Are power levels on upstream low?
Hi, I have a Virgin Hub 3 and I have experienced a couple of disconnections over the weekend. I believe I have a FTTC and then Coaxial from the cabinet to my property. I had a similar problem back in June where a moderator of this forum kindly arranged an engineer to visit and they stabilised my connection. The engineer replaced some component in my terminal box but did comment there was other components which appeared old and may need replacing in the future. Anyway, I just wanted to post my stats and have a sense check from someone more knowledgeable than myself to tell me if my hub stats are an early indication of any problems. Here are my upstream figures (the Power signals were consistently about 42dBmV a month ago. The figures below are consistent and have been like this over the last 48 hours although sometimes channel 3 modulation says "32 qam" rather than the 64 it says now): Upstream bonded channels Channel Frequency (Hz) Power (dBmV) Symbol Rate (ksps) Modulation Channel ID 1 30100000 30 5120 64 qam 12 2 23600000 28.5 5120 64 qam 13 3 36600000 30 5120 64 qam 11 4 43100000 30 5120 64 qam 10 5 49599996 31.5 5120 64 qam 9 Upstream bonded channels Channel Channel Type T1 Timeouts T2 Timeouts T3 Timeouts T4 Timeouts 1 ATDMA 0 0 0 0 2 ATDMA 0 0 0 0 3 ATDMA 0 0 0 0 4 ATDMA 0 0 0 0 5 ATDMA 0 0 0 0 Here are my downstream figures, although I think these are fine: Downstream bonded channels Channel Frequency (Hz) Power (dBmV) SNR (dB) Modulation Channel ID 1 331000000 2.2 38 256 qam 25 2 139000000 6.4 38 256 qam 1 3 147000000 5.8 38 256 qam 2 4 155000000 5.6 40 256 qam 3 5 163000000 5.4 38 256 qam 4 6 171000000 5.3 38 256 qam 5 7 179000000 5.1 38 256 qam 6 8 187000000 5 38 256 qam 7 9 195000000 4.9 40 256 qam 8 10 203000000 4.5 38 256 qam 9 11 211000000 4.5 38 256 qam 10 12 219000000 4.3 40 256 qam 11 13 227000000 3.7 38 256 qam 12 14 235000000 3.7 38 256 qam 13 15 307000000 1.9 38 256 qam 22 16 315000000 2.4 38 256 qam 23 17 323000000 2.5 38 256 qam 24 18 339000000 1.5 38 256 qam 26 19 347000000 0.7 38 256 qam 27 20 355000000 0.7 38 256 qam 28 21 363000000 1.2 38 256 qam 29 22 371000000 1.2 38 256 qam 30 23 379000000 1.2 38 256 qam 31 24 387000000 0.5 38 256 qam 32 Downstream bonded channels Channel Locked Status RxMER (dB) Pre RS Errors Post RS Errors 1 Locked 38.9 10 0 2 Locked 38.9 2 0 3 Locked 38.9 11 0 4 Locked 40.3 9 0 5 Locked 38.9 11 0 6 Locked 38.9 8 0 7 Locked 38.6 9 0 8 Locked 38.6 5 0 9 Locked 40.9 6 0 10 Locked 38.6 14 0 11 Locked 38.9 8 0 12 Locked 40.3 9 0 13 Locked 38.9 8 0 14 Locked 38.9 7 0 15 Locked 38.6 4 0 16 Locked 38.9 12 0 17 Locked 38.6 11 0 18 Locked 38.9 8 0 19 Locked 38.6 6 0 20 Locked 38.9 6 0 21 Locked 38.9 8 0 22 Locked 38.6 7 0 23 Locked 38.9 19 0 24 Locked 38.6 7 0 TL;DR = Do my upstream power signals look dangrously low and are they degraded enough to warrant an engineer to come out?
