programmed one-button functions. These four keys can also be set up
to close relay contacts on a far-end codec or to execute any remote
control or Logic Language command.
Selecting A Digital Interface Module (DIF)
If the DIF was not factory installed, or if you change DIFs, you need to
select the Digital Interface the first time you use the
RoadRunner
with
that DIF.
Once a DIF has been physically installed, you must set the
RoadRunner
to recognize the module. From the keypad, use the sequence:
<Maint><Dig I/F><Type><
Type
>
and scroll through the menu to select the installed interface. The choices
are:
TA101, TA201, TA301, X.21, X.21XTA, V.35, V.35XTA
and
RS422.
Select the appropriate interface and press
ENTER
. You can also use the
remote control command
CIF
from a terminal or computer. Select
V.35XTA or X.21XTA only if your external TA is capable of recognizing
DTR or CON signals for call termination. This allows you to terminate
a connection from the front panel of the
RoadRunner
. You can also
toggle the sense of the DTR line using the
<DIFx01><DTR/CON>
sequence. If your external TA cannot recognize these signals, then
select V.35 or X.21.
TA Configuration
It is necessary to configure a Terminal Adapter each time you connect
your
RoadRunner
to a different ISDN circuit.
Three different TAs are available for use in the
RoadRunner
. All must
be configured properly for use with ISDN, and all require the user to
have certain information, supplied by the ISDN service provider. The
following information must be known before configuring any TA for
use:
