SING THE

ODEM

Introducing the

Compaq 56K

Modem

The Compaq 56K modem is a controllerless modem with

superior data and fax capabilities.

✎

Controllerless modems operate using code that partially

resides in the operating system rather than in the modem

board.

Microsoft Windows 95 contains the code needed to control

the Compaq 56K modem. If you install Microsoft Windows

NT Workstation 4.0 on the computer, you must obtain a

special device driver for the modem. The necessary driver

may be downloaded from the Compaq Web site at

www.compaq.com/products/communications/56K_pres.html

or ordered from your Compaq authorized dealer, reseller, or

service provider.

K56Flex technology bridges the gap between current analog

communication (33.6K modems) and fully digital

communication (Integrated Services Digital Networks or ISDN).

This means that your 56K modem, which uses K56flex

technology, can take advantage of the higher speeds of digital

phone networks without expensive telephone line upgrades.

Modem Features

You can use your modem to

■

Receive Web pages and data from an Internet Service

Provider (ISP) at modulation speeds up to 56 Kbps.

✎

The K56flex protocol is designed only to allow faster

receipt of data from K56flex compliant sources.

Maximum achievable data transmission rates will vary

with line conditions.

■

Send data at modulation speeds up to 33.6 Kbps.

3-2 Using the Modem

Pages: 6 Words: 1335 Template: c:\msoffice\templates\comm.dot

File Name Ch3.doc Part Number 327557-001

■

Send and receive computerized faxes at modulation speeds

up to 14.4 Kbps.

Using the Modem

Connect the modem to a phone line as shown in Chapter 1,

“Getting Started.”

Your operating system includes some basic communications

software. For information on setting up and using this software,

refer to the Microsoft operating system documentation that

came with your computer.

There are also many third-party communications software

applications available to download or purchase. Be sure to

choose one designed specifically for Windows 95 or Windows

NT.

✎

If running Windows NT, you must also download a special

device driver from the Compaq Web site at

www.compaq.com/products/communications/56K_pres.html

or order it from your Compaq authorized dealer, reseller, or

service provider.

If you install third-party communications software for use with

your modem, the setup program usually prompts you to enter

information about your modem. Here are some tips for

configuring the software for use with your modem:

■

When prompted to select your modem, choose your

modem’s model. If your modem is not listed, select Hayes

compatible modem.

■

Set up the program to use COM Port 2.

In some cases you may want to send special commands to your

modem. If needed, a modem AT command reference is

available on the Compaq Web site (www.compaq.com). Refer

“Modem Compatibility” later in this chapter for a list of the

communications specifications, protocols, and AT command

sets supported by your modem.

Troubleshooting the

Modem

Some considerations may affect the modulation speed at which

your modem communicates.

■

Your modem can receive data from a compatible Internet

Service Provider (ISP) at up to 56 Kbps. Your modem can

send data at a maximum speed of 33.6 Kbps.To ensure the

fastest possible connection, be sure that

File Name Ch3.doc Part Number 327557-001

❏

Your ISP supports the K56flex protocol or a

compatible communications protocol.

❏

There is only one analog connection in the link. This

means that your call must go directly to your ISP or be

switched to a digital (not analog) line on its way there.

■

The maximum communication speed on a call is determined

by the speed of the slowest modem on the connection. Your

modem automatically negotiates the fastest possible speed

with the modem you dial.

■

Phone line conditions may affect the speed at which your

modem actually communicates on any given call. Your

modem is designed to automatically establish a reliable

connection at a lower speed if required to overcome noise or

other impairments on the telephone line.

Canadian Regulations Governing the Use of Modems

✎

The Industry Canada label identifies certified equipment.

This certification means that the equipment meets certain

telecommunications network protective, operational, and

safety requirements. The Department does not guarantee the

equipment will operate to the user’s satisfaction.

Before installing the equipment, users should ensure that it is

permissible to be connected to the facilities of the local tele-

communications company. The equipment must also be

installed using an acceptable method of connection. In some

cases, the company’s inside wiring associated with a single line

individual service may be extended by means of a certified con-

nector assembly (telephone extension cord). The customer

should be aware that compliance with the above conditions may

not prevent degradation of service in some situations.

Repairs to certified equipment should be made by an authorized

Canadian maintenance facility designated by the supplier. Any

repairs or alterations made by the user to this equipment, or

equipment malfunctions, may give the telecommunications

company cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical

ground connections of the power utility, telephone lines, and

internal metallic water pipe system, if present, are connected

together. This precaution may be particularly important in rural

areas.

CAUTION:

Users should not attempt to make such connections

themselves, but should contact the appropriate electric inspection

authority or an electrician.
