The DSL side of the splitter is straight into an RJ45 socket with the modem plugged directly into the socket


The Voice side of the splitter goes into a voice distribution board with cat5 to all of the BT sockets around the house. It appears that the voice cables are reversed but the data cables are correct.


Voice now has no static, but I'm seeing all these FECs on the Data side.







Would have thought it was strange for a structured cable house to have BT jacks installed rather than just two RJ45s per outlet. 



They ran two Cat5E to each phone endpoint, one Grey cable and one Blue.


They only wired the Grey cable to BT phone jacks and left the blue cabled unconnected.


At the patch panel they used a telco distribution board for all of the phone jacks with no xDSL spliter which I've now corrected.

coffeebaron: What do you mean voice cables reversed?


The Phone side of the xDSL splitter has been wired




Blue (xdsl) -> White (house)


White (xdsl)  -> Blue (house)





That's fine. Won't make any difference now days.



Chorus has spent $1.4 billion on making their xDSL broadband network faster and even more now as they are upgrading their rural Conklins. If your still stuck on ADSL or VDSL, why not spend $195 on a master filter install to make sure you are getting the most out of your connection?

Your SNR is riding low, upon resyncing it will adjust back to normal.


13FEC a second is still a little high, but being that  your now riding so low this typically will cause higher errors. Considering you have gone up from 10FEC a second it could affect you more.






key note: wording of could, this is not a CRC error, so there is no retransmit. however the modem does need to compute more error corrections which intail could induce delays such at peak load.
