P/N 480-0062-00-10 1-13Chapter 1: OverviewHop-off PBX Calls. Hop-off numbers are phone number patterns for calls to be routed out to thePSTN. (A hop-off PBX call is a toll call which hops through a private network to reduce or elimi-nate the toll charge.) They are entered in a Hop-off Number Directory and associated with trunkswhere matching calls should be sent.Tenor AX supports those hop-off PBX calls where the destination Tenor AX is programmed to routethe call to the PSTN. The destination Tenor AX unit is configured with the phone numbers to be“supported” for this feature.H.323 Gatekeeper ServicesThe Tenor AX unit’s built-in H.323 gatekeeper performs IP call routing functions, such as call con-trol and administrative services to another Tenor AX unit, or another H.323 endpoint. The gate-keeper’s functionality complies with the H.323 industry specifications for voice control andmanagement.Gatekeeper. A Gatekeeper in an H.323 network provides call control services and other services toH.323 endpoints (i.e., gateways, terminals, and MCUs). The Tenor AX has a built-in H.323 gate-keeper which complies to the H.323 industry specifications for voice control and management. Thegatekeeper performs call routing functions for calls entering and exiting a site.The Gatekeeper performs IP call routing functions, such as Call Control Signaling and Call Authori-zation for Gateways, IP phones, and H.323 terminals. The Gatekeeper communicates with otherGatekeepers through a Border Element. When using a group of Tenor AX units, you can assign oneunit as the Gatekeeper for the network. We recommend you configure each as its own gatekeeper.Tenor AX supports gatekeeper to gatekeeper communication using the standard LRQ (LocationRequest)/LCF (Location Confirm) messaging scheme.Zone Management. A zone is a group of H.323 defined endpoints controlled by a Gatekeeper. End-points can be gateways (i.e., Tenor AX), terminals, and/or multipoint conferencing units (MCUs).Endpoints establish control channels with a gatekeeper for registration, admission, and security. Callrouting information about the endpoint is sent to the gatekeeper, including: IP address, unit type(gateway, terminal, or MCU) and routing information (such as phone numbers, number patterns,etc.).A collection of zones is an administrative domain. An administrative domain provides call routingservices for its zones through gatekeeper to gatekeeper messages or gatekeeper to border elementmessages (see below for more information).Call Registration. When registration from an H.323 endpoint is complete and a call is originated,the call request is sent to the gatekeeper. The call request provides the Gatekeeper with the dialednumber and requests the routing information. The gatekeeper confirms the dialed number and sup-plies the endpoint with the destination IP address. For example, a Tenor AX’s gatekeeper will act asthe gatekeeper for that zone and all of the other endpoints will register with it.Border Element. The Tenor AX’s gatekeeper uses a border element to gain access to the routingdatabase of the administrative domain for the purpose of call completion or any other services thatinvolve communications with other endpoints out of the administrative domain. The border elementfunctionality is built into the Tenor AX unit, along with the gateway and gatekeeper.
