M-CMTS Operations Support System Interface

Published by: 2017-01-01 / 2017-01-01 / 37 pages
This specification defines the Network Management requirements to support a Modular Cable Modem Termination
System (M-CMTS™) for headend components compliant to DOCSIS®. The purpose of this document is to define
the management requirements for the M-CMTS architecture that enables an effective operation of the M-CMTS
components.

The M-CMTS architecture separates the traditional CMTS into two parts. The first part is the downstream physical (PHY) component (known as a DOCSIS EQAM) and the second part consists of the IP networking and DOCSIS MAC functions of the CMTS (known as the M-CMTS Core). This separation of a CMTS into EQAM and M-CMTS Core introduces three new protocol interfaces to DOCSIS-compliant headend systems.

  • DOCSIS Timing Interface (DTI): Provides a frequency reference for M-CMTS Core and DOCSIS EQAM via direct connections to a DTI Server.
  • Downstream External PHY Interface (DEPI): Controls the delivery of DOCSIS frames from the M-CMTS Core to the EQAM devices.
  • Edge Resource Management Interface (ERMI): Provides EQAM devices registration and control to the Edge Resource Management device with the purpose of sharing EQAM resources with video systems such as Video on Demand (VoD).

IPCablecom Part 4: Dynamic Quality of Service for the Provision of Real-Time Services over Cable Television Networks Using Cable Modems

Published by: 2016-01-01 / 2016-01-01 / 91 pages
This document addresses requirements for a client device to obtain access to IPCablecom network resources. In particular, it specifies a comprehensive mechanism for a client device to request a specific Quality of Service from the DOCSIS? network. Extensive examples illustrate the use of the specification.

The scope of this specification is to define the QoS Architecture for the “Access” portion of the IPCablecom network, provided to requesting applications on a per-flow basis. The access portion of the network is defined to be between the Multi-media Terminal Adapter (MTA) and the Cable Modem Termination System (CMTS), including the DOCSIS network. The method of QoS allocation over the backbone is unspecified in this document. Interface to the managed IP backbone and issues related to IP multicast are not within the scope of this document. This specification also recognizes that per-flow reservations may be required within the customer premises, and the protocol developed addresses this potential need.

IPCablecom 1.0 Part 2: Audio Codec Requirements for the Provision of Bi-directional Audio Service Over Cable Television Networks Using Cable Modems

Published by: 2016-01-01 / 2016-01-01 / 43 pages
This standard specifies the audio (voice) codes that are to be used in the provisioning of bi-directional audio services over cable television distribution networks using IP technology (i.e., IPCablecom service). The standard also addresses codec options and packetization issues. Specifically, it identifies the audiocodecs necessary to provide the highest quality and the most resource-efficient service delivery to the customer. Additionally, this document describes a suggested methodology for optimal network support for codecs.

Digital Program Insertion-Advertising Systems Interfaces Part 7 – Message Transport

Published by: 2015-01-01 / 2015-01-01 / 48 pages
This document describes the Digital Program Insertion Advertising Systems Interfaces’ transport protocols required for the exchange of messages defined in the individual parts of the SCTE 130 specification.

Note: Security issues surrounding the transport protocols defined herein have been
purposely omitted and are considered outside of the scope of this document.

Drop Amplifiers

Published by: 2016-01-01 / 2016-01-01 / 11 pages
The purpose of this specification is to recommend mechanical and electrical standards for broadband radio frequency (RF) devices whose primary purpose is to amplify signals presented to an input port and deliver the amplified signals to one or more output ports. The devices are also required to pass signals in a different range of frequencies in the return direction and, optionally, may provide

amplification of such return signals. The specification’s scope is limited to 75ohm devices whose ports are provided with F connectors. The most common use for such devices is on-premises RF signal distribution.

IPCablecom 1.0 Part 9: Event Message Requirements

Published by: 2016-01-01 / 2016-01-01 / 82 pages
The scope of this document encompasses the definition of the Event Message architecture; the services for which Event Messages are defined; the set of Event Messages defined for each supported service; the format and coding of the Event Messages; and finally the transport protocol used to pass Event Messages between IPCablecom network elements.

The Event Messages are designed to be flexible and extensible in order to support new and innovative IPCablecom and value-added services. In an effort to describe some of these features and possible uses of these Event Messages, this document may describe interfaces and signaling protocols that are outside the scope of IPCablecom 1.0. It should be understood that the primary purpose of this document is to support the IPCablecom 1.x architecture and the IPCablecom 1.0 services as defined in this document.

In order to support early deployment of IPCablecom networks, the IPCablecom project is developing specifications in a phased approach. In an effort to keep pace with the larger IPCablecom project and interface specification development effort, the Event Messages are also addressed in a phased approach. Possible future extensions to this document may include topics such as expanded support for fraud detection and other back office applications.

From time to time this document refers to the voice communications capabilities of an IPCablecom network in terms of “IP Telephony.” The legal/regulatory classification of IP-based voice communications provided over cable networks and otherwise, and the legal/regulatory obligations, if any, borne by providers of such voice communications, are not yet fully defined by appropriate legal and regulatory authorities. Nothing in this document is addressed to, or intended to affect, those issues. In particular, while this document uses standard terms such as “call,” “call signaling,” “telephony,” etc., it should be recalled that while an IPCablecom network performs activities analogous to these PSTN functions, the manner by which it does so differs considerably from the manner in which they are performed in the PSTN by telecommunications carriers, and that these differences may be significant for legal/regulatory purposes. Moreover, while reference is made here to “IP Telephony,” it should be recognized that this term embraces a number of different technologies and network architecture, each with different potential associated legal/regulatory obligations. No particular legal/regulatory consequences are assumed or implied by the use of this term.

Digital Multiprogram Distribution by Satellite

Published by: 2016-01-01 / 2016-01-01 / 35 pages
Satellite Digital TV systems have shown their advantages with respect to the analog TV allowing a more efficient use of the satellite frequency spectrum available and establishing a more robust scenario with respect to interference protection.

With the aim to promote the convergence on a worldwide standard for satellite digital multi-program reception systems for television, sound and data services, the systems for the reception of Digital Multiprogram Distribution by Satellite are described. These descriptions configure the universal elements of the satellite Integrated Receiver Decoder (IRD).

The universal elements of the satellite IRD are capable of receiving emissions from System I, and System II.

The common and specific elements of each system have been analyzed and it has been concluded on the feasibility of the implementation of the universal elements of a Satellite IRD. This document analyses the common elements among existing systems, defines and describes the functions of a generic system model and identifies the processes and the minimum set of parameters of the various sub-systems of the universal elements of a Satellite IRD.

The feasibility of the implementation of the common elements in a satellite IRD has been demonstrated in consultation with the industry.
