摘要： A method for identifying faulty modules within telecommunication devices, such as ATM switches, involves generating and attaching verification codes, such as a CRC or checksum codes, to data packets at an upstream location determining the integrity of the verification codes at each of multiple downstream location within a telecommunication device; and signaling an error condition where a corrupted data packet has been detected. A verification code may be written to a field of a data packet which is not used while the packet is in transit through the telecommunication device.

摘要： A method for identifying faulty modules within telecommunication devices, such as ATM switches, involves generating and attaching verification codes, such as CRC or checksum codes, to data packets, such as ATM cells, at an upstream location, determining the integrity of the verification codes at each of multiple downstream location within a telecommunication device; and signaling an error condition where a corrupted data packet has been detected. A verification code may be written to a filed of a data packet which is not used while the ATM cell is in transit through the telecommunication device, thereby identifying a faulty module device without adversely affecting throughput.

摘要： A method for verifying the integrity of data payloads of ATM cells passing through a switching device involves computing a payload integrity verification code for the payload portion of an ATM cell. The payload integrity verification code may be generated according to any error detection or error correction scheme. Preferably, the payload integrity verification code is stored in a portion of the standard ATM cell header which is not used while the cell is passing through the switching device. Preferably the payload integrity verification code is stored in all, or a portion of, the virtual path identifier or virtual connection identifier fields. The invention allows for the immediate identification of cells having corrupted payload data. Different actions may be taken on the detection of errors in the ATM cell header and ATM cell payloads respectively.

摘要： A system and method for increasing the data rate of a system bus without making modifications to existing (legacy) devices connected to the bus. A logical bus is overlaid onto one or more physical buses in a TDM manner. The overlaying is done by transmitting data into the one or more existing buses during a previously unused phase of the bus clock having no effect on existing devices connected to the buses. The additional devices are capable of latching data on either phase bus clock.

摘要： Methods and devices for detecting cell loss in telecommunication devices, such as ATM switches, attach cell loss detection information to cells in cell streams passing through the telecommunications devices. The cell loss detection information can trigger counters at up stream and down stream locations thereby avoiding the problem of synchronizing counters and ensuring that all cells to be counted have been flushed through the telecommunications device. The cell loss detection information can include a sequence number in a sequence of n sequence numbers where n is not a power of 2. Preferably n=2P−1, where P is an integer. Such series of sequence numbers allow the detection of lost cells in bursts consisting of a number of lost cells which is a power of 2. The methods and apparatus of the invention permit detection of unintentionally dropped cells in a call without the need to tear down the call.
摘要翻译：用于检测诸如ATM交换机的电信设备中的小区丢失的方法和设备将小区丢失检测信息附加到通过电信设备的小区流中的小区。信元丢失检测信息可以在上行流和下行位置触发计数器，从而避免同步计数器的问题，并确保要计数的所有单元已经通过电信设备刷新。细胞损失检测信息可以包括n个序列号的序列中的序列号，其中n不是2的幂。优选n = 2-P，其中P是整数。这样的一系列序列号允许在由多个丢失的小区组成的突发中检测到丢失的小区，该小区的功率为2.本发明的方法和装置允许在呼叫中检测到无意丢弃的小区，而不需要拆除呼叫。
