ARGUS 152
In the CF test, the ARGUS attempts to set up a call diversion to the call number
that is in the speed-dialling memory location for “remote call number 1” (see
"Saving call numbers in the Speed-dialling Memory" on page 24). When
performing a CF test, the ARGUS will report an error if this location does not
contain a valid call number to which it is possible to divert a call.
CW
Does the access under test support call waiting?
CCBS /
CCBS-T
Will the access under test automatically recall a remote subscriber if the
number called was busy?
CCNR /
CCNR-T
Will the access under test automatically recall a remote subscriber if the call
was not answered?
MCID
Does the access tested allow identification of malicious callers (call tracing)?
3pty
Does the access under test support a three-party conference call?
For this test, you need the assistance of a remote subscriber, whose call
number must be entered. A connection is necessary.
ECT
Is an explicit call transfer supported by the access under test?
For this test, you need the assistance of a remote subscriber, whose call
number must be entered. A connection is necessary.
CUG
The ARGUS then uses a self call to check whether the access under test
belongs to a closed user group.
CD
An incoming call will be diverted immediately. This form of call diversion differs
from the others in that it is invoked on a call-by-call basis, and is not
preconfigured to a specific destination.
AOC
The ARGUS checks whether the charges can be sent to the access under test.
The test uses a call to oneself to check both AOC-D (AOC during a call) and
AOC-E (AOC at the end of a call).
SUB
A call is made to oneself and answered to check the transfer of the sub-
address in both directions.
Are sub-addresses supported on the access under test?
UUS
Does the access under test support the transfer of user data?
No
Screening
If the caller supports CLIP No Screening (CNS) and the ARGUS is in TE mode,
the ARGUS will display all of the connected network-side call numbers. It is
also possible to check the CLIP No Screening function by monitoring with the
WINanalyse software on a PC.
