Dialogic® Media-Gateways |
|
|
|
|
Dialogics IP-Media-Gateways beinhalten eine Palette von Lösungen, welche die Anbindung von neuesten IP-Netzen (SIP) an die traditionelle PSTN-Technologie ermöglichen.
Die Dialogics IP-Media-Gateways wurden entsprechend den Spezifikationen von Microsoft entwickelt, um zum Beispiel die Sprachfunktion zur Mail- und Terminverwaltung im MS Exchange 2007 zu nutzen. Ferner sind sie Microsoft-zertifiziert zur Integration des MS Office-Communications-Server 2007 in die bestehende TK-Anlagen-Infrastruktur.
Die Produktfamilie bietet daher eine ausgezeichnete Lösung für die Anbindung dieser neuen MS Unified-Communications-Produkte an unterschiedlichste TK-Anlagen-Systeme über die Analog-, Q.SIG-, ISDN-S0-Bus- (BRI) oder ISDN-S2M- (PRI) Schnittstelle. Neben bester Sprachqualität einschliesslich Echo-Cancellation bietet das Produkt T.38 Highspeed-Fax-over-IP mit bis zu 33,6 Kbp. |

Dialogic® 4000 Media Gateway Series |
|
|
|
|
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. |
