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).
