H.323 Overview

H.323 is the International Telecommunication Union (ITU) standard for transmitting voice, video, and data across an IP network. Like other VoIP protocols, the H.323 standard is designed to address the functions of signaling and session management from within a packet telephony network. Signaling allows call information to be carried across network boundaries. Session management provides the ability to control the attributes of an end-to-end call. The H.323 standard includes support for call signaling and control, multimedia transport and control, and bandwidth control for both point-to-point and point-to-multipoint conferences.

The H.323 standard includes the following protocols:

• Call signaling using the H.225 protocol

• Media control using the H.245 protocol

• G.711, G.722, G.723, G.728, and G.729 audio codecs

• H.261 and H.263 video codecs

• Data sharing using the T.120 protocol

• Real-time transport protocol (RTP) and RTP Control Protocol (RTCP) for media transport

Chapter 1 Cisco Analog Telephone Adaptor Overview

Components that the H.323 standard employs include a system of interconnected voice terminals, gateways, gatekeepers, multipoint control units (MCUs), and proxy servers. Voice terminals provide point-to-point and point-to-multipoint conference capability for audio, video, and data. Voice gateways interconnect the packetized IP network to the PSTN or ISDN network. Gatekeepers provide admission control and address translation services for H.323 voice terminals and gateways. MCUs enable two or more gateways to engage in point-to-point or point-to-multipoint audio or video conferences.

This section contains descriptions of the following H.323 components:

• H.323 Terminals, page 1-3

• H.323 Gateways, page 1-3

• H.323 Gatekeepers, page 1-4

H.323 Terminals

Voice terminals in an H.323 network must feature system control units, media transmission capabilities, audio codecs, and network interfaces suitable for transmitting and receiving packetized data.

H.323 Gateways

H.323 gateways feature a mixture of characteristics of both standard Switched Circuit Network (SCN) access points and H.323 access points. Gateways perform the translation of audio, video, and data transmission formats as well as interacting with communications systems and various protocols. A primary responsibility of an H.323 gateway is the call setup and teardown necessary to complete a call to and from a packetized IP network and a standard switched network.

H.323 Overview

H.323 Gatekeepers

Gatekeepers are primarily responsible for pre-call and call-level control services for H.323 gateways. Gatekeepers are an optional component in an H.323 system. However, if present, gatekeepers must perform the following call setup and management services:

• Address translation for IP addresses originating from H.323 aliases (for example,

address_pool@cisco.com, for example) or E.164 addresses (for example, standard telephone numbers)

• Admissions control for authorizing or rejecting access to H.323

• Bandwidth control for gateway bandwidth requirements

• Zone management for registered voice terminals, gateways and MCUs

When used in an H.323 system, gatekeepers can also (but are not required to) provide the following functionality:

• Call control signaling using the gatekeeper Routed Call Signaling model

• Call authorization to restrict access to certain voice terminals or gateways, or to restrict access based

on time-of-day criteria

Chapter 1 Cisco Analog Telephone Adaptor Overview

• Bandwidth management for the H.323 system that will enable the gateway to restrict access when

requested bandwidth is unavailable

• Call management including maintaining a list of active calls to indicate available and unavailable

voice terminals and gateways

H.323 MCUs

MCUs are endpoints in an H.323 network that support point-to-multipoint conferences and consist of a multipoint controller and at least one multipoint processor responsible for receiving voice, video, and data streams. These streams are distributed to access points participating in a point-to-multipoint conference.

H.323 Proxy Server

An H.323 proxy server is a proxy specifically designed for the H.323 protocol and examines packets between two communicating applications. Proxies can determine the destination of a call and perform call-connection steps, if necessary.

H.323 proxies perform the following key functions:

• Allow voice terminals that do not support Resource Reservation Protocol (RSVP) to connect to the

proxy through remote access or local area networks with relatively reliable quality of service (QoS). Pairs of proxies can then be employed to develop tunnels across the IP network.

• Support routing of H.323 traffic that is separate from ordinary data traffic by using

application-specific routing (ASR).

1-4

• Enable H.323 to be deployed in networks that use private address space.

• Ensure network security by configuring the proxy server to allow only H.323 traffic over the

network.

Fax Services

The Cisco ATA supports two modes of fax services, in which fax signals are transmitted using the G.711 codec:

• Fax pass-through mode—Receiver-side Called Station Identification (CED) tone detection with

automatic G.711A-law or G.711µ-law switching.

• Fax mode—The Cisco ATA is configured as a G.711-only device.

How you set Cisco ATA fax parameters depends on what network gateways are being used. You may need to modify the default fax parameter values (see Chapter 7, “Configuring and Debugging Fax

Services”).

Note Success of fax transmission depends on network conditions and fax modem response to these conditions.

The network must have reasonably low network jitter, network delay, and packet loss rate.

Supplementary Services
