I'm working on some calculation software but need more understanding on (DOCSIS) signals with respect to optical WDM and narrow-/broadcasting. If've Googled blisters on my fingers but could not find a reasonable to-the-point explanation, so hopefully there's an expert among you who can help me a bit further. Some questions I have (lot of questions, but I'm describing architectures I can think of but may be never used in practice):
I am by no means a DOCSIS engineer, but have been working this config in the lab environment for some time. For some reason I cannot get the second group of modems to come on line at 8x4, instead they lock up at 4x4 or 5x4. I'm totally stumped. Any ideas and assistance that anyone can provide would be greatly appreciated. I am open to any and all suggestions. Please see the following config:
I'm working on a project and I want to block 5Mhz through 200Mhz so I can insert a new carrier. I've emailed a few companies and asked on-line, but so far... no luck..
I know it's not a regular filter that blocks the return, but if it works right.. could be a good size order. Any thoughts?
We have a Casa C3200 in our lab environment, with 1 modem connected to it (8 DS / 4 US channel bonding). We are sending traffic in both the US and DS directions for testing.
The DS direction seems to pass traffic fine with a latency average of about 4ms (up to around 300Mbps).
However, when sending US traffic the latency average is around 70ms (higher at higher US rates). We get some frames at 100ms+ at around 270Mbps.
I have a site with all D3 modems and have 24 frequencies of 1 cable leg running off the first 24 (controller Modular-Cable 5/1/0) on a MC3GX60V card. I have 3 x 8 bonding groups and all is working without issue. I have them set up under interface Cable 5/1/0 as you can see below. I wish to add another group of 8 to the same leg of cable and need to know how to go about doing this. If I put "downstream Modular-Cable 5/1/1 rf-channel 0-7" under "interface Cable5/1/0", then I can't figure out how to create the 8x bonding groups.
