The ICX-AlphaCom and AlphaCom XE servers are intercom servers of which the main task is to enable uni- and bi-directional speech. In order to be able to meet as many customer requirements as possible when it comes to special features an '''Event Handler''' has been implemented. The underlying idea is that by customer-programming this event handler functionality can be implemented which is not part of the standard [[AlphaCom Feature List|feature list]]. The event handler is unique in the world of intercom. It is what gives the server its flexibility and makes it possible to meet most, if not all, customer requirements.<br /> The Event Handler is based on the software concept that when the intercom functions run, they report 'events' to a part of the software called the Event Handler. The event can be described as a trigger that sets off an action in the system depending on the information entered in [[AlphaPro]], the programming tool for the ICX-AlphaCom. In this way, the Event Handler provides a powerful engineering tool for configuring system behavior to meet requirements from customers.

Actions can be simple, just to operate a relay under certain circumstances. Actions can also be programmed using a scripting language and can include conditional statements. An action can itself trigger a new event, making it possible to start a chain of actions.

=== Events ===
 +
'''Events''' are generated inside the ICX-AlphaCom software when interesting things happen. Events follows a fixed format, with the following parameters:
 +
* Owner
 +
* Event type
 +
* State change : ON/OFF
 +
* Related-to
  
 +
The '''owner''' is source which triggers the event. The following possible owners are defined:
  
 +
* A single '''station'''
 +
* A '''group of stations''' ([[UDP group]]) with common behavior
 +
* The '''[[Scheduler (Event Type)|scheduler]]''', the internal ICX-AlphaCom realtime clock
 +
* '''[[External Data Input]]''', a data port set up to receive ASCII text strings from external devices

Actions can be simple, just to operate a relay under certain circumstances. Actions can also be programmed using a scripting language and can include conditional statements. An action can itself trigger a new event, making it possible to start a chain of actions.  
+
The '''Event type''' is a number which tell what sort of event occurred. Event type is divided into a '''Main event''' and [[Sub-Event (Event Handler)|Sub-Event]]. Main events are listed below. Only some of the Main events use the Sub-Event. In the case of the scheduler the event is the ‘minute tick’.

Scheduling

For some features in AlphaNet, the owner of an event can be in a different node. Then the [[EVENT REPORT]] message sent to the owning exchange, where the event is processed. [[Conversation Outgoing (Event Type)|Conversation Outgoing]] is an example of such an event.

Event handler Rules are what you program in the [[Exchange_%26_System_%28AlphaPro%29#Events|Event Handler window]] in AlphaPro. An Eventhandler Rule has two main parts:
−
- Action strings
+
* A '''condition''', which matches specific Events
−
- Commands
+
* An '''action''', which specifies what should happen when a Event matches a Condition.
−
- Parameters and macro operations

- Statements

Event Handler technical description
+
Stations can trigger many different types of event.<br /> Many events can trigger an action when the event is activated and when the event is de-activated, for instance event type 07: Conversation – Incoming. The On/Off action can be differentiated by the ‘When Change To’ flag.<br /> Events can be, but don't have to be, related to a specific directory number or a group of stations, for instance:
  
−
The principal
+
* Owner: Station 1
−
An event has an owner, the source which triggers the event. The following possible owners are defined:
+
* Event: Conversation - Outgoing
 +
* Related to: Directory number 102
 +
* When change to: ON
 +
* Action: RCO 2 ON
  
−
A station. It is possible to group stations together by a UDP-flag in order to give such a group common behaviour.
 
−
The scheduler, the internal AlphaCom clock which generates a ‘tick’ every minute.
 
−
In the case of the scheduler the event is the ‘minute tick’. Stations can trigger many different types of event.
 
−
Many events can trigger an action when the event is activated and when the event is de-activated, for instance event type 07: Conversation – Incoming. The On/Off action can be differentiated by the ‘When Change To’ flag.
 
−
Events can be, but don't have to be, related to a specific directory number or a group of stations, for instance:
 
−
 
−
Owner: Station 1
 
−
Event: Conversation - Outgoing
 
−
Related to: Directory number 102
 
−
When change to: ON
 
−
Action: RCO 2 ON
 
 
In this case the relay connected to RCO 2 will only be activated if 'Station 1' is in conversation with a station with directory nr 102, AND if Station 1 was the station which made the call. If 'Related to' was not specified, that same relay would be activated on any call which Station 1 would make.

Events

== Events Types ==
−
An event is a trigger that sets off an action in the system. An event can be:
+
The list shows the available '''event types''', grouped by function.<br><br>
−
 
 
−
An internal audio event in the program
 
−
An event triggered by some external device
 
−
An exchange feature
 
−
An internal error report (for instance 'station disconnected')
 
−
A data protocol command
 
−
An event can set off an action that can control:
 
−
 
 
−
Some external hardware through an RCO output
 
−
A defined action or a set of actions in the system software
 
−
A data command to the exchange itself (this gives the possibility to use all AlphaNet dataprotocol commands to control what happens)
 
−
A data command to another exchange
 
−
A data command to external equipment
 
−
Event triggers which have a station as event owner
 
−
Audio : type 01
 
−
The audio events are intended for PA control or mobile radio keying, that is, as an extension to the audio function of the 'owner' station. Normally the action for this event is the operation of an RCO. The Audio event is divided into a number of sub-events, which are closely related to each other, and which can be combined to operate the same RCO.
 
−
User Defined Properties (UDP's) cannot be used with Audio events.
 
−
Audio events are not associated with a 'related to' number.
 
−
In AlphaPro the sub-events can be selected after clicking the 'Details'-button.
 
−
 
 
−
Always: Both incoming and outgoing calls:
 
−
Simplex listen (release own M-key, or conversation partner presses the M-key)
 
−
Tones
 
−
Sending Gong (this station makes a group call)
 
−
Voice message
 
−
The station state must be: Handset ON or Volume / Handset override.
 
−
 
 
−
Application:
 
−
 
 
−
Non-selective mobile radio, PA
 
−
Incoming call:
 
−
Incoming Simplex listen (release own M-key, or conversation partner presses the M-key)
 
−
Tones
 
−
The station state must be:
 
−
 
 
−
Incoming call
 
−
Handset ON or Volume/Handset Override
 
−
Note: The event is reported OFF (and stays OFF) if the user touches any key or the handset. This is called 'take down', as it is intended to transfer an incoming call from an external RCO-controlled speaker to the station’s internal speaker when the user touches any key or the handset.
 
−
 
 
−
Private ringing: Incoming call only:
 
−
Ringing tone (on/off for each tone period)
 
−
The station state must be:
 
  
−
Incoming call

=== Data Protocol Commands ===
−
This owner dials a directory number with feature 59 (code lock).
 
−
The event reports an ON and an OFF transition. ON when the feature is dialled, OFF after a period as set for the timer ‘RCO pulse time’.
 
−
This event has no ‘related to’ relationship.
 
  
−
Station in use : type 04
+
'''Data Protocol Commands''' are using ACDP commands on the [[Stentofon Simple Link Layer|Simple Link Layer]] format. The commands begin with $ or @.
−
Whenever the station is busy.
 
−
This event has no ‘related to’ relationship.
 
  
−
Microphone open : type 05
+
The most relevant data protocol commands for the Event Handler and for [[RCI]]s are listed in the table below. Follow this link for a complete list of [[AlphaNet_Data_Protocol#Message_Formats_-_Grouped_by_Function|all Data Protocol Commands]]
−
Whenever the station LED is lit.  
 
−
Do not use this to indicate conversation, as the event will go OFF in many situations; also, it will be ON when feeding a Group Call, Simplex Conference etc.
 
−
This event has no ‘related to’ relationship.
 
  
−
Priority mail present : type 06
 
−
There is at least one mail with priority above 100 (programmable as a global value ‘Priority Mail Queue Indication’) in the mail queue of the owner.
 
−
Notes:
 
  
−
The event occurs every time a mail enters the queue, that is, there are many ON events followed by one OFF.  
+
{| border="1"
−
The event also stays ON during connections. Not well suited as a buzzer control.
+
! style="background:#ffdead;" width="170" |Message
−
The event can be temporarily switched OFF/ON by dialling 7882 (which toggles the event). It will then stay OFF until the mail queue is emptied, and another priority mail arrives.

−
Conversation – Incoming : type 07
+
<br>
−
This event reports ON when a connection is established and OFF on disconnection. The event is reported when the owner receives a call. The event can be related to specific calling stations.
+
<br>
  
−
Conversation – Outgoing : type 08
+
== Context Parameters and macros ==
−
This event reports ON when a connection is established and OFF on disconnection. The event is reported when the owner makes a call. The event can be related to specific called stations.
 
  
−
Private ringing mode : type 09
+
[[#Action Commands|Action commands]] used in the Event Handler can contain '''context parameters''' and '''macros'''. They both return a value.  
−
Incoming private ringing (or call transfer ringing). The event goes ON at the start of the ringing, and OFF when the station enters conversation, or ringing stops due to time-out or C-key.
 
−
The event can be related to specific calling stations.
 
  
−
Received mail : type 10
+
'''Context Parameters''' are related to the actual event, and refer to the involved station(s) or functions. A parameter always starts with the character "%". Context parameters are useful for defining the action of a rule where the condition is a [[UDP_group]].
−
Occurs for each mail entering the owner station queue. The event goes ON when the mail is put into the queue, and OFF when removed from the queue.
 
−
The event can be related to specific stations sending mail.
 
  
−
Call requester mode : type 11
+
*'''%1''': the parameter is associated with the ''Owner'' field
−
Occurs when this station dials a Call Request, which sends a mail to another station’s mail queue. The event goes ON when the station has been put into the queue, and OFF when either the entry is deleted from the queue, or the station has been used for something. This event is then active while the station has voice message/flash/ringing.
+
*'''%2''': the parameter is associated with the ''Related to'' field
−
As the event is reported OFF as soon as the station is used for anything, even if only the C-key has been pressed, this event cannot be used to reliably indicate whether this station has originated a call request which has not been answered yet.
+
*'''%3''': the parameter is associated with the ''When change to'' field
−
The event can be related to specific stations in which queue the mail is put. As from AMC-software 9.05 the 'related to' parameter can be a UDP-flag.
 
  
−
Priority mail in idle : type 12
+
A '''macro''' is unrelated to the event itself. It reads information from the memory (nvram) or performs a calculation. Also a macro always starts with the character "%".  
−
Behaves as ‘priority mail present’ above, but is switched OFF during connections and back ON every time the station becomes idle. As such it is well suited to switch on and off audible indicators, which should be silent during an established connection.
 
−
This event has no ‘related to’ relationship.
 
  
−
Faulty station line : type 13
+
Macros and parameters can be nested freely, and makes it possible to build complicated expressions.
−
Occurs if the owner’s line monitoring has found a problem or if the whole line board becomes faulty.
 
−
There is also a ‘faulty station’ indication on the exchange level, which becomes active if one or more stations are faulty. The main difference is that this event also reports the OFF status (indication that the problem has been resolved), while the report on exchange level only reports the event ON status.
 
−
This event has no ‘related to’ relationship.
 
  
−
Event Trigger Feature : type 15
+
=== List of context parameters ===
−
The owner station dials a directory number with feature 52 (event trigger without tone) or 85 (event trigger with cancel tone) which triggers the defined events. When the event is triggered by physically dialling the ‘related to’ directory number, the event can only report an ON status. If the event is triggered from a data protocol message, it is also possible to report an OFF status.
 
−
The field ‘sub-type’ can be used to group event triggers. This field is associated with the parameter (ID) field of the feature. This means that a number of event trigger directory numbers can be defined with the same parameter. If the ‘related to’ field is set to ‘ALL’ and the ‘sub-type’ field is set to that same parameter value, all these directory numbers will trigger the same event.
 
−
When used in conjunction with the data protocol message $ER, the owner does not need to be a physical station, but can be a dummy (non-existent) station. This can be useful when an RCI needs to trigger a lengthy action string, which exceeds the allowed length for the RCI action string itself. The action string for the RCI can then be an event report on a dummy station, where the real actions are performed on the event trigger on this dummy station.
 
−
The event is also triggered on dialling a directory number with feature 95 (Event trigger with user parameter). In this case the event reports ON when the event directory number has been dialled and OFF when the event is ‘disconnected’. In the case of feature 95, this is useful functionality. Feature 95 directory numbers do not disconnect immediately after connection (like feature 52 or 85 directory numbers), but either time out after 20 seconds, or can be disconnected via a data protocol message $DISCON_ST.
 
−
The event must be related to a directory number which triggers the event.
 
  
−
Simplex Conference Audio : type 16
+
{| border="1" class="sortable"
−
Occurs on all stations which are members of a simplex conference, when audio is present in the conference. Normally, the event is triggered by an RCI with a $VOX data protocol message in the action string.
+

Mail Timeout : type 20
+
=== Formatting ===
−
A timer can be set on a mail event by using the command $SMT (SET_MAIL_TIMEOUT). When the timer expires a ‘Mail Timeout’ event is reported. The event must have an owner. The timer can be set with a ‘related to’ parameter. This parameter is reported and can be used as the %2 parameter in an action string.
+
Text adjustment parameters can be added to all %xxx macros
−
This event can be used for instance to higher the priority level of a call request, if the request is not ansered within a certain period. This period is set by the time-parameter of the $SMT-command.
+
;%xxx(width,filler)
 +
:'''width''': Length of field
 +
::If ‘<’ is put immediately after the width, it means left-adjustment. Default is right adjustment

::Typical fillers are
 +
:::”  ” (space)
 +
:::”0” (leading zero)
 +
:::”F” (MPC protocol)
 +
::The filler can be omitted: %xxx(width). Then ”  ” (space) will be used as filler if required. It is not allowed with space between the formatting parameters
  
−
Event Timeout : type 21
 
−
A timer can be set with the data protocol command $ST (SET_TIMER). When the timer expires, the event ‘Event Timeout’ is reported. The event must have an owner. If a time out period not intended for a specific station is required, a dummy station can be used as owner.
 
−
The timer can be set with a ‘related to’ parameter. This parameter is reported and can be used as the %2 parameter in an action string.

New Current mail in station queue : type 23
+
'''Examples:'''
−
An event is reported each time the current mail in a station queue is changed. Reported both when change due to manual browsing or due to a new high priority mail first in queue, or that the current mail is deleted. The ON report is sent 0,5 second after browsing to a new mail element. The event is also repeated when stopping at the end of the queue. The event is reported OFF when the current mail is left due to any reason.
 
−
%1 is the queuing station, %2 is the mail sender. %TAG included.
 
−
The delay on the on-report is programmable in NVRAM: timeouts.mail_event_delay
 
  
−
New first mail in station queue : type 24
+
'''%1.dir'''
−
Reported when a new mail arrives first in a stations queue. Only reported ON. Will not be reported when the second mail becomes first because the first was deleted. It can be used to start a buzzer when the first request arrives, or when a higher priority request arrives.
+
Minimum:         %1.dir        - Example result:  “123”
−
%1 is the queuing station; %2 is the mail sender. %TAG included.
+
MPC format:      %1.dir(4,F)  - Example result:  “F123”
 +
Two last digits: %1.dir(2)    - Example result:  “23”
  
−
Event Trigger with User Parameter : type 25
+
'''%1.nam'''
−
This event can be triggered from directory numbers associated with different features. The behaviour is different for these 2 features.
+
Minimum:          %1.nam      - “Mr. Smith”
 +
5 last characters: %1.nam(5)  - “Smith”
 +
12 char, right :   %1.nam(12)  - “  Mr. Smith”
 +
12 char, left :    %1.nam(12<) - “Mr. Smith  ”
  
−
Feature 95, which allows the user (the event owner) to dial a directory number as parameter: The user first dials the feature code for the event trigger. Then the user is supposed to dial a directory number. After the directory number is dialled, this event is triggered. The %1 parameter is the station where the function is dialled; %2 is the dialled directory number.

The event sub-type in the Event Report is set to the value of the parameter-attribute of the Event Trigger directory number. This can be used to define several user-defined actions.
+
%udd(12)        - “65”
−
The feature does not disconnect after the event has been triggered. The station just hangs silently, until it disconnects after 20 seconds. The data protocol message $DISCON_ST can be used to make the station disconnect with the selected tone. The Event Handler programmer can then control the feedback to the user, using this message in combination with the $DISPLAY_TEXT message.
+
%udd(12,4)      - “  65”
−
The user can also dial more than one directory number. An event is triggered for each directory number dialled; %2 is the dialled directory number. This can be used to make 'dynamic grouping' functions, see example.
+
%udd(12,4<)      - “65  ” 
−
An Event Report is also generated immediately after the initial feature code is dialled: ‘Event Trigger Start with User Parameter’, see below.
+
%udd(12,4,f)     - “ff65” 
−
The Event Trigger Feature number 15 event is also reported, with the %2 parameter set to the directory number of the event trigger feature. The events reports ON when the event trigger has been dialled and OFF when the feature is disconnected (the Event sub-type is always ‘0’).
+
%udd(12,4<,f)   - “65ff”
−
Feature 105. When activating this feature all succeeding digits are reported to the event handler and trigger this event where the event sub-type is equal to the digits dialled 0-9. The event is ON as long as the station key is down and reported OFF when key is released, which can for instance be used for camera control from the station keyboard, see example.
 
−
Directory numbers assigned FEAT_DIGIT_EVENT (105) with the parameter-attribute set to ‘0’ display the digit while it is held down in the second line of the station display; if the parameter-attribute is different from ‘0’ the display is not updated and can be updated by the event handler to indicate ‘left’, ‘up’, ‘on’, etc….
 
−
The features times out after 20 seconds after the last pressed digit.
 
−
The digit press on a CRM4 is only reported ON for a few hundred milliseconds. The digit release is handled by the internal station software and is not dependent on the physical length of the button press.
 
−
Event Trigger Start with User Parameter : type 26
 
−
An event trigger feature, triggered after dialling a directory number with feature 95. It is closely associated with the event trigger as described above.
 
−
It is generated immediately after the initial feature code is dialled. The %1 parameter is the station where the function is dialled (the owner). If the station has mail in its queue, the %2 parameter is set to the sender of the current mail. Otherwise %2 is empty.
 
  
−
System Event : type 27
+
'''%clk'''  
−
Event type 27 is triggered by system events. In the AMC software, %1 is hardcoded to physical station 1. The event does not recognise a 'related to' parameter. In AlphaPro 'When Related To' must be set to 'All'.
+
Minimum:          %clk      - “2009-10-16 12:59:35”
−
- Sub-event 1-208 are used for device up/down reports.
+
8 last characters: %clk(8)   - “12:59:35”
−
- Sub-events 65-68 (exchange modules) use the global timer 'start_evn_delay' (default value '1') before the event is triggered ON. There is no delay for the event OFF trigger. The ON event is triggered when all cards are scanned.
+
10 char, left :    %clk(10<) - “2009-10-16”
−
- Sub-events 210-217 are used for serial ports 1-7 up/down reports, but only for ports in multi-module or AlphaNet mode. 
 
  
−
Scheduling
+
===Free text===
−
Scheduling is to program the AlphaCom to do actions at specified hours, weekdays or dates.
+
A free text in built-in event handler commands are written in double quotes "".
−
Scheduling is an extension to the Event Handler and is defined as type 22.
 
−
Each minute a MINUTE_TICK event is generated, with the current time as parameter. Scheduling rules consists of a time condition and a normal Event Handler action. There are two variants of time conditions:
 
  
−
Date and time: yy-mm-dd hh:mm. Each digit can be a wild card *, matching all tick-values in that position.
+
<br<br>
−
Example: The rule '**-**-** 12:00' will be triggered every day at 12:00.
 
−
List of weekdays and a time: mtwtfss hh:mm. In AlphaPro there is a checkbox for each weekday. Each digit in the time can be a wild card *.
 
−
Example: The rule mtwtf-- **-**-** **:00 will be triggered every hour Monday to Friday.
 
−
For each MINUTE_TICK event the tick time is matched against all scheduling rules. All matching rules are executed.
 
−
During normal operation the minute tick is executed between 1 and 2 seconds after start of the minute.
 
−
In order to not miss important actions while the exchange is down, or if the clock is moved forward, there is a time catch-up mechanism to handle this.
 
  
−
The last generated minute tick is stored in NVRAM.
+
=== Comments ===
−
Up to 24 hours are caught up after a power off, or after the real-time clock has been set forward.
+
The Event Handler allows line comments by prefixing the line with an exclamation mark (!).
−
-One minute tick is generated every second until the scheduling tick time has caught up with real time (can take up to 24 minutes). During this period the scheduling time is different from real time.
 
−
During normal operation the MINUTE_TICK event is generated with the change-flag set to ON. During catch-up the change is set to OFF. In this way catch-up ticks can be filtered away. The %chg() parameter can be used in the action string to test if it is a normal operation or catch-up.
 
−
As from AMC software version 9.05 it is possible to use the 'When Change To' flag to trigger the event depending on the type of minute tick:
 
−
- ON : the event will be triggered on 'real' ticks
 
−
- OFF : the event will be triggered on 'catch-up' ticks
 
−
- ON or OFF : the event will be triggered on both types of ticks.
 
−
If the clock is set backwards, (e.g. daylight saving time at autumn), the scheduling time is set back immediately, and the ticks are performed as normal during the overlapping period.
 
−
%1.clk, %1.clkmin %1.clkhour parameters etc. will return the scheduling tick time, not the real time if used within a Scheduling action.
 
−
%clk (without the '1.') will always return the real time.
 
−
In AlphaPro the time and date of an event is stored in the 'ID' and 'related to' fields. In this case 'ID' and 'related to' must be viewed in a different way compared to when the owner of an event is a station. 'ID' and 'related to' are merely a convenient place to store the parameters.
 
  
−
Event actions
+
Any line in the event handler starting with ! will not be executed. This does not support inline comments.
−
There are 2 types of action:
 
  
−
An action string which can be entered in the ‘Command-filed’ as ASCII characters
+
{{note|Comments are supported as from AlphaCom sw 13.1.3.1}}
−
An action on an RCO
 
−
RCO
 
−
When an RCO is selected from the drop-down list, the event will operate that specific RCO. The RCO-status will follow the 'change'-status as follows:
 
  
−
'ON' selected: The RCO will be made active when the ON-action of the event is triggered
+
Example:
−
'OFF' selected: The RCO will be de-activated when the OFF-action of the event is triggered
+
IF %busy(4)
−
'ON or OFF' selected: The RCO status will follow the 'change'-status; activated for ON, de-activated for OFF
+
!Station 4 is busy
−
Action strings
+
stop
−
As an alternative to the above RCO-operation it is also possible to enter a command-string in the action-field.
+
ENDIF
−
An action string can contain:
+
!Station 4 is free
 +
$CALL L101 L104
  
−
Command (internal commands and data protocol messages)
+
<br><br>
−
Parameters and Macro operations
 
−
Statements and Conditions
 
−
Action strings are stored in multiples of 16 bytes. A new action string always starts on a 16-byte boundary. This means that if all action strings have a maximum of 16 characters, it is possible to define 2000 action strings.
 
  
−
Commands
+
===Escape sequences===
−
The commands can be internal commands and data protocol messages. The internal commands are:
+
[[Character escape codes|Escape sequences]] can be used for two purposes:

Event Handler - Block Diagram

The ICX-AlphaCom and AlphaCom XE servers are intercom servers of which the main task is to enable uni- and bi-directional speech. In order to be able to meet as many customer requirements as possible when it comes to special features an Event Handler has been implemented. The underlying idea is that by customer-programming this event handler functionality can be implemented which is not part of the standard feature list. The event handler is unique in the world of intercom. It is what gives the server its flexibility and makes it possible to meet most, if not all, customer requirements.
The Event Handler is based on the software concept that when the intercom functions run, they report 'events' to a part of the software called the Event Handler. The event can be described as a trigger that sets off an action in the system depending on the information entered in AlphaPro, the programming tool for the ICX-AlphaCom. In this way, the Event Handler provides a powerful engineering tool for configuring system behavior to meet requirements from customers.

Actions can be simple, just to operate a relay under certain circumstances. Actions can also be programmed using a scripting language and can include conditional statements. An action can itself trigger a new event, making it possible to start a chain of actions.

The principle

Events

Events are generated inside the ICX-AlphaCom software when interesting things happen. Events follows a fixed format, with the following parameters:

  • Owner
  • Event type
  • State change : ON/OFF
  • Related-to

The owner is source which triggers the event. The following possible owners are defined:

  • A single station
  • A group of stations (UDP group) with common behavior
  • The scheduler, the internal ICX-AlphaCom realtime clock
  • External Data Input, a data port set up to receive ASCII text strings from external devices

The Event type is a number which tell what sort of event occurred. Event type is divided into a Main event and Sub-Event. Main events are listed below. Only some of the Main events use the Sub-Event. In the case of the scheduler the event is the ‘minute tick’.

State change: Most of the events are modeled as a state which goes ON and OFF. But some events does not fit to that concept, then only a ON event is reported.

Related-to is specific for the feature which reports the event. It can be the other station in a conversation, or the sending station of a mail or CallRequest.

For some features in AlphaNet, the owner of an event can be in a different node. Then the EVENT REPORT message sent to the owning exchange, where the event is processed. Conversation Outgoing is an example of such an event.

Event Rules

Event handler Rules are what you program in the Event Handler window in AlphaPro. An Eventhandler Rule has two main parts:

  • A condition, which matches specific Events
  • An action, which specifies what should happen when a Event matches a Condition.

Stations can trigger many different types of event.
Many events can trigger an action when the event is activated and when the event is de-activated, for instance event type 07: Conversation – Incoming. The On/Off action can be differentiated by the ‘When Change To’ flag.
Events can be, but don't have to be, related to a specific directory number or a group of stations, for instance:

  • Owner: Station 1
  • Event: Conversation - Outgoing
  • Related to: Directory number 102
  • When change to: ON
  • Action: RCO 2 ON

In this case the relay connected to RCO 2 will only be activated if 'Station 1' is in conversation with a station with directory nr 102, AND if Station 1 was the station which made the call. If 'Related to' was not specified, that same relay would be activated on any call which Station 1 would make.

Action Commands

There are two types of Action Commands which can be used by the Event Handler, Built-In Action Commands and Data Protocol Commands.

Both types of commands can include parameters and macros (e.g. %1.dir and %clk(8))

Built-In Action Commands

Built-in Action Commands are three- or four-letter commands. The commands are case-insensitive as from AMC 08.20. Most of the Built-In commands also have a Data Protocol implementation.

Context Parameters and macros

Action commands used in the Event Handler can contain context parameters and macros. They both return a value.

Context Parameters are related to the actual event, and refer to the involved station(s) or functions. A parameter always starts with the character "%". Context parameters are useful for defining the action of a rule where the condition is a UDP_group.

  • %1: the parameter is associated with the Owner field
  • %2: the parameter is associated with the Related to field
  • %3: the parameter is associated with the When change to field

A macro is unrelated to the event itself. It reads information from the memory (nvram) or performs a calculation. Also a macro always starts with the character "%".

Macros and parameters can be nested freely, and makes it possible to build complicated expressions.

List of context parameters

Parameter Short name Returned value From version
%1.phy %1p The physical number AMC 07.20
%1.dir %1d The directory number  
%1.nam %1n The name (display text) AMC 08.00
%1.exp %1e The User defined parameter  
%1.udp   The UDP group memberships for station AMC 10.21
%1.dak %1k The number of the DAK key containing a specified string AMC 08.00
%1.nod   The node number AMC 08.03

%chg		 %3c %chg(ON_txt,OFF_txt) returns "ON_txt" when the event goes ON, "OFF_txt" when the event goes OFF
Example: LOG “Door %1.dir is %chg(OPEN ,CLOSED)“
Result, event ON: - “Door 123 is OPEN ”
Result, event OFF: - “Door 123 is CLOSED” 		AMC 07.20
%3.rft
%rft		 %3r Action command parameter which substitutes the parameter with a text describing the on/off transition of the event. Some events can be reported many times (e.g. line errors), and it's possible to have different actions depending on if this is the first time, or a Refresh.
%rft(normal_text,refresh_text) returns <refresh_text> if this is a refresh transition. <normal_text> otherwise.		  
%sev   Read sub-event number AMC 09.03
%edi   Read EDI text input AMC 10.00

Formatting

Text adjustment parameters can be added to all %xxx macros

%xxx(width,filler)
width: Length of field
If ‘<’ is put immediately after the width, it means left-adjustment. Default is right adjustment
filler: If width is wider than the returned value, the specified filler character is filled in
Typical fillers are
” ” (space)
”0” (leading zero)
”F” (MPC protocol)
The filler can be omitted: %xxx(width). Then ” ” (space) will be used as filler if required. It is not allowed with space between the formatting parameters


Examples:

%1.dir 

Minimum:         %1.dir        - Example result:  “123”
MPC format:      %1.dir(4,F)   - Example result:  “F123”
Two last digits: %1.dir(2)     - Example result:  “23”

%1.nam 

Minimum:           %1.nam      - “Mr. Smith”
5 last characters: %1.nam(5)   - “Smith”
12 char, right :   %1.nam(12)  - “   Mr. Smith”

Free text

A free text in built-in event handler commands are written in double quotes "".

<br

Comments

The Event Handler allows line comments by prefixing the line with an exclamation mark (!).

Any line in the event handler starting with ! will not be executed. This does not support inline comments.

Note icon Comments are supported as from AlphaCom sw 13.1.3.1


Example: 

IF %busy(4)
!Station 4 is busy
stop
ENDIF
!Station 4 is free
$CALL L101 L104



Escape sequences

Escape sequences can be used for two purposes:

  • to use non-printable characters in action strings
  • quoting: ignore special meaning of a character in eventhandler parser.

Some frequently used escape sequences: 

\r = Carriage Return
\n = Line Feed 
\xhh = hh is any ASCII value in HEX

Some ASCII values: 

\x0D = Carriage Return (CR)
\x0A = Line Feed (LF)
\x02 = Start of Text (STX)
\x03 = End of Text (ETX)
\x06 = ACK
