ISDN-telefoonverlengkabel ShiverPeaks 70235-6/6 – modulaire RJ-stekker, 15 m

Modular ISDN telephone extension cable ShiverPeaks 70235-6/6 — modular RJ connector, 15 m provides a straightforward wired connection to extend ISDN handsets, terminals or desk phones. The cable uses standard modular RJ connectors with the common pinout for voice and ISDN signalling, offering 15 metres of length to reposition devices or tidy cable runs in offices and homes. It is intended for voice and ISDN connections where a reliable, low-maintenance physical link is required.

Advantages

The extension cable preserves standard RJ pinout to ensure compatibility with most ISDN telephone sets and related equipment. Its 15 m length allows flexible placement of phones without the need for additional adapters or complex rewiring. The modular RJ connectors make installation quick and reversible, and the single-purpose design reduces the risk of signal interference compared with improvised or multi-connector solutions.

How to use

Disconnect the telephone handset or terminal from the existing wall jack or base unit, then plug one end of the modular extension cable into the device and the other end into the wall outlet or base unit following the standard RJ connector orientation. Ensure connectors are fully seated to avoid loose contacts. Test the handset for dial tone and ISDN signalling after installation. For relocation, route the cable along skirting boards or behind furniture to minimize trip hazards and prevent pinching.
