Information about all recognized TETRA packets are shown as values and graphs to give a quick overview. Global traffic can be shown in the traffic graph to see the share of TETRA traffic on the overall traffic. Measures of packets and data (accumulated and as per second rate) provide an impression of the used capacity. Request-response times show the time difference between request packets and their corresponding response packets. Problems in the packet sequence are available as counters for lost packets (expected sequence number missing), repeated packets (sequence number seen multiple times) and reordered packets (sequence numbers not in expected order). For call packets, the maximum packet jitter is shown. | Information about all recognized TETRA packets are shown as values and graphs to give a quick overview.

All connections with their source and destination IPs and ports are shown. Besides general packet counts, specific packet type counts can be selected for call- and keep-alive-packets. For both types request packets, acknowledged and not acknowledged/erroneous packets are accounted separately. Connection problems can be identified using counters for lost, repeated or reordered packets and by evaluating packet response times. To assess call quality, the maximum jitter of call packets is shown. | All connections with their source and destination IPs and ports are shown.
