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
