ARGUS 3u plus/3u NT
9.8 MSN Interrogation (only on a BRI with DSS1)
On a P-MP access using the DSS1 protocol, the ARGUS
will determine the MSNs of the access under test. It will
display a maximum of 10 call numbers. Depending on the
Type of Number (TON), the ARGUS will display the call
numbers in different versions:
• only the MSN (without area code)
• with national area code without leading the “0”
• with country code without leading the “00”
• complete call number
In order to interrogate the MSNs, the access under test must
support the supplementary service “Call Forwarding (CF)”.
In the Single tests menu,
use the < ↓ > to select MSN

interrogation not possible!
