125.4.1 CHANGE-KNMAT

Changes the node connection matrix, which consists of two independent parts: the restrict connection component and the station number modification component. An entry is addressed with NPI, LEVEL, ONNO (or ONNOL) and DNNO (or DNNOL).

All combinations ONNO/ONNOL and DNNO/DNNOL are considered. For example, if all node number parameters are present incommand, the modification is done for:

ONNO - DNNO
ONNO - DNNOL
ONNOL - DNNO
ONNOL - DNNOL

In the station number modification component, the delete function is implemented by means of NUMEXT=***** or NUMRED=*****.

In the restrict connection component, the delete function is implemented by means of CONN=A.

NPI, ONNOL, DNNOL, MODCON, NUMEXT and NUMRED are valid only for the station number modification component.

CONN is valid only for the restrict connection component.

LEVEL, ONNO and DNNO are valid for both components.

If an entry can no longer be made in the node connection matrix owing to insufficient memory (see cross-references: AMO DIMSU), an error message is displayed.

MODCON is only an attribute of an entry in the node connection matrix and is therefore only valid in combination with an entry. This means that an empty entry with MODCON=NOMOD is not possible (NUMEXT or NUMRED have to be specified or have to exist in this case too)

Examples

Single-level network (level 0 only). The station numbering plan UNKNOWN is to be changed by adding the extension 91 for connections from the home node to all other nodes in the network for all kind of traffic conditions.

Input:

CHANGE-KNMAT:UNKNOWN,0,,OWN,,ROW,,,91;

Two-level network (levels 0, 1). Connections from the originating node number 100 to destination nodes with the numbers 120 to 200 on level 0 are to be permitted, and the extension 722 is to be added to station numbers signaled in this context in the ISDN numbering plan. This extension should only apply to outgoing connections. The modification takes effect between the nodes xx-100 and xx-120 to xx-200 (xx being any level 1 region).

Input:

CHANGE-KNMAT:ISDN,0,100,,120&&200,,A,OUT,722;

If the extension 89 is to be added to outgoing connections from level 1 region number 15 to region number 16 in addition to the above example, the following command must be entered:

CHANGE-KNMAT ISDN,1,15,,16,,A,OUT,89;

Once both commands have been entered, a dual extension is applied between 15-100 and 16-120 to 16-200: 722 is added to begin with, and then 89, with the result that the station number 4711 is converted to 897224711. Between 15-100 and 15-120 the resultant modified station number would be 7224711; no modification would take place between 15-100 and 15-119.

On level 2, the international element of the station number (exit code, prefix and country code) are to be reduced in the ISDN numbering plan in incoming terminal traffic and transit traffic from Central Office (CO) region specified by fictitious level 2 region number 1 (e.g. by AMO TDCSU, parameter NNO=1-0-0).

Input:

CHANGE-KNMAT:ISDN,2,1,,,ROW,,IN&TRANSI,,00049;

Connections from originating region 25 to destination region 92 on level 1 are to be denied.. Any station number modifications already entered in the PRIVATE numbering plan for these connections are to be deleted.

Input:

CHANGE-KNMAT:PRIVATE,1,25,,92,,D,,*****,*****;

Configuration of a replacement number between a local station with extension number suppression (SSTNO=ONLYEXT) defined in the own virtual node 17 and a Central Office specified by a fictitious node number 100:

CHANGE-SDAT:STNO=2100,TYP=DATA,SSTNO=ONLYEXT;

CHANGE-KNMAT:ISDN,0,17,,100,,,OUT&REPEXT,4989722*0;

The asterisk character (*) in NUMEXT has a special meaning in combination with MODCON=REPEXT. It means that, if the calling station has the attribute ONLYEXT, the calling extension number is replaced by the part right of the asterisk. Afterwards, the resulting extension number is extended by the part left of the asterix independant of the attribute ONLYEXT.

Please note that the format of NUMEXT corresponds to the format defined by AMO KNFOR for the destination node (here international format, i.e. no entry in AMO KNFOR or the entry INTERNAT for DNNO=100). The codes (49, 89, 722) can be read by means of the virtual node number of the local subscribers (17) from the KNDEF table.

In the example above the calling number 3111 is converted into the new calling number 49897223111 (no ONLYEXT, i.e. normal number extension). The calling extension 2100 (ONLYEXT) is sent to the Central Office as 49897220 (that means the number was replaced and extended).
