To achieve Gigablast or Ultimate speeds, a DOCSIS 3.1 modem is required. Day 1 of activation, all four upstream channels bonded. I'm currently testing both Netgear and SA Docsis 3.0 modems with IOS 12.2.33(SCC3) and I cant seem to get it working right :| I'm seeing modems registering as MTC-modems (/UB) with only one US (with two in the configured bonding group). See modem teaming . After upgrading to the DPC3008, I have only 1 downstream channel and 1 upstream channel. For ultra-high-definition (UHD) television, only three or four channels would fit on a 36 MHz transponder. The SWM-8 uses 2.3Mhz, while your cable modem upstream is 23Mhz+. used?) The first step is simple. If I remove the US attribute masks I can get the modems to Channel bonding can increase your internet speed by nearly 50%. Is my modem broken? NOTE 1: A typical setup for Internet access consist of connecting one computer or a Wi-Fi router directly to the cable modem. Upstream bonding was only working on one channel. Connecting a Wi-Fi router to the SB8200 is recommended when there are multiple client devices in the home network. These are classified into two types, upstream and downstream. Day 1 of activation, all four upstream channels bonded. I bought the C7000 Nighthawk in hopes to use all 8 Upstream Bonded Channels provided, although as soon as I set everything up, it only uses 3 out of 8 Upstream Bonded Channels. Ideally, it should be as close to zero as possible. Hello, I just bought a C7000 Nighthawk to replace my SBG 6700ac due to internet drops. You can use either Wi-Fi or Ethernet. Restrictions: This feature is supported only on one upstream bonding group under a MAC domain. ... Posted January 25, 2015. You'll have some downstream channels and also some upstream channels. For the traffic above, two downstream channels and one upstream channel are required, whereas a typical CMTS configuration has a 4:1 or 6:1 upstream:downstream port ratio, the inverse of what is needed. Its probably more likely that your area is not congested enough to warrant them opening all 4 upstream channels. You can view bonding by logging into the modem.Verifying the Upstream Channel Bonding ConfigurationUse the following show commands to verify the upstream channel bonding configuration:•show cable mac-domain upstream-service-group•show cable fiber … After taking a look at the modems signals, it shows I only now have 1 upstream bonded channel, when before I had 8; which 4 were active. Channel bonding provides cable operators with a flexible way to significantly increase downstream speeds to a maximum of 160 Mbps, and upstream throughput up to … A 16-QAM 3.2 MHz upstream channel will deliver about 8-9 Mbps net. What about the CMTS? Please Reload/Refresh this Page for a new reading 5 dBmV . Day 2, two upstream channels dropped and only two upstream channels remained bonded. Only one channel upstream, how to get more? Has anybody succeeded in combining Cable Modem steering with Upstream Bonding ? Screen shot of the channel statistics attached. Instead, they use only one connection at a time. A 64-QAM 6 MHz downstream will deliver about 28 Mbps net throughput. I've had TWC send "refresh signals" to … This question is about "Motorola MB7420 upstream channels", with Time Warner Cable internet and apps. However, the power level on 1 of the upstream is 0. And it is not his job to do so. When multiple upstream bonding groups are configured under a MAC domain, the utilization is unfair. My modem is a fairly new Cisco DPC3008. Verify all cable connections and try resetting the modem. Note: This port is a LAN Gigabit Ethernet port. I know there is one solution on the Comcast forums. Day 3, one more upstream channel dropped and only one upstream channel remained bonded. Hello, I have been working on a 16x4 configuration with a uBR10k in a lab using docsis 3.0 modems. Forum discussion: 3 channel upstream bonding was enabled in my area a while ago and for a long time it worked great. 24x8 channel bonding. DOCSIS 3.0 gains bandwidth by bonding together 6MHz channels, each of which can carry about 38Mbps. I used to have Comcast's 105 Mbs service, which uses 4 bonded channels downstream and 2 bonded channels upstream. Additionally, it is possible to bond multiple cellular links for an aggregated wireless bonded link. The other answers here are vastly more complete than I could hope to be. (8x4 modems) However, it appears that the modems will only bond with one upstream channel, and that channel will vary from modem to modem so its clear they're all being used. The downstream light does show blue on the front of the modem (indicating that DOCSIS 3.1 is being used for downstream). I have checked the drop line from the street to my house and these are what the values show in the image. None - multiple upstream channel is in use: Blinking Blue: Negotiating multiple upstream bonded channels. Provides internet access to a single device. Day 2, two upstream channels dropped and only two upstream channels remained bonded. Connect your computer to the first DSL line. Power Level The Downstream Power Level reading is a snapshot taken at the time this page was requested. Once the modem was activated, it bonded to all 24 downstream channels (yay! Each one has separate power levels and SNR listed for it. This means if you have a download speed of up to 6 Mbps, you could potentially get up to 12 Mbps with channel bonding. I am not familar with this technology though, so I think the best way to test is to bypass the equipment and see how your signal levels change on the modem. Hello, This is my first post I've been having issues with my internet connection for a while now specificaly packet losses at peak times which would hit 25-30%, and during the day they linger around 5-10%. It has 8 downstream and 4 upstream channels. Neither Microsoft nor macOS computers can bond two different connections on their own. Downstream Bonding Channel Value Channel ID 11. Forum discussion: My sb6183 used to bond with 4 upstream channels before I got Maxx upgrade to 200 MB. Also, the signal to noise ratio is 0 on one of the downstream channels (between 38.3 and 39.0 on all others.) My Motorola MB7420 upstream front panel light is green indicating it is only connected on one channel. Channels bonded can be wired links such as a T-1 or DSL line . One of my colleagues, Frank Eichenlaub, has seen upstream CNR degraded by as much as 16 dB because of misaligned fiber links! This feature balances the utilization only if there is one upstream channel bonding group configured per MAC domain. When downstream DOCSIS channels are bonded, the per-channel maximum power also drops.
