Technical Requirements

Operation of NRT requires a dedicated analogue telephone line reserved exclusively.
The following connection types are supported:

• Analogue telephone line

• Analogue extension of an PABX

• Telegärtner IP gateway

The connection point (TAE socket) should ideally be installed in the machine room or close to the terminal point of the travelling cable.
Two free cores within the travelling cable are required for the telephone line. To reliably avoid interference, use twisted and shielded pair cables.

In addition, a power supply of 12–24 V DC / 600 mA must be available.

Scope of Delivery

Intended Use
