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:

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

sequence. If your external TA cannot recognize these signals, then

select V.35 or X.21.

be configured properly for use with ISDN, and all require the user to
