Integrating Axon IPTV with the PAGA System

What is a PAGA System?

A Public Address General Alarm (PAGA) system integrates broadcasting with emergency communication and alarms, enabling a fast, safe and efficient communication with the offshore personnel.

We always request for the PAGA documentation from the client, then we evaluate how to do the integration with the IPTV system. Below is the short description how our integration is made.

How our side toward PAGA works

You have one or more SNMP agents which track and report alarm status conditions. Typically, one SNMP agent is assigned to a sector. Each SNMP agent has an IP address and tracks multiple alarms. Each alarm is assigned an OID (a SNMP variable). OIDs must be unique for every distinct alarm within an agent, but they may overlap between agents.

The agent must fulfil two additional requirements: it has to send SNMP traps if an alarm condition changes, and it has to allow the values of OIDs to be read (the values represent the state of the alarm, e.g. 1 => alarm is signalled, 0 => all is good).

On the server side, you provide a list of agent IP addresses and the OIDs which need to be tracked for every agent. You also define all alarms (in multiple languages) and map them to OIDs and their values. The server initially traverses though all the agents and reads all OIDs to determine the initial state. Then it keeps listening for any incoming SNMP traps and updates the state accordingly.

The server can act as a standalone SNMP manager (your SNMP agents send traps directly to our server), or alternatively, you need to configure your SNMP Manager to proxy the traps to our server.

When the alarm status changes, the client devices (STBs) are notified. You can configure which device parameters are changed according to the global alarm state (e.g. mute audio). The alarm text is also displayed on the screen.
