15.2.2 DESCRIPTION
Pins 8 and 9 are used to make RING LED on the Telco module panel blinking when a call is coming in (call signalling
may be also achieved via one or two ‘red light’ lamps connected to the two Power Supply relays – see par. 15.3).
The remote interface photocoupler (pin 9 = Anode and pin 8 = Cathode) must be driven by an external suitable command
generated by external telephone hybrid. Typical current allowed: 5 mA (max 10 mA). Max voltage allowed: 15 V.
A + 15 VDC is provided on Pin 6 via a 470 Ohm resistor.
The Oxygen 5’s Hook optoinsulator closes whenever ‘Hook’ button is pressed. Typical current allowed: max 10 mA. Max
voltage allowed: 15 V.
It may be necessary to consult the hybrid manufacturer’s user manual in order to control its functions.
OXYGEN 5 Telco remote interface has been designed for direct connection to BOXTEL and MACROTEL 5 / 7 / 9 by
Axel Technology.
In particular, a regular, not crossed Pin – to – Pin 9 pole cable featuring standard RS232 connectors (i.e 9 pin serial
connection computer type) is required for BOXTEL connection.
