摘要： In a frame buffer monitoring method and device, information concerning a received frame is extracted, and a monitoring frame added to a start of the frame is written in a FIFO buffer. When the monitoring frame is read from the FIFO buffer, expectation information is generated from the information concerning the frame added to the start of the monitoring frame read, the expectation information is compared with the information concerning the frame included in the frame within the monitoring frame read, and whether or not the expectation information is consistent with the information concerning the frame is determined. As a result of the comparison, when it is determined that the expectation information is not consistent with the information concerning the frame, e.g. bits of an FCS within the frame which is determined to be inconsistent are inverted to be transmitted to a subsequent stage as a discarded frame or the frame is discarded. Also, a write destination address and a read source address for the FIFO buffer are initialized.

摘要： A time-slot interchanger includes first and second time switches and a space switch installed between the first and second time switches. The first time switch includes a first part for supplying data, which is produced by adding a blank region to input data supplied to the first time switch, in n systems (n is an integer), in parallel to the space switch. And the second time switch includes a second part for supplying output data, which is produced by removing the blank region from data received in the n systems and in parallel from the space switch.

摘要： A pulse insertion circuit alternately distributes serial input data at a predetermined data clocking rate into first and second parallel input data, which are synchronously and simultaneously written into and read from a memory, the second input data as read being delayed by one bit. A selection means selects between the second input data and the one-bit delayed second input data and further switches between and establishes either a direct or a cross connection between the selected one of the second input data, as read or as delayed, and the first input data and the first and second output terminals thereof, at which there are produced, correspondingly, parallel and selected, first and second input data. A control means responds to a pulse insertion request to inhibit memory read-out by one read clock period and to control the switching means selectively to switch between the direct and cross-connections, the pulse addition being made to one of the parallel and selected, first and second input data, as specified by the pulse insertion request. Pulse insertion thus is performed at one-half the predetermined clocking rate, the selected and parallel, first and second input data with the required pulse inserted in the specified one thereof, thereafter being multiplexed and transmitted at the predetermined clocking rate.
