INTRODUCTION

  • ISDN is an acronym, which means Integrated Services Digital Network.

  • It is a set of CCITT / ITU standards for digital transmission over ordinary telephone copper wire as well as over other media.

  • ISDN is the integration of both analogue or voice data, together with digital data over the same network.


N isdn architecture

N-ISDN Channels

B Channel- 64 kbps

D Channel- 16 or 64 kbps

H channel –

H0 = 384 kbps ( 6 B )

H10 = 1472 kbps ( 23 B)

H11 = 1536 kbps ( 24 B)

H12 = 1920 kbps ( 30 B)

Conclusion

ISDN is an underlying technology, which provides cost- effective networking through the public telephone networks.

ISDN is an important step forward in the adaptation of the network to handle the increasing global demand for computer-to computer data communications.

ISDN brings us closer to the goal of a ubiquitous multi-service network, integrating voice, data, video and image.
