GENERAL INFORMATION FOR CCIS
4. NETWORK CONFIGURATION
With application of No. 7 CCIS added to the PBX, a network of multiple functions as if it were a single PBX.
Since calls can be freely transferred between one PBX and another, most of the existing station services can be ap-
plied to inter-PBX call connections.
Further, using the CENTRALIZED BILLING-CCIS service and the CENTRALIZED SYSTEM MANAGEMENT
REPORT-CCIS service, billing information and fault information can be processed at one center point instead of
processing at each PBX concerned.
Figure 2-4 shows an example of PBX interoffice network for CCIS Digital Line, and Figure 2-5 shows an example
of network configuration for CCIS Analog Line.
