Logic Control in Tesira
Device
Logic I/O
1 logic input per audio channel, up to 16 channels per block (56 ganged)
Operation
Logic input 1 causes audio channel to mute. Logic input 0 causes audio channel to un-mute.
Mute Control
1 logic input for level up (+) on each audio channel. 1 logic input for level down (-) on each audio channel. Level Inc/Dec
Up to 32 audio channels per block (64 ganged)
1 logic input per preset, up to 10 presets per block
Logic 1 input to (+) causes level to ramp up. Logic 1 input to (-) causes level to ramp down. Optional: Disable ramping Transition from logic 0 to 1 on (+) causes audio to increment up. Transition from logic 0 to 1 on (-) causes audio to increment down.
Transition from logic 0 to logic 1 triggers preset to recall
Remote Preset
19 logic inputs and 1 logic output
Transition from logic 0 to logic 1 on input 1 to 16 causes the associated speed dial number to be dialed. Transition from logic 0 to logic 1 on Rdl input causes the last number to be redialed.
TI Dialer
34 logic inputs (17 for each line) VoIP Dialer
BIAMP SYSTEMS TECHNICAL SUPPORT GROUP
Transition from logic 0 to logic 1 on input 1-x to 16x causes the associated speed dial number in the corresponding line to be dialed. Transition from logic 0 to logic 1 on Rdl-x input causes the last number to be redialed in the corresponding line.

1 logic output per input channel, up to 256 channels per block
Logic output normally Logic 0 Switches to Logic 1 as long as corresponding input channel is gated on. Optional: Behavior of logic output may be inverted in control dialog.
Gating Auto Mixer

Room Combiner
1 logic output per partition plus 5 source selection outputs (4 sources + Off) per room, up to 32 rooms (58 partitions) per block
Logic 0 on partition input causes partition to remain open. Logic 1 on partition input causes partition to remain closed Transition from logic 0 to 1 on source inputs selects the corresponding audio source (or Off) for the corresponding room Logic 0 on partition output indicates partition is open Logic 1 on partition output indicates partition is closed Logic 1 on any source selection output indicates that source (or Off) is selected for that room
1 Logic input per channel, up to 32 channels 1 Logic output per channel, up to 32 channels
Transition from logic 0 to 1 on logic inputs selects the corresponding audio source Logic outputs normally logic 0. Logic 1 on logic output indicates corresponding audio source is selected
Source Selection 1 on logic input causes program audio to duck and logic output to be 1. 0 causes program to un-duck. 1 logic input and 1 logic output Ducker

Logic 1 on HS input picks up the line or “takes off hook”. Logic 0 causes the line to hang up or “Put back on hook” Transition from logic 0 to logic 1 on HF input causes a hook flash. Logic 1 on RI = line is ringing Logic 0 on RS = line is not ringing Logic 1 on DIP = Dialing in progress Logic 0 on DIP = Not dialing Logic 1 on HSS = Off hook Logic 0 on HSS = On hook
2 logic inputs and 10 logic outputs
Logic 1 on DTD = Dial tone detected Logic 0 on DTD = No dial tone Logic 1 on BTD = Busy tone detected Logic 0 on BTD = Busy tone not detected
TI Control/Status Logic 1 on RTD = Ring tone detected Logic 0 on RTD = No ring tone detected Logic 1 on LR = Line ready Logic 0 on LR = Line not ready Logic 1 on LIU = Line in use Logic 0 on LIU = Line not in use Logic 1 on LI = Line intrusion Logic 0 on LI = No line intrusion Logic 1 on LF = Line fault detected Logic 0 on LF = No line faults

Transition from 0 to 1 on ANS x.y answers the call on appearance x line y Transition from 0 to 1 on END x.y ends the call on appearance x line y
VoIP Control/Status
24 logic inputs (two per appearance per line) and 26 logic outputs (two per appearance per line plus 2 per line)
Logic 1 on RI x.y indicates appearance x on line y is ringing Logic 1 on LIU x.y indicates appearance x on line y is in use Logic 1 on LR1 (LR2) = Line 1 (2) in line ready mode Logic 0 on LR1 (LR2) = Line 1 (2) in not ready mode
Network Command String
Serial Command String
1 logic input per command string, up to 32 per block
Transition from logic 0 to 1 triggers command string to output network port.
1 logic input per command string, up to 32 per block
Transition from logic 0 to 1 triggers command string to output serial port.
