GUIDELINES FOR INTEGRATION
3.1.1
APT/DPT or Inband Signalling?
There are 3 types of integration available on the KX-TVP50: Inband Signalling, APT and DPT.
The VPS used with any other brand of telephone equipment requires inband equipment.
KX-TA series PBX can use APT Integration. KX-TD series PBX can use DPT Integration.
3.1.2
Why Integration is Important
The KX-TVP50 works well with most PBXs because its connections are made through a
standard single-line (tip/ring) telephone interface. However, the VPS operation depends on the
capabilities and features provided by the PBX; its performance will vary when connected with
different PBX systems. For example, Follow-on (or Called Party) ID is a feature of the PBX.
If the PBX does not have this feature, the VPS cannot transfer calls directly to the correct
mailbox and play the busy or no-answer greeting for that mailbox.
3.1.3
How the VPS and the PBX Communicate
To the PBX, the VPS looks like an SLT. The PBX thinks that the VPS is an SLT, and the VPS
mimics all actions a live attendant would carry out from an SLT.
For the VPS and the PBX to communicate, proper signalling is important. Like an attendant,
the VPS places calls by going off-hook and dialling numbers. It starts call transfers with a flash
(recall) to put callers on hold and then dials the extension number. By recognising call progress
tones from the PBX, the VPS decides how calls should be handled. Inband Integration allows
the PBX to send certain digits (touchtone) to the VPS, allowing it to recognise the status of the
extension and take the appropriate action.
The VPS must also have access to certain PBX features. For example, if the VPS takes a
message, one way it can notify the mailbox owner is by dialling the PBX's Message-Waiting-
Lamp-On code. Once new messages are retrieved, the VPS dials the Message-Waiting-Lamp-
Off code for that same mailbox owner.
