that the ATA takes on a separate slice of bandwidth from the Internet
connection and therefore can't be squelched by heavy downloading, but no
such luck. Nir tells me all the above solutions suffer from jitter, and
this one is no exception
DOCS*I*S :)
If the device hooks up directly to the cable, just like a cable modem or
a set-top box, then it doesn't take a slice off your (for sake of
example) 1.5M Internet package. In essence, to the ATA, your cable modem
is just like your neighbor's cable modem, since you're all on shared media.
You might be sharing a DOCSIS downstream RF channel (38MBit/s) with
other subscribers, either Internet or phone ones. The CMTS may,
following your ATA's registration, redirect it to a downstream RF
channel dedicated for phone services, on which the devices-per-channel
rate will be carefully managed to guarantee QoS... or it may not :) In
any case, those DOCSIS specifics are only relevant between your ATA and
your area's CMTS; from the CMTS onwards, it might be some entirely
different protocol.
