Chart 2. The typical ARC traffic breakdown
Teldat recommends that the network infrastructure in the alarms reception center
is sized bearing in mind the values in the above table.
Through a linear interpolation, we can obtain the bandwidth capacity estimation for a keep-alive of 90
seconds (minimum poll time interval for UL-listed mIP/IPDACT’s):
umber of
mIP/IPDACT
Incoming traffic in the
VisorALARM
Outgoing traffic from the
VisorALARM
500 67 Kbps 61 Kbps
100 106 Kbps 100 Kbps
1500 144 Kbps 139 Kbps
2000 189 Kbps 183 Kbps
2500 233 Kbps 228 Kbps
3000 278 Kbps 272 Kbps
Chart 3. ARC throughput with a poll time of 90 seconds.
If the user wants to adjust the keep-alive timer to receive a Communication loss trouble within 5 minutes,
the keep-alive time interval should be set to 140 seconds, which yields the following estimation:
umber of
mIP/IPDACT
Incoming traffic in the
VisorALARM
Outgoing traffic from the
VisorALARM
500 21 Kbps 19 Kbps
100 32 Kbps 31 Kbps
1500 45 Kbps 43 Kbps
2000 59 Kbps 57 Kbps
2500 72 Kbps 71 Kbps
3000 86 Kbps 84 Kbps
