Line characteristics
• 0.4 mm cable: approximately 1 km (maximum distance between set and cabinet)
• 0.6 mm cable: approximately 1.8 km (maximum distance between set and cabinet)
The voltage and current measured at the set terminals must be:
• U = 12.4 V / I = 25 mA
All digital sets are protected against most problems caused by human error: short-circuiting,
connection to an analogue extension socket, etc. In such cases, the set will remain silent.
