TECHNICAL DESCRIPTION

FIXED NETWORK SUPPORTED SERVICES

The F151s supports conventional pulse or DTMF telephone equipment. In addition, the F151s is specially designed for maximum compatibility with most PABX analogue links on the market. The F151s are programmed so that they provide exactly the same characteristics as the fixed network. The line connector in the fixed cellular terminal is electronically and functionally the same as the fixed network telephone plug. The nature of the equipment is “ transparent” in terms of end-users as well as the telephone equipment connected. The self-adapting line level controller and the powerful echo cancellation in the units guarantee excellent quality of speech.

The units also support Automatic Area Code insertion. This function automatically adds the local area code to calls within the same area so that users do not have to bother dialling area codes where they are not required.

GSM NETWORK SUPPORTED SERVICES

The F151s units provide the entire range of services offered by a GSM terminal. This is particularly advantageous for a fixed network-emulating unit, since it can offer much more than a conventional fixed line usually does.

Subscriber services operate from the conventional DTMF device connected to the unit, and therefore all of the information regarding activation and handling is described in detail in the user guide included in the kit.

The following subscriber services can be offered, as long as the network supports them: 1. Call line identification presentation (CLIP)

The units support ETSI presentation standards via DTMF of the call line through the two- wire telephone line. In this way, if an ETSI-complying telephone with a screen is connected, the call number can be displayed, with all of the advantages this adds. When the FD10 adapter is used, the unit also supports caller number presentation in compliance with standards ETSI V23 and BELLCORE.

2. Voice Mail

If there is a message in the user’ s voice mail, the unit will generate a special tone advising the user to dial the voice mail number in order to hear the message.

3. Pre-pay Subscriptions

Pre-pay subscriptions for the F151s units can be used allowing users to control their telephone costs. Pre-payment subscriptions can also be recharged via conventional phones connected to the unit.

4. Short Message Service (SMS)

A PC can be connected to the fixed cellular equipment without the FD10 adapter so that a short message program can be used. When the FD10 is used it is also possible to read short message received on the built-in screen.

In addition, users can use the following, well known, GSM network services:

5.	Call hold	10.	Call barring
6.	Call waiting	11.	Fixed number dialling
7.	Call forward	12.	Alternate line services

8.Multiparty

9.Call transfer
