The Auerswald COMpact 2a/b module is an expansion module for the COMpact 3000 series, including variants analog, ISDN and VoIP. It serves to extend the telephone system by two additional analog extensions, thereby increasing the number of available analog endpoints. The module is designed as a plug-in module and is inserted into an expansion port of the system. It enables the connection of two analog telephones or other analog endpoints to the system.

Applications
This module is specifically designed for use in existing COMpact 3000 systems, regardless of whether they are based on analog, ISDN or VoIP technology. It is suitable for companies requiring an extension of analog subscriber capacity without having to change the existing system architecture. Integration takes place without additional hardware or software modifications to the system itself.

Functions and equipment in detail
The module supports the display of the calling number (CLIP) and the name of the calling subscriber (CNIP), provided these details are supplied by the network. These functions are useful for identifying incoming calls, especially in office environments with multiple employees. The connection of analog endpoints is made via symmetrical lines, ensuring stable signal transmission. The connections are designed for use with IWV and MFV technology, ensuring compatibility with various analog telephones.

Technology explained simply
The range of analog subscribers is approximately 790 meters with a line attenuation of 50 Ohm and a cable diameter of 0.6 mm. This means that endpoints can be connected over a considerable distance from the system, as long as line quality and attenuation remain within the specified limits. The symmetrical connection technology reduces interference and improves signal quality, especially over longer connections. Support for CLIP and CNIP provides better visibility of incoming calls, as caller information is displayed directly on the telephone.

Compatibility and accessories
The module is exclusively designed for the COMpact 3000 series by Auerswald and can only be used in systems of this series. It is usable regardless of the system's technology (analog, ISDN, VoIP). Compatibility with analog endpoints is ensured, provided they support the standards for IWV and MFV connections.

Installation and mounting
Installation is carried out by inserting the module into a free expansion port of the COMpact 3000 system. It is a plug-in module requiring no additional tools or settings. The system automatically detects the module, and the new analog extensions are available immediately after installation. End device cabling is done via the integrated connections on the module.

Advantages in operation
Extending the system by two analog extensions increases the flexibility of the telephone system. Support for CLIP and CNIP improves communication efficiency, as callers can be quickly identified. The symmetrical connection technology and high range ensure reliable signal transmission, even over long lines. The module is compact and can be integrated into existing systems without additional configuration.
