1. This sublayer deals with the access requests to the channels. 2. The Physical logical-sublayer contains a physical coding sublayer ( PCS ). 3. The Physical logical-sublayer contains a physical coding sublayer ( PCS ). 4. This sublayer allowed to avoid medium absorbing the paint. 5. For these protocol stacks only the multiplexing capabilities of the LLC sublayer are used. 6. There is a new sublayer called Channel Access and Control sublayer ( CAC ). 7. There is a new sublayer called Channel Access and Control sublayer ( CAC ). 8. The Data Link Layer is subdivided to include a media access control ( MAC ) sublayer . 9. Higher-layer protocol overhead ( above the media access control sublayer ) is normally neglected. 10. However, most protocol stacks running atop 802.2 do not use LLC sublayer flow control and error management.
