There are also a lot of errors and critical messages. Can you see it on your(Cox) side? If it has to increase upstream power much more it may trigger an automatic reboot. 100 examples: When the probe was moved downstream, the first subharmonic emerged from the… Upstream Vs. An upstream V is formed by an obstruction in the water that creates a V that points upstream. Event Type Code: 1; Chan ID: 33 ; DSID: N/A; MAC Addr: N/A; OFDM/OFDMA Profile ID: N/A. Channels 1-31 are locked on, but I do not see any of the Docsis 3.1 frequencies allocated to the modem. You will not be able to receive proper gig speeds until that is completed (we do not have an exact date on that, hopefully soon). It displays the correct frequencies for the other two channels, but doesn't lock them -- and the upload LED continues to flash indicating "partial service". There should always be at least 1 channel acquired with a DOCSIS 1.1 or 2.0 modem. This system uses an injection‐locking technique to enhance the usable bandwidth by making stable channel states. Upstream power levels are not good... should be settling in a couple points lower. 4G is the fourth generation of broadband cellular network technology, succeeding 3G, and preceding 5G.A 4G system must provide capabilities defined by ITU in IMT Advanced.Potential and current applications include amended mobile web access, IP telephony, gaming services, high-definition mobile TV, video conferencing, and 3D television.. By subdividing the channel, parallel transmissions of small frames to multiple users happen simultaneously. I'm seeing ~340 mbps max download speeds when doing a controlled test from my laptop wired directly into the modem. 16. My SNR and power levels are all well within acceptable ranges and I bond to all 4 channels upstream. I would expect to see SNR of 43-45dB with a 9-10dB power level. Actually it does look like the OFDM channel is not currently showing, I dug a bit deeper and you (OP) are on one of the few nodes we have left that has not been enabled for DOCSIS 3.1. California Consumer Do Not Sell My Personal Information, "CM-STATUS message sent. Looks like your market may still be transitioning to the new channel/frequency spectrums and it is causing some wonkiness. Since I don’t see any OFDMA channels I’m assuming that’s your DOCSIS 3.0 modem not the CM1200. Tech was out once and said the issue was on our end. Verifying DOCSIS3.1 Upstream OFDMA channel bonding across DOCSIS3.0 ATDMA channels. The first-release Long Term … Hello, As I can't get through to a human on the phone, I thought it would be best to post here. I am on the 100Mbps plan and in the Irmo, SC area (not sure if this is why upstream is limited to DOCSIS 3.0). Tried a couple power cycles, then a factory reset. This means your modem found the frequency with which to receive information from the internet. My question would be: Is it common that not all the channels lock? Downstream Channels. Need The Option to Unmark Accepted Answers If Solutions Don't Work. Call Spectrum and request a technician for signal issues. My ISP is comcast. Once the water had receded, the extent of the damage became clear. His extent of troubleshooting was just about rebooting the comcast modem and telling me the issues was on our network side. The modem indicates 3.1 / blue on the downstream but the upstream is showing 3.0 / green. Learn more about upstream and downstream channels here. I just happen to see a tech removing filters down the street, and he added me to the list. I've had 3 engineers out over the last 6 months. If the user wants to utilize non-best effort flows, it is recommended to bond the OFDMA channel with one or more ATDMA channels. NCP profile failure. When I lost DOCSIS 3.1, dl speeds decreased 30-40%. I checked my modem page on my CM1000 and I'm not seeing any OFDM channels locked. Interestingly, upstream light is green (indicating DOCSIS 3.0 for upstream/send)? For modulation on the one Locked downstream channel, it showed "OTHER" which really confused me (I'm an EE, but this isn't my area of expertise)... Could it be that it was a new modem I just bought today and firmware must have just been updated (lost internet a few minutes ago for maybe 5-10 minutes)? Mine shows all 32 downstream channels being used now. ; The first 2 checked wiring etc which is a fine. ABSTRACT We propose a scalable support WDM‐based orthogonal frequency division multiple access‐passive optical network uplink transmission system using an injection‐locked Fabry–Perot laser diode (IL‐FP‐LD). Move CM's service flows to RBG/NB or suspend RF from BG. Is Spectrum going to fix the Browser Flash player issue? Great infromation, thanks! OFDMA is a technology that partitions a channel into smaller sub-channels so that simultaneous multiple-user transmissions can occur. DS Chan ID: 32; Previous Profile: ; New Profile: 1 2 . DS OFDM profile failure. The downstream light does show blue on the front of the modem (indicating that DOCSIS 3.1 is being used for downstream). OFDMA subdivides a channel into smaller frequency allocations called resource units (RUs). Those 3.0 channels max out around 38mbps throughput each.

Upstream power levels are not good... should be settling in a couple points lower. 4G is the fourth generation of broadband cellular network technology, succeeding 3G, and preceding 5G.A 4G system must provide capabilities defined by ITU in IMT Advanced.Potential and current applications include amended mobile web access, IP telephony, gaming services, high-definition mobile TV, video conferencing, and 3D television.. By subdividing the channel, parallel transmissions of small frames to multiple users happen simultaneously. I'm seeing ~340 mbps max download speeds when doing a controlled test from my laptop wired directly into the modem. 16. My SNR and power levels are all well within acceptable ranges and I bond to all 4 channels upstream. I would expect to see SNR of 43-45dB with a 9-10dB power level. Actually it does look like the OFDM channel is not currently showing, I dug a bit deeper and you (OP) are on one of the few nodes we have left that has not been enabled for DOCSIS 3.1. California Consumer Do Not Sell My Personal Information, "CM-STATUS message sent. Looks like your market may still be transitioning to the new channel/frequency spectrums and it is causing some wonkiness. Since I don’t see any OFDMA channels I’m assuming that’s your DOCSIS 3.0 modem not the CM1200. Tech was out once and said the issue was on our end. Verifying DOCSIS3.1 Upstream OFDMA channel bonding across DOCSIS3.0 ATDMA channels. The first-release Long Term … Hello, As I can't get through to a human on the phone, I thought it would be best to post here. I am on the 100Mbps plan and in the Irmo, SC area (not sure if this is why upstream is limited to DOCSIS 3.0). Tried a couple power cycles, then a factory reset. This means your modem found the frequency with which to receive information from the internet. My question would be: Is it common that not all the channels lock? Downstream Channels. Need The Option to Unmark Accepted Answers If Solutions Don't Work. Call Spectrum and request a technician for signal issues. My ISP is comcast. Once the water had receded, the extent of the damage became clear. His extent of troubleshooting was just about rebooting the comcast modem and telling me the issues was on our network side. The modem indicates 3.1 / blue on the downstream but the upstream is showing 3.0 / green. Learn more about upstream and downstream channels here. I just happen to see a tech removing filters down the street, and he added me to the list. I've had 3 engineers out over the last 6 months. If the user wants to utilize non-best effort flows, it is recommended to bond the OFDMA channel with one or more ATDMA channels. NCP profile failure. When I lost DOCSIS 3.1, dl speeds decreased 30-40%. I checked my modem page on my CM1000 and I'm not seeing any OFDM channels locked. Interestingly, upstream light is green (indicating DOCSIS 3.0 for upstream/send)? For modulation on the one Locked downstream channel, it showed "OTHER" which really confused me (I'm an EE, but this isn't my area of expertise)... Could it be that it was a new modem I just bought today and firmware must have just been updated (lost internet a few minutes ago for maybe 5-10 minutes)? Mine shows all 32 downstream channels being used now. ; The first 2 checked wiring etc which is a fine. ABSTRACT We propose a scalable support WDM‐based orthogonal frequency division multiple access‐passive optical network uplink transmission system using an injection‐locked Fabry–Perot laser diode (IL‐FP‐LD). Move CM's service flows to RBG/NB or suspend RF from BG. Is Spectrum going to fix the Browser Flash player issue? Great infromation, thanks! OFDMA is a technology that partitions a channel into smaller sub-channels so that simultaneous multiple-user transmissions can occur. DS Chan ID: 32; Previous Profile: ; New Profile: 1 2 . DS OFDM profile failure. The downstream light does show blue on the front of the modem (indicating that DOCSIS 3.1 is being used for downstream). OFDMA subdivides a channel into smaller frequency allocations called resource units (RUs). Those 3.0 channels max out around 38mbps throughput each. Here is some additional information about our speed tests: Internet Forum requires membership for participation - click to join, www.cox.com/.../understanding-speed-test-results.html. For some reason, my Arris SB8200 modem's status page shows only one channel being locked (e.g. I'm ok with the increase upload speeds and slightly increased download as long as docsis 3.1 is in the works. The other half (5-8) won't lock. ;CM-MAC=14:c0:3e:0b:da:a5;CMTS-MAC=00:17:10:86:59:de;CM-QOS=1.1;CM-VER=3.1;", "MDD message timeout;CM-MAC=14:c0:3e:0b:da:a5;CMTS-MAC=00:17:10:86:59:de;CM-QOS=1.1;CM-VER=3.1;", "DS profile assignment change. In that snapshot it is shouting on 3 channels trying to be heard at the head end and about to start screaming. The CM1150V will only bond (2) upstream channels. Generating in-channel and out-of-channel upstream and downstream DOCSIS 3.1 signals. Since I only have internet service this is probably my issue as well. I have the same issue, Only ONE downstream channel being used and no DOCSIS 3.1 on upstream. • 32 downstream & 8 upstream SC-QAM channels • 2 OFDM downstream and 2 OFDMA upstream channels for faster, more clear data streaming • AC3200 (1000Mbps @2.4GHz with 1024-QAM support + 2200Mbps @5GHz 11ac) † • Simultaneous dual-band WiFi—Tx/Rx 4x4 (2.4GHz) + 4x4 (5GHz) • Beamforming+—Focuses WiFi signals for Helpful thread!
