The Analog Telephone Adaptor (ATA)
The Analogue Telephone Adapter is a phone-to-Ethernet adapter which
allows ordinary (analog) telephone devices to be used via Voice Over
IP (VoIP) services and equipment. The adapter is almost the same size
as a home Internet router and contain more traditional RJ-11 phone jack
ports, one or two for the telephones and another one for the normal
PSTN line. The analog phone plugs into the adapter, which then communicates
with an Internet VoIP Server via an Ethernet connection (RJ-45 ethernet
port connected to a network switch/server/router) using the Session
Initiation Protocol (SIP - an Internet Engineering Task Force - IETF
- standard protocol for initiating an interactive user session that
involves multimedia elements such as video, voice, chat, gaming, and
virtual reality).
The Analogue Telephone Adapters (ATA), are the perfect alternative
to an expensive IP phone.
How does it work?
You plug your wired or cordless phone (or even a fax machine) into
one of the ATA`s RJ-11 jacks using ordinary phone wire. A UTP Cat 5e
cable connects the ATA to the LAN or directly to the Internet (via Ethernet
RJ-45 port), make sure you have a DHCP enabled server in your network
(if that is not possbile, just manualy set the ATA`s IP address and
Subnet Mask from the voice console or connecting it to a computer).
You can either choose from the two Voice over IP phone lines
and one PSTN line adapter (3x RJ-11 jack ports and 1x RJ-45 port) or
for the one Voice over IP phone line and one standard
PSTN line with a network router incorporated adapter (2x RJ-11 jack ports and 2x RJ-45 ports).
Advantages:
- the phone number alocated to your VoIP adapter is
available all over the world where you have unrestricted access to the
Internet.
- works great on iDirect satellite equipment, together with an UDgateway
(both supporting QoS* and IP accelerating technologies.
- together with a VSAT equipment are the perfect solution for Internet
and Telephony requirements in extreme locations (middle of the desert
or on the top of a mountain, for example).
