IS128

DESCRIPTION

ISDN (Integrated Service Digital Network) is the most convenient and economical way to use the existing copper wire for both voice and data communication. ISDN, with its digitized technology, provides high quality service for voice conversation and data transmission such as file transfer  Internet access.

With the new ITU-T I.430 2B+D worldwide standard, bulk data transmission has been up rated to 128K. The ISDN not only provides 128K transmission but also allows voice conversation and fast Internet Access simltaneously. The new BOD (Bandwidth On Demand) function allows the user to utilize the bandwidth in a more flexible fashion. Upon request, it can release one B-Channel for user to make an incoming or outgoing call while both B-Channels are occupied by data application (ML-PPP). Upon finishing the voice call, it will recover the bandwidth to 128K.

Supplementary services, such as call waiting, call transfer, call forwarding, three-party conference, call filtering, calling number display etc. are also supported. The ISDN can also be used as  leased line backup for Inter-Networking solution. Compared with the traditional leased line, ISDN is more economical and flexible. Therefore, the it can be expanded not only for the end and SOHO (Small Office Home Office) users but also for more and more operation in the future.
