The AlphaCom exchange is an intercom exchange 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 exchange 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 AlphaCom exchange. In this way, the Event Handler provides a powerful engineering tool for configuring system behaviour 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 principal===

== The principle ==
An event has an '''owner''', the source which triggers the event. The following possible owners are defined:
+
=== 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 single '''station'''
* A '''group of stations''' ([[UDP group]]) with common behaviour
+
* A '''group of stations''' ([[UDP group]]) with common behavior
* The '''scheduler''', the internal AlphaCom clock which generates a ‘tick’ every minute
+
* The '''[[Scheduler (Event Type)|scheduler]]''', the internal ICX-AlphaCom realtime clock
* '''EDI Text''', a data port set up to receive ASCII text strings from external devices
+
* '''[[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 (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’.
 +
 
 +
'''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.
  
In the case of the scheduler the event is the ‘minute tick’. 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:
+
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 Rules===
 +
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:
 +
* 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.<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:
  
 
* Owner: Station 1
 
* Owner: Station 1

== Context Parameters and macros ==
 +
 
 +
[[#Action Commands|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.

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

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”

8 last characters: %clk(8)   - “12:59:35”
10 char, left :    %clk(10<) - “2009-10-16”

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
