Re: Post RS Errors
 

I've put the 10dB attenuator on, it's lowered the downstream power levels to between 1 and 2 dBmV. Be interesting to see if anything else going to be done.

Re: Post RS Errors
 

So it's been a week since whatever was done to bring the SNR up a bit yet I'm still getting the Post RS errors. Not as many as before though.

Re: Post RS Errors
 

The power levels and snr are excellent, reset the rs errors counter and see what happens.

Re: Post RS Errors
 

I reset them yesterday. Seem to get a burst of them after a few hours.

Re: Post RS Errors
 

Has the modem reset at all during that period? Or have you rebooted it?

Re: Post RS Errors
 

Last time I rebooted the modem was after I put the attenuator on. There's been 1 T3 timeout since.

Re: Post RS Errors
 

So the post RS errors were cleared after the reset and no reset has occurred since?

Re: Post RS Errors
 

Yep, reset the counters after and also reset them yesterday. Haven't rebooted the modem since last week. Gone up a bit more since the last stat post.

Re: Post RS Errors
 

Mmm.

If these are causing a service problem and the same thing isn't being seen with the rest of the people on your tap I reckon you could do with being moved to another port in the cabinet.

If that doesn't sort it might need a repull - new cable between you and cabinet.

Re: Post RS Errors
 

Been sending more PM's back and to, to the person I'm dealing with on the VM forum. Looks as though they are going to arrange for another Superhub to be sent out. Don't know if it'll help but would at least rule it out. If not, I'll have to somehow see if they can arrange to do what Ignitionnet has suggested. Not quite sure how I'm going to approach that.

Re: Post RS Errors
 

When/if they send you another tech, then the tap change can be made. Important to get all this in your file notes. Ask the Forum Team member to do that.

Re: Post RS Errors
 

Ok, thanks. I presume when the tech was last out, he just moved it on the current tap point, rather than moving to another? The forum team member is waiting to hear back from an email she has sent to the tech who last came out, for an update. If she doesn't hear anything then she's going to arrange for a new Superhub to be sent out tomorrow. I don't know if it'll help though. Had a couple of dropouts overnight.

Re: Post RS Errors
 

Been a change of plan, it's been arranged for a Principal Technician to come on Tuesday. So without telling him how to do his job, would it be right for him to consider:

1. Moving to a different tap point
2. Check the condition of the coax cable and consider a repull if necessary
3. Maybe change the Superhub

Re: Post RS Errors
 

Is this fault service affecting?

Re: Post RS Errors
 

Well see that's the thing, I always seem to get full speed. Its not like I'm pushing for something to be done, the forum team member sent me a PM on Wednesday asking how things had been. I replied back that the SNR seemed to be ok but I was still getting the post rs errors. She sent an email to who she thought was the engineer who attended to get an update (turns out it was someone else), and they replied back, saying to book an engineer again. I'm just going along with what they are saying.
