Configuring the Modem’s Dual In-line Package (DIP) Switches

Quick-Reference

Configuration

The standalone modem has a 6-position DIP switch that lets you “hard” configure certain aspects of the modem’s operation. The modem is shipped from the factory with all switches in the Off (up) position. DIP switch selections cannot be overridden using the remote front panel configuration.

1

Off (up)

EIA/TIA 232-D Pin 23 is set for data rate input. Setting Switch 1

 

 

to this position has no effect on modem operation. NOTE: When

 

 

operating with a V.35 electrical interface, leave switch S1 in the

 

 

off (up) position at all times.

 

 

 

2

On (down)

EIA/TIA 232-D Pin 23 is set as a data indicator.

 

Off (up)

Busy Out select. A signal on EIA/TIA 232-D Pin 25 makes the

 

 

modem appear busy to incoming calls.

NOTES:

1)You must set DTE Pin 25=Busy (AT*LT, TERMINAL OPT’s category) to enable Busy Out Select.

2)The AT&J Telco option command must be set to RJ4MB.

On (down) Test Indicator Signal (V.24 Circuit 142) Select. The modem signals to the terminal on EIA/TIA 232-D Pin 25 (V.24 Circuit 142) when a test is in progress.

NOTES:

1)You must set DTE Pin 25=Test (AT*LT, TERMINAL OPT’s category) to enable Busy Out Select.

2)The AT&J Telco option command must be set to RJ4MB.
