an address for the
intelligent repeater. Press the
RESULTS
switch
to assign the address in the range from 0 to 1999.
IOR PGM CMD, ILR PGM CMD
— The remote
programming commands allow the T-BERD
107A to activate specific functions of intelligent
office repeaters and intelligent line repeaters.
Remote programming can only be done from
the DSX side while the repeater is in loopback.
