I may not be able to list down all the good billing systems, but few of them are listed below: After a call is made or you can say a usage is generated by the end customer, the mediation system gathers usage data from the network switch and builds a call-detail record (CDR).This CDR must contain A party number and B party number, the start and end date & times. To rate the call, the CDR is examined to see if the call is, for example, a 800 number, a local call that is covered by a local-area calling plan, international call or a toll call.

Since I don't want to make matters worse than they are now, I haven't uninstalled the network card yet.

When I put the CD in the computer, and after getting the Starting installation wizard message, a software setup screen then comes up with Select components.2 boxes with check marks on them. I told her that if we don't get this darn thing resolved before Sunday night, I'll just return it to Comcast and try another one. If the modem and the computer are within reasonable proximity, connect them with an ethernet cable.

Information such as the time of the call was placed and city code or country codes are used to calculate the rate for the call.

Once each call is rated, this information is stored until the invoice is run, usually once a month.

When the invoice is run, other nonusage charges, such as discounts or monthly fees, can be applied to the bill or sometime called invoice.

There could be rating time discount or billing time discount, different payments done by the customers, different adjustments given, all this information contributes in final invoice generation.

I thought that at first, perhaps, a virus and/or malware somehow got by and changed/altered the wireless settings, though the antivirus software and Malwarebytes software is up-to-date and is showing no problems. One of these may be doing strange things with the connection. If that does not work it could be a newtork card driver issue. However, before you do that I would advise you to make sure that you have the driver disc for that netcard (or for the notebook if it is an internal Wi Fi netcard), because Windows will often not have built-in drivers for any given netcard.

One way to restore networking, especially wireless, is to go into control panel, system and delete the network card. Since you mentioned that this notebook had previously been setup for multiple wireless profiles, my suggestion would be to delete all existing wireless profiles and see if that allows you to then create a new profile for the Comcast gateway.

Telecom Billing is a process of collecting usage, aggregating it, applying required usage and rental charges and finally generating invoices for the customers.

Telecom Billing process also includes receiving and recording payments from the customers.

Examples include Phone, Radio, Television and Internet.
