  • Patent number: 4477895
    Abstract: A multichannel data link switching control arrangement for synchronizing the substitution of one data channel for another without causing the insertion or deletion of data bits from the data transmitted over the communication path that is coupled to the channels. The switching control arrangement monitors the relative timing between the data on a channel to be replaced and the data on the replacement channel. Precisely controlled delay circuitry delays the data on one channel relative to the other until the data signals on the two channels are within .+-. a quarter bit of each other, at which time the channel substitution is effected.The arrangement includes a pair of control switch units each of which may be selectively controlled to couple either the active channel or the replacement channel to an output communication link. Each switch control unit contains an input multiplexer and an output switch, the operations of which are controlled by a data timing monitoring apparatus or control unit.

  • Patent number: 4451916
    Abstract: A repeatered, multichannel fiber optic communication network includes a plurality of full duplex fiber optic channels and one or more auxiliary channels. In order to supervise and control the operation of the network, for both data transmission and fault/maintenance actions, each terminal station contains a processor-based subsystem capable of network monitoring, first level maintenance action, fault isolation, and remote network control and status reporting. This processor-based subsystem interfaces with each fiber optic channel, with an orderwire communication link, and with external input/output devices and surveillance equipment. Three substantially autonomous processor-based sections which are dedicated to performing specific functions within the overall network operation are employed for carrying out these separate interfacing tasks.
