Abstract

Physical-layer information is conveyed within a packetized communication network via a timing-modulated side channel to yield low-latency physical interface control without consuming host-layer signaling bandwidth. Multi-modal transceivers at opposite ends of a signaling link optionally communicate to confirm mutual support and signaling headroom for timing-modulated information exchange before transitioning from an in-band feedback mode to a side-channel feedback mode.
