Call-By-Call Service Selection 
 

Definition  
Call-by-Call service selection (CBC) lets the user select a different type of service for each channel, such as INWATS channels and some OUTWATS channels within the same trunk group.
The following are the four main features provided through call-by-call (CBC):
 •   Foreign Exchange Non-ISDN Facility
This trunk type enables users to originate or terminate calls as if there was a local CS in the foreign (remote) central exchange office. Access to the foreign exchange (FX) is possible via LCR or trunk group access codes.
 •   Tie Trunk Non-ISDN Facility
This trunk type enables users to connect to a privately leased analog Tie Trunk network. Access for originating calls is possible through LCR. Terminating Tie Trunk calls are routed according to the called party number (CdPn).
 •   OUTWATS facility
This feature allows customers to place calls to certain areas at special lower rates.
 •   INWATS facility
This feature supports the 800 area code that provides callers toll-free access to the terminating party. This is a terminating only service.
