1.3.7 Recommendations 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.Table 2 
Ports: 2 ports
Voice Storage (approximate): 6 h
Custom Services: 100
Message Retention: 1 to 30 days or unlimited
Number of Mailboxes: 62 Subscriber and 2 Manager Mailboxes 
Number of Messages per Mailbox: 100 maximum (programmable)

1.4 DIGITAL INTEGRATION
1.4.1 General
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.
1.4.2 APT 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.
1.4.3 Connection 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.
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.

1.4.4 DPT 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.
1.4.5 Connection 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.
When DPT Integration is activated, a single extension jack provides 2 single-line interfaces at 
a Port on the VPS. For example, when 1 line cord (4 wire) is connected to Port 1 on the VPS, 
2 extensions are provided.

2.1 SAFETY PRECAUTIONS
Please read the following precautions before installing the VPS.
2.1.1 Installation
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.

2.1.2 Wiring
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.
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.

2.3 MOUNTING THE VPS ON THE WALL
The wall where the VPS is to be mounted must be able to support the weight of the VPS. If 
screws other than the ones supplied are used, use the same-sized diameter screws as the 
enclosed ones.
To Mount on a Wooden Wall:
1.
Place the template (included) on the wall to mark the 3 screw positions.
2.Install the 3 screws (included accessories) into the wall.
3.Hook the unit on the screw heads.

2.4 FRAME GROUND CONNECTION
IMPORTANT!!!
Connect the frame of the main unit to the ground.
1.Loosen the screw.
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.
