environment, together with any auxiliary apparatus, does not

exceed the power specification as stated in the Technical

Reference Material of the host apparatus. The power

requirements for the KeepInTouch Card modem are 5V and

1 Watt.

In order to maintain the independent approval of this card, it is

essential that other optional cards do no use (or generate)

mains Voltages or any other hazardous voltage. A hazardous

voltage is one which exceeds 42.24V peak a.c. or 60V d.c. If

you have doubt, seek advice from a competent engineer before

installing other adapters into the hoist equipment.

The equipment must be installed such that with the exception of

the connections to the host, clearance and creepage distances

shown in Table 1 are maintained between the card and any

other assemblies which use or generate a voltage shown in the

table. The larger distance shown in brackets applies where the

local environment within the host is subject to conductive

pollution or dry non-conductive pollution which could become

conductive due to condensation. Failure to maintain these

minimum distances would invalidate the approval.

Welcome to the World of

Portable, High-Speed Data

Communications!

Congratulations on your purchase of the AT&T Paradyne

KeepInTouch Card modem. The KeepInTouch Card is a credit

card size modem that combines high-speed V.32 bis data

communications with Group 3 send-and-receive fax capability.

The modem fits into any notebook or laptop personal computer

that has a Personal Computer Memory Card International

Association (PCMCIA) Release 2 socket and allows you to keep

in touch with your home or office from anywhere around the

world.

The KeepInTouch Card family of modems includes Models

3760, 3761, 3762, 3763, and 3764. This manual contains

information on Model 3760, Model 3762, Model 3763, and

Model 3764.

Model 3763 and Model 3764 are intended for international

(particularly European) applications only and are not for use in

North America.

The KeepInTouch Card high-speed modem can transmit and

receive information over a standard telephone line at 14,400 bits

per second. It is compatible with a variety of modem standards,

allowing it to communicate with slower modems. To ensure

error-free data transfers, the KeepInTouch Card modem

employs V.42 and MNP Levels 4–2 error control. To increase

effective data throughput and reduce the duration of calls, the

1-2 Issue 3 April 1994

modem utilizes both V.42 bis and MNP5 data compression

standards to achieve peak transmission rates up to 57,600 bps.

For fax operation, the modem supports both Class 1 and Class

2 fax standards. Class 1 fax places most of the processing

burden on the software while Class 2 fax places it on the

modem. In addition, the modem also supports the CCITT V.17

fax protocol which allows fax transfers to occur over standard

telephone lines at 14,400 bps. To take advantage of the 14,400

bps data rate, you must connect to a fax machine or fax modem

that also supports the V.17 protocol.

KeepInTouch Card modems Model 3762 and Model 3764 also

support transmission over a cellular network. These models use

the ETC (Enhanced Throughput Cellular) protocol which

improves data communications over cellular telephone

channels. For more information about cellular operation, refer to

Appendix D,

Cellular Communications

The Hayes AutoSync feature is also available in selected

models of the KeepInTouch Card modem. For more information

on Hayes AutoSync, refer to the

Using Hayes AutoSync

section

in Chapter 2,
