[EAS] EAS Digest, Vol 21, Issue 12

[Arthur Leisey]

Mike,

Your concept of having the EAS box decode DTMF is entirely possible.  The manufactuer would need to modify their firmware to handle this.  However, due to the need to have an Internet connection for receiving CAP messages, your remote site inherently has Ethernet available.  At least two major suppliers of EAS gear have been moving to more IP-centric architectures in their deployments, using the Dataprobe CC-IP-CC switch for remote control.  And, at least one even embeds the TX control commands into their firmware.
