ARGUS PRI 5
1 Introduction
When fully equipped, the ARGUS supports a comprehensive range of test functions for not
only BRI accesses and POTS, but also for U-interface, E1/PRI, ADSL, VDSL, SHDSL and
Ethernet accesses. This manual covers the optional E1/PRI interface.
In addition to TE/NT simulation on a PRI interface, the ARGUS also supports D-channel
monitoring on PRI accesses.
Furthermore, it supports tests of digital leased lines including bit error rate tests (BERT) in
the D-channel. The MegaBERT expands the bandwidth to 2 Mbit/s - to either 2048 kbit/s
(framed) or 1984 kbit/s in time slots 1-31 (2 Mbit unframed). Last but not least, the ARGUS
can run a BERT to a remote loopbox or perform an end-to-end measurement to another
ARGUS.

PRI Functions
- Bit Error Rate Test (BERT) for E1/PRI in accordance with ITU-T G.821
Performs a BERT in an extended call to itself, via a loopbox or in end-to-end
operation. The ARGUS will, if needed, handle the loopbox function itself.
The optional MegaBERT extends the bit error test on E1/PRI accesses to a full 2
Mbit/s bandwidth.
- Leased Line Tests – tests permanent circuits with BERT and speech
- NT Simulation of a Primary Rate Interface
- D-channel monitoring on the Primary Rate Interface
All of the D-channel signals are captured and passed to the USB interface. When
passively monitoring, the ARGUS does not affect Layer 1.
- Test of Layer 1

3 Connection for a PRI network
Since there is no commonly accepted standard for the connections in the 2 Mbit sector, you
will be confronted with different forms of connectors depending on the type of terminal and
the network termination used.
The ARGUS changes the connector pin assignments automatically in accordance with the
mode, TE or NT. Additionally, it is also possible to change the pin assignments manually in
the L1-Status menu.

In the Access mode menu (see page 16), select the desired simulation mode:
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.
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.
- TE P-P (point-to-point)
Afterwards, the access and the protocol stack will be initialized in accordance with
the selected setting.
- NT P-P (point-to-point)
Afterwards, the access and the protocol stack will be initialized in accordance
with the selected setting.
4 Operation on a PRI Access
18 ARGUS PRI
Press the <Start> softkey to have the ARGUS begin to test the availability of all 30 B-
channels one after the other by occupie the B-channels.. If the ARGUS can place a call on
a B-channel, it will be assumed that the B-channel is available in both directions; the B-
channel test cannot distinguish between alternating and exclusively "outgoing" B-channels.
If the connection is rejected, the B-channel will be identified as unavailable. In the case of a
cause, which indicates that the B-channel is occupied, the connection will be tried up to two
times and, if a connection can still not be setup, it will then be marked as unavailable.
The ARGUS will display the following:
- Type of access
- Access Mode
- Bus configuration
- D-channel protocol
- The availability of the B-channels
Available B-channels: green circle
is indicated by three rows
of red or green circles.
B-channel 1 is at the upper left
B-channel 30 is at the lower right
In the example, all 30 B-channels are
available and can be used for outgoing or
alternating connections.
- CRC4-monitoring, A-Bit, FAS
B-channel test – example:
The ARGUS is in TE-Simulation Slave
mode.
B-channel 2 and 23 are not available or
are busy. This state is indicated in the
display by the red circles. Green circles are
used to indicate the available B-channels.
If the ARGUS is not properly connected
(e.g. incorrect cabling) or the network is
not in order, the ARGUS will display “No
Net”.

4.3 Configuring the PRI Parameters
The following PRI parameters can be configured as needed. The procedure for configuring
a parameter will be illustrated with a single example: It is possible to restore the default
settings for the parameters (see the ARGUS main Manual).
The ARGUS - Main menu
Use the cursor keys to select, e.g.
Protocol.
Mark the desired protocol. The
selected protocol will be marked in
blue (in this example, Automatic).
The default protocol will be marked
in the display by a . The ARGUS
will use the default protocol for the
PRI connection.
Open the next higher menu without
making any changes. The ARGUS
will continue to use the default
setting.
The ARGUS will use the marked
setting as the default and return
to the next higher menu.

Setting Explanation
Protocol Instead of allowing the ARGUS to automatically determine the
protocol (setting: Automatic), it is also possible to manually set the
Layer-3 D-channel protocol. The ARGUS will save the protocol
setting permanently, i.e. it will use this protocol the next time that it
is switched on.
Default setting: Automatic
Alerting mode You can specify whether, for an incoming call on a PRI point-to-
point access, the ARGUS should display only the access number
without extension or the complete number with extension.
If it is set to “Manual”, the ARGUS will display the extension (an
incoming call will be signaled. The ARGUS will send the Layer 3
message “Alert” when it accepts the call. The digits of the extension
that have been sent by this point will be displayed.).
With the Manual setting, an incoming call must be
answered within 20 seconds or it will be lost. Furthermore,
you should note that the remote subscriber will not hear a
ringing tone.
If it is set to “Automatically”, the ARGUS will only display
the access number without extension or, depending on the
configuration of the access in the exchange, it may not
display the number called at all.
Default setting: Automatic
Clock mode This parameter sets where the clock will be generated in the case
of a BRI or PRI access. You can either specify that the ARGUS
generates the clock (is Master) or that it is the slave of a clock
generated at the other end (Slave).
Default setting:
NT mode
TE mode
Leased line
Master
Slave
Slave
This setting will not be saved permanently, rather only applies for
the current measurement.
