1. A communication system, comprising:

  • a first distribution point positioned along a trunk extending from a network facility, the first distribution point having a first service unit coupled to a first plurality of communication connections of the trunk and configured to receive from the first plurality of communication connections a plurality of data flows destined for customer premises (CP) transceivers at a plurality of customer premises, each of the first plurality of communication connections shared by each of at least a first plurality of the CP transceivers; and

    a second distribution point positioned along the trunk and having a second service unit coupled to the first service unit via a second plurality of communication connections of the trunk, each of the second plurality of communication connections shared by each of at least a second plurality of the CP transceivers,wherein the first service unit is configured to employ crosstalk vectoring to cancel crosstalk affecting signals communicated across the first plurality of communication connections, wherein the first service unit is configured to employ crosstalk vectoring to cancel crosstalk affecting signals communicated across the second plurality of communication connections, wherein the first service unit has a control element configured to receive control information from the second service unit, wherein the control element is configured to determine, based on the control information, an amount of excess capacity that exceeds a guaranteed aggregate service rate for communicating across the second plurality of connections, and wherein the control element is configured to control error correction for signals communicated across the second plurality of communication connections based on the determined amount of excess capacity.
