16.2 Enabling and Disabling Auto-Answer
The number of rings that the ISDN TA/V will wait before automatically
answering a call is determined by the setting of S-Register S0. This can be
altered using the command
S0=
n
where
n
is a value from 0 to 255–This may
be restricted according to the regulations of the country in which the ISDN
TA/V is being used. The ring count is incremented every two seconds when
a call is present.
To disable this automatic answering facility the value of this S-Register should
be set to 0 (
S0=0
). The default setting is
S0=1
, indicating that (providing DTR
is high on the ISDN TA/V’s interface) the ISDN TA/V will automatically
answer a call after the first ring.
16.3 Causes of a Disconnection
This section details the commands and S-Register settings that determine

The length of time, in seconds, that an originating ISDN TA/V waits for an
answer from the remote modem or ISDN TA/V before abandoning the call
is determined by the setting of S-Register S7. The default setting is
S7=40
,
which can be altered using the command
S7=
n
where
n
is a value from
1 to 255 seconds. This range of values will be restricted according to the
regulations of the country in which the ISDN TA/V is being used. Entering
a restricted value will result in an error message being displayed.
