5.36.2.2. Feature Principles 
- When you activate this feature, a station number is only unique if combined with a node code. Station numbers for multiple assignment continue to be configured in the AMO WABE with the digit analysis result STN .
- Stations can be reached in a virtual node with their station number, even without a node code.
- Idle terminals display the station number without the node code. Exception: SIP end points. These show the node code in the idle status.
- The display format for the station number in ringing or call status can be set individually for each customer (ISDN, PNP and unknown). This setting then applies to all stations in the entire physical node.
- Overlapping station numbers (10, 100, 1000) should be configured on the basis of DPLN groups.
- The node code and station number may not exceed 6 characters in length. This yields a maximum station number length of 12 digits.
