CFB:
Can this access forward an incoming call when it is busy; in other
words does it support call forwarding busy?
CFNR:
Can this access forward an incoming call when it is not answered?
In the CF test, the ARGUS attempts to set up a call diversion to the call number
that is in the speed-dialing memory location for “remote call number 1” (see
"Saving call numbers in the Speed-dialing Memory" on page 339). The CF test
cannot be performed, 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.
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.
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?
