Thank you for purchasing a Panasonic Voice Processing System, Model KX-TVS90.
Please read this manual before installing, customizing, or operating the Voice Processing System.
Thank you for purchasing the Panasonic Model
KX-TVS90 Voice Processing System.
We are confident that it will provide your customer or client with many years of dependable
service.
This Voice Processing System was especially tailored for the American environment. For
example, it can be configured for English, a second language, or a third language:
System prompts—Recorded at the factory in English
User 1 prompts—Record in any language you like
User 2 prompts—Recorded at the factory in Spanish
These prompts guide subscribers and non-subscribers through specific VPS operations.
However, we would like to stress that for outside callers who merely need to be guided to an
extension, a mailbox, or other destinations (e.g., a fax machine), they can be greeted by a
Custom Service. This supports many languages as there are 12 keys on a touchtone phone and
you can record up to 100 Custom Service menus. One twelfth of these menus can be recorded
in one language if you desire. Another twelfth can be recorded in another language, and so on.
Thus callers can be guided entirely in their native languages. For a multi-cultural United States,
Custom Service is a truly powerful feature. Please see "Custom Service" in Appendix
A1SYSTEM FEATURES for more details.
Note
This product is only for connection behind a suitable PBX and should not be connected directly

1VOICE PROCESSING SYSTEM OVERVIEW
1.1WHAT THE VPS CAN AND CANNOT DO............................................................ 14
The VPS handles incoming and outgoing calls. When a call comes in, it answers, forwards to
appropriate extensions, takes and stores messages, and notifies subscribers when messages are
left. Subscribers may send and transfer messages to other subscribers within the system. The
VPS is easy to use, helping callers through the system with step-by-step voice prompts.
Unlike handwritten messages or those left with answering services, VPS messages are
confidential; they are stored in a mailbox and retrieved only with the subscriber's password.
Other advantages of the VPS are clarity and accuracy, which are commonly lacking with
written messages. The messages come directly from the caller, in the caller's own voice. To
further ensure accuracy, the system allows the sender to correct or change messages before
saving them. Messages can be erased or transferred by the recipient.
1.1.2Basic Operations
Greeting Callers:
The VPS greets callers with a prerecorded message that includes directions for leaving and
editing messages. The VPS can list single-digit numbers for each available extension or
mailbox. Callers who know the extension of the person they wish to reach may dial the
extension number at any time. Callers with rotary phones are transferred to a preprogrammed
destination (which is often an operator or the General Delivery Mailbox) to leave a message.
Sending Messages:
Callers can review and edit messages before leaving them in a mailbox. Subscribers can send
messages to an individual or to several mailboxes at once. The message sender can then verify
that the other subscriber has received the message.
Receiving Messages:
There are several different message notification methods that subscribers can use. They can
choose to be notified by message waiting lamp, beeper, or a call from the system to another
line. System programming determines whether a subscriber will be notified each time a
message is left. (Subscribers can choose to receive message notifications differently depending
on the time of day.) Mailbox parameters, which accommodate 5-100 messages, determine the
maximum length of messages. If the system is connected using Digital Integration, subscribers
can press a pre-assigned button to record conversations into their own mailboxes or other
subscribers' mailboxes while talking on the phone. Digital Integration also allows subscribers
to screen messages as they are being left, or intercept them if required.
14Installation Manual
1.1.3VPS Limitations
The VPS does not support:
UCD functions
UCD (Uniform Call Distribution) is a service that distributes calls evenly among extensions;
when all extensions are unavailable, it returns to callers to say that all extensions are busy.
Calls can be forwarded by the VPS to the KX-TD1232/816/308/500 floating number of a UCD
group. The call then rings at the next available phone.
The VPS supports UCD functions with very limited capabilities. Because the incoming call
is forwarded as an intercom path and not a DIL (direct in line), the following items will not
work:
•time table
•overflow function
•DISA message from a DISA card
•IRNA
VOICE PROCESSING SYSTEM OVERVIEW
Integration with the wrong PBX or with certain Key Systems presents limitations to the VPS'
standard functions. We do not recommend these systems for integration with the VPS. The
section 1.3.3Which Phone Systems are Compatible? explains problems with compatibility.
Installation Manual15
VOICE PROCESSING SYSTEM OVERVIEW
1.2SYSTEM ADMINISTRATION,
MANAGEMENT, AND USE
1.2.1System Administration
System Administration is accomplished by the installer using terminal emulation software. It
concerns setting and changing system parameters and diagnosing system problems.
1.2.2System Management
Two system functions are performed by the customer: System Management and Message
Management.
System Management concerns changing system parameters through the System Manager's
Mailbox.
Message Management concerns recording voice prompts through the Message Manager's
Mailbox. These messages include Company Greetings, Company Name, Department Dialing
menu, Custom Service menus, voice labels for System Group Distribution Lists, user prompts,
multilingual selection menu and System Caller Names.
1.2.3Subscriber Use
System users are called subscribers. Subscribers are assigned personal mailboxes which they
can customize. Subscribers can record their names, record personal greetings, set covering
extensions, record questions for an interview mailbox, set the message reception mode, set
incomplete call handling status, set call transfer status, enter Personal Group Distribution Lists,
set the message waiting lamp, and set notification by calling.

Memory Card:
(One/system) Stores the proprietary system program, and the voice prompts (about 30 min
worth); has the capacity to record approximately 6h of messages from callers.
1.3.3Which Phone Systems are Compatible?
We recommend integration with the following Panasonic phone systems:
•Panasonic KX-TA624
•Panasonic KX-TD308
•Panasonic KX-TD1232
•Panasonic KX-TD816
•Panasonic KX-TA1232
•Panasonic KX-TD500
•Panasonic KX-T336
•Panasonic KX-T123211D
We cannot guarantee adequate integration of the VPS with other PBX systems or with Key
Systems. If the customer does not have a recommended Panasonic PBX system, 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.)
•Station to station touchtone signaling
•Message Waiting Notification from an SLT (single-line telephone)
Installation Manual19
VOICE PROCESSING SYSTEM OVERVIEW
•Screened transfer from an SLT
•Message Waiting Notification on proprietary (multi-line) sets (message waiting lamp
accessed by dialing on/off codes)
If the PBX does not have these features, VPS operation will be limited.
See 3.1.4PBX 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 Voice Mail.
Touchtone Integration enables the VPS to recognize 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 KXTA624 or other Panasonic KX-T series digital 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
from and why the call is forwarded, and recognize what the caller wants to do. Some features
are available only with Digital 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 Synchronization with PBX).
1.3.4Installer Equipment and Software Requirements
The installer must have a personal computer or data terminal equipped with terminal
emulation software. We suggest that you use something like HyperTerminal by HILGRAEVE.
Use the personal computer to program the VPS. Terminal emulation software enables the
keyboard to be used as a data entry device.
While both the personal computer and data terminal are working, the personal computer allows
screens to be saved in a file throughout the process. It is often helpful to retrieve these files later
if technical support is needed.

1.3.7Recommendations for System Configuration
General guideline: a ratio of 6/1 (for every 6 lines, 1 port). There are 2 questions to ask when
considering how many ports are desirable:
•Are the ports answering all incoming calls or just forwarded/transferred calls?
•If they are answering incoming calls, how busy are the lines?
The guideline above (6/1) usually works well with moderate traffic. However, this may have
to be modified for heavy traffic. Recommendations are outlined in the following charts.

1.4DIGITAL INTEGRATION
1.4.1General
There are 2 types of Digital Integration: APT Integration and DPT Integration.
APT Integration is available when the VPS is connected to a KX-TA624. DPT Integration is
available when the VPS is connected to a KX-TD or KX-TA1232 digital PBX.
1.4.2APT Integration
To the Panasonic KX-TA624, the VPS ports look like proprietary telephones. The PBX thinks
that the VPS is a proprietary telephone, and the VPS mimics all actions of a proprietary
telephone. Communication between the VPS and the PBX through digital integration requires
the proper software level in the PBX and 4-wire connections for each port. To communicate
between the VPS and the PBX through APT Integration, the PBX and VPS must be
programmed to work together.
VOICE PROCESSING SYSTEM OVERVIEW
1.4.3Connection Example—APT Integration
For example, you can connect jack 7 of the KX-TA624 to Port 1 of the VPS with a 4-wire
connection (see diagram below). This connection creates 1 Voice Mail extension and can only
answer 1 call. This means that a fully-configured 2-port system requires 2 jacks from the PBX.
VPS
KX-TA624
When APT Integration is activated, a single extension jack provides 1 single-line interface at
a Port on the VPS. For example, when 1 line cord (4 wire) is connected to Port 1 on the VPS,
1 extension is provided.

Installation Manual23
VOICE PROCESSING SYSTEM OVERVIEW
1.4.4DPT Integration
To the Panasonic KX-T series PBX that uses DPT Integration, the VPS ports look like digital
extensions. The PBX thinks that the VPS is a digital phone, and the VPS mimics all actions of
a digital set. Another advantage of digital integration is that the 2B+D communication provides
2 VPS ports for each Digital Station port. Communication between the VPS and the PBX
through digital integration requires the proper software level in the PBX and 4-wire
connections for each port. To communicate between the VPS and the PBX through DPT
Integration, the PBX and VPS must be programmed to work together.
1.4.5Connection Example—DPT Integration
For example, you can connect jack 15 of the KX-TD1232 to Port 1 of the VPS with a 4-wire
connection (see diagram below). This connection creates 2 Voice Mail extensions and can
simultaneously answer 2 calls. This means that a fully-configured 2-port system requires only
1 jack from the PBX.
VPS
KX-TD1232
When DPT Integration is activated, a single extension jack provides 2 single-line interfaces at

2.1SAFETY PRECAUTIONS
Please read the following precautions before installing the VPS.
2.1.1Installation
The VPS needs to be mounted on a wall. Improper placement of the system may result in
malfunction, noise, or discoloration. Avoid installing the VPS in the following places:
•in direct sunlight; in hot, cold, or humid places
•in new areas where there are thermal springs, etc. (where sulfuric gas may damage the
equipment or contacts).
•where shocks or vibrations are frequent or strong.
•in dusty places or places where water or oil may come in contact with the unit.
•near high frequency generating devices such as sewing machines, elevators or electric
welders.
•on or near computers, telexes, or other office equipment; near microwave ovens or air
conditioners. (Ideally, the VPS should not be in the room with these items and should be
at least 1.8 m {6 feet} away from televisions.)
Do not obstruct the areas around the PBX and the VPS. Both require space above for cooling
and space on the sides for maintenance and inspection.
26Installation Manual
2.1.2Wiring
•To assure good quality telephone connection, it is recommended new and modifications to
existing installation of customer premise wiring shall use solid twisted pair copper
conductors with minimum 24 gauge that comply with the electrical specifications for
Category 3 wiring as detailed in ANSI/EIA/TIA-570A Building Wiring Standards.
•Do not wire the telephone cable parallel to an AC power source, computer, etc. If cables
are run near those wires, shield them with metal tubing or use shielded cables and ground
the shields.
•Use protectors if running cables on the floor. Avoid running cables under carpets.
•Avoid sharing a 120 V AC power supply for computers, telexes, and other office equipment
with the VPS. Induction noise from such equipment may interrupt the VPS operation.
When making any connections or removing the cover, be sure the power switch is turned off.
When installing telephone wiring, basic safety precautions should always be followed to
reduce the risk of fire, electric shock and injury to persons, including the following:
•Never install telephone wiring during a lightning storm.
•Never install telephone jacks in wet locations unless the jack is specifically designed for
wet locations.
•Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
•Use caution when installing or modifying telephone lines.
INSTALLATION
Note
If you live in an area that can have frequent power failures, we strongly recommend that you
purchase a suitable UPS (uninterruptible power supply) for your VPS (and PBX if needed).
The power rating of your VPS may be found in the specifications.

2. Insert the grounding wire.
3. Tighten the screw.
4. Connect the grounding wire to the ground.
In most of North America, the ground provided by the "Third wire ground" at the commercial
or residential power outlet will be satisfactory. However, in some cases this ground may be
installed incorrectly. Therefore, the following test procedure should be performed.
Test Procedure
1. Obtain a suitable voltmeter and set it for a possible reading of up to 250 V AC.
2. Connect the meter probes between the 2 main AC voltage points on the wall outlet. The
reading obtained should be 108 V AC-132 V AC.
3. Move one of the meter probes to the third prong terminal (GND).
Either the same reading or a reading of 0 V should be obtained.
4. If a reading of 0 V at 1 terminal and a reading of 108 V AC-132 V AC at the other terminal
is not obtained, the outlet is not properly grounded. This condition should be corrected by
a qualified electrician (per article 250 of the National Electrical Code).
5. If a reading of 0 V at 1 terminal and a reading of 108 V AC-132 V AC at the other terminal
is obtained, then set the meter to the "OHMS/RX1" scale, place 1 probe at the GND
Terminal and the other probe at the terminal which gave a reading of 0 V. A reading of less
than 1 should be obtained. If the reading is not obtained, the outlet is not adequately
grounded. See a qualified electrician.
