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® SIPcontrolT 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.
