Advanced GPIO (Zenitel Connect)

The Advanced GPIO functionality is typically used when Zenitel Connect is integrated with a PAGA system and acoustic feedback occurs because the operator intercom is located close to overhead loudspeakers. In PAGA systems, this is commonly referred to as Local Mute, where loudspeakers in the vicinity of the operator position are temporarily muted during live announcements to prevent acoustic feedback.

To implement Local Mute, one or more GPOs (relay outputs) can be connected to the PAGA system and used to temporarily mute the affected loudspeakers during announcements.

Two common use cases are supported:

1. Operate a relay when a specific broadcast group is active

The relay is activated whenever announcements are made to a designated broadcast group, allowing the corresponding PAGA speakers to be muted.

2. Operate a relay when a specific operator intercom performs a live broadcast

The relay is activated only while announcements are initiated from a designated operator intercom, allowing speakers near that operator position to be muted during live broadcasts. This enables a Local Mute function for the operator location without affecting loudspeakers in other areas.

The "Advanced GPIO" is available as from firmware 1.11.

Operate a Relay When a Specific Broadcast Group Is Active

Navigate to Features > Advanced GPIO.

Select the device that provides the relay output.
Select the required GPO/Relay from the list.
In the GPO Rules pane, click the + icon to create a new rule.
Select the Incoming Broadcast to Group rule type.
From the Directory Number drop-down list, select the broadcast group that should trigger the relay.
Set the desired GPO State:

On - The relay remains activated while the broadcast group is active.
Slow Flash - The relay output flashes at a slow rate while the broadcast group is active.
Fast Flash - The relay output flashes at a fast rate while the broadcast group is active.

When an announcement is made to the selected broadcast group, the configured relay output will be activated according to the selected GPO state. This can be used to signal the PAGA system to temporarily mute loudspeakers and prevent acoustic feedback.

Note: Multiple rules can be configured for the same GPO/Relay, allowing a single relay output to be activated by multiple broadcast groups.

Relay 2 on IP-LCM 411 is triggered when broadcast group 842 is active

Operate a Relay When a Specific Operator Intercom Initiate a Live Broadcast

Navigate to Features > Advanced GPIO.

Select the device that provides the relay output.
Select the required GPO/Relay from the list.
In the GPO Rules pane, click the + icon to create a new rule.
Select the Outgoing Broadcast from Device rule type.
From the Directory Number drop-down list, select the operator intercom that should trigger the relay.
Set the desired GPO State:

On - The relay remains activated while the operator initiates a live broadcast.
Slow Flash - The relay output flashes at a slow rate while the operator initiates a live broadcast.
Fast Flash - The relay output flashes at a fast rate while the operator initiates a live broadcast.

When the selected operator intercom initiates a live broadcast, the configured relay output will be activated according to the selected GPO state. This can be used to signal the PAGA system to temporarily mute loudspeakers near the operator position and thereby prevent acoustic feedback.

Note: Multiple rules can be configured for the same GPO/Relay, allowing a single relay output to be activated by multiple operator intercoms. The relay will be activated whenever any of the configured operator intercoms performs a live broadcast.

Relay 3 on IP-LCM 411 is triggered whenever operator 146 initiates a live broadcast
