A box in your rack watches every OLT, switch and router you run. HansaNet tells you what is really down and since when, and does not page you for a blip or for every ONU under a dead OLT.
What runs where
The probe is one small program on a machine in your rack. On Windows it installs from one setup .exe and starts at boot. On Linux it is a .deb. It only ever dials out, so nothing on your network has to be opened up for it.
Everything else sits with HansaNet: the outage record, the pages, the dashboard and the history. The probe updates itself, and a bad update rolls back on its own.
What counts as down
A real outage is confirmed in about a minute. A single missed ping opens nothing and pages nobody. When the device answers again the outage closes, and the restored message says how long it was down.
One page for the root, not a storm
You enter what feeds what: the core router feeds the OLT, the OLT feeds its PONs and the switches behind it. A dead OLT is one outage and one page. Everything below it is shown as unreachable and pages nobody. Time a device spent unreachable because its parent was down is left out of its own uptime.
When the drops look like an area power cut, the outage carries that note for your team. The note never changes who is paged.
The watchdog and live ping
HansaNet also watches the probe. If the probe stops reporting you are told, once, and told again when it comes back.
For a technician standing at a device, live ping puts the results on the screen, one line per packet, so a run of losses looks different from scattered ones. A session stops on its own. Workers can open it, on the phone too. Watching a device pages nobody and changes nothing in its record.
What it does not do
- It does not work out the cause. Whoever resolves an outage types that in, and the outage will not close without it.
- It does not page on optical power, PON calls, ONU state or latency. Those are recorded and shown on screen. See optical monitoring.
- It does not watch a subscriber's own router. A router that goes dark while its ONU is up pages nobody. Router tools live under TR-069.
- A second feed you record for redundancy is not taken into account yet.
- The probe accepts nothing from outside. If your setup needs to reach into it, this is the wrong tool.
What the page says and who gets it is on WhatsApp alerts for staff. The uptime figures built from these outages are on uptime reports.
