I was wondering does anybody know what the normal normal interval is for a DLM forced re-sync on a good line

I currently have  the following stats from my HG612 after 7 days and am hoping to get a lower interleave downstream

It is clear that your line is connected via a Huawei equipped cabinet. I suspect that G.Inp has not yet been implemented on your circuit.

You just really need to be patient and play the waiting game.  :)

Am I misunderstanding something? G.INP is enabled on his line Burakkucat?

Code: [Select]
Interleave depth:          16      1
INP:                       47.00      0
G.INP:                     Enabled

That is the result of speed reading and looking out for Bearer 0 & Bearer 1 header lines.  :-[  Now where is my brown paper bag? :paperbag:

Here's what happened to me over the last few days. The jumps in speed are pretty obvious
Sep 7 - line finally fixed and DLM reset
Sep 9 - G.INP enabled on downstream
Sep 15 -DLM increases upstream

DLM is unlikely to decrease the level of interleave, and why is it bothering you,there is no delay added, looking at your stats it looks like you are provisioned on a 80/20 product but it's capped to 40/10 but AgR:40055.74   10057.90 also whether interleave is 16 or 8 i seriously doubt you would notice the difference

8ms is quite noticable?

For a start the 8  Doesn't represent delay so it isn't 8ms
