SOYO G1681 Analog Telephone Adapter User Guide
-2-
Introduction
SOYO G1681 ATA (Analog Telephone Adapter) is an advanced Internet
Protocol (IP) device, allowing its users to experience superb voice
communications over the Internet. Simply plug in your telephone set (regular
phone or cordless phone) to the ATA, and then you will be able to use the
Internet to make phone calls. G1681 ATA works as a standalone device (no PC
is needed) with any broadband Internet connection. This Internet connection
can be either:
A Digital Subscriber Line (DSL) Internet service from a telephone company
A cable modem Internet service from a cable television company
Other high-speed Internet connection such as ISDN and T1
With SOYO G1681 ATA, you can use the same telephone set for your existing
PSTN service and VoIP service. This function is called “dual mode”. If you
choose to use “ip first”, all the calls will be send through VoIP, unless you press
a prefix number to select the PSTN. If you choose to use “pstn first”, all the
calls will be sent through PSTN, unless you press the “flash” button (or hit the
hook switch of the phone once) to select the VoIP. Or you can select to
“disable” the “dual mode” to use the ATA with VoIP only.
Note:
PSTN stands for Public Switched Telephone Network, which refers
to the international telephone system based on copper wires carrying
analog voice data. It is the standard telephone service that most homes
use.
Note:
VoIP stands for Voice over Internet Protocol, a category of hardware
and software that enables people to use the Internet as the transmission
medium for telephone calls by sending voice data in packets using IP
rather than by traditional circuit transmissions of the PSTN.
