Chapter 1: Overview
What is the Tenor DX?
The Tenor DX is a high-density VoIP (Voice over Internet Protocol) H.323/SIP switch that converts
voice, fax, and modem data on digital circuit switched trunks, and transmits it over the IP network.
The Tenor DX integrates a gateway, gatekeeper, border element, intelligent call routing, and sup-
ports 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.
With its MultiPath architecture, the Tenor DX can intelligently route calls between the PBX, the
PSTN, and the IP network to achieve the best combination of cost and quality. It can also route calls
over IP to reduce costs, and then transparently “hop off” to the PSTN, to reach off-net locations.

Tenor DX VoIP Switch
The Tenor DX is available in two configuration types:
MultiPath Switch (intended for PBX and PSTN connectivity)
Gateway (intended for VoIP and PSTN trunk port connectivity).
The MultiPath Switch is mainly intended for symmetrical multipath applications. The number of
VoIP channels is equal to half the number of PSTN channels.The MultiPath Switch configuration
enables connectivity between the customer equipment (i.e., PBX), PSTN and VoIP Network. The
Gateway is mainly intended for trunking applications interfacing between the VoIP network and the
circuit switched network (PSTN). The number of VoIP channels equals the number of PSTN chan-
nels.
Whichever configuration you choose, the high performance unit provides two 10/100 BaseT con-
nections and one RS-232 serial console port connection. The unit also incorporates an intelligent
call routing engine which regulates system resources and configuration while coordinating all voice
traffic activity in the unit.
The Tenor DX may be managed by the Tenor Configuration Manager and Tenor Monitor. Through
the Configuration Manager, you can configure all options, such as signaling data, trunk groups, dial
plans, and call routing numbers. An easy-to-use Java-based installation process enables you to an
install the manager and start configuring within minutes. Through the Tenor Monitor, you can mon-
itor the health of the system, including alarms, call detail records, etc. Both the Configuration Man-
ager and Tenor Monitor provide comprehensive on-line help systems that are available at your
fingertips.
