Advanced Carrier Services Provider Metaswitch Offers Universal Media Gateway

By Susan J. Campbell, TMCnet Contributing Editor

The power of voice – it is the glue that holds all unified communications together and Metaswitch is a driving force in this space. The company provides the Universal Media Gateway (News - Alert), which will enable advanced carrier service providers to meet the growing needs of users throughout the market. 

The company’s Universal Media Gateway (UMG) is designed and optimized specifically for use with MetaSphere applications. This gateway will incorporate with all of the functions necessary to support TDM media and signaling connectivity; in order to drive advanced carrier services across the full spectrum of legacy telephony protocols. 

The UMG is available in two versions. The first, the MG3510, will scale from 672 to 24,192 fully protected concurrent calls. The second, the MG2510, will scale from 384 to 1,920 fully protected concurrent calls. Both versions of this gateway will run on the same software, as they share the same types of common equipment. 

One important focus for this solution is to support all widely-deployed TDM access and trunk network protocols. The Universal Media Gateway also includes an integrated signaling gateway that will handle the transport of SS7 and ISDN signaling messages to the Gateway Control function of MetaSphere over IP. The UMG also delivers the media server function necessary for playing network and service announcements, as well as for mixing multi-way calls. 

To assure advanced carrier services, the UMG offers 1:1 redundancy for common equipment cards, and N:1 redundancy for gateway cards. In an effort to preserve full switching and service capabilities to all subscribers served by the UMG, the gateway offers the option of Emergency Stand Alone operation. In the event the UMG loses IP network connectivity, subscribers will be protected and advanced carrier services will still be delivered.
