To externally inhibit the Transmit carrier, either apply a TTL/CMOS 'low' signal to pin 7, or
short pin 7 to ground (for example with an external relay closure).
All relay contacts are rated 30V DC 2A, or 125VAC 0.4A.
Note: N/O means 'normally open' in the non-fail state of the modem (relays energised)
when power is removed the relays fall back to the non-normal (i.e. non-energised) alarm
state.
