Re: What is 802.3ae WAN-PHY?




David,

The OTN will also require a certain clock accuracy. This is
one of the topics currently under discussion in ITU-T. ITU-T
needs to be made aware that is needs to support 200 ppm client
signals.
They will not like it; it requires more bandwidth.

Regards,
    Erik.
