Can some one tell me , looking at this that interleaved has come back on . Think it happen after the problems the other week .

Thanks for your help .
Interleaving takes place between your equipment and the exchange, if you lost sync or tried to reboot to restore service then the DLM is likely to have switched it back on.
You'll need to ask support to have it switched off.
The FEC are at 0 so I would have said that interleave is still off,support will know for definite.
If it is on it's not corrected anything yet.
I'm with Steve. If you do a BT speed test, what profile do you have?
Results Image not loaded
Test1 comprises of Best Effort Test: -provides background information.
Download Speed
6739 Kbps
0 Kbps 7150 Kbps
Max Achievable Speed
Download speedachieved during the test was - 6739 Kbps
For your connection, the acceptable range of speedsis 2000-7150 Kbps.
IP Profile for your line is - 7150 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is -
These figures represent the ratio while sententiously passing Sub BE, Normal BE and Priority BE marked traffic.
The results of this test will vary depending on the way your ISP has decided to use these traffic classes.
Which make of router are you using ?
speed touch st585
If you Telnet into the router and get the stats it should tell you if the path is interleaved.
CMD > telnet > router IP >password > show adsl (or similar )
CLI command for 585v6 to show interleave status plus other adsl stats is > adsl info
With a profile of 7150, interleaving isn't on.
Ok guys thank for your help , i will just have to wait for pings to settle down again .

??? it is perfectly possible to have a max profile of 7150 and have an interleaved line, the statement that you cannot have a synch above 7616 with interleaving is false.
I had 448/8128 and a line profile of 7150 for several months , and have seen plenty of others with the same .
But there's also no FEC errors, Dorset.

Agreed, and I do not believe that line is interleaved but so many times we see the old chestnut about profile/interleaving which misleads people.

It should also be pointed out that whilst BTw state that applying interleaving shouldn't reduce your line speed, it does reduce the maximum line rate achievable from 8128kbps to 7616kbps due to the additional overhead required for check bytes.
Note: although BT state 7616 is maximum sync speed with interleaving, many instances of higher sync speeds have been reported by users. This is dependent upon your router being able to support S=1/2 mode which effectively combines two RS code words into a larger logical code word of 510 bytes (ANSI T1.413).
Yup, it was certainly set in stone when I started out that you couldn't sync at 8128 and be interleaved, which is why we need extra info to get to the reality. Life was easier with fixed rate connections!
