ARGUS

A
RGUS 125
PRI
termination
Depending on the transmission technique (75 Ohm coaxial-cable
or twisted-pair cable with an impedance of 120
Ohms) used, the
PRI termination resistor must be selected accordingly.
The default setting is country-specific and corresponds to the
system most common in the respective country:
Germany, Austria, England, the Netherlands, France, ... :
120 Ohm
Spain, Italy, Greece, ... 75 Ohm
PRI Monitor Select: Monitoring the D-channel or monitoring Layer 1
In the case of the V5 option (selection from three time slots), this
setting is not available.
PRI haul mode The ARGUS supports the setting of the haul mode (sensitivity) of
the PRI access.
By default, “short haul” will be suggested.
short haul:
long haul:
Normal sensitivity, i.e. signal reception with
cable attenuation of up to ca. -10dB.
Increased sensitivity, i.e. signal reception
with cable attenuation of up to ca. -35dB.
This corresponds to a distance of 1600m
with 22AWG twisted pair cable.
When using greater sensitivity (“long haul” mode) on longer lines,
feedback on the line can cause faulty synchronization.
Sa5 bits
settings
The ARGUS can set the Sa5 bits on a PRI access. By default, the
Sa5 bits are set to 0000.
The Sa5 bits have no significance between an NTPM and
a PBX system.
This setting will not be saved permanently, rather only applies for
the current measurement.

settings
The ARGUS can set the Sa6 bits on a PRI access.
By default, they are set to 0000.
