I am having a hard time understanding what the above means. I am statting the cards on a remote Opt. 11C PBX (25.4) and when I stat card 4 I get an NPR006. I then statted the T1 in LD 60 and it's on loop 4. Does that mean the card in slot four in this PBX contains the T1 card? When I tried building a phone on 4-0 I got an SCH121 (loop not specified in config as terminal loop). Please let me know if I'm on the right track here. Thanks all.
