Broadband Cable Access

 

Broadband Cable Access

Coaxial cable nets have been widely deployed to distribute tv offerings using the broadcasting era. This infrastructure has been more desirable and advanced into a Hybrid Fibre Coax (HFC) architecture in conjunction with the introduction of a return channel. The enterprise is now deploying virtual tv services, high-pace statistics services, Internet Protocol (IP) voice, and different time-critical multimedia services across these broadband cable telecommunication community technologies.

These offerings are introduced using the DOCSIS and IPCablecom protocols. DOCSIS® is a data verbal exchange protocol for the obvious transmission of IP traffic throughout the HFC infrastructure. IPCablecom has been industrialized to deliver telephony and other Quality of Service (QoS) more advantageous, comfortable IP multimedia, time important communications offerings, the use of packetized records transmission technology on an HFC data community utilizing the DOCSIS protocol.

ETSI’s Technical Committee CABLE is answerable for the introduction, development, and maintenance of requirements associated with incorporated broadband cable telecommunication community technology consisting of:

informationntechnology

community terminals e.G. Cable CPE devices and network terminating devices

network infrastructure, inclusive of network topologies, HFC community distribution, records over cable systems, and frequency management

offerings added throughout included broadband cable telecommunication networks

electricity efficiency and sustainability for included broadband cable telecommunication networks

safety of integrated broadband cable telecommunication networks and offerings

OUR ROLE & ACTIVITIES

Cable manufacturing is a global market, and consequently, ETSI’s cable standards are developed to align to the volume viable with standards both already evolved or under development in other areas. TC CABLE is answerable for the introduction, development, and upkeep of requirements and other ETSI deliverables related to incorporated broadband cable telecommunication community technologies.

The ETSI specs are constant to the extent feasible with the CableLabs®/PacketCable™ set of specs as posted via the Society of Cable Communications Engineers (SCTE). In many of its doings, TC CABLE leverages near relationships with SCTE, CENELEC, and ITU-T.

In latest years, ETSI has performed important milestones with the ebook of a suite of requirements describing DOCSIS 3.Zero (EN 302 878 collection) and IPCablecom 1.Five (TS 103 161). DOCSIS three.0 provides for superior features, which include the capability to bond a couple of channels collectively and support IP model 6, at the same time preserving backward compatibility with the primary generation (ES 201 488) and 2d generation (ES 202 488).

In 2019, TC CABLE completed any other milestone on standards for broadband cable network generation with the e-book of a multi-part specification [ES 203 311 series] for the fourth-era transmission structures for interactive cable tv services (IP cable modem). The state-of-the-art version three.1 of the Data Over Cable Service Interface Specification (DOCSIS) – one of the central technology for cable get admission to networks – became an ETSI Standard (ES). The collection of requirements spans the DOCSIS three. One physical layer [ES 203 311-2]; MAC and top layer protocols [ES 203 311-3]; cable modem operations aid system interface [ES 203 311-4]; converged cable get right of entry to platform operations assist device interface [ES 203 311-5]; and protection [ES 203 311-6] aspects.

In the past years, ETSI's TC CABLE additionally labored on standards for the transition of the broadband cable telecommunication infrastructure to IPv6 and on the electromagnetic environment. An awareness of TC CABLE outside verbal exchange has been the contribution to the ETSI function inside the Experts Group on Reconfigurable Radio Systems and Radio Equipment of the European Commission.

Ongoing recognition of TC CABLE is paintings on strength management for cable networks, in reaction to European Commission (EC) Mandate 462 (M/462) on electricity efficiency in facts and communication networks.
