SYSTEM OUTLINE
Centralized Billing
Centralized Billing is a function that transmits billing information at each office to the center office within
the same network through the common signaling channels of No. 7 CCIS.
To transmit the own billing information of the local office to center office, or transfer the billing informa-
tion from other local offices to the center office, SMDR is required for each office. SMDR can be accom-
modated in the Center Office through LAN connection/RS-232C connection.
