InLine ISDN Port Doubler 1x RJ45 male / 2x RJ45 female with Cable 69932A

The InLine ISDN Port Doubler connects a single RJ45 ISDN line to two RJ45 female ports, allowing two devices to share one ISDN connection. The adapter is supplied with a short cable (0.15 m) and has a compact grey housing suitable for use in office or home network setups.

Advantages

The compact in-line adapter requires no additional power and provides a simple physical solution to split an ISDN RJ45 connection into two female ports. Its pinout is designed to map the RS- and TS-pairs appropriately between the male and each female connector, preserving required signal pairs for typical ISDN devices.

How to use

Connect the RJ45 male plug to the ISDN wall socket or upstream ISDN source. Plug ISDN devices into the two RJ45 female ports. Verify device compatibility and configure call or line settings on the connected equipment as required by your service provider. The adapter is passive and does not provide electrical isolation or signal amplification.

Recommendations

The adapter is intended for splitting the physical RJ45 ISDN connection for short-term or low-complexity setups; for permanent multi-device installations or where simultaneous independent ISDN lines are required, use a proper ISDN splitter/hardware compliant with your provider's specifications or consult a network technician.
