Installing and Cabling the Cabinets

5.Set the Modem Connection: field to external if a modem is installed. Set the field to none if no modem is installed. This field must be administered or alarms will be generated.

Note:

The Modem Connection: field cannot be set to none if Alarm Origination is activated.

6.Set the Data Bits: field to 8 (default).

7.Set the Parity: field to none (default).

8.For non-United States installations, set the remaining modem fields as shown in Table 29.

9.Press Enter when the modem fields are properly administered.

Field

Description

 

 

Modem

Default is none. Set to external if a modem is used.

Connection

 

 

 

Modem Name

This field is 20 characters long and permits alphanumeric

 

characters to provide a unique qualifier for a given modem.

 

 

RTS/CTS

Informs modem that communication with the data source UART

Enabled

is driven with RTS/CTS flow control. The default 6-character

 

field name is &H1. Set the field name to \Q3 for Intel modems.

 

This field is not case-sensitive.

 

 

Asynchronous

Configures modem as an asynchronous device. This

Data Mode

8-character field name has a default value of &M0 (default). Set

 

the field to &M0&Q0 for Intel modems. This field is not

 

case-sensitive.

 

 

DTE Auto-Data

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

Speed

outgoing (modem-to-modem) data rate. At maximum, this speed

 

is 9600 baud. It is 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 6-character blank

 

default value. The Paradyne products use S90=1 to enable this

 

functionality while the Intel product uses \J1 to enable similar

 

functionality. This field is not case-sensitive.

 

 

Disable Data

Turns off the default data compression algorithms used 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.
