							INTEGRATING THE VPS WITH PANASONIC KX-T PHONE SYSTEMS
Installation Manual 41
Integration allows the PBX to send certain digits (touchtone) to the VPS, allowing it to 
recognize the status of the extension and take the appropriate action.
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 dialing the PBXs 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 PBXs 
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 Signaling
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 signaling; however, many proprietary telephones cannot. Some PBXs need 
to be programmed to make proprietary sets use touchtone signaling.Table 8

42 Installation Manual
If the PBX does not provide station-to-station touchtone signaling, VPS services and 
features will be limited.
Message Waiting Notification from an SLT
The PBX extensions should light a lamp or receive stutter dial tone when the Message-
Waiting-Lamp-On code is dialed 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 dialed first, followed by a hookswitch flash and then the On 
code. This presents a problem if the extension is answered before the VPS sends the hook-
switch flash.
If the PBX does not provide message waiting notification from an SLT, the VPS can only 
notify mailbox owners by dialing a beeper number or user-assigned extension.
This process slows down VPS performance as it dials the beeper or extension number and 
waits to confirm notification. The beeper or user-assigned extension notification is meant to be 
used for necessity, usually for mailbox owners who are often out of the office (e.g., sales 
people or field representatives). The only other option, without message waiting notification, 
is for mailbox owners to periodically call the VPS to check for messages.
Screened Transfer from an SLT
The PBX must provide a screened transfer from an SLT for the VPS to function properly.
A screened transfer:
1.Puts the caller on hold, usually with a hookswitch flash.
2.Dials the extension.
3.Checks to see if the called subscriber is in, out, or on another line, and whether or not that 
subscriber accepts the transfer.
4.Completes the transfer (by going on-hook) or returns to the caller to say that the party is 
busy or not available. It then gives the caller an opportunity to leave a message. 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 dialed.
TEST: See if dialing the On code from an SLT can turn on an extensions 
message waiting indicator. 
						

							INTEGRATING THE VPS WITH PANASONIC KX-T PHONE SYSTEMS
Installation Manual 43
If the PBX does not provide screened transfer from an SLT, the VPS cannot give callers the 
option to leave a message in a subscribers mailbox.
Follow-on ID or Called Party ID
When forwarding or transferring a call to the VPS, a PBX with Follow-on ID sends the mailbox 
number of the called subscriber to the VPS before connecting the caller. The VPS responds by 
playing that subscribers personal greeting. This operation is sometimes called Call Forward to 
Mailbox. Without this feature, the VPS cannot immediately play the greeting when the line is 
busy or there is no answer and allow the caller to leave a message.TEST: Place an outside call from an SLT. See if you can set up a screened 
transfer to another extension. Next, try the same test with an internal call. 
(The VPS may have to transfer both types of calls.)

3.2 PBX PARAMETERS AND PORT SETTINGS
3.2.1 General Guidelines and Definitions
Optimal performance of the VPS/PBX system relies on proper VPS programming. There are 
3 categories of hardware settings: RS-232C, Port Settings, and PBX Interface Parameters. 
Entering a number sets some of the parameters, while others use sequence codes.
3.2.2 RS-232C Settings
Baud Rate (300-38400): Specifies the speed at which the data is transferred in bits-per-
second.
Word Bit Length (7-8): Defines the number of bits in each byte or character.
Parity (N, O, E): Specifies the parity used for error detection.
Stop Bit Length (1-2): Specifies the number of bits used to signify the end of the byte.
Default: 9600, 8, N, 1
3.2.3 Port Settings
There is no need to change these in a typical installation. Only change these parameters when 
connecting the VPS to a PBX other than a KX-T series PBX. Each port on the VPS should 
match the type of signaling the PBX expects. If you need to change these settings, refer to the 
PBX manual or customer support office to get the correct values for these settings.
Flash Time—100 ms, 300 ms, 600 ms, 900 ms: 
 The minimum length of time that the PBX requires to recognize a hookswitch flash. 
Choose the amount that is equal to or greater than the PBXs setting.
CPC Signal (Calling Party Control Signal)—NONE, 6.5 ms, 150 ms, 300 ms, 450 ms, 
600 ms:
The length of time allowed for the short break in loop current that is used to indicate 
that the caller has hung up; usually set to NONE, since most PBXs do not provide this 
signal to single line ports. If choosing a setting other than NONE, use an amount equal 
to or less than the PBX or telephone company provided CPC signal.
Disconnect Time—1 s-8 s:
The length of time that the line is temporarily unavailable after a call has ended.
Dial Mode—Touchtone, Pulse 10 pps, Pulse 20 pps:
The type of signaling the PBX single line port expects to receive (pps = pulses per 
second).

3.2.4 PBX Interface Parameters
Dialing Parameters
PBX Type:
Specifies the type of PBX which is connected to the VPS.
Integration Mode:
Specifies the method of integration to be used between the VPS and PBX. If PBX type is set 
to the Panasonic KX-T series, the Inband Signaling parameters are set automatically and 
should not be altered. APT Integration is only available when a KX-TA624 PBX is 
connected and the software is upgraded. DPT Integration is only available when a KX-TD 
series or KX-TA1232 PBX is connected and the software is upgraded.
Operator Transfer Sequence:
Tells the VPS how to transfer a call to the operator.
Example: FTX [hookswitch flash—dial tone—dial (operator) extn.]
Extension Transfer Sequence:
Tells the VPS how to transfer a call to an extension.
Example: FTX [hookswitch flash—dial tone—dial extn.]
Alternate Extension (Transfer Sequence): 
Tells the VPS how to transfer a call to an extension that belongs to the Alternate Extension 
Group. This is useful for extensions that need a special transfer procedure (i.e., blind 
transfer) such as modem extensions.
Example: FTXD [hookswitch flash—dial tone—dial extn.—hang up]
Reconnect Sequence on Busy:
Tells the VPS how to return to the caller if the called extension is busy. PBXs differ in how 
they handle this function. Test from an SLT to determine the sequence.Table 10

Reconnect Sequence on No Answer:
Tells the VPS how to return to the caller if the called extension does not answer. PBXs differ 
in how they handle this function. Test from an SLT to determine the sequence.
Reconnect Sequence on Refused Call:
Tells the VPS how to return to the caller if the called extensions owner has enabled Call 
Screening to not take the call. PBXs differ in how they handle this function. Test from an 
SLT to determine the sequence.
Light On Sequence for Message Waiting Lamp:
This is the dialing sequence that the VPS must use to turn on a message waiting lamp at an 
extension.
Light Off Sequence for Message Waiting Lamp:
This is the dialing sequence that the VPS must use to turn off a message waiting lamp at an 
extension.
Call Waiting Sequence:
This sequence is carried out by the VPS to perform call waiting when the called extension 
is busy. PBXs differ in how they handle this function. Test from an SLT to determine the 
sequence.
Release Sequence for Call Waiting:
This sequence is carried out by the VPS to release call waiting. PBXs differ in how they 
handle this function. Test from an SLT to determine the sequence.
Inband Signaling
These parameters are used when the Integration Mode is set to Inband. If the PBX type is set 
to a KX-T series system, these parameters will be automatically set. If another type PBX is 
used, check that systems installation manual for settings.

Digit Translation Table Parameters
These parameters allow PBXs that have a fixed Follow-on ID sequence to be used with the 
VPS. For example, a Follow-on ID sequence of [ 1001] can be changed to [#61001] by 
using these parameters. 
Inter-Digit Time-Out: This parameter defines the interval of incoming signals (Follow-
on ID) from the PBX to the VPS. The Digit Translation Table applies the digits received 
within this time to translation.
Input-Output (up to 8 alphanumeric characters): When the system receives digits 
within the inter-digit time, it checks them against the input table. If they are found, the 
system utilizes the output digits in their place. 7Forwarded to 
Voice Mail (Busy)The extension dialed is forwarded to Voice Mail and no 
other Voice Mail ports are available to accept the call. (This 
signals the Voice Mail port [usually Auto-Attendant] to let 
the caller to leave a message.)
8Forwarded to Extn. The extension dialed is forwarded to another non-Voice 
Mail extension.
9Confirmation Tone The Message Waiting Lamp On or Message Waiting Lamp 
Off code is dialed successfully.
#9Disconnect The caller disconnects. The central office must set a CPC 
signal to the PBX line for this signal to work for outside 
calls.Table 11

3.3.2 KX-T123211D Software Verification and Programming for 
Inband Integration
1.Check the software version of the KX-T123211D by using System Program [98], which 
shows the software version number:Y201Z940430
(TM3)
The underlined digits represent the software production date code (format YYMMDD). In 
this example, the date code is April 30, 1994 (year, month, day). For this software version, 
the software production date of the PBX must be April 30, 1994, or later.
If the software production date of the PBX is earlier than 4/30/94, call National Parts 
Center (1-800-833-9626) to order a software upgrade.
2.Enable System Program [80] for each extension connected to the VPS.
This parameter is used to tell the KX-T123211D which extensions are connected to the 
VPS. Ports with this parameter enabled can receive Follow-on ID and DTMF call status 
signaling (busy, answered, disconnect, etc.) if the Voice Mail integration and DTMF 
integration features are also enabled.
3.Enable System Program [81] to turn on DTMF Integration. On extensions with the Voice 
Mail port parameter enabled, the KX-T123211D can send codes (touchtones) to indicate 
call states; this increases VPS efficiency. Codes apply to all transferred calls; outside calls 
only indicate disconnect (provided the KX-T123211D is programmed for CPC detection 
and the Central Office sends the CPC signal). Refer to the Table 10 in the Section 
3.2.4 PBX Interface Parameters. Call Waiting

4.Put all extensions connected to the VPS into 1 extension group using System Program [60].
Reserve this extension group for these extensions! Do not mix other extensions into this 
group.
5.Enable hunting for the VPS extension group using System Program [08].
6.Set the hunting type for the VPS extension group to circular using System Program [09].
7.At every VPS extension, temporarily connect an SLT or butt set, go off-hook and dial 
7301# to turn on Data Line Security. This prevents the KX-T123211D from sending 
Executive Override or Call Waiting tones to these extensions. We recommend that all 
Voice Mail port extensions have this feature enabled to avoid interruption of recording.
8.At every user’s extension, go off-hook and dial 7192#. This sets the proper Follow-on ID 
sequences so that forwarded calls go directly to the extension’s mailbox. The KX-
T123211D automatically sends the extension’s digits to the Voice Mail port before 
connecting the caller.
For Follow-on ID to work:
Ports connected to the VPS must be assigned as Voice Mail ports.
Extensions must be forwarded to the first port of the Voice Mail (using the Busy/No 
Answer mode or the All Calls mode).
The mailbox number should be the same as the extension number.
Interaction with other features:
Call Forwarding—If the extension is forwarded to an extension that is also 
forwarded, the forwarding will not work.
Call Hunting—Hunting does not interfere with Follow-on ID.
Call Transfer—Calls transferred to an extension with Follow-on ID and call 
forwarding enabled will be forwarded directly to the mailbox.
Data Line Security—We recommend that all Voice Mail port extensions have this 
feature enabled to avoid interruption of recording by Executive Override tone or 
Call Waiting tone.
9.Select the appropriate outside (CO) Line feature settings depending on how your customer 
plans to use the VPS: A) to answer all incoming calls, B) as an operator backup, or C) to 
only answer calls not answered by user extensions.
Recommended outside (CO) line feature settings:
a)If the VPS is answering all incoming calls:
Outside (CO) Line Mode—Use System Programs [51] and [52] to set this 
parameter. Program all lines DIL to the first extension of the Voice Mail hunt group. 
The KX-T123211D will allow incoming CO calls to hunt only if the outside (CO) 
lines are DIL to the first port of the hunt group. Lines programed as Normal do not 
hunt.
