Claim:
1. A method of synchronizing communication in an electronic communication system with a central unit and multiple distribution points sharing a communication binder, the communication system further comprising a plurality of Customer Premises Equipment (CPE), transceivers, the method comprising: creating a common clock for the multiple distribution points; estimating respective time delays of respective communication paths from the central unit to respective distribution points and from distribution points to respective CPE transceivers; and using the estimated time delays to determine respective timing advances for the respective distribution points and respective CPE transceivers; causing the respective distribution points to align symbol timing of downlink transmissions from the distribution points to the CPE transceivers based at least on the respective timing advances, causing CPE transceivers to align symbol timing of uplink transmissions from the CPE transceivers to the distribution points based at least on the timing advances, thereby using the estimated time delays to avoid communication collisions in the system between the downlink transmissions and the uplink transmissions.
