Refers to signals which are arbitrarily close in frequency to some defined precision. They are not sourced from the same clock and so, over the long term, will be skewed from each other.

OBS

Their relative closeness of frequency allows a switch to cross connect, switch, or in some way process them. That same inaccuracy of timing will force a switch, over time, to repeat or delete frames (called frame slips) in order to handle buffer underflow or overflow.

OBS

plesio: close, near, like.
