NOTICE ON PROGRAMMING
• If the number of received digits does not coincide with the number of digits of station num-
ber, assign the digit addition/deletion by CM35 Y=17.
• If received digits do not coincide with the station number, assign the digit conversion by
CM76.
• If an incoming call must be transferred to Attendant Console by station busy, restriction of
termination or receiving unassigned number, assign the transfer destination by CM51 Y=03
or 06.
• If the Answer Signal from PSTN exists for DOD connection, assign the Answer Signal by
CM35 Y=04.
• DOD with Multi Frequency Compelled (MFC)-R2 Signaling is performed by using LCR fea-
ture.
OUTLINE OF MFC-R2 SIGNALING
The MFC-R2 Signaling is based on interregister signal of system R2 recommended by ITU-T.
This signaling is performed end-to-end by 2-out-of-6 in-band multi frequency codes with forward
and backward compelled signaling. The MFC-R2 is designed to use six (6) signaling frequencies
in the forward or backward direction.
The system can provide the following functions through the MFC-R2 Signaling.
• Direct Inward Dialing (DID)
• Direct Outward Dialing (DOD)
• Automatic Number Identification (ANI)*
* ANI is the function to inform the station number of calling party to the Public Switching Tele-
phone Network (PSTN) for message accounting.
The table on the following pages shows the frequency combination for MFC Signals and the func-
tions available in each country.
