MANAGEMENT SYSTEM CHARACTERISTICS

7.1.

General

The powerful integrated supervisory system of Evolution Series provides user-access to the NEs in a most
dynamic manner. The management function in the NE can be accessed by the use of a web-browser,
Command Line Interface (CLI) or by a SNMP manager such as the NERAs management systems
NetMaster EM/NMS.
Note 1: Configuration from CLI is limited.
A NE is controlling all the units connected to a specific node with a common supervisory unit. The NE
software performs the following management tasks:
Fault management:
Performance management:
Configuration management: Configuration of node (including configuration up/download) and
Security management:
7.1.1.

Event logging

Evolution Series NEs can log events and faults in the local fault log. The log size is 10.000 events. The
log can be set to wrap-around or halt when it is full. Alarm logging can be masked based on severity
level. An operator (with administrator privileges) can also clear the log.
7.1.2.

Monitoring of system performance

Transmission performance data is monitored continuously by the built-in supervision function. The
supervision function performs measurements and calculations based on the parity bits in each E1/T1.
Traffic bit error rate information from the modem is also available.
