Re: Modem for better sync

In reply to a post by j0hn83:
If the SNRM is 6dB then it's likely your brothers line is simply interleaved.
Interleaving/INP has a side effect of the max attainable being exaggerated.

If the (downstream) SNRM is around 9-10dB (rough calculation) then your brothers line is banded/capped by the DLM.


Thank you

I saw he was on fast path as it was a line item in the BT smart hub interface. Must be DLM for him then.

I must have a much cleaner line, hopefully that won't change with the move to plusnet.

Do you know if DLM allows a 3dB SNRM on a clean line that is on a ECI cab?

My HH5 rebooted itself every 4-10 days (apparently its a thing with them) but the TP-Link is solid.

It doesn't, no.

This is due to ReTx/G.INP not working on ECI cabinets at the moment.

My suspicion is that when SRA is rolled out they may allow 3dB SNRM targets on ECI kit.

It's looking like they have given up completely on G.INP on ECI cabinets.

Bt to plusnet happened today

Seems I gained a fair bit in max connect rate, not sure why, but having said that my actual connect speed is lower than my 55Mbps on bt

Ps Iím getting an Authenticaton error as my account is not yet activated but I am connected and synced

Plusnet
Current Rate (Kbps) 15042 51963
Max Rate (Kbps) 15111 63001
SNR Margin (dB) 6.1 6.3
Line Attenuation (dB) 29.7 13.3
Errors (Pkts) 0 0

BT
Current Rate (Kbps) 9995 54998
Max Rate (Kbps) 15321 56475
SNR Margin (dB) 9.4 6.5
Line Attenuation (dB) 29.8 13.3

Hopefully with my stable line I will get up to my max connect rate. That would be worth the switch considering Iíve been at 50Mbps for so long

The DLM is reset when you migrate.

You are now interleaved which artificially exaggerates the attainable on FTTC.

If the line remains stable it will return to as it was.

Thanks that makes sense now.

I remembered being interleaved on BT and my pings went up but my max rate stayed the same around 55Mbps but my actual sync dropped to around 47Mbps. Not sure why it's different this time but hopefully all things being equal I'll not loose any speed on PN.

Thank you
