Chapter 1: Overview

PacketSaver™

PacketSaver packet multiplexing technology reduces the amount of IP bandwidth required to support multiple calls flowing between two endpoints. PacketSaver minimizes bandwidth usage by aggregating samples from multiple VoIP conversations and packing them into a larger IP packet with a single IP header. The process removes the need to send a bulky IP header with individual voice packets. As a result, it eliminates the transmission of redundant information.

IVR/RADIUS support

Interactive Voice Response (IVR) is a feature of the Tenor CMS that enables you to offer services, such as Prepaid calling cards and Post-paid accounts, to your customers.

The Tenor CMS uses the RADIUS (Remote Authentication Dial-In User Service), for authenticating and authorizing user access to the VoIP network, including ANI Authentication (Types 1 and 2). The RADIUS is a standard protocol which provides a series of standardized message formats for transmitting and receiving dialed information, account data and authorization codes between the network access gateway and the billing server. As a result, the RADIUS enables the Tenor CMS to interoperate directly with billing server application software from a wide range of vendors. To provide redundancy, the Tenor supports two RADIUS servers: Primary and Secondary.

Easy Connect to Console

Plugging a serial cable (for CPU) or null modem cable (for System Controller) between the System Control- ler/CPU card’s asynchronous RS-232 port and a serial port of your PC, will allow local chassis management. Through the console connection, you are able to assign an IP address. In addition, if you are directly connected to the chassis, you are able to configure that chassis via Command Line Interface (CLI).

H.323 Gatekeeper Call Control Management

The Tenor CMS chassis’s built-in H.323 gatekeeper performs IP call routing functions, such as call control and administrative services to another Tenor CMS unit, or another H.323 endpoint. The gatekeeper’s functionality complies with the H.323 industry specifications for voice control and management. See H.323 Gatekeeper Services, later in this chapter, for more information.
