I would be grateful for some advice. My FTTC line has been 100% stable at 85 Max down and 24 up for the past 2 years on an 80/20 profile. Over the past couple of months, BTOR has been installing a second PCP box. Last Friday, I walked past the site and three guys were working in the 2 PCP boxes and on an underground cable. When I got home, I found that my FTTC had suffered a brief disconnect and it was showing a DSL carrier but no internet connection. I walked back to the PCP and one of the guys offered to take a look. Twenty minurtes later, I got a call to say that he had reversed a jumper and everything should be OK. Yes and no - I got the internet connection back but at a max speed of 68Mbps with a downstream SNR of 4 and lots of errors.
This morning, I powered down my Fritz!Box. The FTTC speed has fallen to 66 but the downstream SNR has increased to 6. I have called Zen and they have run quote an invasive line test unquote and everything tests OK. They now want me to do the usual test from the Test Socket. I have 'no' for the moment as I have no reason to suspect that anything is wrong with my in house set up.
I am hoping now that the SNR has downstream increased to 6 that the profile will recover in time. My connection is currently showing 66581/18507, Latency FAST/FAST, G.INP OFF, INP OFF, SNR 6/6, Bitswap ON/ON and Line Attenuation 13/13.
The error rate is beginning to fall. After 3 hours it is showing:
Fritz!Box 22ES 0 Many Errors(SES), CRC 0.12/min Last 15 Mins 1
Central Exc 14ES 10 Many Errors(SES), CRC 0.31/min Last 15 Mins 0
Is there anything else that I should be doing/checking other than being patient?
