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.
