- FileName: Q931.h
-
- Contents: Header and definition for the ITU-T Q.931 stack. The
- header contents the following parts:
-
- - Definition of codes
- - Definition of information elements (Q931ie_).
- - Definition of messages (Q931mes_).
- - Definitian of variables (var_).
- - Function prototypes.
-
- Description: The Q.931 stack provided here covers ITU-T Q.931 w/Q.932
- supplementary services for both PRI, BRI and variants.
- The stack is generic and designed to deal with variants as
- needed.
-
- The stack uses the following interface functions:
-
- - Q931Initialize Initialize the Q.931 stack.
- - Q931Rx23 Receive a message from layer 2
- - Q931Tx32 Send a message to layer 2
- - Q931Rx43 Receive a message from layer 4 or above.
- - Q931Tx34 Send a message to layer 4 or above.
- - Q931TimeTick Periodical timer processing.
- - Q931ErrorProc Callback for stack error message.
-
- The protocol is a module with no external dependencies and
- can easely be ported to any operating system like Windows,
- Linux, rtos and others.
-
- Related Files: Q931.h Q.931 Definitions
- Q931.c Q.931 Interface Functions.
- Q931api.c Low level L4 API functions.
-
- Q932.h Q.932 Suplementary Services
- Q932mes.c Q.932 encoders/coders
-
- Q931mes.c Q.931 Message encoders/coders
- Q931ie.c Q.931 IE encoders/coders
- Q931StateTE.c Generic Q.931 TE State Engine
- Q931StateNT.c Generic Q.931 NT State Engine
-
- Design Note 1: For each variant please add separate files starting with
- the variant short-name as follows:
-
- <variant>.h Spesific headers needed.
- <variant>mes.c Message encoders/decores.
- <variant>ie.c IE encoders/decoders.
- <variant>StateTE.c TE side state engine.
- <variant>StateNT.c NT side state engine.
-
- Design Note 2: The stack is deliberatly made non-threading. Use 1
- thread per Trunk, but lock access from the timertick
- and rx, tx functions. And make sure the callbacks only
- dump messages to a queue, no time-consuming processing
- inside stack processing.
-
- All stack processing is async 'fire and forget', meaning
- that there are not, and should not be any time-consuming
- processing within the stack-time. The best way to thread
- a stack is to use one single thread that signal 5 queues.
-
- - Incoming L2 queue.
- - Incoming L4 queue.
- - Outgoing L2 queue.
- - Outgoing L4 queue.
- - Error/Trace queue.
-
- Design Note 3: DSP optimization. The L3 (Rx23) can be called directly
- from a hdlc receiver without usage of queues for optimized
- processing. But keep in mind that Q.931 calls Tx34 or Tx32
- as part of receiving a message from Layer 2.

+ Contents: Header and definition for the ITU-T Q.931 stack. The
+ header contents the following parts:
+
+ - Definition of codes
+ - Definition of information elements (Q931ie_).
+ - Definition of messages (Q931mes_).
+ - Definitian of variables (var_).
+ - Function prototypes.
+
+ Description: The Q.931 stack provided here covers ITU-T Q.931 w/Q.932
+ supplementary services for both PRI, BRI and variants.
+ The stack is generic and designed to deal with variants as
+ needed.
+
+ The stack uses the following interface functions:
+
+ - Q931Initialize Initialize the Q.931 stack.
+ - Q931Rx23 Receive a message from layer 2
+ - Q931Tx32 Send a message to layer 2
+ - Q931Rx43 Receive a message from layer 4 or above.
+ - Q931Tx34 Send a message to layer 4 or above.
+ - Q931TimeTick Periodical timer processing.
+ - Q931ErrorProc Callback for stack error message.
+
+ The protocol is a module with no external dependencies and
+ can easely be ported to any operating system like Windows,
+ Linux, rtos and others.
+

+ Q931ie.c Q.931 IE encoders/coders
+ Q931StateTE.c Generic Q.931 TE State Engine
+ Q931StateNT.c Generic Q.931 NT State Engine
+
+ Design Note 1: For each variant please add separate files starting with
+ the variant short-name as follows:
+
+ <variant>.h Spesific headers needed.
+ <variant>mes.c Message encoders/decores.
+ <variant>ie.c IE encoders/decoders.
+ <variant>StateTE.c TE side state engine.
+ <variant>StateNT.c NT side state engine.
+
+ Design Note 2: The stack is deliberatly made non-threading. Use 1
+ thread per Trunk, but lock access from the timertick
+ and rx, tx functions. And make sure the callbacks only
+ dump messages to a queue, no time-consuming processing
+ inside stack processing.
+
+ All stack processing is async 'fire and forget', meaning
+ that there are not, and should not be any time-consuming
+ processing within the stack-time. The best way to thread
+ a stack is to use one single thread that signal 5 queues.
+
+ - Incoming L2 queue.
+ - Incoming L4 queue.
+ - Outgoing L2 queue.
+ - Outgoing L4 queue.
+ - Error/Trace queue.
+
+ Design Note 3: DSP optimization. The L3 (Rx23) can be called directly
+ from a hdlc receiver without usage of queues for optimized
+ processing. But keep in mind that Q.931 calls Tx34 or Tx32
+ as part of receiving a message from Layer 2.
