Title: Discrepancy between GEA Test and Modem information??
Post by: Interceptor121 on March 28, 2017, 01:37:04 PM
I have asked the provider to perform a GEA test and those are the results

est Outcome    Pass
Test Outcome Code    GTC_FTTC_SERVICE_0001
Description    GEA service test completed and no fault found but unable to check for customer equipment connected to modem.
Main Fault Location    OK
Sync Status    In Sync
Downstream Speed    40.7 Mbps
Upstream Speed    8.5 Mbps
Appointment Required    N
Fault Report Advised    N
NTE Power Status    PowerOn
Voice Line Test Result    Pass
Bridge Tap    Not Detected
Radio Frequency Ingress    Not Detected
Repetitive Electrical Impulse Noise    Not Detected
Cross Talk    Not Detected
Estimated Line Length In Metres    687.7
Upstream Rate Assessment    Low
Downstream Rate Assessment    Reasonable
Interference Pattern    Not Detected
Service Impact    No Impact Observed
Home Wiring Problem    Not Detected
Downstream Policing Discard Rate    0.0
Customer Traffic Level    Upstream and Downstream Traffic Detected
Technology    VDSL
Profile Name    0.128M-40M Downstream, Retransmission Low - 0.128M-10M Upstream, Error Protection Off

Looking at this I have 0.128-40M and GINP on there have no been any retrains since the first connection

Looking at the modem stats however there is only bearer 0 and hence no GINP and sync speed is 40673 this does not reconcile with the Profile on the GEA test

Any ideas what is going on?

Most likely the GEA test is reporting the configured profile but the actual live setting, and I guess your modem doesnt support g.inp?

My modem supports GINP and I was on it until I changed provider

I am currently on fastpath D=1 and delay=0 though

I did not turn anything off at the switch it and there have been no retrains of any sort since

I have an FTTC line that is on a GINP enabled cab, and in the past has had GINP enabled, but since last DLM reset some 70+ days ago it's been on fastpath.
I also have another FTTC, that one is also on fastpath.

Neither line has breached the red threshold for errors so DLM is doing nothing.

I do not think GINP is enabled unless the line needs it......

Sheepie that is what I thought but then why is the profile set to retransmission low?
I have opened a ticket with Plusnet let's see

I would assume that the profile info is out of date, nothing more to it than that. Plusnet don't normally put new customers on 40/10, they sell 40/2 and 80/20 packages.

I just had a resync (by DLM) and it enabled G.INP on my "new" line that only went live 8 days ago. As this is a 40/2 connection it was getting virtually no error seconds per day but DLM still decided to enable G.INP (straight from being fastpath, it was never interleaved).

Yet the line that I had DLM reset done on 11th Jan is still fastpath, and that one is always in "amber" for errored seconds per day, so could probably do with G.INP.

I opened a ticket with plusnet and today at 8:50 I had a resync, now GINP is active and the sync speed has gone up to 44186 from 40672
However when I do a speedtest on BT wholesale the IP profile shows still the old 39.37 mbps....

This is really confusing

I wonder what plusnet did to enable G.INP? When I ask my ISP (Zen) they do not seem to be able to control or request anything except a DLM reset and they will only do that if there is a fault.

Plusnet did nothing. DLM triggered a re-sync. Now the sync speed is higher but the profile still misaligned

The IP profile (http://www.kitz.co.uk/adsl/IPprofile.htm#IP_profile_calculated) is set to a percentage of the sync speed. I believe it will go up automatically but Plusnet might be able to speed things up for you.

Well it should have gone up the day after the re-sync but it looks like the profile is stuck now

I thought the IP profile is not used if you've been migrated to GEA backhaul as the subject suggests

BT wholesale also has a GEA link in each exchange and plusnet uses BT wholesale so yes it is used.

IP profile is used and mine should report as 42.72 with throughputs higher than 41mbps instead am at 38mbps so am loosing 3mbps or 8% for no reason. Also my upload is crap and 2 mbps lower than the estimates though this has nothing to do with the profile

Plusnet told me all is OK with the line but I said how can it be if the profile is capped to 40M whilst the sync rate is over 44M and reopened the ticket
Today I lost the PPPoE connection but not the VDSL and now I am on 42.72 IP Profile with speeds over 41 mbps
Looks like someone has changed the profile manually and all is good now

The results that Plusnet get when performing a GEA test always seem to be out of date.  I'm not certain if its just a Plusnet thing or if it applies to all ISPs.

I reported it on their forums last week because what they were telling me did not tie up with reality and was several weeks out of date.  Unfortunately it appears to have been ignored.

Looks like two weeks out of date on average
