GSO IEC 60728-7-2:2014 Scope
This part of IEC 60728 specifies requirements for The Hybrid Fibre Coax (HFC) Outside Plant
(OSP) Media Access Control (MAC) Layer. This standard is part of the series developed to
support the design and implementation of interoperable management systems for evolving
HFC cable networks. The HMS Media Access Control (MAC) layer specification describes the
messaging and protocols implemented at the Data Link Layer (DLL), layer 2 in the 7 layer
ISO-OSI reference model, that support reliable and efficient communications between HMS
compliant transponders interfacing to managed OSP network elements (NEs) and a
centralized head-end element (HE).
This standard describes the MAC layer protocols that must be implemented between all
Type 2 and Type 3 compliant OSP transponders on the HFC plant and the controlling
equipment in the head-end to support bandwidth management and reliable communications.
Any exceptions to compliance with this standard will be specifically noted herein as
necessary. Refer to Table 1 for a full definition of the type classifications.
Transponder type classifications referenced within the HMS series of standards are defined in
Table 1.
