TELEPHONE OPERATION
PROBLEM
LINE Lights Remain
On When No Line is
Connected
PROBLEM
Tone Signals Do
Not Activate a
Remote Device
SOLUTION
• Make sure the phone is programmed
for that line to be absent. (See "Turn
Line Usage On or Off for Each Line"
on page 33.)
• Make sure that your Line Groups are
programmed properly. (See "Assign the
Line Group for this Phone" on page 41.)
• Disconnect all other devices (fax, modem,
credit card reader, etc.) from any lines
connected to your 984 phone. These
devices can interfere with the telephone's
data links.
• Make sure the total length of telephone
wiring used in your phone system is less
than 600 feet. In some cases a Z800A
filter can be used in a phone system with
more than 600 feet of wire. AT&T highly
recommends that a Z800A filter be installed
by a professional. AT&T CANNOT
guarantee that this telephone will work
with such a filter, and IS NOT responsible
for such installations. A Z800A filter can
be obtained by calling
(See "DSL Users" beginning on page 4 for
details.)
SOLUTION
Tone signaling does not work during
conference calls.
