Have a mics with xc 6.1 software. loop card in slot 4 and ti is slot 3 combo card slot 2. has a PRI in it but I do not have the software keys so do not want to cold start or retemplate. the issue is I have busy out both cards, took out the loop card, moved the t1 card to slot 4 reset line data but when i go into line on each extension, I do not get an option for pri A, get B_C_D 1-23 but no A. have match up the system to another working 6.1 on all programing under services and system programming but seem not to get pri a to come up and this is on two cabinets from the same source. (purchase off ebay). trying not to lose the pri codes and reprogam. also came with 5 digit dn and changeing to 4 digit. not an issue. just the pri A kicking my butt...any suggestion.
