INTEGRATING THE VPS WITH PANASONIC KX-T PHONE SYSTEMS
Installation Manual
49
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.
3.1.4
PBX Requirements for Integration
The PBX must have certain capabilities and features to work with the VPS. (Although this
section includes tests to help you evaluate the PBX, it may be necessary to refer to the PBX's
documentation for detailed capability and feature descriptions.)
Single Line (Tip/Ring) Port Circuits
The VPS can only be connected to a PBX that supports SLT sets. Some PBXs need an OPX
card to provide this connection. However, some OPX cards do not provide all the capabilities
listed in this section.
Following are the minimum current and voltages that the PBX must supply:
Station to Station Touchtone Signalling
For system users to access VPS services and features, they must be able to send touchtones
from their telephones to the VPS port. As a general rule, SLT sets can perform station-to-
station touchtone signalling; however, many proprietary telephones cannot. Some PBXs need
to be programmed to make proprietary sets use touchtone signalling.
If the PBX does not provide station-to-station touchtone signalling, VPS services and
features will be limited.
