Performance Monitoring
Once the NCC 2020 is installed, the performance monitoring
routines allow you to monitor the performance of the T1 circuit.
The NCC 2020 maintains a history of the T1 circuit performance for
the previous 24 hours and offers the ability to examine various
tables.
Performance statistics may be viewed in a Craft interface session.
As described by the various technical publications which define ESF
(Extended SuperFrame), the NCC 2020 maintains performance
records in 15-minute intervals. After an NCC 2020 has been
operating for 24 hours, there will be 96 of these 15-minute
intervals stored in the CSU registers.
Performance Monitoring Menu
Most of the information accessible under the Performance
Monitoring Menu is only available with an ESF T1. CRC-6 error
checking, used to detect errored seconds, is only present on an ESF
T1.
The Performance Monitoring Menu is accessed by typing “P” while
at the NCC 2020 Main Menu.
