Obtain required equipment
To physically connect a data module to the system, you need the following parts.
■ 105C/D Isolating Data Interface (if connecting to a DC cabinet).
■ EIA-232-D (RS-232-C) cable with a male connector (for the data module)
and the correct connector for the peripheral equipment.
The cable connects the PC to the data module.
■ Null-modem converter (optional).
■ V.35 cable with correct connectors (not required by all systems).
■ D8W telephone cord.
The cord connects the data module’s LINE jack to the DEFINITY wall jack.
■ DCP telephone and D8W cord (optional).
The D8W cord connects the telephone to the data module’s PHONE jack.
■ Suitable auxiliary power supply if the optional telephone is installed (D7AP
power cord and 400B2 adapter in the US, international power supply, such
as the MSP-1, elsewhere).
You must have access to the administration console of the DEFINITY, either
through a terminal and keyboard or through a PC.
A breakout box for RS-232 interfaces may prove helpful in some cases. The RS-
232 breakout box helps you to identify the pin configuration of the RS-232
interface on the equipment you are trying to connect.
Set hardware options
Depending on the data module, you may have to set various configuration options
using hardware switches, software commands, or both. You must set the
hardware options before you administer or physically install the data module.
Setting 7400A data module hardware options
Most configuration options are controlled by commands entered on the front panel
of the 7400A. But you have to make hardware changes when you want to set up
the 7400A data-module for use in a modem pool or as a piece of data
communications equipment. In a modem-pool, the data module operates as data-
terminal equipment (DTE). In most other applications, it functions as data
communications equipment (DCE). You have to set the correct operating mode for
the data module before you can access the menus for the remaining configuration
tasks.
