Abstract
The present disclosure relates to a network port circuit which uses transceiver modules and which function according to various protocols and at various bit rates. The transceiver module having a low bit rate is connected in parallel with all two-wire ports. The transceiver modules which function according to a second network protocol and at a higher data rate are individually assigned to the individual two-wire ports. Independently of the activation of the individual transceiver modules, a voltage source is active for supplying power to the two-wire buses connected to the dual-wire ports.
Claims20
A network protocol circuit for connection of network components that have different network protocols, the network protocol circuit having:
- a first transceiver module that is configured to transmit and receive data with a first data rate according to a first protocol,
- multiple second transceiver modules that are configured to transmit and receive data with a second data rate according to a second protocol, and
- multiple two-wire ports,
- wherein the first transceiver module is commonly assigned to all two-wire ports and wherein exactly one of the second transceiver modules is assigned to each two-wire port.
