B-ISDN + ATM

CS: Convergence Sublayer

SAR: Segmentation and Reassembly

PMD: Physical Medium Dependent

TC:Transmission Convergence

Generate packets

larger than a cell

Interfaces to cable. Different

hardware is required for diff.

cables and fibres.

Transmitting end - streams

of bits to PMD. Receiving

end - streams of bits from

PMD to cell stream.

to applications

Segments packets, transmits

cells and reassembles them at

other end
