摘要： A line unit interface circuit used on line units in a line shelf of a digital loop carrier provides all of the logic necessary to access two subscriber lines to a line unit interface bus connected to common equipment within the line shelf. Information received from the common equipment includes signaling data, configuration data and provisioning data, which is reconfigured and processed by the line unit interface circuit for controlling the subscriber line channels. Configuration data from the common equipment is decoded to assign time slots on the line unit interface bus to the various channels serviced by the line shelf and to further provide for a timing offset between the transmit and receive strobes provided to each subscriber line circuit. A flywheel circuit is used to prevent erroneous time slot assignment in the event of noise or interference on the line unit interface bus.

摘要： A three-ported apparatus is adapted to interface a serial TDM bus, a local controller and a line unit bus in a telecommunications terminal. All data passing between the TDM bus and the line unit bus is temporarily stored and is accessible to the local controller, allowing the controller to either pass said data without modification or provide modifications thereto. Signaling contained within the data may be translated to a form usable by the line unit through the use of translation tables down-loaded from inventory storage on the line units. For each line unit, the local controller programmably controls time slot assignment, provisioning and inventory information access.

摘要： In an optical fiber telecommunication transmission system, a remote terminal interfaces a high-rate optical fiber feeder line and a plurality of lower rate optical fiber distribution lines. The remote terminal includes a plurality of interfacing and signal cross-connecting devices which interface and cross-connect lower rate telephony signals with higher rate telephony signals. The plurality of interfacing and cross-connecting devices are interconnected with high-rate transmission lines so that telephony signals from under-utilized optical fiber distribution lines may be concentrated onto the high-rate optical fiber feeder line for efficient use of the feeder line.

摘要： In an integrated telecommunications network adapted to provide narrowband telephony signals and broadband switched video signals, control signals for the broadband video signals are transmitted in the narrowband as baseband signals, which are frequency division multiplexed with the broadband switched video signals. The video control signals are transmitted over the same transmission lines as the broadband video signals and do not require the installation of additional transmission lines. Control signals from a plurality of subscribers are multiplexed together at a network unit and are transmitted as a channel on an optical fiber, after which the channels from a plurality of network units are further multiplexed together to form a frame of control channels which are transmitted to a video controller unit.

摘要： A parallel time slot interchanger, particularly for use in telecommunication switching, comprises a plurality of switch groups, with each switch group containing a second plurality of channels. The parallel time slot interchanger incroporated a matrix-type architecture, with each module of the matrix comprising a switch block which in turn incorporates a switch memory, connect memory and associated control circuitry. The connect memory of each switch block is controlled by the control circuitry of that block. The data stored in the connect memory contains switch memory address information for reading channel data stored within the switch memory of the same switch block so as to be able to perform a time slot switching function during any given time slot of the parallel time slot interchanger. Each switch block is uniquely identified within its corresponding switch group so that only one switch memory address location is read and output during any time slot for each switch group.

摘要： An elastic storage circuit employs a first in/first out (FIFO) memory which stores data contained in a serial stream in a plurality of locations, each of which is associated with a unique address. The storage locations operate to store both the data and the address. A word address counter generates a five bit address code to accompany the data bits as stored in the FIFO. If a chronic increase or decrease in the frequency rate of the data occurs, the FIFO will overflow or underflow. This condition is detected by suitable detectors which create an alarm to completely reset the entire contents of the memory and to refill a portion of the memory over a given interval sufficient to permit the system to recover from the slip in the data rate and to thereafter synchronously read the data together with the address identification from the FIFO.
摘要翻译：弹性存储电路采用将多个位置中的串行流中包含的数据存储在第一输入/输出（FIFO）存储器中，每个位置与唯一地址相关联。存储位置操作以存储数据和地址。一个字地址计数器产生一个五位地址码，以便存储在FIFO中的数据位。如果发生数据频率的慢慢增加或减少，则FIFO会溢出或下溢。该条件由合适的检测器检测，该检测器产生报警以完全重置存储器的全部内容，并且在给定的间隔内重新填充存储器的一部分，足以允许系统以数据速率从滑移中恢复，然后同步从FIFO读取数据和地址标识。
