摘要： A communications system 10 having an Asymmetric Digital Subscriber Line (ADSL) transceiver (24) is provided which may be configured either as a central office or a remote terminal in a system. The transceiver (24) operates in a listen/report idle state to report line activity to a host processor (22) prior to being configured as a central office or remote terminal. The host processor configures the transceiver (24) as a central office, remote terminal, or as otherwise specified based on the line activity.

摘要： A host processor (22) in a communication system (10) identifies a level of program visibility for reporting predetermined activation state changes, and signals a communications transceiver (24) to begin an initialization process. The communications transceiver (24) begins executing a series of states (51-55, 61-64) for initializing the communication system (10). A determination is made by the transceiver (24) whether a state change has occurred. A state change is identified and reported to a host processor (22) based on the program visibility select level.

摘要： A transceiver (5) for an asymmetric communication system such as asymmetric digital subscriber line (ADSL) includes a configuration register (71) defining operation at either a central office (CO) or a remote terminal (RT). The configuration register (71) includes a control bit (72) for selecting either CO or RT mode. The transceiver (5) includes a signal processing module (70) configured according to the state of the control bit (72). For example, a digital interface (70) converts transmit data into transmit symbols and converts received symbols into receive data. The digital interface (70) uses a large memory (158) as a buffer in the transmit path and a small memory (160) as a buffer in the receive path in CO mode. In RT mode, the digital interface (70) uses the small memory (160) in the transmit path and the large memory (158) in the receive path. The selective configuration allows a single integrated circuit to be used in both CO and RT equipment.

摘要： A communications system (30) includes a transceiver (42) for transmitting data from a plurality of bins. Specifically, the BER of the bins is substantially equalized by allocating data by determining a projected margin. The projected margin is calculated for each bin by subtracting a reference signal-to-noise value from an estimated bin signal-to-noise value. The reference signal-to-noise value is predetermined by theoretical calculation or empirical data and stored in a look-up table. Bits are allocated to the bin having the maximum projected margin. This provides the best BER without changing the transmit power.

摘要： A communications system (30) includes a transceiver (42) for transmitting a plurality of bins. Individual bin BERs (bit-error-rates) are iteratively equalized. This is accomplished by applying a fine gains adjustment to the transmit power of the transceiver (42). Specifically, the BER of the bins is equalized by calculating an adjustment gain and subtracting the adjustment gain from the bin currently having the maximum margin and adding the same adjustment gain to the bin currently having the minimum margin. The iterations continue until all of the bin margins are within a predetermined threshold. This changes the individual bin transmit power levels without substantially changing the aggregate transmit power level. The BER is substantially equalized, without causing the individual transmit power levels to exceed a predetermined range, such as that required by ANSI T1E1.4.
摘要翻译：通信系统（30）包括用于发送多个箱的收发器（42）。各个bin BER（比特误码率）迭代均衡。这通过对收发信机（42）的发射功率进行微调增益调节来实现。具体地，通过计算调整增益并从当前具有最大余量的分箱中减去调整增益并将相同的调整增益添加到当前具有最小余量的分组中来平衡分组的BER。迭代继续，直到所有的分页边距都在预定的阈值内。这样可以在不显着改变总发射功率电平的情况下改变单独的发射功率电平。 BER基本相等，而不会导致单个发射功率电平超过预定范围，例如ANSI T1E1.4所要求的范围。

摘要： In the present invention, carriers associated with a discrete multi-tone (DMT) communications system (10) are sorted according to bit allocation capacity. The number of bits needed to attain a specified bit rate are then allocated beginning with the carrier having the greatest bit allocation capacity and proceeding toward the carrier having the least bit allocation capacity until all bits to are allocated. Once allocated, the power to any unused bins is reduced. Different subsets of the carriers between line cards can be specified in order to reduce crosstalk between adjacent lines.

摘要： In the present invention, an ADSL system (10) identifies good bin as a bin capable of successfully transmitting data to a destination. A bad bin is identified as a carrier that is not capable of successfully transmitting data to the destination. A marginal bin is identified as a carrier that may be capable of transmitting data to the destination. The power to a bad bin is reduced and allocated to the marginal or good bin(s) to allow an increased bit rate. In another embodiment, the power to marginal bin is reduced and allocated to the good bin(s).

摘要： The present invention comprises a remote terminal (20) and a central office (30) as part of and ADSL system (10). Once a communication channel is open between the remote terminal (20) and the central office (30), the remote terminal (20) transmits channel specific information, application specific information, or both to the central office (30). Once the central office (30) receives the information, the central office (30) can select data rate options optimized for the downstream receiver (the remote terminal (20)). Based on the application specific and/or channel specific information, the central office (30) can use a combination of calculations and look-up tables to formulate new options. When the remote terminal (20) sends channel specific information, the central office (30) can perform calculations which determine performance margins at various data rates.
