VOICE PROCESSING SYSTEM OVERVIEW
We cannot guarantee adequate integration of the KX-TVP50 with other PBX systems or with
Key Systems. If the customer does not have one of the recommended Panasonic PBX
systems, be sure that the system has the features listed below.
The PBX should have the following features for successful integration:
• Single line (tip/ring) port circuits (Some PBXs need an OPX card to provide this
connection.)
• Extension to extension touchtone signalling
• Message Waiting Notification from an SLT (single-line telephone)
• Screened transfer from an SLT
• Message Waiting Notification on proprietary (multi-line) sets (message waiting lamp
accessed by dialling on/off codes)
If the PBX does not have these features, VPS operation will be limited.
See 3.1.4 PBX Requirements for Integration. You will find the following information about
each feature listed:
• Description
• Limitations of the system without the feature
• Tests to determine whether the PBX has the feature
VOICE MAIL
The recommended Panasonic PBX systems have Follow-on ID and Inband Integration. When
callers are transferred to an extension that is forwarded to Voice Mail, Follow-on ID sends
callers directly to the mailbox. Without Follow-on ID, the caller would have to re-enter the
mailbox number when connected to the Voice Mail.
Touchtone Integration enables the VPS to recognise the current state of the call and improve
its call handling performance. When enabled, the PBX informs the VPS of the status of the call
(busy, answered, ringing, etc.) by sending a code with touchtones before sending the normal
call progress tones. For example, when a caller hangs up before making a selection, the PBX
sends # 9 to the VPS port that answered. This informs the VPS that the caller has hung up.
Upon receiving these digits, the VPS goes on-hook and is ready to handle another call.
Digital (APT/DPT) Integration is available when the VPS is connected to a Panasonic KX-TA
series PBX or to a Panasonic KX-TD series PBX (depending on the software version). This
digital integration provides the VPS with more information than Touchtone Integration. This
information enables the system to identify the extension number of the caller, know where the
call is forwarded from and why, and recognise what the caller wants to do. Some features are
available only with APT/DPT Integration (Remote Call Forwarding Set, Live Call Screening,
Two-Way Recording, Two-Way Transfer, Direct Mailbox Access, Intercom Paging, Auto
Configuration, Caller Name Announcement [system/personal], Caller ID Call Routing,
Personal Greeting for Caller ID, Time Synchronisation with PBX).
