6.1. Module 2x internal line (order No 1880030)
The internal line interface works with a line voltage of 24V and line current of
approximately 30 mA. It is symmetrical, which guarantees good resilience against
line cross-talk. The nominal impedance is 600
Ω
. The module allows caller
identification (Caller ID – CLIP). This module supports the receipt of identification
using DTMF between the first and second ring.
