English

Subject field(s)
  • Wireless and Mobile Communications
  • Radiotelephony
  • Radio Transmission and Reception
DEF

A regularly interacting group of base, mobile and associated control and fixed relay stations intended to provide land mobile radiocommunications service over a single area of operation.

CONT

A land mobile radio (LMR) system is a public or private two-way wireless communication network commonly used by public safety organizations such as police, firefighters and emergency responders for critical communications. These systems are also used for industrial, transportation, utilities, security, logistics and military applications. A typical LMR system consists of handheld portable radios, vehicle mounted mobile radios, base stations and repeaters, and other supporting network infrastructure.

Record 7 2009-02-11

English

Subject field(s)
  • Electrical Appliances and Equipment
CONT

This system limits the closing device to effect a single attempt while the signal to close is maintained. If the device fails to complete a satisfactory close operation whilst the close signal is maintained, then attempts at further reclosing(pumping) are inhibited. An anti-pumping can be achieved in the closing control circuit in various ways, either by using circuit-breaker mechanism auxiliary switches or a timing relay. It only allows a single closing pulse to the closing device, which resets when the initial closing signal is released.

Record 8 2004-07-14

English

Subject field(s)
  • Telephone Switching
OBS

A selective, multi-unit, two-stage relay, configured with 10 or 20 horizontal paths. A two-stage operation is used to close any cross-point. First, a selecting magnet shifts all springs in a horizontal row, then a holding magnet shifts a vertical actuating card to close the selected contacts.(SMICO, 71 : 392) The crossbar switch, which is used for all major switching operations, forms the basis of the crossbar dial system. It is made up of the three main parts : 10 or 20 vertical circuit paths, 10 horizontal circuit paths, and equipment to close(connect) a circuit from any one to the other.(LEETEL 1, 76 : 79)
