DO-RNC Functional Overview
1xEV-DO Base Station Controller Communicate and Control
multiple DOM(s)
Uses IP-Abis interface (Standard GRE encapsulation)
Communicate with PDSN over R-P interface (A10/A11)
Support Automatic Failure Recovery DOM(s) dynamicly homed to
Redundant DO-RNC if primary one failed (A13)
Comprehensive Redundancy Features IP Load Balancing, Hot-swappable Power supplies/fans/modules, Warm-Standby System
Controller.
Cost-effective operations and management via EMS and existing
Operational Support Systems (OSSs) Standards compliant IS-856/1xEV-DO, 3rd Generation Partnership
Project 2 (3GPP2) Wireless IP Network Standard

DO-RNC Modules
BIO -
Supports two 100 Base-T Ethernet ports. Supports TCP/IP stack over the Ethernet connections to both PDSN and Backhaul Network. Supports Abis Link connection(s) toward DOM(s)
Supports for installation in multiple slots in DO-RNC IP Load Balancing for increasedBandwidth and Redundancy.
RNSM -
Responsible for terminating the signaling and session setup components of the 1xEV-DOprotocol.
Serves multiple DOM(s) and automatically balances the traffic load with other RNSM(s)installed within the same DO-RNC system
Supports for installation in multiple slots in DO-RNC increases the number of DOM(s)served, and cost-effectively scale as cell site coverage area and capacity grows
SC -
Responsible for System Configuration, Routing Protocols, Disk operation, NetworkManagement, and 1xEV-DO Signaling/Session setup activities
Communicate with the RNSM and BIO modules over backplane connection
Supports 1+1 System Redundancy ( both in Slot-7 & Slot-9 )

RNC Disk Operation Overview
Slot_7 SC card is mapped todisk1: ( in green)
Slot_9 SC card is mapped to
disk2: ( in blue ) Active disk is always
designated as disk0: whichis a virtual disk and canactually be either disk.
In Redundant modeoperation, SC writes to
disk0: which goes to bothphysical disks as part ofautomatic DiskSynchronization.

CLI (Command Line Interface)
Can be accessed via console port at the back
of SC module
Each BIO module also has an operational
console port
All Console ports are 38.4 Kbps baud rate. Support most Terminal Emulation
Most CLI configuration will be on SCmodule
