    Were using an older Rev B EnableIT 860 kit on telephone wiring and wanted to know what other things affect throughput. Wire distance is over 1.2 miles.

    The 860 Rev B DIP switches 2/4 in default position: 53.6 Mb/s Full Duplex

    The 860 Rev B DIP switches 2/4 in interleave and 9db (respectively): 33.6 Mb/s Full Duplex
    As we can see the difference is about 20Mb if we change the default settings

    Customer Support:
    That's awesome as Telephone wiring for data tops out at around 10Mb/s over 328ft.
    CAT rated cabling is better suited for high frequency transmissions especially at distance.
    Dan:
    ahhh
    Customer Support:
    You could switch to a CAT rated cabling if possible
    Dan:
    We have to use the telephone poles and Sprint is a little picky about what we use. Or more accurately what they will put up
    Customer Support:
    The actual environment of the telephone wiring install could be introducing interference factors. The signal could be bleeding out and reducing it effective throughput or there could be nearby wire pairs that are bleeding over their signaling into your telephone wire pair
    Customer Support:
    Right - Sprint rather lease you a circuit instead.
    Customer Support:
    Other factors could be the continuity of the telephone pair - the more connection points the more possible interference can be introduced
    Dan:
    What if we ran another pair, do you have a unit that can bridge the two connections? Or would we need to get another set and use a smart switch?
    Dan:
    Yes - we lease a circuit from Sprint but, it doesn't go to the CO it is a direct connection between the two houses.
    Dan:
    We had it shot(tested)
    Customer Support:
    The latter is more cost effective. We do have a multiport concentrator that does bond ports together, however it is more cost effective if you have more ports.
    Dan:
    Got it. So increasing the throughput is out the window? Not even with a newer unit?
    Customer Support:
    Correct as the Telephone wire is the limiting factor without bonding
    an:
    So then the suggestion is to run another line and get another set of 860lre's and use a smart switch to bond two ports together?
    Customer Support:
    Correct that is what we would recommend for increasing your throughput. Make sure the pairs have enough separation from each other so that no interference occurs with 2 separate 860 kis running close together
    Customer Support:
    Make sense?
    Dan:
    Separation on the poles?
    Dan:
    As in make sure they are insulated well enough
    Customer Support:
    No not necessarily, just insulated from eachother
    Customer Support:
    Let sprint know there is high speed signaling on the pairs
    Customer Support:
    If outdoors on a pole they probably have them pretty well shielded
    Customer Support:
    just make sure they don't give you a second pair inside the same shielded cabling - as that will work but it has the possibably of degrading the signaling of both kits
    Dan:
    ahh good to know, because I think that we have an extra pair just chilling in the telco box outside
    Customer Support:
    ok
    Dan:
    So that would be a bad idea
    Customer Support:
    You could try it to see what performance you get
    Customer Support:
    That would be a good first start and add a new pair if needed to get more
    Dan:
    Ok thanks for your time, I appreciate it.
    Customer Support:
    Your very welcome Dan.
