Panasonic PBX Installation TEA308

The Panasonic KX-TEA 308 is supplied with a full set of documentation that includes Getting Started Guide, Installation Manual, User Guide, Programming Tables and Feature Guide. The notes on this web page are not intended to be a complete installation manual but we hope they will give you a feel for how easy the system is to install.   We will do our best to keep the information up to date but mistakes can happen.  If you see any errors, or would like to make suggestions for improvement, please let us know. Remember - the Panasonic documentation supplied with the system is the only authorised installation guide.

1. System  Construction

The Panasonic KX-TEA 308 system has capacity for 8 extensions and 3 exchange lines. It is capable of supporting Panasonic proprietary phones (Panasonic KX-T7750, 7720, 7730, 7735) and / or single line devices such as ordinary phones, fax and data modems.  This is an excellent system but it is not expandable.  If you are going to require more than 3 lines and 8 extensions we suggest you look at the Panasonic KX-TES824 or the NEC XN120.

2. Wiring the extensions sockets to line jack units (telephone wall sockets).

The initial system is supplied with eight plug-ended extension cords that plug directly into eight sockets (numbered 01 to 08) located on top of the side of the control unit..  The loose end of the cord (no plug) must be terminated to telephone sockets.

The wiring colour code is as follows:

Black  to  pin 3 on socket

Red to pin 5 on socket

Green to 2 on socket

Yellow to  4 on socket

Note:

Pins 2 and 5 are the Voice pair

Pins 3 and 4 are the Data pair

A Panasonic 7730 ( or the earlier 7735) can be used to configure the system if be connected to the first extension jack (marked jack 01).  All proprietary phones ( Panasonic7750, 7720, 7730, 7735,  7050, 7020, 7130) must be connected via a secondary wall socket (2/3A).  All four wires (as shown above) must be connected. 

Ordinary phones can be connected to extension jacks 02 to 08.  For ordinary phones only connect two wires to the telephone sockets,  red to pin 5, and green to pin 2.  These must be connected to a master line jack unit (2/2A). DO NOT connect wires to pins 3 and 4.  You can identify a master socket because you'll see a fairly large capacitor (usually yellow) wired onto the circuit.

Note: Wiring from the control unit to the wall sockets is normally via an MDF (distribution box). We supply a wide range of installation material.

Paralleled connection

An ordinary extension (phone, answering machine etc) can be connected in parallel to a proprietary phone. When an incoming call is received both phones will ring and either can answer the call.

To add an ordinary extension, in parallel to the Proprietary phone, you simply run a lead from pins 2 and 5 of the secondary socket to pins 2 and 5 of the master socket where the ordinary extension will be connected.

3.  Wiring to the exchange lines

In addition to the eight extension cords already mentioned, the system is supplied with three plug-ended extension cords that plug directly into three sockets (numbered CO1 to CO3) located on the top of the system.  The loose end of the cord (no plug) must be terminated to the exchange lines.  If your exchange lines are terminated on a wall socket, you will wire the two wires to pins 2 and 5.

4.  Programming

The Getting Started Guide gives clear instructions as to basic programming  via a KX-T7730 system-phone.  To enter the program mode with a KX-T7730 simply press the programme button followed by * # and your password.  However, one of the interesting aspects of this system is the ability to use a PC to configure the system. Windows based software is supplied with the system.  You simply load the software and connect to your PC via a USB port. The USB lead is not supplied with the system.

Programming Tips...

Auto Attendant message:-

To activate the auto-attendant feature, use your programming software, click on No. 7 (DISA), then 1. (auto-attendant), Tick the box that says 'with auto-attendant. 

To programme your message...Press the program key (using a KX-T7730 or 7735 system-phone), press store key, go off hook, press 9, press 1 (to record) press 1 to 8 (for auto-attendant message number 1 to 8) ,record the message, press store key, message is played back, press program key, go on hook. (ref to page 130 of the User Manual). '

Now you have to tell system what message you want the caller to hear...Use your programming software, click on No. 2 (C.O.), then No. 1 (Line Mode), Under Type click Disa...then in the detail box select which message you want the caller to hear...often you will only need one message, i.e. press one for sales, 2 for technical etc.

Idle Extension Hunting:-

Setting up your extension groups is easy and well documented.  Once set up, the incoming call will 'hunt' for an idle extension within the group.  We've had a few cases where customers have said group hunting works fine with internal calls but external calls fail to hunt within the group.  

To get external calls to hunt correctly the 'line' must be configured to direct the call to 'one' extension that is within the group.  This is called DIL (Direct in Line) mode.  To accomplish this you use your Maintenance Console software...click on CO...settings, and you will see that the first column is titled 'mode'.  Click on the word 'normal' and change to 'DIL'.  Assign any extension number that is within the hunt group.  Presto...the incoming call will now hunt for an idle extension within the group.  If you have any  problems just give us a call.

External Call Diversion:-

Traditional analogue lines cannot reliably support trunk to trunk call forwarding. If it is necessary to divert calls to an external number, such as a mobile or home number, we suggest using the 'BT Divert Calling Feature'. When you order your lines ask for 'Business Divert Lines'...the last we heard BT did not charge extra when these lines were ordered.  However, if you already have lines they may charge £1.75 per month, per line.  If you have this feature, you can select the line and then key in a code to divert calls...i.e. *21*(number to divert to)#.  To turn off the diversion you simply access the line and key #21# .  Be sure to check with your service provider ( BT etc.) for current availability and prices.

Important ... A CE stamp is not proof that the system was manufactured for specific use in the United Kingdom but this can be determined by looking at the product label.  Systems marked KX-TEA308'E' are for the U.K.  If it is not marked with an E, you may have problems with connection to the U.K. network.  Also...the notes on this page may not apply. The Panasonic systems we supply are all E marked and supplied with the standard Panasonic U.K. 12 month warranty.  We do not supply grey imports.
