I need help programming the line ringing on this switch. Thanks

ITCM *#746*
Dial 54
Dial 1 for Direct or 2 for Delayed
Select lines (dial 01-06 or use B1-B6) and # after lines are selected.
Select station ports (dial 10-25 or use A1-A16) and * after station ports are selected.
Press ** speaker to end.

I don't know why you Installers don't take advantage of the Manual Download Center, There are thousands in there. The cost of a membership fee pays for itself on the first service call.
