DMS-500 telnet session I captured years ago. This one shows me in C7TRKMEM table—editing SS7 trunk members, turning VERIFY OFF, and bulk-deleting old CIC entries during a route cleanup. The blue screen can take you right back to long nights in the switchroom. #DMS500 #TelecomHistory #SS7 #SwitchTech
