Hi, Digium's E400P has RJ45 conector and my E1 link has BNC concetor. Could someone tell me the cable pinouts to make this conection? thanks Eduardo

IIRC the impedance for telco is >specified at 600 ohms @ 1MHz, whereas for CAT5 the impedance is actually > T1s are always 100-110ohm, E1s are the same when on pairs, and 75ohm on coax. Only analogue pairs are terminated at 600ohm, and no line can actually be greater than 120*PI (about 377) ohms - that is the impedance of free space. Fudgy 600ohm stuff works at audio frequencies, but you have to treat the line properly as a t...
