Patch panel slim wirewin PANEL TEL 25 — 25‑port ISDN, 1U, light gray

The slim wirewin PANEL TEL 25 is a 1U rack-mount patch panel that provides 25 ISDN ports in a compact, light-gray chassis. It is intended for telephony distribution and ISDN line termination in network racks, allowing centralised organisation of subscriber or trunk connections in small to medium installations. The panel's slim 1HE profile saves rack space while maintaining standard rack compatibility and clear port labelling for straightforward cable management.

Advantages

This 25-port ISDN patch panel offers dense port capacity in a single rack unit, reducing rack space usage compared with bulkier solutions. The light-gray finish and standard 19-inch mounting make it compatible with common rack systems. Centralised termination simplifies cabling, reduces installation time, and makes maintenance or moves easier by keeping ISDN lines accessible and logically arranged.

Suitable for

• Small to medium-size PBX or telephony rooms requiring ISDN line distribution
• Network cabinets where rack space is limited and a 1U solution is preferred
• Installations needing centralized subscriber or trunk terminations for easier maintenance
• Environments where compatibility with standard 19-inch racks is required

When it may not be suitable

This panel is designed specifically for ISDN ports and telephony termination; it is not suitable as a general-purpose Ethernet patch panel for RJ45 networking unless adapters or different wiring are used. For installations requiring more than 25 ISDN ports or integrated data and voice management in a single device, a larger or mixed-panel solution may be more appropriate.

Key specifications

• Port count: 25 ISDN ports
• Form factor: 1U (1HE) rack-mount
• Finish: light gray
• Mounting: standard 19-inch rack compatible
• Application: telephony / ISDN line termination and distribution

How to use

Mount the panel into a standard 19-inch rack occupying one rack unit. Terminate ISDN subscriber or trunk cables to the panel ports following your site wiring scheme and telephone equipment documentation. Label each port clearly to match central exchange or PBX assignments to simplify identification. Use appropriate cable management and strain relief to maintain neat routing and reduce mechanical stress on terminations. Routine checks of connections and labels will help ensure reliable operation.

What to consider before purchase

• Confirm that your installation requires ISDN-specific ports rather than RJ45 Ethernet connections
• Verify that 25 ports meet current and planned capacity requirements
• Ensure compatibility with standard 19-inch rack mounting and available 1U space
• Plan for cable management and labeling to maintain accessible terminations

Usage recommendations

For best results, combine the panel with clear port labelling and organised cable runs. Regularly verify terminations after installation and keep spare port documentation to speed troubleshooting and future expansions.
