摘要： Relatively low cost asymmetric digital subscriber line (ADSL) service and auxiliary POTS service are delivered over extended distances (e.g., at least 20–25 kft), by a hybrid ADSL-SDSL architecture insertable between central office and remote sites of an ADSL system. Central office and remote site transceivers employ trellis coded pulse amplitude modulation and a data rate that conforms with the signal transport capability of an extended distance symmetric DSL (SDSL) loop, while providing a 64K POTS channel. The central office and remote site transceivers controllably insert idle asynchronous transfer mode (ATM) cells in upstream and downstream ADSL channels to compensate for timing differences with ADSL equipment.

摘要： An upstream transceiver, coupled to an upstream end of a long haul, single digital subscriber loop of an extended range asymmetrical digital subscriber line communication system, ‘spoofs’ a (co-located) digital subscriber line access multiplexer to reduce its downstream data rate over a short haul loop to the upstream transceiver. The reduced downstream data rate is compatible with the data rate that can be supported by the long haul loop and also accommodates an auxiliary (64K) POTS channel thereover. The reduced data rate may be derived by preliminary signal quality measurements upon the long communication loop conducted between the upstream transceiver and a downstream transceiver coupled to a remote end of the long haul loop.

摘要： State of the art data compression-protocol engines provide high compression ratios for improving data transport over a high data rate serial communication link. However, a respective data port of data terminal equipment may not be capable of being clocked at a sufficiently high clock rate, which limits the performance of the data compression-protocol engine, and prevents full utilization of the available bandwidth of the serial link. To remedy this problem, data terminal equipment and data compression-protocol engine components that provide auxiliary data communication port connectivity are employed. Data from the data terminal equipment is clocked to the data compression-protocol engine over a plurality of parallel data paths. This increases the effective clock rate and enables the data compression-protocol engine to output a compressed data stream that fully utilizes the bandwidth of the network. The data compression-protocol engine is programmable for either parallel data path transport or single path data transport to the network interface. In one embodiment, plural data streams from the data terminal equipment are compressed and then time division multiplexed onto the network. In a second embodiment, the data streams are statistically multiplexed into a single compressed data stream to the network.

摘要： Network bit efficiency for transmitting a limited size data frame over a digital communication system is enhanced by a macro-header encoding mechanism which replaces plural header portions of a data frame sequence with a single macro-header byte. The macro-header may be representative of protocol and signal processing operation fields that would otherwise require a longer overhead sequence as a precursor to data transmission. At the receiver, the macro-code is translated into a predefined sequence of opcodes, parameters and data bytes. Whenever the receiver requires another opcode, parameter or data byte, it initially looks to the macro-code. Otherwise, the necessary byte is obtained from the data frame segment being interpreted. Within a frame of data a multi-bit parameter header includes a first bit indicating whether the message is being aborted, a second bit indicating whether the frame is the first frame in the message, a third bit indicating whether the frame is the last frame in the message, a fourth bit indicating whether a sequence number follows, a fifth bit indicating whether the frame contains data representative of the length of the frame, a sixth bit indicating whether the frame contains data, a seventh bit indicating whether the frame contains frame check sequence signals, and an eighth bit indicating whether immediately following is an extension parameter header.

摘要： A fiber quadrupler device and method multiplexes the four optical fibers in a synchronous optical network (SONET) ring into a single linking fiber for full duplex optical transmission. The fiber quadrupler device optically couples two of the SONET fibers to a transmit converter for communications of downstream data from the SONET ring to a network element linked to the quadrupler by a single linking fiber. Two other SONET ring fibers are optically coupled to a receive converter for communications of upstream data from the network element over the single linking fiber to the SONET. An optical transceiver processes and directs the downstream and upstream signals to the receive and transmit converters. Either subcarrier modulation (SCM) or wavelength division multiplexing (WDM) is used in the receive and transmit converters.

摘要： The present disclosure generally pertains to systems and methods for allocating bonding engines among bonding groups. In one exemplary embodiment, a provision module is configured to allocate bonding engines. When selecting a bonding engine for a new bonding group, the provision module only considers bonding engines residing on access modules that terminate at least one of the communication links of the bonding group. Out of the bonding engines residing on access modules terminating at least one communication link of the bonding group, the provision module selects a bonding engine servicing the least number of external links and assigns the selected bonding engine to the bonding group. The provision module also provisions the access modules terminating the communication links of the bonding group such that the selected bonding engine bonds such communication links during operation.

摘要： In order to transport digital data across a reliable digital communication link from a transmit site to a destination site, the data is processed in parallel paths to derive error detection information, such as a cyclic redundancy code, and to encode the data. The outputs of the parallel paths are combined into a composite digital data sequence, which is then transmitted over the reliable digital communication link to the destination site. At the destination site, the encoded digital data component of the composite data sequence is decoded and then subjected to the same error detection operation carried out at the transmit site to derive error detection information associated with the decoded digital data. This recalculated error detection information is compared with the error detection information component contained in the composite digital data sequence. If there is a mismatch, the reliable digital communication link and the encoder at the transmit site and the decoder at the destination site are reset.

摘要： In order to ensure continuous telephone service to a customer premises served by an ISDN line, without requiring that the customer maintain an additional POTS line as an emergency back-up to the normally used ISDN service, ISDN signalling circuits and network termination interface components are modified, so that, in the event of a loss of power to customer premises digital communications equipment, a communication link between an auxiliary POTS telephone and the normal ISDN communication path to the central office may be established. There need not be any modification of the central office switch, per se, so that the integrity of the ISDN communication path with the central office line card remains unaffected. As a result, the central office equipment can continue to conduct standard ISDN communications with the customer premises equipment, even though the customer is employing a POTS back-up analog phone.
