INTRODUCTION

The MX2800 provides backup measures of protection for circuit failure. The following subsections
describe the possible modes of operation:
•

Nonredundant Mode

• Circuit Failure Recovery Mode
failure
• Circuit and Network Failure Recovery Mode
and network protection.
The descriptions given include illustrations and suggested configuration settings.
The settings may need modification based on your network configuration.
2. NONREDUNDANT MODE
In Nonredundant Mode, the MX2800 houses only one controller card. There is no failure protection. In the
