ADDITIONAL TELCO OUTPUT clienfeed / N-1 logic
OUT-2 (ANALOG-OUT-2) source could be configured as 2 different TELCO mono outputs:
TELCO 2: ANALOG-OUT-2-L
TELCO 3: ANALOG-OUT-2-R
to use the 2 above signals as 2 separate telco output lines please set the related parameter as follow:
MAIN / AUDIO / OUTPUTS / ANALOG / OUT-2 / source
N-1 T2/T3: TELCO 2 caller and TELCO 3 caller can hear each other.
N-1 T2+T3: TELCO 2 caller and TELCO 3 caller can not hear each other.
DANTE-OUT-1 could be configured as 2 different TELCO mono outputs:
TELCO 4: DANTE-OUT-1-L
TELCO 5: DANTE-OUT-1-R
to use the 2 above signals as 2 separate telco output lines please set the related parameter as follow:
MAIN/AUDIO/OUTPUTS/DIGITAL/DANTE-1/ source
N-1 T4/T5: TELCO 4 caller and TELCO 5 caller can hear each other.
N-1 T4+T5: TELCO 4 caller and TELCO 5 caller can not hear each other.
USABLE GPIO FOR THE ADDITIONAL TELCO LINES
If the GPIO port is not already used, it is possible to implement a GPIO communication with all of the
additional external TELCO devices by using the GPIO port.
The SUB-D9 pin-out is described in the GPIO PINOUT scheme, resumed by the picture below:
In this previous scheme is described the pinout of this SUB D9 connector.
Each GPI and each GPO is manageable from the menu.
