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.
We have +30 Casa C3200 running at different sites, and they are (through a different ISP) connected with BGP in a VPN (full mesh) network.
Two other sites where we have core routers are also connected to the VPN (to provide the internet access).
The issue we've been having is rather strange, and i wonder if anyone else use the Casa C3200 with BGP (or done in the past), and have experience with the following issue?
