The Digicom Win Modem PCI V.90 CTR21 is a modem that transfers data at 56 kilobytes per second. It is supported by the V.90 technology. In this technology, the modem assumes that one end of the modem connection is purely based in digital telephone network. Such networks are used by ISPs and organizations to provide them with remote access. The V.90 assumption is designed to take advantage pg high-speed digital connections. As such, the modem accelerates data downstream from the servers to the host computer at 56kbps. Unlike analog modems, the Digicom Win Modem PCI V.90 CTR21 encodes the downstream data rather than modulating it as the analog modems do. This modem transfers data in an asymmetrical manner, such that upstream data flows at 33.6 kbps. The upstream data (data sent from the modem) is however sent as analog data.
Unless you update your drivers regularly you may face hardware performance issues.
To check your drivers you should manually verify every device on your system for driver updates
For maximum functionalities, all the user needs to do is connect the Digicom Win Modem PCI V.90 CTR21 to an internet service provider or an organizational site that uses V.90 technology on their networks and telephones lines that works on digital circuits. Like in many v.90 modems, the Digicom Win Modem PCI V.90 CTR21 employs a bidirectional channel, which serves both the downstream and upstream data transfers. The receiving channel (downstream) is able to accept data at higher speeds because no data is lost during the conversion of digital data to analog. On the other hand, the analog to digital conversion that happens during sending (upstream) limits the corresponding data transfer speeds. On purchase, the user is usually provided with the device drivers, which include the data, voice and Fax software, drivers for Windows 98SE, 2000, XP and ME and the user guide. It is highly recommended you run a free registry scan for and Digicom Win Modem PCI V.90 CTR21 errors before installing any driver updates.
