Hybrid Management Sub-Layer
The SCTE Hybrid Management Sub-Layer refers to a set of specifications intended to support the design and implementation of inter-operable management systems for evolving HFC cable networks.
The HMS Physical Layer Specification describes the physical layer portion of the protocol stack used for communication between HMS-compliant transponders interfacing to manage outside plant network elements and a centralized headend element.
The HMS Media Access Control Layer Specification describes the messaging and protocols implemented at the Data Link Layer, Layer 2 in the 7-layer ISO-OSI reference model, that support reliable and efficient communications between HMS-compliant transponders interfacing to managed outside plant network elements and a centralized headend element.
