Notice to Telco: Meets FCC Class C
Ringing current: 105-Vrms sinusoidal ringing superimposed on
-48 VDC; a ring generator must be installed in the power supply module
of each carrier that has an 008 OPT module.
REN:
≤ ≤ 1.0 per port
Disconnect signal: 900 ms (T/R short for answering machines,
G3 fax, etc.)
Switchhook flash detection: 300-1200 ms
Loop resistance: Serves 2-wire loops to 1300 ohms, including stations
■
The system recognizes the OPT module as an 012 module having 12 ports.
However, the OPT module has only 8 jacks. Therefore, each installed OPT
module decreases the system’s capacity by 4 ports.
