View source for Emergency group call with acknowledge

==Feature==
[[Image:WmergencyGroupWithAcknowledge.png|thumb|400px|Configuration example]]
A special group of stations receives emergency broadcast from a [[CRMIV]] or [[CRMV]] station. The members can be located in different nodes in AlphaNet. When the CRM station activates the emergency call, the corresponding LED's in the DAK module gives a red slow blinking. At the same time a display message is transmitted to the members. 

There is an acknowledge code to dial from the stations in the special group to tell the CRM that the member has acknowledged the emergency call. When the code is dialled the LED indication will change to steady green, and the display message will be cleared from that station. For those stations who don't acknowledge the call, the display message will remain in the station to indicate that the emergency call has been active while they were away.

A "Clear" code dialled on the CRM station will turn off all LED indications on the CRM, and remove the display information from all member stations.

==Configuration example==
Let us say that the members of the special group are:
*Node 1: Stations 101, 104, 105 and 106
*Node 2: Stations 201, 202 and 250
*Node 3: 401, 402 and 450

*The CRM directory number is 500. The station numbers above must be assigned to DAK keys on the CRM station.
*Include the stations in the local group 20 in each exchange, and include the local group 20 in global group 20. Assign a directory number to the global group 20, say 9020. The CRM station can now dial 9020 to do the emergency broadcast.

== Programming ==
==== Emergency Broadcast Activation ====
In the '''Exchange & System''' -> '''Events''' insert a new event:
[[Image:Emergeny call event 1.png|thumb]]
{| 
|-
|width="100pt"|'''Event Owner''':
|width="300pt"| The CRM IV station
|-
|'''Event type''': || 08 - Conversation Outgoing
|-
|'''Subevent''': || N/A
|-
|'''When change to''': || ON
|-
|'''When related to''': || Directory number, Id. 9020
|-
|valign="top"|'''Action''': || IND %1.phy %1.DAK(I101) 1 2 ON <br>
IND %1.phy %1.DAK(I104) 1 2 ON<br>
IND %1.phy %1.DAK(I105) 1 2 ON<br>
IND %1.phy %1.DAK(I106) 1 2 ON<br>
IND %1.phy %1.DAK(I201) 1 2 ON<br>
IND %1.phy %1.DAK(I202) 1 2 ON<br>
IND %1.phy %1.DAK(I250) 1 2 ON<br>
IND %1.phy %1.DAK(I401) 1 2 ON<br>
IND %1.phy %1.DAK(I402) 1 2 ON<br>
IND %1.phy %1.DAK(I450) 1 2 ON<br>
@U1 $SM %1.ref NG20 U119 NM17 GV U0 'Emergency' U0<br>
@U2 $SM %1.ref NG20 U119 NM17 GV U0 'Emergency' U0<br>
@U3 $SM %1.ref NG20 U119 NM17 GV U0 'Emergency' U0<br>
|-
|}
When the CRM dials the global group 9020 the [[IND|IND command]] will switch ON the red LED in the required DAK keys, and the [[SEND MAIL|SM command]] will send a mail message to stations in group 20 in each node 1, 2 and 3. The mail has priority 119, and the text 'Emergency' will be displayed. This event is programmed only in the node where the CRM station is located.

==== Acknowledge Code ====
In each exchange select the '''Directory & Features''' window, and create an Acknowledge Code, say 9590, with feature number 85/0.

In the '''Exchange & System''' -> '''Events''' create a new event which is triggered when the Acknowledge Code is dialled from any station. This event must be created in all exchanges:
[[Image:Emergeny call event 2.png|thumb]]
{| 
|-
|width="100pt"|'''Event Owner''':
|width="300pt"| Stations with UDP, UDP 8 (All stations)
|-
|'''Event type''': || 15 - Event Trigger Feature
|-
|'''Subevent''': || 0
|-
|'''When change to''': || ON
|-
|'''When related to''': || Directory number, Id: 9590
|-
|'''Action''': || @U1 $ER U15 U7 U1 U1 L500 U3 L%1.dir
|-
|}
When a station dials the acknowledge code an [[EVENT REPORT|ER (Event Report) command]] is sent to the node where the CRM is located (node 1 in this example), which will trigger an event type 15, subevent 7, When Change To: ON, Owner: 500, Related To: The dialling station.

==== Acknowledge Event ====
[[Image:Emergeny call event 3.png|thumb]]
'''Insert''' a new event with the following parameters:
{| 
|-
|width="100pt"|'''Event Owner''':
|width="300pt"| The CRM IV station
|-
|'''Event type''': || 07 - Conversation - Incoming
|-
|'''Subevent''': || N/A
|-
|'''When change to''': || ON or OFF
|-
|'''When related to''': || All
|-
|'''Action''': || [[IND]] %1.phy %1.dak(I%2.dir) 2 1
|-
|}
<br>

This will turn on the green led in the assosiated DAK key when an incoming call is received.

=== Buzzer ===
==== Priority Mail in Idle ====
[[Image:Emergeny call event 4.png|thumb]]
'''Insert''' a new event with the following parameters:
{| 
|-
|width="100pt"|'''Event Owner''':
|width="300pt"| The CRM IV station
|-
|'''Event type''': || 12 - Priority Mail in Idle
|-
|'''Subevent''': || N/A
|-
|'''When change to''': || ON or OFF
|-
|'''When related to''': || All
|-
| '''Action''': || [[IND]] %1.phy 1023 1 2
|-
|}
<br>

This will turn on the internal buzzer when a call request is received. The buzzer will be silent during conversartion.
