Data Module
Figure 21-4. The 7400D Data Module
The 7400D Data Module is a full-duplex, 4-wire synchronous data module for the
DCP environment and is designed to work where the integration of voice and data
is not required. The 7400D supports synchronous connections at speeds up to
19.2 Kbps via an EIA-232-D interface.
NOTE:
This data module is configured for an Answer-Only-type interface.
You CANNOT originate calls with this data module.
The 7400D data module is intended for use in a switch room to support the AUDIX
systems, the Call Management System (CMS), and the Distributed
Communications System (DCS) low speed synchronous data applications,
connections in which the MPDM was formerly used.
Applications
The 7400A Data Module can be used with the DEFINITY Communications
System Generic 1, Generic 2, and Generic 3, the DEFINITY ECS, System 75, and
System 85.
