The concurrent communication system further includes transceiver circuitry with at least one transmission chain and at least four reception chains. The architecture of this system offers an efficient and inexpensive way to communicate on at least two TDD bands concurrently with reduced hardware cost.

In response to determining that the new CE value is not equal to the default CE value, the system can update and apply a CE value for the G.Fast cable in the G.Fast circuit to the new CE value. If, however, the new CE value is equal to the default CE value, the system can instead apply the default CE value.
