Information processing systems. Fibre Distributed Data Interface (FDDI) - Hybrid Ring Control (HRC) Ingestion-build-82396 Conditioning of test specimens1 Scope This part of ISO IEC 9314 specifies a hybrid ring control (HRC) protocol which provides a mode of operation in which both packet switched and isochronous data are transmitted within the same special frame structure, called a cycle. HRC is designed to operate with the existing media access control (MAC), physical layer (PHY), and physical medium dependent (PMD) layers of the FDDI protocol. The HRC is composed of the hybrid multiplexer (H MUX)
