Voice network module Auerswald COMpact 4FXS Modul

The Auerswald COMpact 4FXS Modul is a compact voice network module that adds four FXS ports to supported Auerswald communication systems. With a slim housing measuring 160 mm × 25 mm × 70 mm, the module provides analog interfaces for connecting standard analog telephones, fax machines and other analog devices to a digital telephony system. Designed for clean integration with compatible Auerswald boards and enclosures, the unit extends voice connectivity while preserving a small footprint.

Advantages

The module supplies four independent FXS interfaces in a compact form factor, enabling straightforward expansion of analog endpoints without requiring large additional hardware. Its modest dimensions make installation into system chassis or racks easy where space is limited. The device supports standard analog signalling and ring generation for telephones and fax equipment, ensuring compatibility with a wide range of legacy analog devices. The design focuses on functional integration with Auerswald systems to maintain consistent operation and management.

Suitable for

• Small and medium office telephony systems requiring analog extensions
• Home offices that need to connect analog phones or fax machines to a central system
• Service and repair environments where legacy analog devices must be retained
• Installations where compact modules are preferred to save rack or chassis space

How to use

Install the COMpact 4FXS Modul into a compatible Auerswald system slot following the system’s installation instructions. Connect analog telephones or fax machines to the FXS ports using standard telephone cables. After physical installation, configure the module and port settings through the host system’s administration interface to assign extensions, configure ringing and tone parameters, and enable any required call features. Verify operation by testing calls, ring behaviour and fax transmission as applicable.

Usage recommendations

Place the module in an environment with adequate ventilation and avoid exposure to moisture or excessive dust. Use short, quality telephone cables for reliable signal quality and follow the host system guidelines when assigning port parameters. For installations with multiple analog devices, plan numbering and ringing profiles to avoid conflicts and ensure predictable behaviour for users.
