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 SLTs. 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:
Extension to Extension 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, SLTs can perform extension-to-
extension touchtone signalling; however, many proprietary telephones cannot. Some PBXs
need to be programmed to make proprietary telephones use touchtone signalling.
If the PBX does not provide extension-to-extension touchtone signalling, VPS services and
features will be limited.
Message Waiting Notification from an SLT
The PBX extensions should light a lamp or receive broken dial tone when the Message-
Waiting-Lamp-On code is dialled by the VPS. The VPS functions best when the extension
number of the voice mailbox owner follows the Light-On or Light-Off code. On some PBXs,
however, the extension number is dialled first, followed by a flash (recall) and then the On
code. This presents a problem if the extension is answered before the VPS sends the flash
(recall) signal.
If the PBX does not provide message waiting notification from an SLT, the VPS can only
notify mailbox owners by dialling a beeper (pager) or user-assigned extension number.

Minimum Loop Current
20 mA
Minimum Line Voltage
7 V DC
Minimum Ringing Voltage
40 V AC
TEST:Call an SLT extension from the telephone in question. When the call
is answered, see if the person receiving the call hears touchtones when
numbers are dialled.
