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 trans-

mission of redundant information.

Conventional VoIP Transmission Sends Many Redundant Packet Headers

Tenor CMS

Tenor using PacketSaver to Minimize Bandwidth Usage

Interactive Voice Response (IVR) is a feature of the Tenor CMS that enables you to offer services, such as Pre-

paid 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: Pri-

mary and Secondary.

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 con-

nected to the chassis, you are able to configure that chassis via Command Line Interface (CLI).

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 function-

ality complies with the H.323 industry specifications for voice control and management. See H.323 Gate-

keeper Services, later in this chapter, for more information.
