[asterisk-users] ISDN PRI configuration

[Carlos Alvarez]

I am not Kevin, but I'll tell you that I will not EVER use an Ethernet
cable for T1 again.  Kevin and I have discussed this at length, and the
"should work" plays out poorly in the real world, or at least mine.  I've
had it be fine, and had major problems.  I can't even find a pattern to it,
like length of cable.

In a colo cabinet that was direct-connected to a carrier, it worked great
for years and then one day...no T1.  Just gone.  Go down there and put in a
real T1 cable, came right up, still up years later.

I usually make my own, since they are so expensive to buy.  I just connect
the four needed pins, pretty easy to do if you're not trying to stuff all
eight wires into the connector.
