Chapter 1: Overview
What is the Tenor AX?
The Tenor AX is a high-density VoiP (Voice over Internet Protocol) H.323/SIP switch that com-
presses and packetizes voice, fax, and modem data and transmits it ver the IP network. Designed for
Enterprises and Service Providers, the Tenor AX gives large businesses with analog voice infrastruc-
ture an easy, cost-effective way to capitalize on the power of Voice over IP (VoIP).
The Tenor AX integrates a gateway, gatekeeper, border element, intelligent call routing, and supports
H.323/SIP and QoS all in one solution. The gateway converts circuit switched calls to VoIP calls,
the gatekeeper performs IP call routing functions, and the border element distributes the call routing
directories throughout the network. Through the FXS port, you can connect a telephone, key system
or PBX; through the FXO port, you can connect to the PSTN (through direct connection to the Cen-
tral Office).

The Tenor AX is available in four series types:
• AXM MultiPath. The AXM MultiPath Switch is mainly intended for symmetrical multipath
applications for typical enterprise applications. The number of FXS (i.e., PBX) ports is equal to
the number of FXO (i.e., PSTN) ports. The number of VoIP channels is half the number of
PSTN channels. Calls are routed between the Phone/FXS, Line/FXO, and IP Network.
• AXT Trunking VoIP Gateway. The AXT Trunking VoIP Gateway is mainly intended for trunk
side connections between the PSTN and VoIP Network. The number of VoIP ports is equal to
the number of FXO ports. Calls can be routed in any direction between any of the ports.
• AXG VoIP Gateway. The AXG VoIP Gateway is mainly intended for applications interfacing
between the PBX and the VoIP network. The number of VoIP channels equals the number of
FXS ports. Calls can be routed in any direction between any of the ports.
• AXE Enterprise VoIP Gateway (plus 2 FXO ports). The AXE VoIP Gateway is mainly
intended for applications interfacing between the PBX and the VoIP network, but it also
includes two FXO ports for autoswitching PSTN backup-up and 911 service provision.
