Protocol for transceiver initialization
First Claim
1. A method for initializing a pair of transceivers of a multicarrier transmission system for subsequent transfer of data between the pair of transceivers over a link, said method comprising the operations of:
- (a) producing, at the first transceiver of the pair of transceivers, first direction performance information for data transmissions in a first direction;
(b) producing, at the second transceiver of the pair of transceivers, second direction performance information for data transmissions in a second direction;
(c) forwarding the second direction performance information from the second transceiver to the first transceiver;
(d) determining, at the first transceiver of the pair of transceivers, first direction bit allocations and second direction bit allocations, the first direction bit allocations being determined based on the first direction performance information and the second direction bit allocations being determined based on the second direction performance information; and
(e) thereafter forwarding the first direction bit allocations and the second direction bit allocations from the first transceiver to the second transceiver.

Abstract
Improved initialization techniques for initializing data transfer between a pair of transceivers in a multicarrier modulation transmission system are disclosed. The multicarrier modulation transmission system normally includes a central office and a remote unit, with the central office having at least one transceiver and the remote unit having a transceiver. For each pair of transceivers, the transceiver at either the central office or the remote unit controls the determining of bit allocations for both upstream and downstream data transmissions without assistance from the other transceiver of the pair. The initialization processing for the pair of transceivers is thus performed efficiently and with better centralized control.
