Dialogic® Diva® TTY driver

The Dialogic

Diva

ISDN serial driver provides access to analog, digital, fax (FAX CLASS 1 and FAX CLASS 2

with ECM, compression, and polling support), V.110, B-channel protocol detection, caller ID, and voice

capabilities of the Dialogic

Diva

Media Boards by providing a standard serial driver interface. This allows for

using Diva Media Boards in a variety of configurations:

• As a "one number" Remote Access Server (RAS) with automatic protocol detection and ASYNC/SYNC framing

conversion, allowing multiple incoming analog, digital, and wireless connections. These connections may be

simply login sessions or IP (Internet Protocol) over PPP (Point-to-Point protocol) connections.

• As a fax polling server, in combination with third party fax software that works with fax modems. Supports

polled document selection and protection.

• As a WAP (Wireless Application Protocol) gateway or WAP application server, using the V.110 protocol (or

combined with a RAS server).

• As a wireless application server, using the PIAFS protocol (or combined with a RAS server).

The status of the exposed driver ports by the Diva TTY can be controlled using the Dialogic® Diva® TTY

management interface directory (Port Manager) on page 95 of the driver, that is accessible using WEB-

based management interface browser or using the mantool command line utility, see Management interface

access and monitoring utility on page 89 for more information.
