The Physical DS3 Port object defines a port (physical interface) on a DS3 communications card, providing TDM connectivity into the PSTN.
Each Physical DS3 Port object is a child of an Adaptor object with adaptor type TD2000 DS3 TDM Adaptor.
In the EMS System Explorer, the name shown for each Physical DS3 Port indicates
For example, 'Physical DS3 Port (Shelf B, Slot 3, Port 11)'.
To start using DS3 ports, you need to do the following:
