In my message #6589 I erroneously stated:

"The HDT environment, incidentally, can be likened to the cable operators' head end environment, made up of their combined CMTS (Cable Modem Termination System) and RF modulation/demodulation fields. Have you heard or seen anything resembling a digital head end standard?"

While I had intended editing this earlier, I forgot to get to it and posted it as is. The HDT, as it stands, is not unique to the digital FTTP/FTTH/FTTN platforms. HDTs are also used in cable tv head ends. Only, when used in cable facilities they are responsible for multiplexing the various services (e.g., voice, data, digital video, etc.) and then sends the content through the RF mod/demod gear prior to hitting the backbone.

All-digital setups, on the other hand, need not go through the digital to analog RF (D/A and A/D) conversions.
