Abstract
Disclosed herein are systems and techniques for auxiliary master and/or auxiliary call support functionality. For example, in some embodiments, a communication system with auxiliary master functionality may include a master node coupled to a plurality of downstream slave nodes, wherein at least one of the slave nodes may perform master node functions when the master node is disconnected from the system.

An apparatus with auxiliary master functionality in a communication system, comprising:
- a node transceiver, wherein the node transceiver includes upstream transceiver circuitry to receive a signal transmitted over two upstream wires of a two-wire bus from an upstream master node transceiver and downstream transceiver circuitry to receive a signal transmitted over two downstream wires of the two-wire bus from a downstream slave node transceiver, wherein the node transceiver is to selectively operate as a slave or a master;
- and
- a processing device communicatively coupled to the node transceiver, wherein the processing device is to provide a signal to the node transceiver to cause the node transceiver to operate as a slave or as a master, and the processing device is to configure itself as a host for the communication system when the node transceiver operates as a master.
An apparatus with auxiliary master functionality in a communication system, comprising:
- a slave node transceiver, wherein the slave node transceiver includes upstream transceiver circuitry to receive a signal transmitted over two upstream wires of a two-wire bus from an upstream master node transceiver, and wherein the master node transceiver is coupled to a host device for the communication system;
- and
- a processing device communicatively coupled to the slave node transceiver, wherein the processing device is to detect whether communication between the slave node transceiver and the master node transceiver is operational and, when communication is not operational, cause the slave node transceiver to act as an auxiliary master and cause the processing device to act as an auxiliary host.
A method of operating as an auxiliary master in a daisy-chained two-wire communication system, comprising:
- receiving, by a processing device coupled to a slave node, an indication that a master node of the daisy-chained two-wire communication system has disconnected;
- in response to the indication, causing, by the processing device, the slave node to perform master functions for an auxiliary portion of the daisy-chained two-wire communication system;
- and
- in response to the indication, causing, by the processing device, the processing device to perform host functions for the auxiliary portion of the two-wire communication system.
