Example 4: S87xx with 4 CLANs/MGC-50 with 3 boards, board redundancy,
and outgoing CLAN redundancy
In this example, CLAN1 is chosen as the primary CLAN for the Polycom MGC system to use,
and CLAN2 is a backup. CLAN2 provides backup to CLAN1 for Polycom MGC registration and
incoming and outgoing calls. If Polycom MGC board IP1 fails, IP2 and IP3 will continue to be
able to make incoming and outgoing calls.
Note that the incoming signaling groups for CLAN2 will be out-of-service unless the Polycom
MGC boards are forced to register with CLAN2 in the event that CLAN1 is unavailable.
Note that CLAN3 and CLAN4 are not used. Additional outgoing call capacity could be added by
defining additional outgoing signaling groups between CLAN3 to IP1, IP2, and IP3, and CLAN4
to IP1, IP2, and IP3. Additional incoming call capacity could be added by defining additional
incoming signaling groups between CLAN3 and CLAN4 to boards IP1, IP2, and IP3.
