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

Accessing File System

From the Enable prompt:

Nortel-07#shell

File operation executed inside the shellNortel-07(shell)(disk0:/)#

Unix-like commands such as ls to see files,cp to copy etc.

Type exit to return to Enable prompt:

Nortel-07(shell)(disk0:/)# exit

Nortel-07#
