Fixed Line SMS Terminal Support (Optional Caller ID card required)

The PBX can relay incoming calls from a Short Message Service (SMS) centre to specific single line telephones (SLTs) that support SMS. Fixed Line SMS is a service that allows text messages to be sent and received via Public Switched Telephone Network (PSTN) access. We recommend using SMS-enabled Panasonic SLTs.

Caller ID Display on SLT (Optional Caller ID card required)

The PBX can receive Caller ID information (telephone numbers and callers' names) from calls received on outside (CO) lines. This information can be shown on the displays of SLTs that support Caller ID as well as proprietary telephones (PTs) when receiving calls.

3-level Automated Attendant (AA)

3-level Automated Attendant (AA) service allows a caller to dial a single-digit number (Direct Inward System Access [DISA] AA number) following the guidance of 3-level DISA outgoing messages (OGMs), and be connected to the desired party automatically.

PC Programming

System programming settings can be accessed using a PC and the Panasonic KX-TEB308 Maintenance Console software as well as by using a PT.

The PBX software can be upgraded via the Serial Interface (RS-232C port) or USB port, using the KX-TEB308 Maintenance Console software.

Quick Setup

Basic PBX parameters such as Automatic Configuration for Outside (CO) Line Type, Country Setting can be programmed the first time the PBX is accessed with a PC using the KX-TEB308 Maintenance Console software.

5.Near devices that generate high frequencies, such as sewing machines or electric welders.

6.On or near computers, telexes, or other office equipment, as well as microwave ovens or air conditioners. (It is preferable not to install the PBX in the same room as the above equipment.)

7.Within 1.8 m of radios and televisions. (Both the PBX and Panasonic proprietary telephones should be at least 1.8 m away from such devices.)

8.Locations where other objects will obstruct the area around the PBX. Be especially careful to leave at least 20 cm of space above and 10 cm to the sides of the PBX for ventilation.

Wiring Precautions

Be sure to follow these instructions when wiring the unit:

1.Do not run unshielded telephone cables near AC power cables, computer cables, AC power sources, etc. When running cables near other noise-generating devices or cables, use shielded telephone cables or shield the telephone cables with metal tubing.

2.If cables are run on the floor, use protectors to prevent the cables from being stepped on. Avoid running cables under carpets.

3.Avoid using the same AC outlet for computers, telexes, and other office equipment, as noise generated by such equipment may hamper system performance or interrupt the system.

22 Installation Manual

2.1 Before Installing

4.Use 2-pair telephone cables when connecting Panasonic proprietary telephones (PTs). Use 1-pair telephone cables when connecting single line telephones (SLTs), data terminals, answering machines, computers, voice processing systems, etc.

5.Unplug the PBX from its power source when wiring, and plug the PBX back in only after all wiring is completed.

6.Mis-wiring may cause the PBX to operate improperly. Refer to Section 2, "Installation" when wiring the PBX.

7.If an extension does not operate properly, disconnect the telephone from the extension line and connect it again, or turn off the PBX using the power switch then turn it on again.

8.For safety purposes this unit is equipped with an earthed plug. If you do not have an earthed outlet, please have one installed. Do not bypass this safety feature by tampering with the plug.

9.Use twisted pair cable for outside (CO) line connection.

10.Outside (CO) lines should be installed with surge protectors. For details, refer to "2.4.1 Connecting Outside (CO) Lines", "2.2.8 Installing Surge Protector".
