Airbridge cBTS3612 CDMA Base Station
This chapter firstly presents an outline of the cBTS3612 base station system, and
then briefs the system features, technical indices and external interfaces, followed
by an introduction to the system reliability design in aspects of hardware and
software.

1.1 Brief Introduction

The cdma2000 1X mobile communication system comprises the Base Station
Subsystem (BSS) and the Core Network (CN). The BSS comprises the Base
Transceiver Station (BTS), Base Station Controller (BSC) and Packet Control
Function (PCF), while the CN comprises the packet domain network and circuit
domain network. The equipment of packet domain interworks with Internet, and that
of the circuit domain interworks with the conventional PLMN and PSTN/ISDN. The
system's operation and maintenance is implemented via the integrated mobile
network management system (iManager M2000).
