CG900-GSM Fixed Wireless Terminal
|
|
|
CG900 GSM Fixed Wireless Terminal, when linked with a normal DTMF (Dual-tone Multi-frequency) telephone set, allows you to connect and communicate flexibly within GSM cellular network coverage. Compared with normal cellular phones, CG900A FWT is much more capable of signal receiving and transmitting; thus effectively utilizing the residual coverage capacity of the present GSM network, expanding network coverage, improving the network usage and ultimately bringing new revenues to GSM cellular network operators.
Features:
Outgoing Calls:
When CG900A FWT has been arranged for working, pick up the handset of a normal DTMF telephone set linked to the terminal, dial your number after hearing the dialing tone. Several seconds later you may hear ringing tone from the called phone or busy tone if the called phone is busy. When in the former situation and when your call is answered, the communication begins.
Incoming Calls:
When someone is calling your number, the normal DTMF telephone set linked to the terminal rings. To answer, pick up the handset; to finish, hang up the handset.
Caller ID:
If your DTMF telephone set has LCD display, you may see the number and know who is calling.
Inverse Polarity Signals:
CG900 GSMFWT, when used for public telephony service, may transmit inverse polarity signals for billing purposes.
Local Network Code Setup:
CG900 GSMFWT is programmable for setup of local network code; thus direct dialing local land phone numbers.
IP Header Setup:
CG900 GSMFWT is programmable for IP header setup. When IP header is set up in the terminal and when you are calling a national long-distance number, you are entitled to IP services automatically if the network offers this kind of service.
SIM Card Locking:
When the terminal is programmed with this feature on, it can only function with the installed SIM card; SIM card other than the locked one cannot work with the terminal while the locked SIM card also cannot with other terminals.
Working Status Indicator:
CG900 GSMFWT has seven green indicator lights and one red indicator light.
