-- ANNEX A: BINARY ENCODING OF THE PROTOCOL (NORMATIVE)
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
--
-- This Annex specifies the syntax of messages using the notation
-- defined in ASN.1 [ITU-T Recommendation X.680 (1997): Information
-- Technology - Abstract Syntax Notation One (ASN.1) - Specification of
-- basic notation.]. Messages shall be encoded for transmission by
-- applying the basic encoding rules specified in [ITU-T Recommendation
-- X.690(1994) Information Technology - ASN.1 Encoding Rules:
-- Specification of Basic Encoding Rules (BER)].
--
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
-- A.1 Coding of wildcards
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
--
-- The use of wildcards ALL and CHOOSE is allowed in the protocol.
-- This allows a MGC to partially specify Termination IDs and let the
-- MG choose from the values that conform to the partial specification.
-- Termination IDs may encode a hierarchy of names. This hierarchy is
-- provisioned. For instance, a TerminationID may consist of a trunk
-- group, a trunk within the group and a circuit. Wildcarding must be
-- possible at all levels. The following paragraphs explain how this
-- is achieved.
--
-- The ASN.1 description uses octet strings of up to 8 octets in length
-- for Termination IDs. This means that Termination IDs consist of at
-- most 64 bits. A fully specified Termination ID may be preceded by a
-- sequence of wildcarding fields. A wildcarding field is one octet in
-- length. Bit 7 (the most significant bit) of this octet specifies
-- what type of wildcarding is invoked: if the bit value equals 1,
-- then the ALL wildcard is used; if the bit value if 0, then the
-- CHOOSE wildcard is used. Bit 6 of the wildcarding field specifies
-- whether the wildcarding pertains to one level in the hierarchical
-- naming scheme (bit value 0) or to the level of the hierarchy
-- specified in the wildcarding field plus all lower levels (bit value
-- 1). Bits 0 through 5 of the wildcarding field specify the bit
-- position in the Termination ID at which the starts.
--
-- We illustrate this scheme with some examples. In these examples,
-- the most significant bit in a string of bits appears on the left
-- hand side.
--
-- Assume that Termination IDs are three octets long and that each
-- octet represents a level in a hierarchical naming scheme. A valid
-- Termination ID is
-- 00000001 00011110 01010101.
--
-- Addressing ALL names with prefix 00000001 00011110 is done as
-- follows:
-- wildcarding field: 10000111
-- Termination ID: 00000001 00011110 xxxxxxxx.
--
-- The values of the bits labeled "x" is irrelevant and shall be
-- ignored by the receiver.
--
-- Indicating to the receiver that is must choose a name with 00011110
-- as the second octet is done as follows:
-- wildcarding fields: 00010111 followed by 00000111
-- Termination ID: xxxxxxxx 00011110 xxxxxxxx.
--
-- The first wildcard field indicates a CHOOSE wildcard for the level
-- in the naming hierarchy starting at bit 23, the highest level in our
-- assumed naming scheme. The second wildcard field indicates a CHOOSE
-- wildcard for the level in the naming hierarchy starting at bit 7,
-- the lowest level in our assumed naming scheme.
--
-- Finally, a CHOOSE-wildcarded name with the highest level of the name
-- equal to 00000001 is specified as follows:
-- wildcard field: 01001111
-- Termination ID: 0000001 xxxxxxxx xxxxxxxx .
--
-- Bit value 1 at bit position 6 of the first octet of the wildcard
-- field indicates that the wildcarding pertains to the specified level
-- in the naming hierarchy and all lower levels.
--
-- Context IDs may also be wildcarded. In the case of Context IDs,
-- however, specifying partial names is not allowed. Context ID 0x0
-- SHALL be used to indicate the NULL Context, Context ID 0xFFFFFFFE
-- SHALL be used to indicate a CHOOSE wildcard, and Context ID
-- 0xFFFFFFFF SHALL be used to indicate an ALL wildcard.
--
-- TerminationID 0xFFFFFFFFFFFFFFFF SHALL be used to indicate the ROOT
-- Termination.
--
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
-- Digit maps and path names
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
--
-- From a syntactic viewpoint, digit maps are strings with syntactic
-- restrictions imposed upon them. The syntax of valid digit maps is
-- specified in ABNF [RFC 2234]. The syntax for digit maps presented
-- in this section is for illustrative purposes only. The definition of
-- digitMap in Annex B takes precedence in the case of differences
-- between the two.
--
-- digitMap = (digitString / LWSP "(" LWSP digitStringList LWSP ")"
-- LWSP)
-- digitStringList = digitString *( LWSP "/" LWSP digitString )
-- digitString = 1*(digitStringElement)
-- digitStringElement = digitPosition [DOT]
-- digitPosition = digitMapLetter / digitMapRange
-- digitMapRange = ("x" / LWSP "[" LWSP digitLetter LWSP "]" LWSP)
-- digitLetter = *((DIGIT "-" DIGIT) /digitMapLetter)
-- digitMapLetter = DIGIT ;digits 0-9
-- / %x41-4B / %x61-6B ;a-k and A-K
-- / "L" / "S" ;Inter-event timers
-- ;(long, short)
-- / "Z" ;Long duration event
-- DOT = %x2E ; "."
-- LWSP = *(WSP / COMMENT / EOL)
-- WSP = SP / HTAB
-- COMMENT = ";" *(SafeChar / RestChar / WSP) EOL
-- EOL = (CR [LF]) / LF
-- SP = %x20
-- HTAB = %x09
-- CR = %x0D
-- LF = %x0A
-- SafeChar = DIGIT / ALPHA / "+" / "-" / "&" / "!" / "_" / "/" /
-- "'" / "?" / "@" / "^" / "`" / "~" / "*" / "$" / "\" /
-- "(" / ")" / "%" / "."
-- RestChar = ";" / "[" / "]" / "{" / "}" / ":" / "," / "#" /
-- "<" / ">" / "=" / %x22
-- DIGIT = %x30-39 ; digits 0 through 9
-- ALPHA = %x41-5A / %x61-7A ; A-Z, a-z
-- A path name is also a string with syntactic restrictions imposed
-- upon it. The ABNF production defining it is copied from Annex B.
--
-- PathName = NAME *(["/"] ["*"] ["@"] (ALPHA / DIGIT)) ["*"]
-- NAME = ALPHA *63(ALPHA / DIGIT / "_" )
--

-- A.2 ASN.1 syntax specification
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
--
-- This section contains the ASN.1 specification of the H.248 protocol
-- syntax.
--
-- NOTE - In case a transport mechanism is used that employs
-- application level framing, the definition of Transaction below
-- changes. Refer to the annex defining the transport mechanism for
-- the definition that applies in that case.
--
-- NOTE - The ASN.1 specification below contains a clause defining
-- TerminationIDList as a sequence of TerminationIDs. The length of
-- this sequence SHALL be one, except possibly when used in
-- contextAuditResult.

-- In PropertyParm, value is a SEQUENCE OF octet string. When sent
-- by an MGC the interpretation is as follows:
-- empty sequence means CHOOSE
-- one element sequence specifies value
-- If the sublist field is not selected, a longer sequence means
-- "choose one of the values" (i.e. value1 OR value2 OR ...)
-- If the sublist field is selected,
-- a sequence with more than one element encodes the value of a
-- list-valued property (i.e. value1 AND value2 AND ...).
-- The relation field may only be selected if the value sequence
-- has length 1. It indicates that the MG has to choose a value
-- for the property. E.g., x > 3 (using the greaterThan
-- value for relation) instructs the MG to choose any value larger
-- than 3 for property x.
-- The range field may only be selected if the value sequence
-- has length 2. It indicates that the MG has to choose a value
-- in the range between the first octet in the value sequence and
-- the trailing octet in the value sequence, including the
-- boundary values.
-- When sent by the MG, only responses to an AuditCapability request
-- may contain multiple values, a range, or a relation field.
