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
