8 MultiModemISI Hybrid Series, ISIHI-2S
Chapter 1– Introduction
ISIHI-2S modems offer interactive automatic dialing as well as Command Mode option
configuration. You can store up to ten command line/telephone numbers (up to 60
characters each) in the ISIHI-2S’s nonvolatile memory.
ISIHI-2S modems offer pulse or tone dialing and recognize dial tones and busy signals
for reliable call-progress detection. They detect AT&T calling card tones and are FCC-
registered for connecting to telephone networks without Data Access Arrangements
(DAAs).
They also feature Remote Configuration, which allows you to assist users at remote
sites, saving you the time and trouble of site visits and preventing misinterpretation of
configuration instructions.
The ISIHI-2S meets the CCITT V.17 standard for sending and receiving faxes. When
lined to a compatible fax machine or modem, ISIHI-2S modems can transmit faxes at
14.4 Kbps. They meet the CCITT’s Group 3 Designation for sending and receiving faxes
at 9600 bps and Group 2 Designation for sending and receiving faxes at 1800 bps. The
ISIHI-2S also is downward-compatible to speeds as low as 300 bps, so you can send
and receive faxes with virtually any fax machine in the world.
Terminal Adapter Description/Features
ISIHI-2S terminal adapters have S/T ports to connect to the ISDN network and analog
ports to connect to a telephone, modem, or fax machine. They ship with a software
configuration utility for Windows® 95, Windows NT, and ConfigMenu (a built-in
configuration utility for DOS and Windows 3.x operating systems). The TAs also accept
AT commands, enabling them to use the same communications software as analog
modems.
ISIHI-2S terminal adapters are compatible with EuroISDN switch protocol. They
communicate using ISDN BRI (2B+D) service, which provides up to 128 Kbps data and
voice communications. They automatically detect whether an incoming call is voice or
data and handle it appropriately.
The ISIHI-2S terminal adapters communicate over public ISDN telephone lines. Features
include the following:
• Compatibility with NET3, AT&T 5ESS, NT DMS-100, US National ISDN-1switch
protocols
• Automatically detect if incoming call is voice or data
• ISDN BRI (2B+D)
