Public number

This command sets the public directory numbers for the 32 public number groups.

Furthermore this number is used to build up the public number that is sent out to the line as A (calling) or B (called/connected) number in cases where the internal number is not subscribed in the PSTN-net.

The numbers are used in applications for which the public number and/or the length of the public number must be known.

The number is also used in applications for which the internal extension numbers in the public network must be known. The extension numbers will then be built by taking the corresponding public number from the table (see command 1030 Public number group Public Number Group) and adding the internal directory number to the programmed number.

Example:

Programmed number: |  | Directory number: |  | Result: |
81100 |  | 205 |  | 81100205 |

Only in case of MFE-signalling the number will be built by replacing the last digits in the programmed number by the internal extension number. So please make sure you add as many trailing digits to the public number as are necessary to get the requested constant number length (6 or 7 digits).

Example:

The PTT specifies the public number to be 688 and 7 digits to be sent on a request to the public network.

Programmed number: |  | Directory number: |  | Result: |
6880000 |  | 4721 |  | 6884721 |
6880000 |  | 77 |  | 6880077 |

Public number:

Up to 16 digits in PRF.NUMB format representing the public number (with or without area code) to be dialled for getting access to this trunk from the public network. Only digits 0-9 are valid.

Type:

The following number types are possible:

'UNKN' = |  | 00h: |  | Unknown number (extension number) |
'INT' = |  | 01h: |  | International number |
'NAT' = |  | 02h: |  | National number |
'NET' = |  | 03h: |  | Network-specific number |
'SUB' = |  | 04h: |  | Subscriber number |
