10.8 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 ten 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)
- MSN with national area code without the leading “0”
- MSN with country code without the leading “00”
- complete call number
In order to interrogate the MSNs, the access under test must support the
supplementary service “Call Forwarding (CF)”.

In this example, the ARGUS displays the first MSN
(2351919658) of a total of three found (1/03).
Use the cursor keys to scroll through the results.
Due to differences in the protocol, some exchanges do not support MSN
interrogation. In this case, the ARGUS will report: MSN interrogation not possible!
