The ports labeled "Network Clock," "10BaseT," "Dial Shelf
Interconnect," "Console," and "Alarms" are safety extra­low voltage
(SELV) circuits. SELV circuits should only be connected to other SELV
circuits. Because the E1/T1 circuits are treated like telephone­network
voltage, avoid connecting the SELV circuit to the telephone network
voltage (TNV) circuits.
