Dialed Number Identification Service on 800 Service (also known as INWATS 
Directed to DID trunks), is a service for use in conjunction with an ESP's voice
grade trunk (DID) circuit switched basic serving arrangement.  Incoming 800 
Service calls are terminated over DID trunks, thereby indicating the 800 number
that was dialed by the calling party.  The ESP knows the station number 
associated with each 800 number so when it receives the station number over 
the DID trunk it can identify the 800 number called.
