download speeds to 53,333 bps. It can also send or receive faxes at speeds up to 14,400 bps. With V.90 technology, your modem is capable of

receiving at up to 56 Kbps and sending at up to 31.2 Kbps. Actual download speeds you experience may be lower due to varying line conditions.

Compatible phone line and server equipment are required.

Features

Automatic Calling Card Dialing

Whenever you make a calling card call, your modem will detect the "bong" that sounds prior to entering your calling card number. You can set up

your modem to enter your calling card number and place your call automatically by entering the following string either in your communications

software or in terminal mode:

ATDT <phone#>&<calling card#>

Call Progress Detection

An optional set of result codes lets you know when:

The telephone number you have dialed is busy

The line has been picked up, but a modem is not answering the call

There is no dial tone on the telephone line

A call is coming in

These result codes, and the commands that enable or disable these result codes are controlled by the ATXn command. See ATXn in the Modem

Commands listing, and the Result Codes listing.

Dialing Stored Phone Numbers

Your modem can store up to four of your most frequently called numbers (

dialing stored phone numbers in the AT Commands section.

For example, suppose you are dialing a phone number of 123-4567, and it is the first number you want to store. Enter AT&Z0=1234567 to store

the number, and ATDS0 to dial it. To dial the second phone number in the list, you would enter AT&Z1 to store it, and ATDS1 to dial it.

Digital Line Guard

Your modem must use an analog line. If you are in an office and you are not sure what type of line you are connecting to, check with your telephone

company or telephone administrator. If that is not possible, use a line that is connected to a fax machine or another modem. If you only have a

digital line, you may be able to request a data line from your telephone company or telephone administrator.

The Mini PCI 56K Modem is equipped with a digital line guard to protect it if you accidently connect to a digital phone line. If, after you have

connected the cables and entered the communications software, a sound is made and this message appears:

SEE MODEM USER REFERENCE

PHONE LINE NOT VALID

"DIGITAL LINE ERROR"

Disconnect your telephone cable immediately! This means the modem is connected to the wrong kind of telephone line, like a line from a digital

PBX system. To use your modem, see if your digital PBX or telephone has a data port or look for a separate analog modem or fax line to use.
