A fast question.
I want to connect two asterisk pbx via isdn PRI(i know there is iax2 and is more fast and simple…but i want to test PRI for knowledge).
I have a doubt about the crossover cable needed
I use this combination
pin1 pin2 pin3 pin4 pin5 pin6 pin7 pin8 SIDEA Orange/white ORANGE white/green BLUE WHITE/BLUE GREEN white/brown brown SIDEB BLUE white/blue white/green WHITE/ORANGE ORANGE GREEN white/brown brown
for the correct color order i’ve refer to this
So pin 1 of sideA is pin4 of SIDEB
and pin2 of sideA is pin5 of SIDEB
pin 4 of sideB is pin1 of sideA
pin 5 of sideB is pin2 of sideA
But in this forum/mailing list an user said
1 – 5
2 – 4
4 – 2
5 – 1
What did you suggest to use?
With my combination I obtain a lot of hdlc errors, span1 down, etc
I also tried a “pre-made” cable from amazon with same results.
