Minacom Unfurls New Functionality

By Cindy Waxer, TMCnet Contributing Editor


Only a week after announcing its newly formed partnership with Tollgrade, a supplier of network service assurance products, Minacom has made news again. The VoIP test solution provider for cable multi-service operators (MSOs) has introduced an addition to its DirectQuality R7 service level test automation platform.
 
This platform has long allowed operators to test VoIP service quality directly to subscriber-installed multimedia terminal adapters (MTAs). However, with this new functionality, the DirectQuality R7 test platform offers test coverage for cable MSOs deploying and managing VoIP services. The Minacom patent-pending MTA loopback testing technique lets operators perform both analog/audio and IP/RTP-based end-to-end VoIP quality tests from PowerProbe service level test probes installed in hubs and/or the network operation center (NOC). IP/RTP loopback testing measures VoIP media streaming performance and quality at the packet level, while analog/audio loopback testing provides true user-perceived speech quality analysis including the impairments audio codes introduce when performing digital/analog and analog/digital speech conversion and compression.
 
The technique is compatible with widely deployed MTAs compatible with data-over-cable service interface specification (DOCSIS) version 2.0 or later, including devices from Arris, Motorola (News - Alert), and other leading manufacturers.
 
In addition to testing VoIP quality within a cable MSO's network, Minacom PowerProbes can conduct loopback tests from the PSTN-side of media gateways and softswitches to fully assess the effects PSTN/IP conversion has on VoIP quality. As most cable VoIP customers regularly place calls outside the MSO's network, testing VoIP as it is delivered to the PSTN is a critical part of most operators' quality assurance test strategies.
 
Minacom's MTA loopback testing method is compatible with PowerProbe software test agents capable of measuring all industry-standard speech quality metrics, including MOS, R-factor, packet loss, jitter, latency, echo, noise, call volume, and DTMF transparency, as well as common network times and call connectivity measurements such as dial-tone delay, post-dial delay, billing-duration and call completion ratio.
 
In addition, loopback testing can also be used to validate Internet / video and data transmission performance.
 
Minacom's DirectQuality R7 test automation solutions are specifically designed to help Telcos and Cable MSO's deploy and maintain VoIP/telephony, IPTV (News - Alert), video, internet, fax and modem services. DirectQuality's web-based OSS interacts seamlessly with legacy operational support systems, integrating service quality into existing business processes including fault management and customer support systems.
