Abstract
A method (10) of encapsulating digital communications signals for transmission on a communications link, comprising steps: a. receiving a first signal of a first signal type and comprising a first clock signal and receiving a second signal of a second signal type, different to the first, and comprising a second clock signal different to the first clock signal, each clock signal having a respective clock value and accuracy (12); b. obtaining the first clock signal (14); c. obtaining a difference between at least one of the clock values of the clock signals and the accuracies of the clock signals (16) and buffering the second signal for a time at least long enough to compensate for the difference (18); and d. assembling the first signal and the buffered second signal into a frame comprising an overhead and a payload comprising a first portion and a second portion, mapping the first signal into the first portion and the second signal into the second portion (20), wherein step d. is performed using the first clock signal.
