The Analog Telephone Adapter (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 contains 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 possible, just manually 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
- the phone number allocated to your VoIP adapter is
available all over the world where you have unrestricted access to the
- works great on iDirect satellite equipment, together with a
Lamit 2Pro Server (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).
