Additional clock filtering is supposed to be done at lower data rates. Jitter transfer bandwidth will be defined at this level which is a parameter of the whole network element and not of the receiver element. A further version is under investigation to met simultaneously all the GR-253/ITU-T G958 jitter specifications at the physical interface level.
