DFMT

Directory Number Format

Format

Function

The parameter states the format, that is, the exact quantity of directory number digits in the interface between the interception computer and the system. The directory number format can be determined by the miniformats (if any) of the interception computer, or by the maximum length of the directory number.

If for example, the interception computer requires 4 digits and the maximum length of the directory number is 3 digits, then the format will be set to 4 digits. If the interception computer requires at least 4 digits and the maximum length of the directory number is 5 digits, then the format is set to 5 digits.

The directory number format can be set to 20 digits since the maximum length of a network number is 20 digits.

If there are directory numbers with fewer digits than the indicated format, these are right-justified and filled to the left with the filler character up to the indicated format of the Private Branch Exchange (PBX). For example, number 123 is sent as 0123 to the interception computer if the filler character was set to character 0, and the DFMT was set to 4.

If the interception computer sends a directory number beginning with one or more filler characters, these will be deleted in the subsequent processing in the PBX. For example, 0123 will be processed as 123 in the PBX if the filler character was set to character 0.

Example

• The directory number format is 4 digits.
