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).
