Cisco Analog Telephone Adaptor Overview
This section describes the hardware and software features of the Cisco Analog Telephone Adaptor
(Cisco ATA) and includes a brief overview of the Media Gateway Control Protocol (MGCP).
Cisco ATA analog telephone adaptors are handset-to-Ethernet adaptors which allow regular analog
telephones to operate on IP-based telephony networks. Cisco ATAs support two voice ports, each with
an independent telephone number. The Cisco ATA 188 also has an RJ-45 10/100 BASE-T data port.

The Cisco ATA, which operates with Cisco voice-packet gateways, makes use of broadband pipes that
are deployed by means of a digital subscriber line (DSL), fixed wireless cable modem, and other Ethernet
connections.
The term Cisco ATA refers to both the Cisco ATA 186 and the Cisco ATA 188, unless otherwise stated.
