Data Modules and Asynchronous Data Units

Understanding RS-232 communications

Data Modules and Asynchronous
Data Units
Data modules connect peripheral equipment to the DEFINITY ECS or DEFINITY
ONE and convert between the RS-232 communications protocol used by
peripherals and the DEFINITY Digital Communications Protocol (DCP). Possible
peripherals include AUDIX adjunct equipment and terminals, serial printers,
customer-supplied terminals and host computers, call detail-recording (CDR)
devices, and pooled modems. The following data modules are described in this
chapter, and
7400A/B/C/D
8400B
ExpressRoute 1000
Asynchronous data units (ADUs).
NOTE:
ISDN data modules, such as the 7500B, are not covered in this book. Refer
to Integrated Services Digital Network (ISDN) 7500B Data Module User's
Manual, for detailed procedures. ISDN data modules connects DTE and
DCE equipment to the ISDN network using an RS-232 or V.35 interface and
an RS-377 automatic calling unit.
Understanding RS-232
communications
To install a data module, you have to set up the device to work with RS-232
devices.
Figure 10 shows typical data-module connections.
