Integrated Softswitch

The VP2510 / VP3510 Integrated Softswitch offers a compact, self-contained solution for large scale Class 4 or Class 5 switch replacement or for VoIP service delivery. Based on a combination of selected MetaSphere telephony applications running directly on processor blades in the Universal Media Gateway platform, the Integrated Softswitch is highly cost-effective and exceptionally simple to deploy. 

Modular Scalability

Supporting up to 70,000 subscribers, 112,000 concurrent calls and 250,000 busy hour call attempts the VP series scales to meet the end office and central office demands of the largest carrier networks. A non-blocking native packet switching fabric delivers dual gigabit links to each interface card, and avoids unnecessary VoIP decode/encode operations for maximum voice quality.

With 7RU and 12RU form factors, the VP2510 and VP3510 platforms can be populated with between 6 and 14 Universal Media Cards. Built onto each card is a powerful digital signal processor (DSP) farm sufficient to deliver echo cancellation, announcements, tone detection, silence suppression, and transcoding to every channel. This removes the need for dedicated DSP cards or media servers, simplifying configurations and reducing spares.

Flexibility for Every Application

The VP series supports the widest range of protocols of any media gateway on the market, with comprehensive next generation and legacy capabilities including SIP, MGCP, H.248, AIN, GR-303, CAS, ISDN, MF and ISUP. In addition, the VP2510 and VP3510 can be deployed as a signaling gateway, enabling cost-effective termination of SS7 signaling links anywhere within the network and transport of ISDN signaling messages to the Gateway Control function of MetaSphere, over IP. It even provides a media server function for playing network and service announcements and for mixing multi-way calls.

Future-Proof Open Architecture

Metaswitch preserves your investment by ensuring that our products remain relevant at every stage of your network deployment: from a pre-IMS solution, all the way to a fully realized, distributed IMS core. The VP series functions as ‘IMS in a box’, enabling you to realize the new revenue streams that IMS application servers enable with the simplest possible deployment model. When you’re ready to migrate to full IMS, Metaswitch protects your investment by providing a seamless phased migration path which allows you to repurpose your VP series platform for Media Gateway (MG) or Access Gateway (AG) functionality. 

Carrier-Grade Reliability

The NEBS Level 3-certified VP product portfolio was designed from the outset for 99.999% (“five nines”) system reliability. It achieves this goal through a fully redundant, hot- swappable hardware design, with a combination of 1:1 redundancy for common equipment cards and n:1 protection for all interface cards, power supplies and CPUs, as well as all TDM, and IP interfaces. Even the internal packet bus is powered by two redundant switches. In addition, a sophisticated application-aware software fault tolerance scheme ensures that, in the event of a program logic error, the backup processor takes over control of the chassis ensuring uninterrupted service.

Emergency Standalone

The VP3510 offers the option of Emergency Stand Alone operation, which preserves full switching and service capabilities to all subscribers served, in the event the VP3510 loses IP network connectivity with its media gateway controller.
