Re: [connectivity] Low margin and high ping issues. help please! Yea, the first thing I was going to ask is if they could switch my pair, and go from there.
Again not knowing much about how dsl let alone telcom works is literally every pair in the trunk "live" to the point of where (at the pole) they could just take my pair and connect them to a non-used "live" pair or does more need to be done at the dslam/co/etc?
The only reason I ask is because if it was as simply as just switching the pair at the pole I would be (in my computer knowledge) dumbfounded as to how actual provisioning works then. Does it go by something at the co? dslam? username? (highly doubt) mac address? I would have to say something tied to the modem information only because if you could just swap lines at the pole then every line is theoretically "live" to transfer phone/dsl signal if something tries sending that particular signal.
Like Tom says, the amount of tech that goes into getting 2 copper lines to transmit actual signal and getting it to the right point just seems WOW to me. |

Provisioning entails much more: assigning port on DSLAM, setting up ATM, setting speed, setting up user account in RADIUS server, making sure there is adequate backhaul capacity and probably lots more.
Swapping pair is much simpler. First of all probably will not be switched all the way back to the CO but to a cross connect box. High pair count cable exit the CO and get split and re split at cross connect boxes. Those are the file cabinet size green boxes you see by the side of the road. If tech finds a bad circuit section, either through manual inspection or MLT they will find an unused cable pair and use it.
If there is a bad section and there are spare pairs it is an easy task. Most likely will not affect the DSLAM or anything within the CO itself.
