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.
