Ethernet and ISDN sharing with the correct T-adapter

10/100Base-T + ISDNCat 5e15 cm

EFB-Elektronik K5123.015 is the Cat 5e cable-sharing T-adapter for a 10/100Base-T and ISDN service combination. One RJ45 male plug connects to two RJ45 female sockets through a 15 cm lead. Its wiring differs from a two-Ethernet-output splitter, so match the exact model and diagram to the installation.

RJ45 connection format

Frequently Asked Questions

Is it interchangeable with K5122.015?
No. K5122.015 is the two-10/100Base-T model; K5123.015 is the Ethernet/ISDN variant. Their intended services and wiring differ.
Does it convert ISDN into Ethernet?
It is a cable-sharing wiring adapter, not a protocol converter or an active network switch. Both services require the appropriate equipment and matching end-to-end cabling.
Singular Expert Insight
Specify the two required services before choosing a T-adapter. Identical RJ45 housings can hide different pin assignments, so the model number and wiring diagram matter more than appearance. Confirm your Ethernet and ISDN cable-sharing arrangement
