Once the equipment is correctly installed, it may be necessary to monitor the quality of service
before putting live traffic on the circuit, depending on the installation rules of the network.
The AM2048 has various features that help the user to do this with a high degree of
confidence without the use of extra test equipment. A terminal plugged into the ELU gives
access to the following information:
In the “Performance > M.2100” History screen, the display records errored seconds, severely
errored seconds and unavailable seconds for the aggregate line system. The recording interval
and the pass-fail criterion of the datalog record are programmable by the user to match the
tables found in ITU Recommendation M.2100.
In the “Performance > Transmission Line” screen, the display records G.826 statistics for both
ends of each transmission line.
Once the circuit is working, the “Alarm > History” screen should be checked and cleared.
The alarm history should be checked after a suitable interval to ensure that no alarms are
occurring.
(For more details of the menu system see the “VT100 Management User Guide for the
AM2048.”)
