The Dialogic 4000 Media Gateway Series (DMG4000 Gateways) is a set of integrated systems designed to connect Microsoft Office Communications Server 2007 to existing PBX systems and PSTN networks. Based on a standard rack-mount server running the Windows Server operating system, the DMG4000 Gateways are "hybrid gateways" designed for the Office Communications Server 2007 role of Mediation Server, which is Microsoft's technology providing PSTN and PBX interoperability, high-fidelity VoIP, and security. The DMG4000 Gateways have a familiar user interface, which minimizes Total Cost of Ownership (TCO) by reducing the need for operational and administrative training and special maintenance. In addition, the DMG4000 Gateways keep the number of devices needed to support Office Communications Server 2007 to a minimum by integrating the Mediation Server into a gateway, reducing hardware maintenance. The DMG4000 Gateways contain field-proven Dialogic Diva boards and Dialogic Diva SIPcontrol Software in addition to Mediation Server software. These elements are integrated in a rugged, compact 1U Intel IP Network Server NSW1U, which features a high-performance 64-bit Dual-Core Intel Xeon processor 5100 series, resulting in a system that can be installed easily in a standard data center rack. The DMG4000 Gateways also offer dual Gigabit Ethernet interfaces for IP network connection, as well as a choice of two or four T1/E1 interfaces to the PSTN or PBX. They can be configured to support up to 120 channels of unified communications traffic between legacy networks and an IP network hosting Office Communications Server 2007.
