Centralized Billing - NEC NEAX 2000 IPS Reference Manual

Chapter 14 Common Channel Inter-Office Signaling (CCIS)

Centralized Billing

This feature is used to collect billing information from each office within the network and direct
it to the associated center office. Billing information is then forwarded to the central billing
centers via RS232C interfaces.
Service Conditions
1. The Centralized Billing system is composed of local office, tandem office, and center office.
2. The NEAX 2000 IPS is generally used as a local office; however, it can be used as a center office
for centralized billing if all the PBXs within the network are NEAX 2000 IPS.
3. When the NEAX 2000 IPS is used as a center office, the billing information is sent to a SMDR
system using the NEAX 2400 format and an AP00.
4. When a NEAX 2400 IPX is used as a center office, either the Sub Line or the My Line number
can be selected by system programming to be sent to the SMDR terminal. When the NEAX 2000
IPS is used as a center office, only the My Line number can be sent to the SMDR terminal. When
a call is originated from a station (Station A) of a local office (without AP00), via a COT of a center
office (with AP00), a message is sent to the center office from the local office via CCIS. According
to the station number of the calling party, the AP00 of the center office generates billing
information to the SMDR terminal.
5. Maximum digits of station number is as follows:
Local office/Tandem office
using Internal SMDR: six digits
using AP00 : four digits (if fifth digit of all stations uses a comman leading digit then five
digits)
Center office: four digits (if fifth digit of all stations uses a comman leading digit then five digits)
6. Center office
Maximum of eight local offices can be accommodated.
Maximum of 3,600 calls per hour can be received. If the center office exceeds 3600, billing
information is stored at local office.
