I was going through the packetcable multimedia specs. I came across "Upstream drop classifiers". Can someone let me know why this may be used in the filed?
We are looking for small cable cos that presently bill manually or use OTS (Off the shelf) billing solutions to bill their customers and have the burning desire but lack the resources to purchase or build and deploy a fully functional cable video/data/voip billing system.
we have a few Arris C4, but in this new espansion, we find very good prices for Cisco uBR10K with PRE4 and MC20x20 RF Cards,
does anyone have both, to tell me the pros and cons of Cisco compare with Arris C4? We are using for VOICE, the DxQOS od C4
to create the separeted flows to voice, the Cisco (at the datasheet) tells that works the same, but i have doubts.
Hi,
I turn on old CMTS recently. The first week work correctly, but today completely stupefied.
Modems have not logged in. Only few pieces is visible on CMTS. Besides has status "Ranging missed"
I have upgrade firmware 4.3.1 to 4.3.307
I change modulation in DS from QAM265 to QAM64 and in US from QAM16 to QPSK,
but it did not help.
In side RF is all OK.
What else can I do?

I am curious if anyone can explain the difference between the SNR number calculated for the CMTS port and the SNR for each individual modem on that port. I have run across a few ports where the number per modem is drastically different than the SNR for the port itself. On the CMTS it would be the difference in running the show cable noise command versus show cable modem phy command.
I have even looked at the average over time for the port and the average per modem for the same time period and they too show a large
Is there a recommended guard band between upstream channels ?
IE would a 1.6 mhz wide channel at 22 mhz upstream require a guard
if there was another channel at 24 mhz with a 1.6 mhz wide setting ?
Maybe there is a handy Docsis chart somewhere ?
