For basic dial backup operation, these parameters do not need to be altered from their default val-
ues.
The
A
NSWER
A
LWAYS
option must work in conjunction with the
A
UTO
DBU
option. The
A
UTO
DBU
option is still the controlling option. If
A
UTO
DBU
is disabled, the unit will not answer the
call regardless of how
A
NSWER
A
LWAYS
is set. Examples of the various combinations and
expected results are shown below.
In addition, the
A
NSWER
A
LWAYS
feature must work in conjunction with the
O
RIGINATE
/A
NSWER
feature. The
O
RIGINATE
/A
NSWER
feature only appears when the unit is programmed for a non
frame-relay circuit (signaling none). If
A
NSWER
A
LWAYS
is enabled (and
A
UTO
DBU
enabled), the
unit will answer the call even if it is set to
O
RIGINATE
. Examples of the various combinations and
expected results are shown below.
The
B
EEPER
O
PTION
