External Modem Option Settings

The COMSPHERE 3700, 3800, and 3900 series (recommended) external modems may require option switch settings. Refer to the documentation that accompanies each modem to set the options.

NOTE:

Alocally obtained, type-approved external modem may be used. Contact your Lucent Technologies representative for more information.

The Release 6 systems operate with the COMSPHERE modems set to the factory default settings. The modem settings and descriptions are listed in Table B-1.

Table B-1. Modem Fields

 

Modem

 

 

 

Connection

Description

 

 

 

 

 

Modem Name

This field is 20 characters long and permits alphanumeric characters to

 

 

provide a unique qualifier for a given modem (such as INTEL).

 

 

 

 

 

RTS/CTS

Informs the modem that communication with the data source UART is

 

Enabled

driven with RTS/CTS flow control. The field name has a default of \Q3 in a

 

 

field 6 characters long. This field is not case sensitive. Default is upper

 

 

case.

 

 

 

 

 

Asynchronous

Configures modem as an asynchronous communications device. The

 

Data Mode

field name has a default value of &M0&Q0 in a field 8 characters long.

 

 

This field is not case sensitive. Default is upper case.

 

 

 

 

 

DTE

Adjusts the speed of the data source (DTE) UART to the outgoing

 

Auto-Data

(modem-to-modem) data rate. At maximum, this speed is 9600 baud. It is

 

Speed

not desirable to have the serial data fill the modem buffer faster than the

 

 

outgoing data rate, since data compression is disabled. The field name

 

 

has a blank default value in a field of 6 characters. The Lucent products

 

 

use the command S90=1 to enable this functionality while the Intel

 

 

product uses the command \J1 to enable similar functionality. This field is

 

 

not case sensitive. Default is upper case.

 

 

 

 

 

Disable Data

Turns off the default data compression algorithms in use by most

 

Compression

modems. The field has a blank field of 6 characters as default. The AT

 

 

commands that control this are supported by similar commands;

 

 

however, these commands do not operate in the same manner. The Intel

 

 

modems require “H0%C0” to disable V.42bis & MNP Class 5 data

 

 

compression algorithms. The Paradyne products only use %C0 to disable

 

 

both algorithms. This field is not case sensitive. Default is upper case.
