Question: When utilizing PVCs (Permanent Virtual Connections) over an ATM transport network for IP packet transmission on the UTRAN Iu interface, which LLC encapsulation option is mandated for both O&M and ATM Inverse ARP association methods?
Option 1: Multiprotocol Encapsulation over AAL5
Option 2: Classical IP and ARP over ATM only
Option 3: Generic Flow Control (GFC) with AAL2
Option 4: Service-Specific Connection-Oriented Protocol (SSCOP)
Explanation: According to the specified telecom standards for UTRAN Iu interface data transport, when Permanent Virtual Connections (PVCs) are utilized over an ATM transport network, the "Multiprotocol Encapsulation over AAL5" option is required for LLC encapsulation. This applies uniformly across association methods, including both Operations and Maintenance (O&M) configurations and those employing ATM Inverse ARP, ensuring consistent IP packet transmission protocols. This standardization facilitates efficient and reliable data transport across the network.
