Hello,
 
The pinout is like 1,2,4,5 you need to use LED and check the signal, connect the telco send with your receive, your receive wth the telco send.
 
you need to be sure about some parametres, the line code (HDB3 or other, the CRC4 is on or off, the impedance 75 or 120 if you are using CAT5 you need to configure 120 ohm.
 
the best way is to test all parametres if you don't now your telco's parametres.
 
Best Regards,

A T carrier cable is not the same as an ethernet cable. A T carrier  cable uses a real metal shielded RJ-45 and loosely twisted pair wire.  With most modern T carrier equipment, you can use a CAT-5 ethernet cable  instead of a real T carrier cable. A T-carrier crossover cable does not  have the same wiring pattern as a crossover ethernet cable. With an  older piece of equipment like the Matra, I would be tempted to purchase  a real T carrier crossover cable. This is covered in my book, by the way.
