Front 1

Match the five basic levels or classes of network service provided by the transport layer are :
Class 0 - 5
Class , basic error recovery class: used where signaled error rate is unacceptable.

Class , error detection and recovery class: Class 3 with residual error discovery/correction. Used where residual error rate is unacceptable.

Class , multiplexing class: Class 0 with transport connection multiplexing.

Class , error detection and recovery class: Class 1 with multiplexing.

Class , simple class: Basic transport connection used where both error type rates are acceptable.

Back 1

Class 0, simple class: Basic transport connection used where both error type rates are acceptable.

Class 1, basic error recovery class: used where signaled error rate is unacceptable.

Class 2, multiplexing class: Class 0 with transport connection multiplexing.

Class 3, error detection and recovery class: Class 1 with multiplexing.

Class 4, error detection and recovery class: Class 3 with residual error discovery/correction. Used where residual error rate is unacceptable.
