This is some ethernet cable split and used as low-voltage signal wires.
The current wiring of the gate phone keypad, to the brains in the grey box behind, is:
|#||From cable bundle||To phone component|
|1||Gray wire||row 1, pin D0|
|2||Green wire||row 2, D1|
|3||Brown wire||row 3, D2|
|4||Red wire||row 4, D3|
|5||Orange wire||column 1, D4|
|6||Blue wire||column 2, D5|
|7||Blue + Black dot wire||column 3, D6|
From the phone, there are blue column wires and red row wires.
Added to this, the red LED and front buzzer share a signal wire pair. Green and yellow are used for these. The wp:LED has bias, a correct direction. The buzzer, phone earpiece, is driven directly by the arduino, using a tone generation library. The LED can be setup alone, and lights on each keypress, to confirm good wiring.
The last 2 white wires are reserved for future use supporting voice from the phone.
