PROBLEM
Nothing is heard from the
VPS when accessing the
VPS.
Unable to utilise some of
the DPT Integration
features, even though DPT
Integration has been
established properly.
The VPS does not operate. •
Dialling is not registered.
PROBABLE CAUSE
• Improper connection of jacks.
• Bad connection with the PBX.
• Your PBX cannot support the
feature.
• The software version of your
PBX is lower than required.
Bad printed circuit board.
• Bad connection with PBX.
• Incomplete card insertion.
• A pulse telephone is being
used by mistake.
• Improper setting of
integration mode.
POSSIBLE SOLUTION
• Confirm that you are using the
correct extension number for
the VPS. Ask your System
Administrator.
• Check if the jacks of the VPS
are connected to the proper
jacks of the PBX (see 1.2
Voice Mail Integration).
• Check the System Program
[130] of the KX-TA series or
KX-TE series to see if the
programming agrees with the
actual connection.
• Check the "1-4 VPS (DPT)
Port Assignment" screen of
the KX-TD500, or System
Program [117] or [126] of other
KX-TD series PBXs, or the
"Groups-VM(DPT) Group-Unit
Setting" and "Configuration-
Extension Port" screens of
KX-TDA series PBXs that use
DPT Integration to see if the
programming agrees with the
actual connection.
• Consult your dealer.
• Change the printed circuit
board.
• Check the connection
between the VPS and PBX.
• Insert the card firmly into the
card slot.
• Change to a touch tone
telephone.
• Adjust the integration mode
properly between the VPS and
your PBX (see "Integration
Mode" in 2.5.4 Parameters in
the Programming Manual).
