Introduction

With Cisco IOS Release 12.4(16)MR and later, Cisco 3825 series integrated services routers can be used in an Internet Protocol Radio Access Network (IP RAN) environment. The Cisco IP RAN feature provides both:

Global System for Mobile Communication (GSM) Abis Optimization over IP and

Universal Mobile Telecommunication System (UMTS) Iub Optimization over IP

The Cisco IP RAN feature enables bandwidth efficient transport of GSM and UMTS traffic between the Base Transceiver Station (BTS) and the Base Station Controller (BSC) in GSM RANs and between Node B and Radio Network Controllers (RNC) in UMTS RANs. This results in significant reductions in operating expenditures to the mobile wireless operator and enables new revenue-generating services for the future.

System Configuration Requirements

When being implemented in an IP RAN solution, the Cisco 3825 series integrated services router requires the following minimum software installation:

Cisco IOS Release 12.4(16)MR1 software

Memory Recommendations
