Monitoring the DSU/CSU 6

What to Monitor

This chapter presents information on how to access and monitor DSU/CSU status

and performance statistics on the T1 network. You can monitor DSU/CSU

operations by monitoring:

LEDs on the Status screen or the DSU/CSU’s front panel

System and Test Status screens

Highest priority Health and Status message on the last line of all screens

Cross Connect Status screen

Network Interface Status screen

Network Performance Statistics screen

Network Management System via SNMP MIB objects

SNMP traps and other information reported by your NMS via SNMP MIB

objects
