The G650 Media Gateway features an 8U high, 14-slot chassis that can be installed in industry standard EIA-310 19" , 24" , or 600 mm ETSI open or closed racks. The G650 can accommodate a range of analog, digital, ISDN, and IP ( over the LAN) phone station configurations, with voice transport options over IP, analog, TDM, or ATM. Available dual redundant, load-sharing power supplies with AC/ DC inputs provide enhanced system reliability. For scalability, up to five G650 Media Gateways can be stacked together using a TDM/ LAN cable and a built-in connector in the back of the chassis to form a high-capacity port network.

For call control, the G650 Media Gateway connects to an external S8500 or S8700 Media Server over an IP link using the TN2312BP IP Server Interface ( IPSI) . For mission-critical applications, G650 port networks can be configured for IPSI duplication, which provides fault-tolerant duplicated control paths to the media server. This feature introduces a high-availability option for enterprises with existing mission-critical voice systems that want to migrate to an IP transport solution without compromising system reliability and availability. avaya communications
