Sonus Networks has enhanced its session border control (SBC) system to support both IP-to-IP session management and TDM-to-IP capabilities on the same platform.

The enhancement to the NBS-9000 SBC, a software upgrade, will make it easier for operators of TDM networks to migrate to IP services.

The enhancements to the NBS-9000 include improved access SBC functionality. Sonus said it has implemented improved security features to monitor and maintain SLAs with individual devices, especially useful in an access SBC environment.

In addition, there is increased support for industry standards like SIPConnect and SIP-B that enables the NBS-9000 to accommodate diverse SIP implementations from a wide variety of clients, devices and SIP servers.

Other updates include:

• Adverse condition recovery: The NBS-9000 enhances support of network operations and emergency call handling in the event of network outages or adverse network conditions.

• Enhanced call control and routing.

• Higher hardware capacity that permits the NBS-9000 to scale to even greater transcoding densities and call rates.
