Changing Installation Options
Disable Busyout Feature During Local
Loopback Test
This option is set, by default, for
Yes
. The 8400B Plus Data Module will not
busyout the DCP line while performing a Local Loopback Test or Local
Loopback Self-Test.
Changing this option to
No
allows the 8400B Plus Data Module to busyout the
DCP line when either the Local Loopback or Local Loopback Self-Test mode is
entered. This will cause a busy signal when the set is called. The busyout
condition is released when the test ends.
NOTE:
A change in the setting of this option becomes effective immediately when
the 8400B Plus Data Module is in the idle mode or as soon as it is
returned to the idle mode. The 8400B Plus Data Module is in idle mode
any time that it is
not
in a test mode or connected to an active data call.
Changing Installation Options
All seven installation options are set in S-register S24 via a number that
represents their collective value.
■ To accept the default value of
Yes
for all options, leave the value of 0
(zero) in S-register S24.
■ To specify
No
for only one of the options, enter its value (see Table 2-1)
in S-register S24. For example, to change
Automatic Speakerphone
Activation
to
No
, enter
64
in S-register S24.
■ To specify
No
for two or more options, add together the value for each of
those options (see Table 2-1), and enter the total in S-register S24. For
example, to set
With Telephone
to
No
and
Disable Data Metering
Feature
to
No
, enter
17
in S-register S24.
