DMG4120DTI - 4-port T1/E1 (96/120 channels)
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 2003 R2 operating system, the Dialogic® 4000 Media Gateways are basic hybrid media gateways designed for the Office Communications Server 2007 and therefore include the role of Mediation Server, which is Microsoft’s technology providing PSTN and PBX interoperability, high-fidelity VoIP, and security.
The Dialogic® 4000 Media 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 Dialogic® 4000 Media 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 Dialogic® 4000 Media 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.
