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 Skinny Client Control Protocol (SCCP).
The Cisco ATA analog telephone adaptors are handset-to-Ethernet adaptors that 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 10/100BASE-T data port.

The Cisco ATA, which operates with Cisco voice-packet gateways, uses broadband pipes deployed
through 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.

Note
This guide provides information about the SCCP image for the Cisco ATA. The features and functionality
described in this guide do not necessarily pertain to the features and functionality provided by the other
protocol loads available for the Cisco ATA. Each protocol load has its own administrator's guide. If you are
looking for information about the behavior of the Cisco ATA for a protocol other than SCCP, please refer to
the administrator's guide specific to that protocol.

  • Page 2: Overview Of The Skinny Client Control Protocol

    The Skinny Client Control Protocol (SCCP) is the Cisco standard for real-time calls and conferencing over Internet Protocol (IP). With SCCP, Cisco IP Phones can co-exist in an H.323 environment. When a Cisco CallManager is coupled with an H.323 Gatekeeper or an MGCP Call Agent, a Cisco ATA running SCCP interoperates with H.323 terminals on the far end to establish, control and clear audio calls.
