摘要： A telecommunications switching apparatus (10) includes optical paths (16-19) coupled to interface cards (26-29), which in turn are coupled to a switching circuit (41-42). The switching circuit is coupled to a plurality of universal connectors (71-74), each of which is coupled to an auxiliary connector (77-78). The universal connectors can each removably receive any one of several types of switching circuit cards (101-104), which each utilize a respective one of several different communication protocols. An auxiliary circuit card (107-108) may be provided in the associated auxiliary connector, in order to support switching circuit cards that use certain communication protocols. The optically transmitted information includes segments formatted according to respective communication protocols, and is converted from optical to electrical form by the interface cards. The switching circuit then routes each segment to a respective universal connector containing a switching circuit card that effects switching according to the communication protocol of that segment.

摘要： An asynchronous serial crosspoint switch is word synchronized to each of a number of transceiver circuits. The crosspoint switch circuit generates both a master bit clock and a master word clock signal. A transceiver circuit recovers the master bit clock signal from an incoming high-speed serial data stream using a clock and data recovery circuit. The recovered bit clock signal is used as a timing signal by which data is serialized and transmitted to the crosspoint switch circuit. The data stream transmitted to the switch circuit is frequency locked to the master bit clock signal, such that the serial data stream need only be phase adjusted with a data recovery circuit. To recover word timing, the switch circuit issues alignment words to the transceivers during link initialization. The transceivers perform word alignment and establish a local word lock. Alignment words are then reissued to the switch circuit using the local word clock. The switch circuit compares the boundary of the received word clock to the master word clock and, if misaligned, the transceiver shifts its transmitted word by one bit and retries. Necessary edge transition density is provided by overhead bits which also designate special command words asserted between a transceiver and a switch circuit. Flow control information is routed from a receiving transceiver back to the transmitting transceiver using the overhead bits in order to assert a ready-to-receive or a not-ready-to-receive flow control signal. The overhead bits additionally provide information regarding connection requests and other information.

摘要： Universal Serial Bus active extension cable for increasing the distance between devices coupled via a Universal Serial Bus cable includes a pair of transceivers for bidirectional transmission of data therealong. A drive detector senses which terminal device is transmitting data and enables the other terminal device to receive the data. A speed detector senses which of more than one transmission speed is being used and sets the devices coupled to the cable accordingly. An end-of-packet detection determines when the transmission of a packet of data has been completed. When the system enters a suspend mode, a detector sets the components to a low power mode.
