NEC NDA-24300 manual System Operations

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 theATRFN 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.
