SYSTEM OPERATIONS
(3) Service Conditions (when performing Traffic Measurement via TCP/IP)
(a) The NDM (network-level) data for the traffic measurement order is replaced/updated, at each time
the system is initialized or data change is requested from the ATRFN command.
(b) When the network-level data is once assigned via the ATRFN command, the node-level data for
ATRF command cannot be changed or modified.
(c) When the network-level data is once assigned via the ATRFN command, the already assigned data
by the ATRF command is not cleared, but becomes ineffective.
(d) When a data transfer error occurs, the following are performed in order:
Traffic measurement is suspended momentarily and system message is displayed (notification
of fault)
Traffic measurement, concerning all the remaining data except for the fault-involved one, is re-
sumed
Retry is made repeatedly for the transfer of fault-involved data, until the fault has been eradicat-
ed
If the fault hasn’t been eradicated still until the time of next measurement routine, the data is
finally discarded, and next traffic measurement routine starts
(e) When the same Individual ATT Numbers exist on the network, the traffic measurement concerning
the ATTCON/DESKCON cannot be performed correctly.
