EasyLine GSM 2G PSTN telephone line simulator for alarm control panels

PSTN telephone line simulator on GSM network

EasyLine GSM is an analog line simulator designed to connect an alarm control panel or telephone dialer to the GSM mobile network. Via the TIP/RING terminals, it provides the control panel with a simulated line, allowing it to send alerts or voice messages via calls.

Main functions

• Simulation of the analog telephone line via TIP/RING connection.
• Support for Contact ID and 4/2 protocols.
• One input for SMS reporting and one open collector output.
• Output control via call with caller identification and numbers stored on the SIM.
• Programming via SMS with security code or via telephone with DTMF tones.
• GSM antenna with SMA connector included.

Remote input and control

The input is normally closed (NC) by default and can send a notification to the configured number when the contact opens. The open collector output can be controlled by calling numbers stored on the SIM card: the original card indicates a capacity of 250 or 500 numbers, depending on the SIM.

Applications

It can be used to connect devices designed for analog telephone lines, such as alarm control panels and dialers, to the mobile network. Compatibility with the connected device, the monitoring center, and the available network must be verified before installation.

Mobile network: This version uses 2G GSM; requires coverage and a SIM card enabled for the necessary services on the 2G network.
