Agilent Technologies Inc. has announced the extension of its NgN Analysis System to address the quality assurance needs of cable VoIP service providers. Through the added support for common open policy service (COPS) protocol and for Cedar Point softswitches, the system displays end-to-end call flow records for advanced performance metrics and real-time and historical troubleshooting.
Agilent’s NgN Analysis System correlates COPS protocol with other protocols, such as PacketCable network call signaling, trunking gateway control protocol, SIP and SS7, and provides a single, detailed call record. This enables service providers to drill down to quickly troubleshoot quality of experience problems. For advanced troubleshooting, complete decodes are available for all signaling messages.
Network-wide call correlation is now supported for networks using the Cedar Point Softswitch, associating subscribers’ endpoint addresses with their phone numbers.
“To meet subscribers’ high expectations for service quality, service providers must deploy network monitoring systems that address the nuances of VoIP within the cable infrastructure,” says Bob D’Eletto, marketing manager for Agilent’s OSS division. “NgN Analysis System now enables service providers to see call statistics grouped geographically, indicating whether a problem is associated with an individual subscriber or groups of subscribers using the same fiber group or node.”
