August 2006
For Generic 602.20
2-87 Switch settings for printed circuit packs
For this type of ringing, the appropriate multiparty line ringing type defined in Overlay
CNFG (CP) in response to prompt MPRT, is MFR2 (see NTP 297-3601-311, Data
Modification Manual).
Settings: 1 = ON, 0 = OFF, - = NOT APPLICABLE. Ignore 0 and 1 stenciled on the circuit
board; use the ON position stenciled on the DIP switches. For the NT6X30CA, switch 8
must be set to the on position.
