<b>DMG4000 Gateways are integrated systems that perform the Survivable Branch Appliance function.</b>
The Dialogic® 4000 Media Gateways (DMG4000 Gateways) are integrated systems that can provide both local PSTN and voice endpoint connectivity at a branch office premise as well as base-level voice service continuity in the event that the corporate WAN becomes unavailable.
The DMG4000 Gateways are standard rack-mount servers running the Windows Server® 2008 R2 operating system. They support the Survivable Branch Appliance function that is part of the Microsoft® Lync™ Server 2010 for unified communications. The Survivable Branch Appliance function allows branch offices to work effectively even if the WAN connection to the central site is lost. The ability to make voice calls, use email, and hold audio conferences continues to be available.
The Dialogic® 4000 Media Gateways contain field-proven Dialogic® Diva® boards and Dialogic® Diva® SIPcontrol™ Software in addition to the Lync Server with its Survivable Branch Appliance function. These elements are integrated in a rugged 1U rack-mount server featuring a high-performance 64-bit Intel Xeon processor.
The DMG4000 Gateways also offer dual Gigabit Ethernet interfaces for IP network connection, as well as a variety options for interfacing to the PSTN or PBXs, including Analog, ISDN BRI, and E1/T1. In addition, the DMG4000 Gateways can be configured to support up to 120 channels of unified communications traffic.
