Introduction

Overview of the HP SBM

The HP Survivable Branch Communication zl Module (SBM) powered by

Microsoft Lync

is a survivable branch appliance for the Microsoft Lync

Server 2010 solution.

The SBM is installed in an HP 8200 zl Switch Series or HP 5400 zl Switch Series

switch at the branch office. The SBM includes a Windows Server 2008 R2 that

runs as the base OS. Running on this server, is a Lync Server 2010 Front-End

Server that integrates with the main office Standard or Enterprise Lync Server

Pool and handles communication services for up to 1000 users at a branch

office.

The SBM also includes a Lync Server Mediation Server and an HP Media

Gateway, which enable local Lync users to communicate with the public

switched telephone network (PSTN). The SBM connects to the PSTN using

T1, E1, J1, or analog FXO cards that are installed in the module. The module

also supports FXS cards for integrating analog phones or fax machines into

the system.

The SBM also supports SIP trunking for companies that want to use an Internet

telephony service provider (ITSP) to forward external calls rather than a PSTN

carrier. In this case, the SBM routes the external calls to a WAN router that

connects to the ITSP instead of through its own PSTN interfaces.

Finally, the SBM provides survivability; if the WAN connection to the main

office data center fails, the SBM routes all calls over its PSTN connection, so

branch users can still contact both outside telephone numbers and Lync users

within the branch. The SBM automatically detects that the failover and the

restoration of the WAN link without your completing any special configura-

tion.

The SBM is managed through an easy to use Command Line Interface (CLI)

and Web browser interface. The Windows Server 2008 R2 OS running on the

module can also be accessed with Remote Desktop Protocol (RDP).
