PURPOSE AND SCOPE This guide provides a single, comprehensive reference of current practice in the geometric design of transit facilities on streets and highways. The facilities covered include: • Local buses, express buses, and bus rapid transit operating in mixed traffic, bus lanes, and...
ulharm-1691.1 Single Pole Locking-Type Separable Connectors UL 1691 1 Scope 1.1 These requirements cover single pole locking-type separable attachment plugs, cord connectors, panel inlets, and panel outlets, adapters, and accessories, rated up to a maximum of 800 amperes and up to 600 volts ac or...
The present document specifies technical characteristics and methods of measurements for digital terrestrial television broadcast receivers fitted with an external antenna input (tuner port) capable of receiving DVB-T and/or DVB-T2 signals. Receivers without external antenna connectors,...
This Recommendation describes the functional requirements for radio over Internet protocol (RoIP) transmission systems based on data over cable service interface specifications (DOCSIS). The purpose of an RoIP system is to transmit data (DOCSIS based) over an upstream (US) radio frequency...
This document provides user guidance for the selection and proper application of protectors for relatively shorter coaxial cable runs outdoors for purposes of transmitting DS-3 or GPS PRS L1 timing signals. Background & Purpose Historically, traditional (non-CATV) telecommunications..
This standard defines an Emergency Alert signaling method for use by cable TV systems to signal emergencies to digital receiving devices that are offered for retail sale. Such devices include digital settop boxes that are sold to consumers at retail, digital TV...
This standard defines two raster-scanning systems for the representation of stationary or moving twodimensional images sampled temporally at a constant frame rate. The first image format specified is 1280 x 720 samples (pixels) inside a total raster of 750 lines, as given in Table 1. The second...
This Standard applies to uninterruptible power supplies (UPS). The primary function of the UPS covered by this Standard is to ensure continuity of an alternating power source. The uninterruptible power supplies can also serve to improve the quality of the power source by keeping it within specified...
This Standard covers mechanical and electrical requirements for aircore broadband twisted pair telecommunications cable with polyolefin insulated copper conductors. Broadband cables as described in this Standard are primarily intended to supply broadband services from the remote...
This Standard covers mechanical and electrical requirements for filled broadband twisted pair telecommunications cable with polyolefin insulated copper conductors. Broadband cables as described in this Standard are primarily intended to supply broadband services from the remote switch...
CEA-770.2-D defines the physical characteristics of an interface and the parameters of the signals carried across that interface, using three parallel channels for the interconnection of equipment operating with analog component video signals. CEA-770.2-D includes specifications for:...
This Recommendation describes objectives, requirements and functional architecture for a residential gateway (RG) supporting broadcast and IP-based interactive services over cable television networks. The RG is supposed to be used with a hybrid set-top box (H-STB) composed of RF TV...
