Operation Manual

ARGUS
A
RGUS 125 25
Initialization phase:
- Intialization on a BRI or U-Interface access
Next the ARGUS will setup Layer 1. While it is setting up Layer 1, the “L1 Sync” LED above
the display will blink. If the ARGUS cannot setup Layer 1, it will display the message “No
Net”. When the ARGUS is operated on a U-interface access, it can take up to 2.5 minutes
to activate Layer 1. As soon as Layer 1 is successfully setup, “L1 Sync” LED will light
continuously.
Once Layer 2 has been setup, the “L2 Rx/Tx” LED will light.
If both modes (P-P / P-MP) are found when Layer 2 on the D-channel is checked,
the mode must be selected manually (see page 33).
If everything has been correctly detected, the ARGUS will display the type and mode of
access found. Additionally, a qualitative assessment of the level will be displayed.
The ARGUS will automatically determine the protocol (in both TE and NT mode) or use the
protocol set manually (see page 120 Protocol). On a bilingual access, the ARGUS will use
the DSS1 protocol.
The “L3 Conn” LED will light after the ARGUS has setup Layer 3. At the same time the
ARGUS will start the B-channel test. The results will be displayed on the ARGUS. If an
error occurs in the B-channel test (e.g. access is not plugged-in), the ARGUS will -
depending on the class of error - either repeat the initialization or show an error message
(see page 145). The ARGUS will then idle in the Status display.
