6. Diagnostics and tests
6.1. Diagnostics
In the top of the screen we find the type of interface, the speed, and clock mode.
The status of the fibre link, the time since the power up, and the main information about the active configuration.
The FO shows an error statistics picture displayed in duration of error or number of errors.
Figures are provided for the last 24 hours, the previous hour and 15 minutes, and the current hour and 15 minutes, which show how the errors
are distributed over time.
The time without fibre carrier, without the DTE carrier.
6.2. Test
6.2.1. Local Analog Loop
The FO synchronizes to the carrier that it transmits on its line interface. This configuration provides a test of all the internal parts in the unit. This
loop corresponds to an ITU-T V54 B3 loop.
Procedure:
This loop is activated

In the third menu of the VT100 interface,

By the AT&T1 command
The loop is acknowledged by the TEST Led on the front panel.
6.2.2. Remote Digital Loop
The remote FO (B) sends back data received from the line which lets the terminal equipment (DTE A) test the data link up to the remote
terminal point (DTE B). This loop corresponds to an ITU-T V54-B2 loop.
Procedure:
From location A, if the answer it RDL request is enabled on the FO of side B

In the menu 3 of the VT100 interface,

By the AT &T2 command
From location B

In the menu 3 of the VT100 interface,

By the AT&T3 command.
