Explanation:
Lync Server also introduces the Survivable Branch Appliance (SBA). It is a hardware device that includes a subset of Lync Server capabilities, including a Mediation Server and a gateway. SBA enables users to continue placing and receiving voice calls in a remote branch during a WAN failure. An SBA can be designated as only a primary registrar pool.
