Transcoding Unit Configuration

Perequisites ProSBC Host Configuration Network device name Purpose Network device role Network Config mgmt0 Management port mgmt Untagged wan0 SBC port LAN/WAN Tagged 1650 (or other) lan0 SBC port LAN/WAN Tagged 1651 (or other) ctrl0 control port ctrl0 Tagged 750 ctrl1 control port ctrl1 Tagged 751 trans transcoding port LAN/WAN Tagged 752 NOTES: The 'Network device name' for transcoding must be trans. To have redundancy, the trans port bonding (using trans0 and trans1 physical ports) needs to be created at initialization time. For baremetal, the trans port bonding, using trans0 and trans1 physical ports must be bonded at initialization time. You can look here for reference: Initial Configuration (Search for "Bonding") For virtual machines, the virtual ports trans0 and trans1 are bonded in the Hypervisor layer of the virtual machine (optional) and the tran interface is presented to the guest (the ProSBC). Hardware Unit - TB002177 is the TSBC-HW-TRANS unit in the below setup.
