Several alarm panels are Outfitted with a backup communication route to be used when the principal PSTN circuit is not working. The redundant dialer might be connected to a 2nd conversation path, or even a specialised encoded cellular phone, radio, or internet interface device to bypass the PSTN fully, to thwart intentional tampering with the phone line(s).
