- Switching Node (switchboard)

Telephony at the Turn of the Century

Manual Operators

Already Characteristic Architecture

- Adaptation of Mode of Information Transfer (MIT)in one network to MIT in another which provides a

service to the first.

- Topology of transmission links (copper)

- Adapted Data sources (telephone)

Evolution of Connectivity Management

Network Management = Army of Operators Limitation to further expansion

Almon B. Strowger invents step by step mechanism and automation begins

Evolution of Connectivity Management

DDF provides manual Topology Configuration

Transmission multiplexing gives rise to clear

Client and Server Layers

Each Layer has all the Qualities of Network

- Point to Point Connectivity

- Topology etc.

Digital Revolution

Digital Communication introduced forinteroffice applications.

Emerging International Standard of 64 Kbit/s

and 8 KHz Sampling Rate.

Main driving force technological not market.

Operations exclusively manually connectedby DDF.

Support by paper and manual recordkeeping.
