8.2.3.4. Service Remarks 
Note the following remarks for both features.
- The systems must be connected using one of the following protocols:
- Cornet_NQ
- and DPNSS1
- You may not assign the following station devices in a call pickup group:
- Attendant console
- The feature is not checked via the dongle.
- You must provide for the digit analysis result "OWNNODE" in the digit analysis and you must enter the parameter PNODECD in the central system data.
- If you use an open numbering plan with NPI unknown, the "OWNNODE" of the remote system is configured to the digit analysis result TIE.
- If you use an open numbering plan with NPI E164 or PNP, the OWNNODE of the remote system does not appear in the digit analysis because the node code of the system is completed to international format or Level 2 format.
- If you use a closed numbering plan, the "OWNNODE" of the remote system is configured to NETW with appropriate destination number.
- After a call is picked up, the system performs path optimization if needed.
