Been a while since I've needed to get the DEP. (Had it five years ago or so).
I have about 200 pages of printouts, but if somebody has something a little more lean and current I'd certainly appreciate that.
in our little plant a cisco cmts ubr7246 with NPE-G1 12.3(23) and an old uBR-MC28u (EuroDOCSIS 2) Linecard is working fine until now we connected the AVM Fritzbox 6660 to it.
The Router´s LED is blinking and in GUI Downstream Channel found ist displayed but nothing more.
In CMTS the modem isn´t there.
So i think the Box doesn´t come in Upstream Ranging but doesn´t know why.
Maybe some of you have the same problem ? Maybe it isn´t downward compatible.
All other Boxes are perfectly online. And tested other 6660 (the same problem).
Can anyone explain to me if seeing 50+ volt AC on a coax line (with multimeter BLACK to ground RED to coax connected to docsis equipment) at the demarcation is a problem that will cause signal drop outs? None of the equipment we use has a 3 prong plug and most consumer electronics don't either so I would expect to see these readings since all of the 2 prong equipment on that circuit would be looking for the shortest patch to ground.
