BCM50 capabilities aligned with BCM 4.0

In addition to the new features introduced with BCM50, it incorporates many features that were introduced with BCM 4.0. These include:

•"Proactive Voice Quality Monitoring"

•“Ad-Hoc conferencing” on page 25

•“Meridian Customer Defined Network (MCDN) Trunk Anti-Tromboning (TAT) with integrated applications” on page 25

•“Session Initiated Protocol (SIP) enhancements” on page 25

•“Security enhancements” on page 26

•“Terminal and mobility support” on page 28

Proactive Voice Quality Monitoring

The PVQM capability provides the ability to set call-quality thresholds for IP sets receive an alert and if these thresholds are violated. This provides the ability to proactively identify voice quality of experience (QoE) issues on a per-call basis. This, in turn, enables troubleshooting of voice-quality issues within the network.

PVQM supports calls from an IP set to any other set or trunk. The solution is optimized with Phase 2 IP sets, which support autonotification.

Measured call-quality metrics include:

•packet loss

•inter-arrival jitter

•listening R-value

•RTCP round trip delay

Listener "R" value is a direct measure of the call quality or transmission quality, incorporating the effects of CODEC type, packet loss, discard, burstiness, delay, and other relevant voice-quality metrics.

With PVQM, a system-wide summary view of threshold-violation alert occurrences is maintained. Threshold violations can be sent as alarms and used by the centralized AppManager VoIP performance-monitoring product from NetIQ to generate a system-wide view of the voice quality of the network and help diagnose voice-quality issues. The alarms include extensive call-quality information in accordance with IETF RTCP-XR RFC 3611.

PVQM on BCM50:

•provides the ability to monitor quality and integrity of IP-based voice networking

•ia a a significant differentiator in VoIP convergence network sales with its market-leading, proactive, per-call focus

•mitigates customer issues over whether the data network or the BCM is at fault when call-quality issues situations occur

•provides consistency in QoE solution across Nortel enterprise call servers to facilitate mixed network deployments
