## Summary description

helos ISDN extension cable model 018120 is a 6 m cable with an RJ‑45 male connector to a 6‑position female socket designed to extend ISDN connections. It preserves signal routing for compatible ISDN equipment, enables flexible placement of terminals or network devices, and simplifies installation where original cabling is out of reach.

## Long description

helos ISDN extension cable 018120 is a 6 m extension lead with an RJ-45 male plug and a 6‑position female socket designed to extend ISDN terminal connections. The cable maintains the original signal routing required by compatible ISDN devices and provides additional reach for terminals, NT/TA devices or wall outlets when fixed cabling is out of reach. The straightforward wiring preserves line integrity and enables simple, temporary or semi-permanent extension without re-terminating installed wiring.
Advantages
The helos ISDN extension cable offers six metres of flexible reach while keeping the pin configuration required for standard ISDN connections. Its male RJ-45 connector mates with standard ISDN modem or terminal sockets and the 6‑position female socket accepts existing ISDN plugs, so no changes to device settings are normally required. The cable construction reduces handling effort during installation and allows quick repositioning of devices. Because it simply extends the existing line, it supports troubleshooting and temporary setups without altering wall wiring.
Suitable for
 Extending ISDN terminal connections to reach telephones, terminals or NT/TA devices
 Temporary relocation of ISDN devices for testing or maintenance
 Connecting devices where wall outlet or fixed cable is inaccessible
 Laboratory or installation environments needing a reliable ISDN extension
Key specifications
 Connector A: RJ-45 male (wired for ISDN pinout)
 Connector B: 6‑position female ISDN socket
 Cable length: 6 metres
 Cable type: shielded/unshielded twisted pair as used for ISDN wiring (manufacturer standard)
 Color and jacket material: manufacturer standard PVC jacket suitable for indoor use
 Compatibility: designed for ISDN S/T or terminal interfaces that accept standard 6‑position plugs via an RJ-45 to 6P adapter wiring
How to use
Plug the RJ-45 male connector into the ISDN-compatible RJ-45 socket of your terminal, NT/TA device or adapter. Insert the ISDN plug from your device into the 6‑position female socket at the cable’s other end. Ensure connectors are fully seated to maintain correct contact and signal routing. Route the cable to avoid sharp bends, kinks or exposure to high heat and secure it with cable clips or ties if a longer-term installation is needed. If connection issues occur, check that both ends are seated and that the connected devices are powered and configured for ISDN operation.
Usage recommendations
Use this extension for indoor ISDN setups and temporary relocations; avoid outdoor exposure or prolonged mechanical stress. For permanent installations or when electromagnetic interference is a concern, choose appropriate shielding and routing practices and verify compatibility with your ISDN equipment before extended use.
