Hi,
I've moved home and had FTTC (Zen 80/20) activated 2 weeks ago but my downstream sync (50.8) is much lower than predicted for line length (Range A 80 - 66.8, Range B 80 - 59).
I'm 300m from the cabinet (drop line comes via poles from cabinet so I can easily see the route and measure it), these are my current line stats:
Receive Direction Send Direction
Max. DSLAM throughput kbit/s 80000 20000
Min. DSLAM throughput kbit/s 128 128
Attainable throughput kbit/s 51057 20828
Current throughput kbit/s 50827 20000
Seamless rate adaptation off off
Latency fast fast
Impulse Noise Protection (INP) 0 0
G.INP off off
Signal-to-noise ratio dB 7 6
Bitswap on on
Line attenuation dB 15 16
Profile 17a
G.Vector off off
Carrier record A43 A43
BT checker, and spectrum images attached.
I've checked (and fixed) the wiring in the house, and tried through the filtered face plate, and direct via test socket with new microfilter, but this is the best I've managed to get. I've also done a quite line test and can't hear any noise.
Any ideas where to go next? Do I just live with it, or is it worth raising as a fault with Zen?
