We had 4 CO Line from LCOB8 card. Now we have disconnected 3rd and 4th CO Lines but when we press "0", on the LCD screen it still shows Line 003 or Line 004 which no longer exist. System is Lg Aria 300 and I am using LDK Pc Admin software.
In PGM141 set the CO line Goroup (COG) to 29 or higher for CO line 3 and 4.
CO line 1 and 2 will remain in CO line Goroup (COG) 1, that is the active COG.
