The SCTE has approved six DOCSIS-based standards around modular CMTS and headend technologies.

SCTE 137-2 2017, "Modular Head End Architecture Part 2: M-CMTS Downstream External PHY Interface," is part of the DOCSIS family of specifications, and in particular, is part of a series of specifications that define a modular cable modem termination system (M-CMTS) architecture for headend components that comply with DOCSIS. The specification includes contributions by operators and vendors from North America, Europe, and other regions.

SCTE 137-3 2017, "Modular Headend Architecture Part 3: M-CMTS Operations Support System Interface," defines the network management requirements to support an M-CMTS for headend components compliant to DOCSIS. The purpose of the document is to define the management requirements for the M-CMTS architecture that enables effective operation of the M-CMTS components.

SCTE 137-4 2017, "Edge Resource Manager Interface for Modular Cable Modem Termination Systems," specifies interfaces used by edge QAM devices, edge resource managers (ERMs) and M-CMTS cores within the context of an M-CMTS.

SCTE 137-5 2017, "Modular Headend Architecture Part 5: Edge QAM Provisioning and Management Interface," is a component of the modular headend architecture; in particular it defines the provisioning and management requirements for the edge QAM device.

SCTE 137-6 2017, "Modular Headend Architecture Part 6: Edge QAM Video Stream Interface," is a component of the modular headend architecture. In particular, it defines the data plane requirements for receiving, processing and transmitting MPEG transport streams in edge QAMs, compliant with the video edge QAM or universal edge QAM profiles described in the architectural overview of the modular headend architecture.

SCTE 137-7 2017, "Modular Headend Architecture Part 7: EQAM Architectural Overview Technical Report," is intended to provide an introduction to the modular headend architecture, with particular emphasis on the edge QAM as a key component. The document describes the various architectural entities and the interfaces that connect them, provides an overview of the various profiles of edge QAM devices and their operations, and discusses the various specifications that contain normative requirements pertaining to the modular headend architecture.
