Presa ISDN ShiverPeaks 74230-4 — 2 x 8/8, 4 connessioni parallele

The ShiverPeaks ISDN Connection Box 74230-4 provides a compact solution for integrating ISDN lines into small office or telecommunication setups. It offers two 8/8 channel interfaces and four parallel ports to connect multiple devices and distribute digital ISDN services reliably. The unit is intended for surface-mounted installation and enables channel-based routing and parallel device access for PBX extensions, telephone systems and networked communication equipment that require ISDN connectivity.

Advantages

This ISDN connection box supports two independent 8/8 ISDN channels and four parallel ports, enabling multiple devices to share lines without complex rewiring. Its surface-mounted design simplifies installation in existing infrastructure and minimizes required space. The device is built to provide stable digital signal distribution and straightforward channel routing for small-scale telephony and data applications.

Suitable for

• Small office PBX extension and telephone system integration
• Connecting multiple ISDN handsets or terminal adapters in parallel
• Telecommunication setups requiring channel-based routing
• Installation sites where surface-mounted hardware is preferred

Key specifications

• ISDN interfaces: two independent 8/8 channel lines
• Parallel ports: four parallel device connections for shared access
• Mounting type: surface-mounted installation
• Function: channel-based routing and parallel distribution of ISDN signals
• Intended use: integration with PBX, telephone systems and networked communication devices

How to use

Mount the connection box on a suitable flat surface following local wiring regulations. Connect incoming ISDN lines to the designated 8/8 interfaces and attach terminals or devices to the four parallel ports to enable shared access. Configure any connected PBX or terminal adapters to recognize the channel assignments and verify signal continuity and numbering as required. Perform tests on each channel to ensure correct routing and functionality before placing systems into regular operation.

Recommendations

Use certified ISDN cabling and compliant connectors, and follow applicable national telecommunication standards during installation. For multi-device setups, label ports and channels to simplify maintenance and troubleshooting. If integrating with a PBX or complex telephone system, consult the system documentation to map channel assignments and avoid call routing conflicts.
