vcon.s media xchange manager↑tm (mxm) provides various system management and supplementary ip telephony services, for helping maintain an enterprise-wide video-over-ip network. the mxm consists of a server, gatekeeper and administrator console. the mxm provides :

    h.323 ■ admission control - controls login and

    gatekeeper registration and providing status information about

    functions endpoints that attempt to log in.

    ■ address translation - converts user numbers,

    h.323 aliases and ip addresses into internal

    directory numbers and the other way around.

    ■ auto-discovery - detects endpoints that try to

    register.

    status ■ node monitoring - provides identification,

    monitoring bandwidth, and connection information.

    ■ registration & login status - identifies the node

    attempting to register, its type and status of the

    login attempt.

    ■ events log - records informational events, such as

    system turn-on, login failure and node

    disconnection.

    bandwidth ■ system - controls the usage of bandwidth until the

    management maximum permitted limit, and the maximum

    number of simultaneous sessions.

    ■ per endpoint/resource usage - controls the usage

    of bandwidth within minimum and maximum

    permitted limits, allocates default bandwidth, and

    permits a maximum number of simultaneous

    sessions.

    ■ multicast sessions - controls and allocates

    available bandwidth during interactive multicast

    videoconferences.

    exchange ■ dialing numbers - automatically or manually

    administration assigns internal dialing numbers

    ■ hunting groups - administrator assigns endpoints

    within hunting groups and defines search methods.

    ■ remote endpoint configuration - administrator

    may change endpoint properties from a remote

    console.

    online directory ■ lightweight directory access protocol (ldap) -

    services supports the use of centralized endpoint directories.

    ■ internet locator server (ils) - provides updated

    endpoint directories. includes the ability to select

    an entry in order to dial.

    ■ microsoft exchange - regularly updated endpoint

    directories, whose entries may be viewed only.

    reporting ■ events - maintains a history log of events of

    various severity levels for customized periods of

    time.

    ■ call accounting - creates a call detail record

    (cdr) of each successful call, therefore enabling

    monitoring and analysis of video traffic.

    ip telephony ■ call forward - required action if endpoint does

    services not answer, or is busy, or for all incoming calls

    (unconditional).

    ■ call transfer - transferring a connected call to

    another endpoint.

    ■ call pickup - enabling other endpoints to answer a

    call intended for a particular endpoint.

    ■ simplified gateway dialing - eliminates the need

    to dial special prefixes and suffixes, and chooses a

    gateway according to requested services and

    availability.
