Frank,
It gets better (which is sad) in the case of Charter if a customer=20
ordered voice and data they were given a normal Moto SB for Internet=20
data and a separate Arris eMTA (with no CPEs allowed other than the TA=20
and the Ethernet port disabled) for voice. The channels they were using =
for voice even terminated on a different CMTS altogether.
