The PC should now be set up for alarm receiving.

Using PPP as a backup to Network Alarms

For the purpose of this tutorial, the Unit is connected between the network and a serial TA (or

modem). The TA is connected to an ISDN line or PSTN Modem.

The receiving PC is networked and has NetVu ObserVer running with the Event Distribution Point

Software, and is also connected to and ISDN or PSTN Modem.

The site has the unit is networked to an ADSL router, which is set up as the primary connection. If

this connection is disabled, the unit will use the secondary connection, the serial ISDN TA (Terminal

Adapter).

At the ARC, there is a PC running the Event Distribution Point software and two other PC’s running

NetVu ObserVer. These all share a Cat5 network with an ADSL router and ISDN router. The ADSL

router would be the normal network entry point for alarms over the internet, whereas the ISDN

router, connected to the ISDN wall socket, would be the entry point for PPP alarms.

The unit will be congured to dial up over ADSL to send alarms to the receiving centre, but also

using PPP over the ISDN line if this primary connection is down. The EDP will then distribute the

alarm to any available ObserVer on the network. This tutorial, combined with the previous one,

should give a good overview of the technology involved.
