Product description
1.2 OfficeMaster Survivable Branch Appliance (SBA)
With Microsoft Office Communications Server (2007/2007 R2) it was for the first time possible to use a central
installed OCS at a remote branch. This cost-efficient solution had the drawback that in case of a WAN failure the
whole telephony at that specific branch would fail.

Microsoft Lync Server 2010 was the first version that supported remote site telephony even on WAN outages.
Microsoft has defined an appliance type of products containing all functions needed for telephony in a branch of -
fices; therefore called “Survivable Branch Appliance” (SBA). The same holds true for the new Lync Server 2013
which also offers a compatible SBA product.
„OfficeMaster SBA“ is based on high quality industry grade server hardware which runs Windows Server 2008
R2 together with Microsoft branch office components like Registrar and Mediation Server.
A separate PCI-Express card contains the complete media gateway which supports different types of ISDN con -
nections – four basic rate interfaces (BRI) supporting 8 ports and up to 60 channels of E1/T1 primary rate (PRI)
connections. Four analog FXS ports are available through an additional low profile PCIe card. If more ports are
needed, separate external devices can be added. In addition, support for SIP trunks and legacy telephony devices are
available as well. The gateway board is recognized by the hosting server machine as a standard network interface
card – all gateway functions are completely off-loaded from the main CPU.
