Managing Data Calls
7400C High Speed Link
The 7400C high-speed link (HSL) is a data-service unit that allows access to DCP data
services. It provides synchronous data transmission at speeds of 56- and 64-Kbps and provides
a link to high-speed data networks. Used for Group 4 fax applications that include electronic
mail and messaging, and electronic storage of printed documents and graphics. Use the 7400C
for video teleconferencing and LAN interconnect applications.
7500 Data Modules
The 7500 Data Module connects DTE or DCE to the ISDN network. The 7500 Data Module
supports EIA 232C and V.35 interfaces and RS-366 automatic-calling unit interface (for the EIA
232C interface only).
The 7500 has no voice functions. Configure in the following ways:
Asynchronous DCE
●
300, 1200, 2400, 4800, 9600, 19200-bps
Synchronous DCE
●
1200, 2400, 4800, 9600, 19200, 56000, 64000-bps
Asynchronous DTE (used for modem pooling)
●
up to 19200-bps
The 7500 Data Module is stand-alone or in a multiple-mount housing.
Asynchronous Data Module
Note:
The alias station command cannot be used to alias data modules.
Note:
Use the Asynchronous Data Module (ADM) with asynchronous DTEs as a data stand for the
7500 and 8500 Series of ISDN-BRI phones, thus providing connection to the ISDN network.
The ADM provides integrated voice and data on the same telephone and supports data rates of
300, 1200, 2400, 4800, 9600, and 19200-bps. This module also supports the Hayes command
set, providing compatibility with PC communications packages.
