I have a Nortel 61c with 2 routes, one labeled local, the other ld. I need to have 2 phones built with local and tollfree access only. My NCOS 0 blocks all external. I figured if i used NCOS 1 on those lines (it is pointed to the local trunk). It would block ld...WRONG. the ONLY NCOS that blocks anything is 0. The RLI looks correct...am i missing something or is it an issue with my local circuit. Any suggestions?
