15.3.1. Switched Mains Outputs
The 3 off IEC connectors provide the switched mains outputs. Each output is rated at
1A and is individually fused. A neon indicator shows when the output is live. The
outputs are driven by zero cross-point drivers. When an output is activated, the A.C.
voltage level at that output will be equal to the mains input voltage used to power the
unit.
15.3.2. Telephone Connections
The telephone connections are wired pin to pin from Line to Handset except when the
Ring Mute control input is asserted. In this case the ring signal to the Handset is
muted. The status of the telephone Line is continually monitored so that Handset
ringing and off-hook conditions can be indicated.
15.3.3. Remote External Control Inputs
The 15 way D-type connector provides the control inputs that switch the three mains
outputs and control the telephone handset ring mute. All inputs have both active high
(+5V to +30V) and active low (0V) control. An output-on or “Tally” indication for each
output is also provided on this connector in the form of three open-collector driven
outputs capable of sinking 20mA each. The connections are as follows:
Pin 1: Remote 1 (Active High)
Pin 2: Remote 1 (Active Low)
Pin 3: Remote 2 (Active High)
Pin 4: Remote 2 (Active Low)
Pin 5: Remote 3 (Active High)
Pin 6: Remote 3 (Active Low)
Pin 7: Ring Mute (Active High)
Pin 8: Ring Mute (Active Low)
Pin 9: Output 1 Tally (Open Collector)
Pin 10: Output 2 Tally (Open Collector)
Pin 11: Output 3 Tally (Open Collector)
Pin 12: No Connection
Pin 13: No Connection
Pin 14: 0V
