| Controlled by a programmable timer and a fixed threshold value determining the call data buffer capacity (80 % of the call data buffer is full), the TFTP client (HiPath 3000/5000) sends call data to the TFTP server (external application). If the system cannot set up a connection to the TFTP server, it addresses an alternative server. If this server is also unavailable, it outputs an SNMP trap or error message ("Unable to output data"). The system tries to set up another connection every 60 seconds. A call data buffer overflow causes an error message to be entered in the error history file.
