This standard will encompass two levels of interface, defining operation overdistances less than 10 m. The physical layer will specify electrical, mechanical, and thermalcharacteristics of connectors and cards. The logical level will describe the address space,data transfer protocols, cache coherence mechanisms, synchronization primitives, control andstatus registers, and initialization and error recovery facilities.
This Annex defines the architectures and functional aspects of the SDH-DRRS aiming at their complete operationalintegration in a SDH-based network.
The aim of this Report is to show how the FS could be used at different hierarchical levels of the transport network of IMT-2000, in order to ensure the connections between base stations, and between base stations and higher-level stations within this transport network. This Report provides an example of the use of the FS in the transport network of IMT-2000.
ITU-T Recs H.610 and H.611 define the architecture and operations, administration monitoring and provisioning (OAMP) requirements for the delivery of video, data and voice services across a VDSL access network to an in-home environment, known as a Full-Se
The purpose of this Technical Report is to be a first guideline for those considering to install a high bandwidth (high bit-rate) FTTx-network. After studying the Technical Report operators, communities, energy companies, installers and others will understand the necessary steps to take to plan and install FTTx-networks with high quality and cost effectiveness, and to secure a uniform structure and a high quality level on such networks.
The document provides instructions on the methods to be used when installing, repairing or modifying aircraft electrical and optical fibre interconnection systems, subject to the limitations defined in 4 of this document.
This part of IEC 61375 applies to data communication in Open Trains, i.e. it covers data communication between consists of the said open trains and data communication within the consists of the said open trains.
