摘要:
An apparatus for synchronizing a plurality of digital subscriber line access multiplexers (DSLAMs) comprising a reference clock configured to generate a reference clock signal, and an interface configured to transmit the reference clock signal to the DSLAMs, wherein each of the DSLAMs is configured to align its system clock with the reference clock.

A processing method and a transceiver for channel changing in a joint transceiving mode are provided. The method includes: performing fault detection for one or more direct channels; after a fault is detected on a direct channel, stopping sending signals on the direct channel; detecting whether the direct channel with fault has been recovered; and when recovery of the direct channel with fault is detected, resuming sending signals on the direct channel.

摘要:
A method for returning a signal error in a multi-carrier communication system is disclosed. A specific sub-carrier interval is determined. The specific sub-carrier interval is larger than an interval between adjacent sub-carriers in the multi-carrier communication system. A signal error is returned to a central office end on a corresponding frequency in a communication frequency band of the multi-carrier communication system at the specific sub-carrier intervals.
