Does anybody have any pinouts for an Option 11C T-1 Amphenol style connector to DB15 CSU ? The Nortel P/N is NTBK04AA and it is described as a 1.544 Mbyte Carrier Cable. Thanks.

if your not using a csu, vio/green pair to 1-3 on the db15. vio bro to 9-11 on the db 15, that will go back to pins 1-2 4-5 on the rj45 from the provider, in your t1 cable, short, vio/gre to vio/bro. and short gre/vio to gre/brown. enll the t1 in 60, it should come up, rel wronge mobe, then hold a yellow alarm.. that tells you that your layer 1 is correct and "up" to a loop back. your trunks will not come up but the card face should go green and then yellow.
