Corporate Dial-up Subscriber ISDN (CDS-ISDN) is an Internet connectivity service that provides unlimited ISDN Internet access per month. This service helps a customer to keep their monthly connectivity budget within its allocated allowance. Moreover, it provides a dedicated modem number (modem pool) with guaranteed user/modem ration of 1:1, to make sure that all subscribers can always connect to the service without sharing the line with other users. This is a huge benefit over general subscriber services.

CDS-ISDN allows maximum connection duration of up to 24 hours per session. To increase convenience in user account management, we provide a web-based service where subscribers can manage user accounts on their own. We also provide Web and Mail services (BizWeb and BizMail) which include e-mail accounts, user account, e-mail space and website space, to support a company's expansion plans.

ISDN (Integrated Service Digital Network) is a system of digital phone connections that allow voice and data to be transmitted simultaneously using end-to-end digital connectivity. 1 ISDN line has 2 channels of data transmission with a speed of 64Kbps per channel (up to 128 Kbps with 2 channels). This makes downloading large files or multimedia files an easy and convenient task.
