Tollgrade Features Live Demo of VoIP Service Assurance at Cable-Tec EXPO 2006 in Denver
22 June 2006
Tollgrade Communications, Inc. (Nasdaq: TLGD), a leading supplier of network service assurance products for the cable and telecom industries, announced today that the company will perform live VoIP service assurance demos at Booth #593 at SCTE Cable-Tec EXPO 2006, being held this week at the Colorado Convention Center in Denver.

The demonstration includes Cheetah(TM) CMD-P Power Supply Transponders with embedded, PacketCable(TM)-Interoperable VoIP clients, managed under the CheetahXD(TM) Broadband Service Assurance Platform. This solution provides full bi-directional VoIP service quality assessments by originating test calls within a PacketCable network and analyzing a robust suite of performance indicators -- such as delay, loss, jitter, and mean opinion score (MOS). For each test call, near-end results are analyzed locally on the Cheetah DOCSIS(R)-based transponder while far-end results are obtained via an RTCP-XR report.
These VoIP service quality assessments best resemble the true performance of a VoIP call within a PacketCable network by verifying call signaling (including DQoS) and measuring bi-directional voice quality within an asymmetrical DOCSIS channel. Competitive offerings provide only a simple unidirectional RTP loopback test, returning results that are more representative of the customer's high-speed Internet access experience than their VoIP service experience.
Tollgrade's Cheetah DOCSIS-based CMD-E IP Test Point and CMD-P Power Supply Transponders enable cable operators to proactively test the network's ability to transport premium data and VoIP services from the headend to the HFC end-of-line. The CMD family of HFC-based test points allows cable operators to fully measure their customer's VoIP service experience without requiring expensive or complicated tools to be deployed within the customer premise.
The CMD Series of DOCSIS-based Transponders have been awarded PacketCable Release 1.0 "Verified for Interoperability" by CableLabs(R). As a PacketCable device, CMD transponders that are currently widely deployed to monitor power supply status and performance within the HFC network, can now emulate a subscriber's E-MTA. This enables cable operators to "actively sample" VoIP service performance by verifying both VoIP signaling and call quality from an HFC-based test point, where most problems reside.
CheetahXD Broadband Service Assurance Platform provides cable operators with a comprehensive view of the broadband network and services, and offers a complete status monitoring solution for entire HFC network. It also provides detailed analysis of IP service quality, including on-demand testing for VoIP. In conjunction with the CMD Series of DOCSIS-based Transponders, CheetahXD delivers cable operators an accurate view of their customer's VoIP service quality through analysis of key performance indicators such as mean opinion score (MOS), R-factor, jitter, latency and packet loss.
