    Abstract: In fiber telecommunications network where an optical fiber is extended to the subscriber's neighborhood, mechanized loop testing is performed by a test unit located in a network unit in the subscriber's neighborhood. The test unit is responsive to commands from a controller located in the network unit to perform metallic line tests on the lines extending to the subscriber. Test results are stored in a memory associated with the controller in the network unit. Upon receipt of a test request from a central test controller, the controller within the network unit determines if there is sufficient time to perform the test; if so, a new test is performed and the results are conveyed back to the central test controller controller. If sufficient time is not available, the results of the last performed routine test contained in the memory are transmitted back to the central test controller. The test results sent back to the central test controller are conveyed firstly in the form of a particular four-digit code, which code is interpreted at a remote terminal and converted to a specific resistive signature which is conveyed back to the central test controller. The specific resistive signature is interpreted by the standard remote measurement unit located in a remote terminal.

    Abstract: 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.

    Abstract: 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.

    Abstract: A digital debouncing and storage apparatus operates on the receiving end of a digital carrier span line used in a telephony system to couple a multiplex signal to a receiving site to be used by the switching network control. Incoming signaling bits of the multiplex signal are stored in a random access memory at a particular storage location reserved for each channel contained in a group. There is also stored at the location previous timing information concerning each sampling bit. The circuit operates to time any change in the value of a status bit to insure that it lasts long enough to indicate a valid change of state. An up/down counter serves to time each status bit during predetermined signaling frames based on a count inserted into the counter indicative of the timing information as stored in memory. Thus each channel associated with the multiplex signal has stored in memory a unique status bit as well as timing information pertinent to that bit. The circuit operates over a predetermined number of frames whereby if the status of the bit has changed between one binary value to another, the circuit will recognize such a change only after a given number of signaling frames have elapsed. In this manner, contact bounce or channel interference which may effect the signaling bit is eliminated from interferring with system operation.
