Hi folks,
Around 4 months ago, I moved my FTTC line to a different property, sticking with Zen. My line is pretty stable but towards the lower end of the speed estimates.
I've been logging my stats up to MyDSLWebStats since the line went live and things generally seem OK;
- SNR ranges from 5.8-6.2dB downstream and 6.1-7.4dB upstream
- Errored Seconds per Hour tend to be 0-2
- Attenuation constant 16.4dB
- hlog shows a nice smooth exponential curve
- Rarely resyncs - most resyncs have been because i've powercycled the modem and I rarely do this. There's only been one DLM initiated resync in the last few months (which I think was due to my SNR being above target)
- Roughly 450m from the cabinet, by road rather than as the crow files
However, my actual sync speed is around 10-12mbit below the modem's 'attainable' speed stat and my interleaving is set at what seems to be weirdly high - 1,432 down and 363 up. It also seems a little odd that even though the line has been active for over 4 months and i'm connected to a Huawei cabinet i've not had G.INP applied or had the target SNR decreased from 6 dB. I know this can take a little bit of time to apply, but poking around a few other threads on here it seems most people have had it applied by the 4 month mark on a new line.
I'm not sure if i'm misreading the stats and my line is actually performing well, but the high interleaving seems a little off to me given the stability of the line. I would appreciate if anyone can offer any insight! I'm currently using a Zyxel VMG1312-B10D in bridge mode, having switched to that from a HG612 around 2 months ago. The modem is connected directly to the master socket, there's no internal phone wiring connected. I did try performing a quiet line test and I heard a bit of static, however this could be because i'm using a cheap Argos Value cordless phone - unfortunately I don't have any other phones to test with! I did ask Zen about this too, but they mentioned that things seem to be all OK from their side without elaborating exactly what they checked.
Stats are available on MyDSLWebStats under the same username I use here. There is a G next to my name, but that's from when I was uploading under this username from the previous property, whose FTTC line was G.INP enabled!
Many thanks
