ABOUT THIS DOCUMENT
PURPOSE
Over the past several years, basic digital signal level 1 (DS1) service has evolved to include new
capabilities and thereby support more sophisticated applications. The three prime applications are:
1.
2.
3.Digital multiplexed interface with bit-oriented signaling (DMI-BOS)
Digital multiplexed interface with message-oriented signaling (DMI-MOS)
Integrated Services Digital Network primary rate interface (ISDN-PRI)
Since these three applications merely build on each proceeding...

xxviABOUT THIS DOCUMENT 

INTRODUCTION1-3
ISDN is a collection of international recommendations that are evolving toward adoption as a CCITT
telecommunications standard. These recommendations are based on the following objectives:
1.To provide the user with end-to-end digital connectivity (which in theory will be independent of
the network provider)
2.To use the end-to-end digital connections as shared (integrated) facilities, thus permitting the same
channel to be used alternately for voice, data, or imagery/video
3.
To permit...

1-4INTRODUCTION
The BRI terminates at a subscriber’s residence or office. There, it connects either to an ISDN
compatible terminal or to a conventional terminal via a terminal adapter. The BRI channel structure
consists of a 2B + 1D format. Each B or bearer channel provides a 64K-bps information channel. Each
D-channel provides a 16K-bps signaling channel.
NOTE: Specific descriptions for BRI layers 1, 2, and 3 are not included here. Another document
that fully describes ISDN-BRI architecture, specific...
