Specifications
Capacity: 8 T/R stations* on 2-way voice transmission path
with support for telephones with message-waiting LEDs;
2 TTRs
Notice to Telco: Meets FCC Class C
Ringing current: 105-Vrms, 30-Hz sinusoidal ringing
superimposed on -48 VDC; a ring generator must be installed
in the power supply module of each carrier that has a
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
Capacity: 12 T/R stations on 2-way voice transmission path
with support for telephones with message-waiting LEDs, 2
TTRs
Power: 21-VDC, 600-ohm battery source
Ringing current: 105-Vrms, 30-Hz sinusoidal ringing
superimposed on -48 VDC; a ring generator must be installed
in the power supply module of each carrier that has a 012
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
* 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.
