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](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/voice-media/prosbc-freesbc-initial-configuration/README.md) (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. | | Network device name | Purpose | Network device role | Network Config | | voip0 | transcoding port | trans | Tagged 752 (Bonded with voip1) | | | | | | | voip1 | transcoding port | trans | Tagged 752 (Bonded with voip0) | | | | | | | eth0 | control port | ctrl0 | Untagged PVID 750 \*\* | | | | | | | eth1 | control port | ctrl1 | Untagged PVID 751 \*\* | | | | | | | | Configure IP Network for trans | | | | | | | | | \*Create [vp\_trans virtual port](https://github.com/telcobridges-main/tmedia-wiki/tree/main/tmedia/configuration/configuring-a-virtual-port/README.md): \*\***Name**: vp\_trans \*\***Ethernet Ports**: trans \*\***VLAN name**: vlan\_752 \*\***VLAN id**: 752 \*Create [trans IP Address](https://github.com/telcobridges-main/tmedia-wiki/tree/main/tmedia/configuration/configuring-ip-interfaces/README.md): \*\***Name**: trans \*\***Service to use**: RTP \*\***Host VLAN**: vp\_trans:vlan\_752 \*\***IP address**: 192.168.152.1 \*\***Netmask**: 255.255.255.0 | | | | | | | | | | Add transcoding unit | | | | | | | | | | \*Show [transcoding unit](https://github.com/telcobridges-main/tmedia-wiki/tree/main/tmedia/configuration/show-the-hardware-units-menu/README.md) \*Add [TB002177 transcoding unit](https://github.com/telcobridges-main/tmedia-wiki/tree/main/tmedia/configuration/adding-transcoding-unit/README.md) === Transcoding unit network configuration === | | Configure IP Network for voip ports | | | | | | | | \*Modify [voip virtual port](https://github.com/telcobridges-main/tmedia-wiki/tree/main/tmedia/configuration/configuring-a-virtual-port/README.md): \*\***Name**: vp\_voip \*\***Untagged**: unselect \*\***VLAN id**: 752 \*\***Physical Ports**: Use voip0 and voip1 (ctrl-click) \*Modify [voip IP Address](https://github.com/telcobridges-main/tmedia-wiki/tree/main/tmedia/configuration/configuring-voip-interfaces/README.md): \*\***Interface Name**: voip \*\***Service to use**: RTP \*\***Virtual port**: TB002177:vp\_voip \*\***IP address**: 192.168.152.10 \*\***Netmask**: 255.255.255.0 | | | | | | | | | --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://prosbcdocs.telcobridges.com/tmedia-documentation/use-cases/transcoding-unit-configuration-use-case-baremetal-and-virtual-machine.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
