As you can see, the company has a Microsoft Lync 2010 solution. Previously,
all branch users registered to the Lync servers at the data center. If there was
a WAN failure, however, this solution left the branch users without phone
service. To protect the branch offices from this problem, the company is
installing two SBMs, one at the Dallas branch and one at the Seattle branch.
This chapter outlines the changes you must make at the data center to
accommodate SBMs at branch offices. It provides the steps required to deploy
the SBMs as well as relevant settings that would typically already be in place.
The instructions focus primarily on the Seattle SBM deployment; however, the
process for the Dallas SBM deployment would be quite similar.
Figure 4-2 shows more details about the example network, including VLANs,
IP addresses, and WAN and LAN connection speeds.
