4.1.1 TE Simulation of a Primary Rate Interface
In the Access mode menu (see page 16), select the desired simulation mode:
-
TE P-P (point-to-point)
Afterwards, the access and the protocol stack will be initialized in accordance with
the selected setting.
4.1.2 NT Simulation of a Primary Rate Interface
In the Access mode menu (see page 16), select the desired simulation mode:
-
NT P-P (point-to-point)
Afterwards, the access and the protocol stack will be initialized in accordance
with the selected setting.
4.2 Initialization Phase including B-Channel Test
Initialization on a PRI network
As soon as Layer 1 is setup, the "L1 Sync" LED will light continuously. The ARGUS will
automatically determine and display, whether or not the PRI access uses CRC4-
monitoring. CRC4 monitoring can be switched on or off manually.
The ARGUS will begin to automatically determine the access configuration. After Layer 2 is
setup, the "L2" LED will also light.
The ARGUS will, regardless of the mode of operation (TE or NT mode), determine the D-
channel protocol and attempt to setup Layer 3.
ARGUS PRI
4 Operation on a PRI Access
During this phase, the ARGUS displays
the A bit of the remote side and the FAS.
The protocol can only be determined
when the A bit is not set (+).
The FAS (Frame Alignment Signal)
indicates whether the ARGUS could
correctly synchronize with the incoming
2 Mbit data stream's alternating frame
identification word or message word and
the, perhaps present, CRC4-superframe
structure.
