Wavelength-Division Multiplex Small Form Factor Pluggable (PXFP-WDM) Optical Transmitter Module Interface Specification

Published by: 2016-01-01 / 2016-01-01 / 27 pages
Many service provider networks are fiber constrained. The cost of fiber construction is prohibitive in most applications and many service provider systems have link distances that significantly exceed 20 km. The use of a PON Extender architecture utilizing WDM optics enables multiple 10G PON links to be deployed on different wavelengths over a single fiber at distances much greater than 20 km.

WDM pluggable optics compatible with PON OLT line cards enable a multi-wavelength link between the OLT platform and a PON Repeater. This standard defines these optics for use in PON OLTs.

Field Strength & Calculation of LTE User Equipment Field Strength

Published by: 2015-01-01 / 2015-01-01 / 13 pages
In late 2010, a new wireless technology called long term evolution (LTE) was introduced in the
United States. LTE service operates in several frequency bands, including the 698 MHz to 806
MHz band, which overlaps the frequency spectrum used by many cable operators to deliver
services to their customers. As LTE service providers continue to deploy LTE service, the radio
frequency (RF) signal emanating from LTE user equipment (UE) represents another source of
potential interference to services carried on cable systems.

This operational practice provides a tutorial on RF signal field strength and a method for
calculating field strength emanating from LTE UE.

Cable Operator Location Risk Assessment Operational Practice

Published by: 2016-01-01 / 2016-01-01
A location risk assessment (LRA) is performed to identify threats that could negatively impact the ability
to conduct business in a geographic location. The results of the LRA help to align strategic business
decisions with effective risk reduction solutions at a geographic location. The LRA considers all threats
whether they are financial, natural, political or human related. The LRA identifies and weighs the risks to
business continuity based on a four-step process.

Multimedia Application and Service Part 2: IPCablecom Multimedia Web Services

Published by: 2017-01-01 / 2017-01-01 / 84 pages
This specification provides a simple, open interface between a generic Application Server (AS) and an IPCablecom Multimedia Application Manager (AM). Specifically, this specification defines a common Web Service (WS) interface to the IPCablecom Multimedia Application Manager (AM) that enables an AS to dynamically request network resources on the cable operator’s access network. The primary goal of this interface is to allow AS developers to rapidly create new applications in shorter timeframes and without having a deep knowledge of the cable operator’s access technology. This interface is based on the SOAP/eXtensible Markup Language (SOAP/XML).

Alternative Energy, Taxes, Incentives, and Policy Reference Document

Published by: 2015-01-01 / 2015-01-01 / 43 pages
This document provides cable operators with references and resources to evaluate
alternative energy technology options based on a given geographic location, facility type,
and existing or planned infrastructure. It functions as a selection tool to aid in describing
various alternative energy technologies by recognizing which resources would have the
greatest impact on reducing energy costs, electrical grid dependency and environmental
impact, as well as improving system reliability and mitigating climate change risks.

DOCSIS 3.1 Part 2: MAC and Upper Layer Protocols Interface [Input]

Published by: 2016-01-01 / 2016-01-01 / 773 pages
This standard is part of the DOCSIS® family of specifications. In particular, this specification is part of a series of
specifications that defines the fifth generation of high-speed data-over-cable systems, commonly referred to as the
DOCSIS 3.1 specifications. This specification was developed for the benefit of the cable industry, and includes
contributions by operators and vendors from North and South America, Europe, China and other regions.

This generation of the DOCSIS specifications builds upon the previous generations of DOCSIS specifications
(commonly referred to as the DOCSIS 3.0 and earlier specifications), leveraging the existing Media Access Control
(MAC) and Physical (PHY) layers, but with the addition of a new PHY layer designed to improve spectral
efficiency and provide better scaling for larger bandwidths (and appropriate updates to the MAC and management
layers to support the new PHY layer). It includes backward compatibility for the existing PHY layers in order to
enable a seamless migration to the new technology.

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).
