Abstract
A band control system for a digital subscriber line network in which a first apparatus and a second apparatus situated at a subscriber station and a center, respectively, are interconnected by a cable for interchanging at least a digital data signal with each other. The system may cause one of the first apparatus or the second apparatus to monitor receipt of signals from the other of the first apparatus or the second apparatus; send, based on a result of monitoring, a band variation command to the other apparatus for causing the other apparatus to vary a band by using a frequency band not used for signal transfer; cause the other apparatus to receive the band variation command; and vary the band in accordance with the band variation command.
Claims20
A method comprising:
- determining, by a device, that a quantity of cells, associated with data received via a frequency band, exceeds a first threshold or that a ratio of discarded cells, associated with the received data, exceeds a second threshold;
- and
- instructing, by the device, another device to adjust the frequency band in response to determining that the quantity of cells exceeds the threshold or that the ratio of discarded cells exceeds the second threshold, the adjusted frequency band being different than the frequency band.
A network device comprising:
- one or more components to:
- monitor a quantity of cells or a ratio of discarded cells,
- where cells, included in the monitored quantity of cells, and cells, included in the ratio of discarded cells, are associated with data that is received via a frequency band;
- and
- instruct, based on monitoring the quantity of cells or the ratio of discarded cells, another device to adjust the frequency band when the monitored quantity of cells exceeds the first threshold or when the monitored ratio of discarded cells exceeds the second threshold, the adjusted frequency band being different than the frequency band.
A system comprising:
- a device to:
- determine that a quantity, associated with data received via a frequency band, exceeds a first threshold or a ratio, associated with the received data, exceeds a second threshold;
- instruct the other device to adjust the frequency band when the quantity exceeds the first threshold or when the ratio exceeds the second threshold, the adjusted frequency band being different than the frequency band;
- and
- receive, in response to instructing the other device, other data from the other device via the adjusted frequency band.
