Installation & Maintenance Manual 1. Introduction
Version 6.8 15 Microsoft Lync Server
1 Introduction
This document provides step-by-step instructions on installing and configuring the
Survivable Branch Appliance (SBA) application running on AudioCodes Mediant 1000B
OSN, located at the remote branch office and deployed in the Microsoft Lync Server 2013
or 2010 environments. The Mediant 1000B SBA includes an OSN Server platform with
Windows Server 2008 R2 operating system and Mediation Server software installation
(MSI), and a PSTN gateway, all in a single appliance chassis.
In the Lync Server environment, given the centralized deployment model, Unified
Communication (UC) users in a remote site are dependent on the servers in the
enterprise's data center (typically at headquarters) for their communication, and hence are
vulnerable to losing communication capabilities when the WAN is unavailable. Given the
always-available expectation for voice, it is imperative that the UC solution continues to
provide the ability for branch users to make and receive calls when the WAN from the
branch to the primary data center is unavailable.
To provide voice services to branch users during a WAN outage, a branch office
survivability solution–the Survivable Branch Appliance (SBA) application–is hosted on the
OSN Server platform running on AudioCodes Mediant 1000B SBA located at the branch
office. During a WAN connectivity failure, Mediant 1000B SBA maintains call connectivity
among Microsoft users located at the branch office–Lync Server clients (for example,
Microsoft Lync clients) and devices (for example, IP phones)–and between these users
and the public switched telephone network (PSTN).
The AudioCodes Mediant 1000B gateway can also provide the Lync Server environment
with a connection to Analog Devices. The Analog Devices are connected to the Mediant
1000B Foreign eXchange Station (FXS) port interfaces. This document provides also
instructions on how to configure the gateway to use its internal FXS port as Analog
Devices.
