INTRODUCTION

DTM is a form of circuit switching for fiber-optic networks

DTM employs TDM (time division multiplexing).

DTM channels are simplex to achieve high bandwidth.

The DTM architecture was conceived in 1985 and developed at the Royal Institute of Technology in Sweden

WHAT IS DTM ?

DTM is a broadband network

architecture .

DTM is based on circuit switching

augmented with dynamic

reallocation of time slots.

BASICS OF DTM

PRINCIPLE OF DTM

Basic technologies :

Circuit Switching

Time Division multiplexing (TDM)

Channel Establishment

CIRCUIT SWITCHING

Network resources are reserved all the way from sender to receiver before the start of the transfer

Control signalling and payload data transfers are separated

Traditional voice telephone service is an example of circuit switching.

TIME DIVISION MULTIPLEXING

Signals are operate in same

frequency in different time slot.

It’s a base band transmission.

In synchronous TDM time slot are pre assigned.

DTM multiplexing format

DTM CHANNELS

Channels in DTM have the following properties

Simplex

Multirate

Multicast

Renegotiated

ADVANTAGE

Increases the use of fiber's transmission

capacity.

Provides support for real-time broadband traffic & multicasting.

Dynamically allocates the distribution of

resources to the network nodes

APPLICATION

Real-time traffic & multicasting required in videos

Transmission of integrated data, both audio & video.

Enterprise Access and Private Data Networking

CONCLUSION

DTM aims to reduce network complexity

DTM provides full access to available bandwidth.

DTM provides a guaranteed quality of service (QoS) for streaming

video services.
