Ready the Data Center for an SBM Deployment
Add the Survivable Branch to the Lync Server Topology
this way, you can optimize your system for the lowest-cost and most
efficient communications. In addition, you can create backup routes that
ensure that users can always reach who they need to when they need to.
Remember also to establish valid normalization rules for the branch site.
You can use the global dial plan to dictate these rules, or you can create
a new plan.
See the HP Survivable Branch Communication zl Module powered by

Planning and Design Guide for design considerations.
5. Add the test user accounts (created for the Health Monitoring pool) to
Lync and assign them to the SBM’s pool.
6. It is recommended that you configure Media Bypass for the SBM’s site.
This feature enables Lync users to send their VoIP traffic directly to the
SBM’s Media Gateway (PSTN gateway). The SBM’s Mediation Server still
handles signaling traffic to establish the calls, but it does not have to
process all of the media traffic—potentially eliminating some lag and
dropped packets and increasing the SBM’s potential call load.
You can enable Media Bypass globally or for certain traffic only as
determined by site and region configuration. With the latter option, Media
Bypass automatically applies to calls assigned the same bypass ID as the
PSTN gateway. All subnets associated with a site inherit the site’s bypass
ID. Therefore, to ensure that all branch PSTN calls that are routed through
the SBM use Media Bypass, associate all subnets in the branch LAN,
including the one on which the SBM resides, with the same site.
Planning your regions and sites involves complexities that are beyond the
scope of this guide. Refer to Microsoft planning and deployment guides.
7. Set up a Health Monitoring pool.
The SBM Setup Wizard includes a test that verifies that branch Lync users
can successfully place calls through the PSTN. To generate the test calls,
the SBM draws on the user accounts within its Health Monitoring pool.
You must create a pool for which the identify is the SBM’s FQDN. The pool
also contains the SIP usernames (sip:<sip name>) for two valid Lync users
within the SBM’s pool. Typically, you should specify user accounts specif-
ically created for the test, but you can use any accounts assigned to the
SBM pool.
Note You must use the Lync Server Management Shell to create the Health Moni-
toring pool. The cmdlet is New-CsHealthMonitoringConfiguration.
This is the final pre-deployment task for the CS Administrator.
