Product Overview

The RocketModem multimodem card is Hayes

®

compatible and contains four or six RJ11 modem ports,
depending on the model, that can operate at speeds up
to 56 Kbps.

RocketModem features for this model include:

Four or six RJ11 modem ports

Bootable diagnostic tests on diskette

Individual software controlled modem reset
capability

Note: See the Software Installation and Configuration

Guide for information about installing software,
the AT command set, and using the reset feature.

Note: If the Comtrol RocketModem is not among the

modem models listed in your software
applications modem list, you can select
SupraFAXModem 288(336) for fax emulation and
Zoom Telephonics Zoom V.34X for modem
emulation.

Utilizing V.90 Technology

All V.90 modems are analog line devices. The following
figure shows when you can and cannot achieve 56 Kbps.

V.90 modems can receive data at rates up to 56 Kbps,
provided the data is being transmitted by a digital
modem on a digital (e.g., T1 or ISDN) line.

V.90 modems can send data over analog (twisted
pair) phone lines at a maximum rate of 33.6 Kbps—
even if communicating with other V.90 modems.

The actual data rate achieved depends on the age
and condition of the analog phone lines, and may be
lower than 33.6 Kbps.

European: Before Installing Hardware

CAUTION

Before installing this card, ensure that the power drawn
by this card, together with the host and any auxiliary
cards drawing power from the host, is within the rating
of the host power supply. Equipment must be installed
such that, with the exception of connections to the host,
the clearance and creepage distances shown in the
following table are maintained between the card and
other assemblies that use or generate the voltages
shown in the table. The larger distances shown in
(brackets) apply where the local environment within the
host is subject to conductive pollution or dry non-
conductive pollution which could become conductive due
to condensation (Pollution Degree 3 environments).
Failure to maintain these minimum distances would
invalidate the approval.
Note: Obtain advice from a telecommunications safety

engineer for a host or other expansion cards fitted
in the host using or generating voltages greater
than 300 V (rms or dc).
