Similarly you may ssh the PR1 Appliance thru the new ppp0 interface.
PPP OVER SERIAL PC
TX packets:6 errors:0 dropped:0 overruns:0 carrier:0Īnd we may ping PR1 Appliance from the PC (or vice versa) like ~]# ping 10.0.0.209 RX packets:6 errors:0 dropped:0 overruns:0 frame:0

PPP OVER SERIAL SERIAL
On the host we may have configuration like this:įinally let's load the ppp over serial link modprobe ppp_async
The PR1 Appliance console has no flow control signals wired (RTS,CTS, DTR, DSR, etc.) so we say nocrtscts. PR1 Appliance will get address 10.0.0.209 and the other end will be 10.0.0.2. PR1 Appliance will use /dev/ttyBF0 device for the PPP. On the PR1 Appliance set the PPP configuration file Please enable it and build the image.Ĭonnect the serial port of a PC with PPP support with the PR1 Appliance console port.Įstablish the ssh sessian with the PR1 Appliance. In the latest Switchfin we have PPP option in the menuconfig. PPP is a data link layer protocol mainly intended to establish point to point connection over the serial link like the console port we have on our Switchfin targets.

Supporting Contact ID protocol is available in Asterisk mainstream since Asterisk 1.2) Here we go we have AlarmSender() Asterisk application implemented in Switchfin. It uses based on a sequence of DTMF tones with handshake and a control sum incorporated. And the protocol is Contact ID invented by a company calledĪdemco which become de-facto a standard for this kind of alarm panel central station communication. Have been widely used in the past and even now. Thanking into account the old infrastructure heritage it is not a surprise that the POTS analog telephone lines
So the question is what is the best communication media and protocol used for this. The best practice is to collect all the 'alarm events' from all alarm panels in a single central station. Those premises are often spread in a very different geographical locations within a town or even country. In a typical alarm system scenario there are numerous alarm panels spread in a different armed premises.

As you may know Switchfin GUI can be configured in English, French, Russion, Portuguese
