 SIPcontrol
 Software in addition to 
the Lync Server with its Survivable Branch Appliance function. These elements are integrated in a rugged 1U rack-mount server 
featuring a high-performance 64-bit Intel Xeon processor. 
The DMG4000 Gateways also offer dual Gigabit Ethernet interfaces for IP network connection, as well as a variety options for 
interfacing to the PSTN or PBXs, including Analog, ISDN BRI, and E1/T1. In addition, the DMG4000 Gateways can be configured 
to support up to 120 channels of unified communications traffic. 
Survivable Branch Appliance Functionality 
The Survivable Branch Appliance function in the Lync Server included in DMG 4000 Gateways has the following components: 
•   
SIP Registrar and Proxy for normal and failover routing
•   
Mediation Server for communication between Registrar and IP-PSTN Gateway
•   
IP-PSTN Gateways for routing calls to the PSTN as an alternate transport in case of WAN outages or anomalies
The Survivable Branch Appliance function can support up to 1000 users. If a branch office’s WAN connection to a central site 
becomes unavailable, the Survivable Branch Appliance enables branch users to continue to handle outside and inter-site calls via 
the PSTN, make intra-site calls, use voice mail, and connect with audio conferences via the PSTN. 
Enhanced Gateway Functionality 
DMG4000 Gateways can perform as enhanced gateways deployed in central locations along with the full Microsoft
®
 Lync
 Server 
suite, which includes front end servers and mediation server functions. 
Enhanced gateway functionality allows the DMG4000 Gateways to perform as a common gateway platform across an enterprise, 
providing the same architecture and management interfaces in central and branch locations.
Fax Functionality and Third-Party Application Hosting 
In addition to the role of Survivable Branch Appliance for the Lync Server, DMG4000 Gateways can be used as high-density Fax 
over IP (FoIP) gateways, providing up to 120 channels of fax at V.34 (33.6 kbps) speed, depending on the license purchased. 
A DMG4000 Gateway can also host third-party applications written for Windows Server 2008, including fax server and IP-PBX 
software.  A  runtime  version  of  the  ESTOS  Call  Control  Gateway  (ECCG)  is  pre-loaded  on  each  DMG4000  Gateway  with  five 
complimentary seat licenses for trial purposes. When hosted on a DMG4000 Gateway, this third-party application can provide 
remote call control functionality for existing PBX infrastructure (classic, hybrid, or pure VoIP).
