Telephone Communication Module SATEL GSM-X-PSTN for GSM-X module — PSTN interface

SATEL GSM-X-PSTN is a telephone communication module intended to expand the SATEL GSM‑X module with a PSTN (analog telephone) interface. The module provides a landline connection option for alarm control panels and security installations that require both GSM-based communication and an analog telephone channel. It allows integration of a standard PSTN line as a fallback voice/telephony path and enables external dialing through the analog network when connected to the GSM-X core.

Advantages

The GSM-X-PSTN module adds an analog line interface to the GSM-X system without altering the primary GSM functions. It supports voice and signaling via PSTN, ensuring an alternative communication channel if GSM service is temporarily unavailable. The design is compact and intended for straightforward installation alongside an existing alarm panel, enabling reliable PSTN connectivity for monitoring centers and on-site telephony access.

Suitable for

• Alarm control panels requiring both GSM and analog telephone connections
• Security installations needing a fallback voice channel over PSTN
• Sites where external dialing via a landline is required for maintenance or notifications
• Systems integrating monitoring center communication via analog PSTN

Key specifications

• Interface type: PSTN (analog telephone) for integration with GSM-X module
• Functionality: voice path and telephony dialing via analog landline
• Compatibility: designed to work with SATEL GSM-X core module in alarm systems
• Installation: module intended for mounting within alarm equipment enclosures
• Application: fallback communication channel and external PSTN access for security systems

How to use

Install the GSM-X-PSTN module in the alarm system enclosure and connect it to the SATEL GSM‑X module following the manufacturer’s wiring diagrams. Connect the analog telephone line to the module’s PSTN input to enable the landline path. Configure the GSM-X module settings to enable PSTN fallback and define dialing behavior for the analog channel. After installation, verify line presence, voice quality and signaling with the monitoring center or test calls.

Usage recommendations

Use the PSTN interface as a complementary channel to GSM communication, and test the fallback operation periodically. Ensure the analog line is from a reliable provider and keep wiring inside the alarm enclosure tidy and secure to prevent interference with other system components.
