[Asterisk-Users] Results of an incorrect crossover pinout??

[Geoff Manning]

Say I had a crossover cable that connected a Mitel SX200 to a TE110P and the
pinout was done as such:

1 - 4
2 - 5
5 - 1
4 - 2

(the 5 and 4 are transposed on the left side)

Instead of the proper way of:

1 - 4 
2 - 5 
4 - 1 
5 - 2 

What would the results be? We have had the former as our cabling for a few
months and the connection has been fine. Slip errors here and there. But we
have had major issues the last few days where there were excessive slip
errors culminating in the Mitel taking it's T1 card offline. 

1) Could the pinouts I have been using have actually worked? Or am I smoking
crack?

2) Could that have been the source of my problem? If so why didn't it
surface earlier? 

We put a new cable in place today so only time will tell if it fixes it (it
seems to have major alarms on the Mitel every 12 hours or so). I'm just
curious.

Thanks,
Geoff
