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 U NIVERGE 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 IPS.
3. When the U NIVERGE 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 U NIVERGE 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
U NIVERGE 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 (SMDR over IP is not supported)
using AP00 : four digits (if fifth digit of all stations uses a common leading digit then five
digits)
Center office:
using Internal SMDR: six digits
using AP00:four digits (if fifth digit of all stations uses a common leading digit then five
digits)
