Chapter 14 Common Channel Inter-Office Signaling (CCIS)

Centralized Call Accounting/Billing Systems

Standard tie line networks require independent call accounting / billing equipment for each node in the network. This results in a costly investment of peripheral equipment, higher maintenance costs, and the need to service this equipment at each node.

In a CCIS network, it is not necessary to purchase independent call accounting / billing equipment for each node in the network. One call accounting / billing system can be centrally located, connected to any one system in the network, and the intelligent CCIS network will transmit the SMDR data from each system in the network over the D-channel to the designated centralized collection point, as shown in the following diagram. This increases reliability by minimizing hardware requirements, simplifies call costing data analysis, and provides a large reduction in operation costs.
