My first post, but I have followed the forum for a while...
My HW set up, is a HG612 modem (running the SP08 firmware) connected to a huawei cab approximate 1,877m from the exchange.
I have the QOS turned off on the modem as I have QOS enabled on ubiquity ER-X router which connects via PPPOE to NowTV's Fab Fibre service
(I have just changed 10+ days ago) from an ECI modem, so as to get the line stats more easily.
When i first connected the HG612 my line stats were:
Max: Upstream rate = 7969 Kbps, Downstream rate = 45012 Kbps
Bearer: 0, Upstream rate = 7969 Kbps, Downstream rate = 32399 Kbps
Down Up
SNR (dB): 10.4 6.2
Attn(dB): 21.6 0.0
Pwr(dBm): 11.8 3.5
About week later after a re-sync they changed to
Max: Upstream rate = 6950 Kbps, Downstream rate = 45888 Kbps
Bearer: 0, Upstream rate = 6950 Kbps, Downstream rate = 32399 Kbps
due to resync retrain reason 1 which I assume is DLM intervention?
Down Up
SNR (dB): 10.9 6.1
Attn(dB): 21.6 0.0
Pwr(dBm): 11.9 2.0

I am new to reading these diagnostics, so my question is the downstream rate (32399) due to Banding by the ISP or due to DLM on my line ?
My ISP advertise an "average" of 36000 Kbps and my line is capable of 45064 so I am thinking banding, however the small drop downstream rate after the re-sync and cahnge to the pwr value makes me think DLM.
Essentially, I am just trying to figure out what the stats are telling me, any guidance the gurus can provide would me much appreciated.
