-- MEGACO TONES MIB ....
--
-- The MEGACO TONES MIB module consists of two tables
-- defined as megTonesToneTable and megTonesGroupTable.
-- Multiple tonesets are represented through the megTonesToneTable.
-- The tonesets share the data contained in the megTonesGroupTable
-- megTonesToneTable
-- The megTonesToneTable provides a list of the tones available on a
-- Media Gateway. The megTonesTable consists of five columns;
-- Column 1 (index): megTonesToneSetId - a number indicating a _
-- unique toneset; this number represents a
-- toneset (for a given market) available on a
-- Media Gateway.
-- Column 2 (index): megTonesToneId - a number indicating a unique
-- Tone Id value; this number represents a Tone Id
-- available on a Media Gateway.
-- Column 3: megTonesToneGroupId - a number indicating a unique Tone
-- Group Id that is associated with a megTonesToneId. This
-- number is also an index into the megTonesGroupTable.
-- Column 4: megTonesTone Name - this is a character string
-- indicating the Tone Name. (The Tone Name could be
-- represented by the text that gets passed in the
-- Signal Descriptor; i.e., the Package Id, Signal Id and
-- possible parameters.)
-- Column 5: megTonesToneTimeout - this value indicates when the
-- tone times out, expressed in milliseconds. This value
-- is used as the primary means to determine when the tone
-- times out; if the tone group duration(s) is greater
-- than the tone timeout value, the tone is finished
-- when the tone timeout occurs. A value of 0 signifies no
-- timeout.
-- Column 6: megTonesRowStatus - this is used to create new rows in
-- this table, modify existing rows, and to delete
-- existing rows.

-- megTonesGroupTable
-- The megTonesGroupTable provides the components that comprise
-- the various Group Ids.
-- The megTonesGroupTable is indexed by the megTonesToneGroupId
-- (from the megTonesTable) and the megTonesGroupIndex.
--
-- The columns of the megTonesGroupTable are as follows:
-- Column 1 (index): megTonesToneGroupId - a number indicating a
-- unique Tone Group Id value. This value is from
-- the megTonesToneTable.
-- Column 2 (index): megTonesGroupIndex - a number indicating the
-- component number of a tone group. If the tone
-- group contains only one component then this
-- value is 1; if the tone group contains multiple
-- components then this value starts at 1 and
-- increases by one sequentially for each
-- component.
-- Column 3: megTonesGroupRef- a number indicating an existing tone
-- group Id value.
-- Column 4: megTonesGroupLink - a number indicating the linkage, if
-- any, between components of the group as follows:
-- (1) SEQ: the next component follows sequentially in
-- time.
-- (2) MIX: the next component is to be mixed with the
-- current component and is simultaneous with it.
-- (3) MOD-AMP: the next component is amplitude modulated
-- with the current component. This is accomplished by
-- encoding information onto a carrier waveform by varying
-- the amplitude of the [sinusoidal] carrier.
-- Mathematically, this is expressed as:
-- y(t) = x(t)*cos(wc*t). In the context of the Tones
-- MIB, this refers to two signals (tones), one of which
-- is usually a simple sinusoid, whose sample values, at
-- any given instant in time, are multiplied together.
-- (4) MOD-FREQ: the next component is frequency modulated
-- with the current component. This is accomplished by
-- encoding information onto a carrier waveform by
-- varying the frequency of the [sinusoidal] carrier.
-- Mathematically, this is expressed as:
-- y(t) = ac*cos(x(t)). In the context of the Tones MIB,
-- this refers to a sinusoidal signal (tone) whose
-- instantaneous phase is given by a second signal.
-- (5) PCM: the current component indicated is Pulse Code
-- Modulation. In the context of the Tones MIB, it means
-- that incoming PCM (voice, for example) is passed
-- straight through, instead of having a signal (tone,
-- silence, etc.) applied.
-- Column 5: megTonesGroupFrequency - a number indicating the
-- frequency in hertz of a tone; The range is decimal 0 to
-- 4000.
Doyle et al. Standards Track _ Expires August 15, 2001 4
Tones MIB for Megaco/H.248 February 2001
-- Column 6: megTonesGroupLevel - a number indicating the amplitude
-- in dBmo of a tone; The range is decimal -128 to 0.
-- Column 7: megTonesGroupDuration - a number indicating the
-- duration expressed in milliseconds of a tone; The range
-- is decimal 0 to 32767. If the tone duration is less
-- than the timeout value specified for that tone, the
-- tone is finished when the duration is reached.
-- Column 8: megTonesGroupRepeatCount - a number indicating the
-- repeat count of a tone; the range is decimal 0 to
-- 32767, with a 0 value indicating infinite repeating.
-- Column 9: megTonesGroupRowStatus - This is used to create new
-- rows in this table, modify existing rows, and to delete
-- rows.
-- MEGACO TONES MIB RULES:
-- (1) A megTonesToneGroupId MUST NOT be deleted if it is referenced
-- by another existing megTonesToneGroupId.
-- (2) A megTonesToneGroupId value MUST NOT be the same value as a
-- megTonesGroupRef value for the same table row.
-- (3) A megTonesGroupRef value MUST be a previously defined
-- megTonesToneGroupId value.
-- (4) A megTonesGroupFrequency value REQUIRES a megTonesGroupLevel
-- value.
-- (5) The megTonesGroupRef field, the megTonesGroupFrequency field
-- and the megTonesGroupLink field with a value of PCM, MUST all
-- be mutually exclusive to each other.
-- (6) Every row MUST have a megTonesGroupLink equal to PCM, a
-- megTonesGroupRef OR megTonesGroupFrequency associated with
-- it.
-- (7) The megTonesGroupLink field is only valid for
-- megTonesGroupIndex equal to a value of 1.
-- (8) megTonesGroupRepeatCount is REQUIRED:
-- - if the megTonesGroupLink value is SEQ and (vice versa)
-- - AND if megTonesGroupIndex equal to a value of 1.
-- (9) Each row of a sequence MUST have a megTonesGroupDuration
-- unless:
-- - The row contains a megTonesGroupRef which points to a
-- megTonesToneGroupId which represents a sequence with
-- a finite megTonesGroupRepeatCount.
-- (10) megTonesGroupDuration is only valid within rows forming a
-- sequence.
-- (11) A megTonesToneId which references a megTonesToneGroupId not
-- based upon a finite repeat count sequence will have its
-- duration defined in the megTonesToneTimeout field.
-- (12) A megTonesToneId which references a megTonesToneGroupId that
-- directly or indirectly consists of a sequence group with a
-- finite repeat count SHALL have the duration defined by the
-- megTonesToneTimeout field or the duration of the sequence
-- (whichever is smaller).
-- (13) If a megTonesGroupLink of MIX, MOD-FREQ or MOD-AMP contains
-- one or more infinite duration components and a single finite
Doyle et al. Standards Track _ Expires August 15, 2001 5
Tones MIB for Megaco/H.248 February 2001
-- duration component, the resultant group MUST have a finite
-- duration equal to that of the finite duration component.
-- (14) If a megTonesGroupLink of MIX, MOD-FREQ or MOD-AMP contains
-- multiple components with different finite durations, those
-- components whose durations are less than the maximum finite
-- duration MUST be padded with silence to make them equal to
-- the maximum finite duration.

6. Example Tones MIB
The MEGACO TONES MIB module was modeled after the Megaco/H.248
Dynamic Tone Definition(dtd)package[4]. (The MIB can be used in
conjunction with dtd or it can be used independently.)
DefToneString = "(" DefToneElement ["*" RepeatCount ] ")"
[","/"+"/"X" DefToneString]
RepeatCount = %d1-32767 / %d0
NOTE: repeatcount of 0 indicates infinite repeating.
DefToneElement = ToneName ["," ToneDuration [ "," ToneAmplitude ]]
ToneName = (Package id, Tone id) / "#"FreqValue /
"&"AnnouncementParameterList
Package id = 1*VCHAR; Unique package identity string or value
Tone id = 1*VCHAR; Unique tone identity string or value
FreqValue = %d0-4000; in Hertz
AnnouncementParameterList = AnnouncementID ["," SubstitutionString]
AnnouncementID = 1*VCHAR; Unique identifier for an audio
announcement
SubstitutionString = """1*VCHAR"""; a string to be inserted into an
announcement.
ToneDuration = %d1-32767 / %d0 ; In Milliseconds
ToneAmplitude = "-"%d32-1 / %d0; In dBm0
Examples of some tone definitions are shown below:
cg/ct = ((((#480)+(#620)),400,-24),(sil,250))*0
cg/sit = (#950,330,-24), (#1400,330,-24),(#1800,330,-24)*1
xcg/spec = ((((#350,750,-7),(sil,750))*0)+(#440,0,-7))
Example of MEGACO TONES MIB populated with above tone definitions is
shown below:
NOTE: For this example 'cg/ct' (congestion tone) has a
megTonesToneId value of 1 for megTonesToneSetId 1 (North
American toneset,
Doyle et al. Standards Track _ Expires August 15, 2001 12
Tones MIB for Megaco/H.248 February 2001
'cg/sit' (special information tone) has a megTonesToneId value of 2
for megTonesToneSetId 1, and 'xcg/spec' has a megTonesToneId value
of 1 for megTonesToneSetId 2 (UK toneset).The values listed in the
timeout column were randomly chosen for this example.

7. Formal Syntax
The syntax used in the Tones MIB definition is from the SNMPv2-SMI
version of the SNMP message protocol and is described in[5][6][7].
8. Security Considerations
There are a number of management objects defined in this MIB
that have a MAX-ACCESS clause of read-write and/or read-create.
Such objects may be considered sensitive or vulnerable in some
network environments. The support for SET operations in a
non-secure environment without proper protection can have a
negative effect on network operations.
Doyle et al. Standards Track _ Expires August 15, 2001 13
Tones MIB for Megaco/H.248 February 2001
It is recommended that the implementers consider the security
features as provided by the SNMPv3 framework. Specifically, the
use of the User-based Security Model RFC 2574 [8] and the
View-based Access Control Model RFC 2575 [9] is recommended.
It is then a customer/user responsibility to ensure that the SNMP
entity giving access to an instance of this MIB, is properly
configured to give access to the objects only to those principals
(users) that have legitimate rights to indeed GET or SET
(change/create/delete) them.
