AUXILIARY
FUNCTIONS
The AUX PGM LPDN function enables a 3- to
8-bit user-defined loop-down code to be programmed.
This allows the T-BERD 107A to transmit and
respond to non-standard loop codes. The loop code is
transmitted from left to right as displayed. The pro-
grammed loop-down code is transmitted when the
LOOP CODES switch is set to PROG and the LOOP
DOWN switch is pressed.
When the T1, T1 D4, T1 D1D, or T1 SLC mode
is selected, the loop code is transmitted as an in-band
loop code. When the T1 ESF mode is selected, the
loop code can be transmitted in-band or out-of-band
depending on the AUX CSU LOOP function setting.
Use the following procedure to program the
loop code.
