Appendix B Configuration Examples Overview 270642 UMTS Only Configuration without IMA The traditional UMTS configuration is similar to the GSM configuration except only UMTS traffic traverses the topology. Unlike GSM traffic, UMTS traffic arrives at the RAN-O device via ATM PVCs. The UMTS traffic is then routed over the traditional MLPPP backhaul connection. At the RNC side, the RAN-O to RNC connectivity is exactly like the Node-B to RAN-O interface connections. Aside from the necessity of ATM connectivity, the physical connectivity for UMTS is exactly like the GSM topology (see Figure B-9 on page B-59).
