More than one VDN always point to a vector. In addition, some vectors are linked to other vectors by the goto vector command or by the route-to command that points to a VDN. Before you delete or change a vector, identify all the VDNs and vectors that will be affected.

The list usage vector xxx command displays all the VDNs and vectors that send calls to vector xxx, where xxx is the assigned vector number.

For example, to delete vector 3, enter list usage vector 3 and press Enter to determine what other elements of the system send calls to vector 3.

The List Usage Report screen appears as follows:

list usage vector 3                                              Page 1

                        LIST USAGE REPORT

Used By
Vector               Vector Number         1                 Step 3
VDN                  VDN Number            58883

VDN 58883 points to vector 3. In addition, step 3 in vector 1 sends calls to vector 3. When you delete vector 3, change the vector and VDN to point to a different vector, or delete the vector and VDN.
