Abstract: A system and method for monitoring the status of a system of battery strings is described. The system includes a current sensor for each of the battery strings, and a controller configured to compute the average current from the measured currents. The state of the battery system is determined as being fully charged, discharging or charging, and the individual battery string currents are compared with the average measured current to determine if the currents are within a threshold value. An alarm indication is provided when one or more of the currents exceeds a threshold difference. The system may provide a local indication of status and may also interface with a communications network to provide for remote monitoring.

Abstract: A system and method for monitoring the status of a system of battery strings is described. The system includes a current sensor for each of the battery strings, and a controller configured to compare the measured current with criteria to determine whether the battery is in a thermal runaway state. Prior to entering the thermal runaway state the battery current characteristics may indicate other less serious states. Warning messages are provided for selected events, and the battery string is disconnected from the remainder of the system when a thermal runaway state is encountered. The system may provide a local indication of status and may also interface with a communications network to provide for remote monitoring.

Abstract: A DC power supply system in which the resistance of a battery is measured. The voltage of the DC power supply is reduced such that the battery supplies some current to the load, and the voltage and current are measured. The voltage of the DC power supply is further reduced such that the battery supplies increased power to the load, and the voltage and current are measured. A resistance value is computed, and may be compared with various pre-established criteria. The battery resistance may also be measured by comparing the charging time of a known resistive-capacitive circuit with the charging time established at a prior measurement epoch.

A second pre-determined number of channels on each of the transmit and receive lines is provided for on the multi-function bus. A multi-function bus includes the transfer of information to and from the host switching system both in a serial mode and in a parallel mode on the multi-function bus.

Abstract: An improvement is disclosed for telecommunication PCM time division multiplex switching systems of the type having voice access ports, each with a voice path and a signalling path, and having PCM signalling and voice transmit buses to carry information to a switching network. From the network, PCM voice receive buses carry switched voice information to be demultiplexed, converted to analog form and connected to the voice port. A signalling bus carries information from the switching network to registers. The system is improved to enable it to switch data as well as voice information. A data port is provided to accompany each voice port, and the improved system includes means for multiplexing input data at the port and inserting it on the signalling transmit bus once the signalling portion of a call is completed. A receive data bus connects the signalling receive bus to means for demultiplexing data and presenting it to receive data ports.

Abstract: Automated telephones with electronic circuits for outputting dial digit sequences respectively corresponding to different ones of a plurality of user's switches when each switch is momentarily actuated. The circuits permit speed dialing of (i) directory numbers, (ii) tandem sequences for accessing outside centers and specific line numbers, and (iii) access or feature codes. The apparatus is characterized especially by devices to create automatically loop breaks to simulate either a hook flash or a re-seize on-hook condition in certain circumstances and despite the fact that the telephone remains off-hook. By simple wire connections between a master or "secretary's" telephone and each of the member's phone sets within a limited group, intelligence signals are interchanged to provide "key line group" action without an elaborate, separate "control box" and even though each telephone of the group is served by the central system only via its own two-wire line.

Abstract: A microprocessor control complex for a telecommunications switching system disclosed in the context of a digital time division multiplex switching system. The control complex is arranged as a cluster of hardware identical microprocessors in a distributed processing configuration wherein each microprocessor is provided with its own memory and clock and is programmed to perform a portion of the total function of the switching system. Each microprocessor performs the functions assigned to it independently and asynchronously of the others. Data is transferred between microprocessors in a manner which minimizes the amount of time spent in interprocessor communication. This communication is accomplished via interprocessor buffers which provide dedicated communication channels between partner processors while allowing those processors to continue to operate asynchronously. The distributed control complex allows the software to be modularized with resulting economies in program generation and debugging.

Abstract: A method and means for providing a remote data station with access to the program memory of a stored program common control telecommunications switching system. The control complex has an input/output port and a modem for interfacing that port with its switching network. The control has the capability of setting up connections in the network between the modem and a selected trunk. Incoming connections to the modem are given only limited access to the stored program control, that access for the purpose of analyzing incoming data to detect a predetermined code. In the event the predetermined code is detected, the incoming connection is taken down, and an outgoing connection established to a distant station by dialing the number of an authorized station which is stored in the program memory. Full access to the program memory is then allowed, such that full access is provided only to stations whose telephone numbers are stored in the memory of the switching exchange.
