摘要： Following a transmission comprising a plurality of symbols, an error measurement is generated for each symbol, so that one may distinguish between symbols having a relatively low error and symbols having a relatively high error. A bit rate to be used for subsequent transmission is determined as a function of error measurements of those symbols that have relatively low error and as a function also of the proportion of symbols having a relatively high error, such that the bit rate reduces as the proportion increases. Measurement of the error rate and/or the durations of high and low error conditions may also be used to set other transmission parameters such as error-correcting code and interleaver settings.

摘要： An electrically powered node (3) of a telecommunications system has a battery power backup (37) associated with its power control unit (33). Under normal conditions it are maintained fully charged by means of trickle currents from the mains power feeds (14) to each of a number of mains- connected customer equipments (4), by way of the "final drop" (10) to the distribution point. These trickle currents are controlled by the respective power control units (33, 43), to prevent overcharging. Using an electrical copper connection (19) provided in parallel with the fibre connection (9), a battery backup (27) can also be maintained in nodes (2) further towards the exchange. These feeds are made reversible, so that if a power outage removes the power supply (14) from the customer premises (4), a "lifeline" plain telephone service between the exchange (1) and the telephone handset (5) is maintained over the connections (9, 10, 13), using the local battery backup (27, 37) in the remote nodes (2, 3). By limiting the service to simple telephony, the battery power (27, 37, 47) can be sufficient to maintain the service for a reasonable duration. The power management systems (23, 33, 43) can be used to transfer charge from one battery (27, 37) to another over the network according to the usage, or remaining life, of each battery (27, 37, 47).

摘要： The present invention relates to a method of communication between a central station that transmits downstream data units in a downstream direction and a remote station that transmits upstream data units in an upstream direction such that the upstream and downstream data units are transmitted in synchronism with one another, including the steps of: (i) receiving at the central station an acknowledgement message residing in an upstream data unit, which acknowledgement message relates to a downstream data unit previously transmitted from the central station; and, (ii) on the basis of the temporal position of the upstream data unit in which the acknowledgement message resides, making an inference as to which of the transmitted downstream data units the acknowledgement message relates. Because the identity of the downstream frame is inferred on the basis of the temporal position of the upstream data unit in which the acknowledgement message resides, the need for the acknowledgement message to itself contain an indication of the identity of said downstream frame is reduced. As a result, the acknowledgement message consumes only a small bandwidth.
摘要翻译：本发明涉及一种在下行方向发送下游数据单元的中心站与在上游方向上发送上行数据单元的远端站之间进行通信的方法，以使上下游数据单元彼此同步发送包括以下步骤：（i）在中心站接收驻留在上游数据单元中的确认消息，该确认消息与先前从中心站发送的下游数据单元有关; 和（ii）基于确认消息所在的上游数据单元的时间位置，对确认消息所关联的发送的下游数据单元中的哪一个进行推断。由于根据确认消息所在的上游数据单元的时间位置来推断下行帧的身份，所以对包含所述下行帧的身份的指示的自身确认消息的需求减少。结果，确认消息仅消耗小的带宽。

摘要： In an FTTDP optical fibre network, Distribution point units are reverse powered by customer premises equipment and therefore liable to power failure. When the distribution point unit loses power it is unavailable to respond to requests for performance or metric data. A persistent manager agent functions as a proxy for the distribution point unit, gathering metric and performance data from the distribution point unit using at least one EOC channel and handling requests for performance and metric data issued from other network devices. The persistent manager can also schedule downloads of firmware and configuration data to the distribution point unit.
