Cabling Your Modem

Connecting the Modem to the Phone Line

The only required connection is between the modem and a phone line. To connect the modem to the phone line:

1. Plug one end of the phone cable into the modem’s LINE jack.

Note: The LINE and PHONE jacks are not interchangeable. Do not plug the phone into the LINE jack or the line

cable into the PHONE jack.

2. Plug the other end into a phone wall jack.

Note: The Federal Communications Commission (FCC) and Industry Canada impose certain restrictions on

equipment connected to public telephone systems.

Changing the Voice Jumper

The speaker jumper is next to the external speaker jack.

● The factory default position of the voice jumper is set for a stereo speaker or sound card. A jumper plug

covers both pins of the jumper. 

● To use the modem with a monophonic external speaker, remove the jumper plug from the jumper pins. You

can store it by placing it on one jumper pin. 

Connecting a Phone (Optional)

To use a phone on the same line as the modem:

Plug the phone cord into the modem’s PHONE jack.

Note: The LINE and PHONE jacks are not interchangeable. Do not plug the phone into the LINE jack or the line

cable into the PHONE jack.

Connecting a Microphone and Headphone (Optional)

To use your modem with voicemail, connect it to a microphone and external speaker, headphone or sound card.

You can use the microphone to record voicemail messages and with a speakerphone. Use the speaker or

headphone to play back messages or as a speakerphone.

Use an unamplified microphone and headphone with a stereo 3.58mm (9/64-inch) mini plug. Do not use a

monophonic microphone.

Plug the microphone into the MIC jack.
