Datacom ISDN adapter STP 1 to 4 RJ45 ports

Datacom ISDN Adapter STP CAT5E 1:4 RJ45

The passive ISDN adapter Datacom 1:4 is designed for duplicating (parallel forwarding) the signal from one RJ45 input connector (8 pins) to four RJ45 output ports (also 8 pins). All outputs are connected in parallel – the wires 1 to 8 from the input are transmitted 1:1 to all four outputs. The adapter is not an active network element and does not perform a switch function – the outputs cannot be used simultaneously. It is intended for digital ISDN applications, such as signal distribution from NT/NTBA devices to multiple sockets. The shielded design STP provides better interference resistance and is also suitable for more demanding environments.

Features:

• Type: Passive ISDN splitter 1:4
• Connections: 1× RJ45 input, 4× RJ45 output
• Wiring: 1:1 (Wires 1–8 are connected to all ports)
• Category: CAT5E
• Shielding: STP (Screened Twisted Pair)
• Usage: ISDN devices, NTBA, telephone systems

Note: This is not an active element (switch) – the outputs are connected in parallel and cannot be used simultaneously.
