Incoming Digit Conversion

Incoming Digit Conversion is used to convert received digits into an unrelated (but dialable) local number. This might be done to manipulate a DID block, or to re-route calls to a different extension. IDC only applies to Direct Inward Dialing (DID) routes.

Use LD 49 to print, add, change, delete, or move Incoming DID Digit Conversion (IDC) data.

New Flexible Code Restriction (NFCR) and Incoming Digit Conversion (IDCA) must be allowed (both YES) in the Customer Data Block - LD 15, FCR_DATA. Set MAXT and DCMX (maximum number of NFCR and IDC tables) to say 100 each.

In the Route Data Block (LD 16), assign an IDC number by setting IDC YES, DCNO and NDNO (day and night IDC tree number) to the IDC defined in LD 49. Remember: A PBX without a console is always in night mode.

Print a route (RDB) in LD 21, or change it in LD 16. Check the following IDC prompts:

IDC yes          Use digit conversion for this route
DCNO 0-254       Day mode IDC tree number
NDNO 0-254       Night mode IDC tree number
DEXT (no)/yes    Display pre-conversion (dialed) digits

Define, change, or print an IDC tree, DCNO, in LD 49. At the IDGT prompt  (incoming digits to be converted), enter the DN (or DN range) to be converted. The DN(s) to be converted is output on the next line, and the user enters the internal DN after the colon.

Below is a sample print out of IDC 2 - incomming digit 0 will be routed to DN 3613
