upstream ofdma channels not locked

Can you see it on your(Cox) side? The upstream channels, however, only half of them lock (channels 1-4). Loss of FEC lock on NCP. used?) Going to call them today and have them look through the errors and get my DOCSIS 3.1 blue light back. … By properly … Brian Cox Support Forum Moderator. The modem indicates 3.1 / blue on the downstream but the upstream is showing 3.0 / green. The current levels provided by Comcast are 38 - 42 across the 4-upstream channels. Upstream (per upstream service group) 12 SC‐QAM and 2 OFDMA (up to 95 MHz each) Set Top Box Out‐of‐Band (OOB) SCTE 55‐1 SCTE 55‐2 Out‐of‐Band2 Narrowband Digital Forward (NDF) —one NDF channel per downstream service group Since I only have internet service this is probably my issue as well. It looks like you're new here. My frequencies are 477-677. Upstream power is in spec. Great infromation, thanks! Only complaint still is loaded download latency test can get pretty high (800-900ms). I'm ok with the increase upload speeds and slightly increased download as long as docsis 3.1 is in the works. Verifying DOCSIS3.1 Upstream OFDMA channel bonding across DOCSIS3.0 ATDMA channels. 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. 21 The downstream light does show blue on the front of the modem (indicating that DOCSIS 3.1 is being used for downstream). Acquire Downstream Channel: This should say "Locked", "OK" or similar. Generating in-channel and out-of-channel upstream and downstream DOCSIS 3.1 signals. Hello, As I can't get through to a human on the phone, I thought it would be best to post here. OFDMA subdivides a channel into smaller frequency allocations called resource units (RUs). I'm seeing ~340 mbps max download speeds when doing a controlled test from my laptop wired directly into the modem. I have the Netgear CM1150v Docsis 3.1 cable modem telephony and am curious about the downstream channels. Is Spectrum going to fix the Browser Flash player issue? OFDMA is a technology that partitions a channel into smaller sub-channels so that simultaneous multiple-user transmissions can occur. out of my modem's 32 channels?!? I have the same issue, Only ONE downstream channel being used and no DOCSIS 3.1 on upstream. Yep. Since I don’t see any OFDMA channels I’m assuming that’s your DOCSIS 3.0 modem not the CM1200. 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). Move CM’s service flows back to original BG. 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)? • 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 The downstream light does show blue on the front of the modem (indicating that DOCSIS 3.1 is being used for downstream). Pretty sure OP should have OFDM channel locked. 1 Locked 0, 255 159 690000000 Hz 6.5 dBmV 39.5 dB 1366 ~ 2729 1192634081 903871793 0 2 Not Locked 0, 255 0 0 Hz 4.9 dBmV 0.0 dB 0 ~ 4095 0 0 0 Upstream OFDMA Channels Download speed and upload speed are important factors when choosing the right cable modem for your needs. Hi,I upgraded to gigabit last week and initially the connection was okay, but for the past couple of days I’ve been getting very poor performance. 3 Agenda . Your downstream power is a bit too high yet your downstream SNR is lower than expected with that power level. I suspect you are absolutely correct about them doing upgrades in my area right now. Mine shows all 32 downstream channels being used now. Starting from Cisco IOS XE Everest 16.6.1 release, DOCSIS3.1 Upstream OFDMA channel can be bonded with DOCSIS3.0 ATDMA channel. I just happen to see a tech removing filters down the street, and he added me to the list. You will not be... Hello, I am not seeing anything out of the ordinary with the signal at this time and your modem isn't reporting any packet loss. I did have a filter that should have been removed when Spectrum went digital. Helpful thread! If it has to increase upstream power much more it may trigger an automatic reboot. Downstream Channels. My internet works fine, and my speed matches my tier (250 Mbps). Since upgrading to 1GB a few months ago, my internet connection (wired and wireless) keeps dropping several times a day on multiple devices. I would definitely call them. ; The first 2 checked wiring etc which is a fine. OFDM is locked on mine not on gigablast tier though, 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. Channels 1-31 are locked on, but I do not see any of the Docsis 3.1 frequencies allocated to the modem. Event Type Code: 1; Chan ID: 15 16; DSID: N/A; MAC Addr: N/A; OFDM/OFDMA Profile ID: N/A. 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). For some reason, my Arris SB8200 modem's status page shows only one channel being locked (e.g. Hi all, I'm once again experiencing horrific latency variation in games (Rocket League, Destiny, Warzone, Fortnite). A loss of FEC lock on one of the assigned downstream OFDM profiles of a channel. • DOCSIS 3.0 Data rate up to 320 Mbps with 8 upstream channel bonding • DOCSIS 3.1 Modulation: Multi-carrier OFDMA BPSK to 4096QAM • DOCSIS 3.1 Data rate Up to 700Mbps with 1 OFDMA 80MHz upstream channels • Frequency: 5-85 MHz • Upstream transmit Signal Level: +11 to 65 dBmV • Output return loss: >6dB NCP profile failure. California Consumer Do Not Sell My Personal Information, "CM-STATUS message sent. I appreciate the accurate response I get through this forum. Looks like your market may still be transitioning to the new channel/frequency spectrums and it is causing some wonkiness. Call Spectrum and request a technician for signal issues. The modem used to bond to all 4 channels, now it only bonds to 2 channels. If you want to get involved, click one of these buttons! 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). • 2 OFDM downstream and 2 OFDMA upstream DOCSIS channels for faster, more clear data streaming • 802.11ax Dual Band WiFi (AX6000) – 2.4GHz AX: 3x3 (Tx/Rx) 1024 QAM 40MHz, up to 0.9Gbps ®– 5GHz AX: 3x3 (Tx/Rx) 1024 QAM 80MHz, up to 1.8Gbps • Backwards compatible with 802.11a/b/ •g/n/ac WiFi Docsis 3.1 and EuroDOCSIS 3.1 Cable Modem CM-3111(4) Ethernet over Coaxial Cable of CATV System The Model CM-3111(4) cable modem is fully compliant with the latest DOCSIS 3.1 specification as published by CableLabs® and is capable of delivering downstream cable speeds of up to 3.6 Gbps by using 2 Orthogonal Frequency-Division Multiplexing (OFDM) downstream channels … 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). 16. Channel 32 is not locked on. If the user wants to utilize non-best effort flows, it is recommended to bond the OFDMA channel with one or more ATDMA channels. 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.

Thanks for looking into this. My SNR and power levels are all well within acceptable ranges and I bond to all 4 channels upstream. NCP) indicates to the DOCSIS 3.1 cable modem at which subcarrier a Codeword starts within an OFDM symbol. When I lost DOCSIS 3.1, dl speeds decreased 30-40%. Hello, We are experiencing multiple drop outs per hour / per day. It still would only lock (2) of the (4) upstream channels. Tried a couple power cycles, then a factory reset. Interestingly, upstream light is green (indicating DOCSIS 3.0 for upstream/send)? Learn more about upstream and downstream channels here. Online gaming is becoming unplayable. My question would be: Is it common that not all the channels lock? ". Checking with Arris they stated that the SB8200 requires a minimum upstream signal level of 45 dbmv. Interestingly, upstream light is green (indicating DOCSIS 3.0 for upstream/send)? Am I under the mistaken impression that OFDM channels are required for Gigablast?
