Question: What is the primary purpose of a CTS-MS's Access Rights Key in relation to a CTS-FP's broadcasted Fixed Part Beacon Identity (FPBI)?
Option 1: To control access, verifying if the CTS-MS is allowed to connect to the broadcasting CTS-FP based on the FPBI.
Option 2: To encrypt communication between the CTS-MS and CTS-FP for secure data transfer.
Option 3: To identify the CTS-MS for billing purposes on the accessed CTS-FP.
Option 4: To determine the quality of service (QoS) the CTS-MS should receive from the CTS-FP.
Explanation: The primary purpose of a CTS-MS's Access Rights Key is to verify if it can access a CTS-FP by matching its key with the broadcasted FPBI, thus controlling access. This ensures only authorized CTS-MS devices can connect to a particular CTS-FP, enhancing security and access management within the Cordless Telephony System.
