Overview
The Radio Access Network-Optimization (RAN-O) supports a variety of topology designs based on various Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS) configurations. Here are some common pieces to this topology:
•
A backhaul interface is used to transfer optimized GSM/UMTS traffic between RAN-O devices. The traditional backhaul interface is comprised of one or more T1/E1 controllers logically combined to form a multilink connect (except High-Speed Down link Packet Access [HSDPA] which uses the backhaul interface for T1/E1 line clocking). The current versions of RAN-O deployment will include faster backhaul interfaces such as Fast Ethernet (FE) and Gigabit Ethernet (GE).
•
A shorthaul interface is used to transfer GSM and UMTS traffic from the Base Transceiver Station (BTS)/Node-B to the Cisco 3825 router and from the Cisco 3825 router to the Base Station Controller/Radio Network Controller (BSC/RNC). The traditional shorthaul connections on the RAN-O devices are connected through the Cisco 2-port T1/E1-RAN interface cards.
•
Topology naming conventions such as, 3x2 and 4x3 are used to describe the type of deployment. The first number signifies the number of GSM/UMTS shorthaul interface connections while the second number signifies the number of multilink backhaul interface connections. In the case of a combined GSM/UMTS network, the conventional 3:2x2 can be used where :2 signifies the number of UMTS shorthaul interface connections.
Asymmetric PWE3 Configuration
The following is an example of an Asymmetric PWE3 configuration (see Figure B-1):

GSM Only Configuration
The standard GSM topology includes one or more shorthaul interface connections from the BTS to a RAN-O device via separate T1/E1 connections. The RAN-O devices are connected back-to-back using an MLPPP backhaul connection (two or more T1/E1 connections). At the BSC side, the RAN-O to BSC connectivity is exactly like the BTS to RAN-O connections. In this scenario, only GSM traffic traverses the topology (see Figure B-8).

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).
