SYSTEMS AND METHODS FOR AVOIDING CROSSTALK
First Claim
1. A distribution point, comprising:
- a first distribution point (DP) transceiver coupled to a first point-to-point (PTP) connection and configured to communicate with a first customer premises (CP) transceiver via the first PTP connection;
a second DP transceiver coupled to a second PTP connection and configured to communicate with a second CP transceiver via the second PTP connection; and
a controller configured to dynamically schedule transmissions across the first and second PTP connections such that the controller ensures, for at least a period of time, that transmissions across the first PTP connection are prevented from overlapping in time with transmissions across the second PTP connection thereby avoiding crosstalk between the first and second PTP connections during the period of time.

Abstract
A controller at a distribution point (DP) of a communication system is coupled to a plurality of customer premises (CP) transceivers via drop connections. The controller is configured to schedule upstream and downstream data transmissions across the drop connections such that they do not overlap from one drop connection to another thereby avoiding the effects of crosstalk. A flexible frame structure is used to permit dynamic scheduling changes. Overhead for the flexible frame structure is permitted to overlap on the drop connections, and a reduced bit loading is used to communicate the overhead relative to the bit loading used for data transmissions.

7. A method for use at a distribution point, comprising:
-
communicating between a first distribution point (DP) transceiver and a first customer premises (CP) transceiver via a first point-to-point (PTP) connection having an end coupled to the first DP transceiver and an end coupled to the first CP transceiver; communicating between a second DP transceiver and a second CP transceiver via a second PTP connection having an end coupled to the second DP transceiver and an end coupled to the second CP transceiver; and scheduling transmissions across the first and second PTP connections, wherein the scheduling comprises ensuring, for at least a period of time, that transmissions across the first PTP connection are prevented from overlapping in time with transmissions across the second PTP connection thereby avoiding crosstalk between the first and second PTP connections during the period of time. - View Dependent Claims (8, 9, 10, 11)
