Integrated telecommunication system architecture for wireless and wireline access featuring PACS radio technology

In a communication system having a plurality of terminals configured to exchange user communication signals, a device for routing said user communication signals among said terminals comprising:

• a backplane bus having a number of modular connection means;
• a controller device connected to said backplane bus through at least one of said modular connection means;
• a plurality of interface devices connected to said backplane bus, each through at least one of said number of modular connection means, said interface devices being configured to provide said user communication signals through said backplane bus in a format and at a rate determined by said controller device;
• wherein said format comprises a time division format in which said user communication signals are divided among a plurality of frames, each frame having a predetermined number of time slots, a first number of said time slots providing system control data and a second number of said time slots providing user data corresponding to said user communication signals.
