## Long description

The VoIP module Auerswald Comtrexx 90025 GbE-NET Module for COMtrexx Flex systems is an expansion board that adds Gigabit Ethernet network connectivity to Auerswald COMtrexx telephony platforms. It is designed to integrate seamlessly with COMtrexx Flex systems to enable SIP-based trunking and IP endpoint registration over a high-throughput Ethernet interface, increasing data capacity and helping maintain consistent call quality in small and medium business environments.
Advantages
This GbE-NET module provides a Gigabit-capable network interface that supports higher data rates than standard Fast Ethernet connections, reducing latency and packet congestion in multi-call scenarios. The module is built to match COMtrexx system requirements for power, signaling and management, allowing centralized administration of VoIP trunks and IP extensions. Its integration improves overall reliability of SIP communications and offloads traffic from slower network interfaces, which can result in clearer audio and fewer dropped calls under load.
Suitable for
 Small and medium enterprise VoIP telephony systems requiring higher network bandwidth
 Installations with multiple SIP trunks or large numbers of IP endpoints
 Office environments seeking to reduce voice packet loss and jitter
 System upgrades where existing COMtrexx units need Gigabit Ethernet capability
Key specifications
 Interface: Gigabit Ethernet network connector for integration with COMtrexx Flex chassis
 Function: Enables SIP trunking and IP endpoint connectivity over Gigabit links
 Supported traffic: Optimized for VoIP RTP/RTCP streams and SIP signaling
 Form factor: Expansion module compatible with COMtrexx Flex system slots
 Operational environment: Designed for business telephony installations with standard office ambient conditions
How to use
Install the GbE-NET module into an available expansion slot of a COMtrexx Flex system following the system's hardware installation instructions. Connect the module's Gigabit Ethernet port to the local network switch or router using a Cat5e or Cat6 cable to ensure full Gigabit performance. Configure SIP trunks and IP endpoints in the COMtrexx management interface, assign network parameters such as IP address or VLAN tagging as required, and verify call routing and codec settings to match your PBX and service provider requirements. After installation, monitor traffic and call quality metrics to confirm the module is handling expected loads.
Usage recommendations
For consistent VoIP performance, connect the GbE-NET module to a Gigabit-capable switch or router and use quality cabling (Cat5e or Cat6). When deploying multiple SIP trunks or many IP devices, enable QoS on network equipment and separate voice traffic using VLANs where possible. Keep COMtrexx system firmware updated and verify codec and jitter buffer settings to optimize audio quality.
