Telephony Billing Manager 1.2 (TBM 1.2) is a group of software applications created for collecting the information regarding the telephonic traffic through a switching center (Nortel Networks Meridian1/ Succession) and traffic analyses in order to highlight the costs of using the telephonic network through detailed reports on the: dialed number, duration, calls cost, calls cost summaries, calls cost totals on departments, services and entire corporation.
Telephony Billing Manager has the following software components:

	ComWatch application, for data collecting through the PC serial port, filtering, analyzing, processing and saving to database;
	TelecomBilling application, that is a graphical interface made to provide an easy  tool for querying of the current database and the archive database and viewing,  exporting, printing and saving reports;
	DatabaseTools software utility which helps the user to archive the data from the current database (CDR) by transferring it to the archive database (Arh), deleting useless data and also to call then compact & repair function for the selected database.
	CDR – current database, in this database the ComWatch application  writes the information regarding the incoming and outgoing calls;
	Arh – archive database, which contains the information moved from CDR database.

The information regarding the calls, named Call Detail Recording (CDR) are collected by the ComWatch application through the PC serial port, they are real-time processed and saved to the current database, that means that ComWatch application have to be permanently running.
Depending of the hardware capabilities of the PC on which TBM is running a big size of the current database can have a negative impact on the speed of data processing of the queries. To avoid such a situation TBM contains an archive database, which will be used to store the less used call’s data transferred from the current database (CDR) using DatabaseTools software utility. After this process of transferring data from CDR to Arh the information is first stored in Arh database and then deleted from CDR database.
TBM has his own tools for viewing, saving, exporting and printing and does not need any other application for achieving these goals. Otherwise, the existence of any applications on the PC which is running the TBM, theoretically does not affect the good functioning of the TBM applications.
