Putting EBIF and Tru2way to the test

That's been changing in the last few years, but not necessarily because of EBIF and tru2way. The introduction of VoIP has brought some attention to the upstream.

"But you can't just assume, 'Well, I rolled out VoIP, my return path has to be good,'" said Ron Shanks, who is in charge of video solutions at JDSU. VoIP is in a different frequency range than EBIF or tru2way traffic would be.

Andrew Sachs, Volicon's senior director of marketing for cable/IPTV, said: "You have to hook up a stream analyzer and capture the stream. If you get the PIDs through ingress grooming, it's good, it'll show up on the set-top box."
