The E1 ‑ 2 Mb/s display consists of the main display window, the left status display window, and the upper status display window.

The Left Status Display Window shows the status of E1 ‑ 2 Mb/s key parameters, including the Test Mode, Line Code, TxClock, Receive Input, Framing Mode, Error Type, Pattern, Payload Type, Impedance, and Measurement Status.

The bottom main menu keys control the submenu keys on the right. Five active main menu keys are provided: Configuration, Pattern, Error/Alarm, Measurements, Start/Stop.

The Upper Status Display Window shows status of the Receive (Rx), Transmit (Tx), and Alarm/Error parameters. The Rx shows the history and current status of the Signal, Frame Alignment Signal (FAS), and the Pattern Sync. For Rx, the parameters are Signal, FAS, and Pattern Sync. For 2 Mbits, the parameters are Alarms and Errors. For TX, the parameters are Alarm ON and Error ON. The first column shows the history (H), and the second column shows the current status. A red indicator signifies an error, and a green indicator signifies no error. The history can be cleared by pressing Measurements and then Clear History.
