Changing the Dial-Up/Leased-Line Jumpers
As shipped from the factory, your modem is configured for normal dial-up operation. That is, the
modem must dial a phone number to connect to another modem. To use the modem on a leased line,
you must change jumper J10 to select leased line operation, and J11 to select whether it will be the
originating or the answering modem. If dial-up operation is selected, J11 has no effect.
See Chapter 3 for additional leased line information.
·
The factory default is the answer position. This makes the modem the answering modem on the
leased line.
·
To use the modem on a leased line, move the J10 jumper plug from the default dial-up position to
the leased line position.
·
To make the modem the originating modem on the leased line, move the J11 jumper plug to the
originate position.
Changing the Voice Jumper
The speaker jumper (J8) is next to the external speaker jack (see Figure 2-2).
·
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 J8 jumper.
·
To use the modem with a monophonic external speaker, remove the jumper plug from the J8
jumper pins. You can store it by placing it on one jumper pin.
