The CTP can not be mapped (i.e., it has no contained potential CTPs). This indicates that an SNC/crossconnect can be used to connect the G.805 TCP of the CTP to the connection point of another CTP/FTP. This only applies to CTPs that connect on their server side and are related to the containing PTP/FTP on their client side.

The FTP can not be mapped on the server side (i.e., it has no contained potential CTPs on the server side). This indicates that an SNC/crossconnect can be used to connect the G.805 TCP of the FTP to the connection point of another CTP/FTP. This only applies to FTPs that connect on their server side and do not support IM (Inverse Multiplexing).
