14.1.1 TE Simulation
In the Access mode menu (see page 240), select the desired simulation mode:
14.1.2 NT Simulation of a S-Bus Interface
In the Access mode menu (see page 240), select the desired simulation mode:
14.2 Initialization Phase Including B-Channel Test
Initialization on a S-Bus interface or U interface access
The ARGUS will begin the initialization after according the existing, confirmed settings or
new settings for the type of access and mode:
The ARGUS will first setup Layer 1. While Layer 1 is being setup, the "Sync / L1" 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 "Rx/Tx/L2" LED will light.
-
TE automatic
On a BRI or U-interface access, the ARGUS will automatically determined the D-
channel Layer 2 mode (PP or P-MP). If the ARGUS determines that the access
supports both modes, a configuration menu will open in which you can select the
desired Layer 2 mode.
-
TE P-P (point-to-point) or TE P-MP (point-to-multipoint)
The access and the protocol stack will be initialized in accordance with the
selected setting.
-
NT P-P (point-to-point) or NT P-MP (point-to-multipoint)
The access and the protocol stack will be initialized in accordance with the
selected setting.
