Pay-Per-Use ISDN (PPU ISDN) is perfect for an organization currently using 56 Kbps, but who wants to upgrade to High-Speed Internet. It is also a good choice for a new ISDN user who prefers flexibility of use and does not want to be bound by a fixed monthly expense due to a limited budget. With PPU ISDN, you can specify the number of usage hours according to your needs.

PPU ISDN can also be utilized as an emergency back-up link for an organization currently using another type of Internet connectivity.

A major advantage of PPU ISDN is that customers can login for as long as 24 hours per session without being disconnected from the service. For added convenience in user account management, we also provide a web-based service where subscribers can manage their accounts on their own. Other Web and Mail services that can support the expansion of your organization include e-mail accounts, Internet accounts, mailboxes and web hosting. These services, bundled as BizWeb and BizMail, can be chosen if appropriate for your company.
