• If the modem reports NO DIALTONE, check that
the modem’s telephone line cable is connected to
both the modem’s LINE jack (not the PHONE
jack) and the telephone wall jack. If the cable
looks secure, try replacing it. If that doesn’t work,
the problem may be in your building’s telephone
installation. To test the building installation, plug
a telephone into your modem’s telephone wall
jack and listen for a dial tone. If you hear a dial
tone, your modem may be installed behind a
company phone system (PBX) with an internal
dial tone that sounds different from the normal
dial tone. In that case, the modem may not
recognize the dial tone and may treat it as an
error. Check your PBX manual to see if you can
change the internal dial tone; if you can’t, change
your modem’s initialization string to replace X4
with X3, which will cause the modem to ignore
dial tones.
• If the modem reports BUSY, the other number
may be busy, in which case you should try again

a 9, prefix to the phone number if you must dial 9
for an outside line.
If you must dial 9 for an outside line, the easiest
way to dial it automatically is to include it in the
