PROBLEM PROBABLE CAUSE SOLUTION
• Extension telephone does
not function. • Faulty connection
between the PBX and
telephone. • Plug the telephone into the same
extension port using a short telephone
cord.
If the telephone functions, then the
connection between the PBX and the
telephone must be repaired.
• Faulty telephone. • Plug the telephone into a known
functioning extension port. If the telephone
does not function, replace the telephone.
• A telephone with an A-A1
relay is connected. • Use a 2-wire cord.
Set the A-A1 relay switch of the telephone
to the "OUT" or "OFF" position.
• Faulty extension card. • Exchange the card for a known functioning
one.
• Proprietary telephones
(PTs) connected to
extension jacks do not
operate, but single line
telephones (SLTs) do. • The H and L pins of
extension jacks may have
shorted. • Turn the Power Switch to the "OFF"
position. Fix the shorted part, then turn the
Power Switch to the "ON" position.
• Noise heard through
external pager
(loudspeaker). • If using an amplifier, noise
may be being introduced
through the cable
connecting the PBX and
the amplifier or
loudspeaker. • Use a shielded cable to connect the PBX
and the amplifier or loudspeaker. A shorter
cable will introduce less noise.
• Audio (Music on Hold,
Background Music) is
distorted. • Audio level from the output
of the audio source is too
high. • Decrease the output level of the external
audio source by using the volume control
on the audio source.
• Speed Dialing or One-
touch Dialing does not
function. • Incorrect programming. • Store the outside (CO) line access number
(for example, 9, 81 through 88) at the
beginning of the telephone number.
• Improper operation other
than the above. • Turn the Power Switch to the "OFF"
position, and then back to the "ON"
position.
