hi,

Yes, I agree.... 8000 eight-bit samples per second is 64000 bps or one DS-0 (PCM). (in TDM one time slot); time division
multiplexing is when 8000 eight-bit samples are taken from each timeslot every second. This should be clear (didn't said that it
wasn't ;) but... as far as I know, TDM bus transmit and receives PCM data to and from modem cards...

no shame, any correction?

No. Cable modem is not TDM ("time division multiplex") - that's ISDN/SDH
hierarchies, based on 56/64 Kbit DS0s.
