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
6. Call waiting
7. Call forward
8. Multiparty
9. Call transfer
10. Call barring
11. Fixed number dialling
12. Alternate line services
