TSA identification media and access control media are the property of TSA. 165321 Media Access Control This sublayer which depends on a physical layer is a procedure controlled by the sender in which several devices on multidrop or bus networks compete to gain access to the medium for data transfer.

BD AC must not only enforce access control policies on data leaving the MS it must also control access to the CSs resources. And advance proposals of particular relevance to the Commissions Media Ownership priorities and rulemaking including. In some systems complete access is granted after s successful authentication of the user but most systems require more sophisticated and complex control.
