AUXILIARY
FUNCTIONS
The AUX AUTORESP function determines
whether or not the T-BERD 107A enters or leaves
automatic line loopback mode (AUTO LLB) in
response to received loop codes. Press the
RESULTS
switch to select one of the following:
NO RESPONSE — T-BERD 107A does not
respond to received loop codes.
AUTO RESPONSE — T-BERD 107A auto-
matically responds to received loop codes by
enabling or disabling the AUTO LLB mode.
The instrument only responds to loop codes
matching the loop code selected from the AUX
CSU LOOP function or AUX NIU LOOP func-
tion. If the T-BERD 107A is set to T1 TLB or T1
LLB mode, the instrument does not respond to
the received loop codes.
When the AUX AUTORESP function is set to
AUTO RESPONSE, the T-BERD 107A enables the
AUTO LLB mode after receiving five seconds of
in-band loop-up code or after receiving 250 ms of
ESF out-of-band loop-up code. The AUTO LLB
mode is disabled after receiving the in-band or ESF
out-of-band loop-down code. When AUTO LLB
mode is disabled, the instrument returns to the previ-
ously selected operating mode. Refer to the
MODE
switch description in Section 3 Instrument Descrip-
tion for more information on the AUTO LLB mode.
