DTM (Dynamic Synchronous Transfer Mode) is a broadband network architecture based on circuit switching and time division multiplexing. It employs simplex channels and allows for dynamic reallocation of time slots. DTM aims to efficiently use bandwidth on fiber optic networks and provide quality of service for real-time multimedia traffic like video streaming. It has applications in enterprise networks and transmitting integrated audio/video data.

3. 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

4. WHAT IS DTM ?
 DTM is a broadband network
architecture .
 DTM is based on circuit switching
augmented with dynamic
reallocation of time slots.

5. BASICS OF DTM

6. PRINCIPLE OF DTM
 Basic technologies :
 Circuit Switching
 Time Division multiplexing (TDM)
 Channel Establishment

7. 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.

8. 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.

9. DTM multiplexing format

10. DTM CHANNELS
Channels in DTM have the following properties
 Simplex
 Multirate
 Multicast
 Renegotiated

11. 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

12. APPLICATION
 Real-time traffic & multicasting
required in videos
 Transmission of integrated data,
both audio & video.
 Enterprise Access and Private
Data Networking

13. 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.
