Abstract

See full text

Methods, systems, and apparatus for preserving timing domains of different communications types of signals in a telecommunications network are disclosed. In one aspect a network element (NE) includes a receiver configured to receive communications signals of two different communications types. The NE can include a timing analyzer configured to obtain a local reference clock (LRC), detect two different received reference clocks (RRCs) corresponding to the two different communications types, and for each received communications signal, determine a quantized value (QV) based on a difference between the LRC and the RRC. The NE can include a timing generator configured to generate, for the received communications signal, a transmit reference clock (TRC) that is referenced to, but different from, each of the LRC and the QV. The NE can include a transmitter configured to output an output signal based on the received communications signal and the TRC for the received communications signal.
