Operation Manual

ARGUS

A
RGUS 125
Telephone connections
Can a telephone call be placed from this access to every other number and/or can this
access receive a call?
Service tests
Does the tested access support connections with the most important services, such as,
ISDN telephone service, Group 4 - Facsimile or data transmission at 64 kbit/s etc.?
Additionally, three user-specific services can be saved in the ARGUS and tested on the
access under test.
Bit error tests (BERT) for PRI/E1, BRI, U-interface accesses with evaluation in
accordance with G.821 and G.826
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 integrated MegaBERT extends the bit error test on E1/PRI accesses to a full 2 Mbit/s
bandwidth. Any distribution of time slots ( n x 64 kBit/s ) may be used.
Supplementary Services
The ARGUS automatically tests the supplementary services made available by the
exchange.
Leased Line Tests – tests permanent circuits with BERT and speech
NT simulation of a BRI- or a PRI access
D-channel monitoring on the Basic and Primary Rate Interfaces
All of the D-channel signals are captured and passed to the serial interface. When
passively monitoring, the ARGUS does not affect Layer 1.
CF Interrogation
The ARGUS will check, whether a call diversion has been setup on the access under test.
The ARGUS can setup or clear down call diversions in the exchange.
MSN interrogation (only on a BRI access)
On a P-MP access using the DSS1 protocol, the ARGUS will determine the MSNs of the
access under test.
POTS (analog) Functionality
Tests CLIP and other Caller-ID services in accordance with ETS 300 659/778.
Monitoring an analog line (passive listening-in)
