White Paper Abstract:
This paper summarizes that the Cisco® IP RAN Optimization solution introduces IP to the RAN network that has traditionally been TDM. Cellular providers have been using TDM based networks to backhaul the traffic from the cell site to the Mobile Telephone Switching Office (MTSO) since deploying their networks for the first time. GSM Abis and UMTS Iub deal with the TDM backhaul in different ways so we have different congestion management solutions for each one. We must address them separately.
