ISDN adapter DATACOM 4260 — 1 to 4 RJ45 ports

DATACOM 4260 ISDN adapter converts a single ISDN interface into four RJ45 ports, allowing multiple ISDN-compatible devices or terminal adapters to be connected to one line. The compact 10 cm black adapter preserves existing ISDN wiring while expanding connectivity for telephony equipment, fax machines and legacy network devices that require ISDN access.

Advantages

The adapter offers a simple passive conversion from one ISDN interface to four RJ45 ports using standard RJ45 pin assignments for each connector. Its short 10 cm length and black housing make it easy to place near existing equipment without additional cabling. No power supply or configuration is required, enabling immediate use with compatible ISDN devices.

Suitable for

• Small office or home ISDN setups with multiple terminals
• Connecting several ISDN telephones or terminal adapters to one ISDN line
• Legacy fax machines or network devices requiring ISDN interface
• Temporary or permanent expansion of existing ISDN wiring

How to use

Connect the RJ45 male plug to the ISDN line or ISDN socket on your wall or central unit. Plug ISDN-compatible devices into any of the four RJ45 female sockets. No additional configuration or power source is required; the adapter provides a passive connection that shares the single ISDN interface among connected devices. Verify device settings and line compatibility before connecting multiple active ISDN terminals simultaneously.

Usage recommendations

Use the adapter in environments with clearly compatible ISDN equipment and avoid connecting multiple active ISDN devices that expect a dedicated line without checking for possible conflicts. For professional or complex ISDN installations, consult a technician to ensure correct line termination and signal integrity.
