Módulo de interfaz ISDN 1xPRI DeTeWe MiVoice Office 470 centralita 1 PRI

ISDN 1xPRI DeTeWe MiVoice Office 470 PBX interface module 1 PRI is an interface module designed to integrate with the DeTeWe MiVoice Office 470 communication system, providing a single ISDN Primary Rate Interface (PRI) trunk connection. The module enables digital trunking for simultaneous voice channels and signalling over a single PRI line, supporting standard ISDN PRI protocols for connection to public networks or central office equipment. It is intended for installation in office PBX environments where scalable digital trunk capacity and reliable signalling are required.

Advantages

The module provides a single, standards-compliant PRI interface that supports multiple simultaneous voice channels and signalling, reducing the need for multiple analog trunks. Its integration with the MiVoice Office 470 system ensures consistent configuration and centralised management of digital trunks. The compact design is suitable for rack or chassis installation within the PBX frame and supports industry-standard ISDN protocols for interoperability with network carriers and central office equipment.

Suitable for

• Medium-sized office telephony systems requiring a single PRI trunk
• Connecting MiVoice Office 470 PBX to public ISDN PRI services or central office links
• Sites that need digital trunking for multiple concurrent voice channels and signalling
• Environments where standard ISDN PRI compatibility is required for interoperability

Key specifications

• Interface type: ISDN Primary Rate Interface (PRI)
• Trunk count: single PRI trunk supporting multiple B-channels
• Supported signalling: ISDN PRI signalling standards (Q.931/PRI-compatible)
• Compatibility: designed for integration with MiVoice Office 470 PBX systems
• Form factor: PBX interface module for installation in the system chassis or card slot

How to use

Install the ISDN 1xPRI module into an available interface slot of the MiVoice Office 470 system following the PBX manufacturer’s hardware installation procedure. After secure mounting and cabling to the PRI line provided by the carrier or central office, configure the trunk parameters in the MiVoice Office 470 administration interface: set the PRI line type, channel allocation, numbering plan and any required signalling parameters. Verify carrier settings such as timing, framing and line coding to ensure interoperability. Perform test calls and signalling checks to confirm correct operation of voice channels and supplementary services.

Recommendations

Ensure that the carrier or central office supports ISDN PRI and provide the correct line profile and channel allocation before installation. Use appropriate surge protection and grounding for the PRI line. Keep PBX firmware and module configuration up to date to maintain compatibility and security.
