Literal PDU

 Set of lines which can be edited in ASN1 notation, according to the syntax of the literal form of the PDU type in use.
The Copy/Paste functions can be used, to import, export, duplicate...
The content can be automatically regenerated from the Hex PDU.
It can include an hex sequence, followed by its significant decoding including lines beginning with '--'.

Hex PDU:
Length:

 Sequence of octets in hexadecimal form, whose length is displayed.
The Copy/Paste functions can be used, to import, export, duplicate...
The content can be automatically regenerated from the Literal PDU.

Get matching brace

 To find the paired braces (successive opening and closing ones).

Encode literal PDU

 To encode and generate the Hex PDU content from the Literal PDU.

Decode hex PDU

 To decode and generate the Literal PDU content from the Hex PDU according to the chosen PDU type.
If there are any errors, PER display format is used.

Decode selected PDU

 Within the Literal PDU content, the highlighted hex sequence will be decoded in a secondary H323 Encoder window according to the chosen PDU type.
If any error, the PER display format is used.

Show debug trace

 Option to use PER display format when applying decode hex PDU.

No

 ASN1 notation is used, providing there are no decoding errors.

Yes

 PER display format is used.

The Clarinet emulator's own IP address will be automatically put in place of the IP address value '00000000'H (as 0.0.0.0).
The IP address can be modified to a different value, which will be preserved.


Decoding selected PDU

The IP address can be modified to a different value.

If you make any modifications to the literal PDU content, you must re-encode the ASN1 content by clicking Encode literal PDU before clicking OK.
