MF Tone Generation and Detection Packages
Status of this Memo
This document is an Internet-Draft and is in full conformance with
all provisions of Section 10 of RFC2026 [1].
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF), its areas, and its working groups. Note that
other groups may also distribute working documents as Internet-
Drafts. Internet-Drafts are draft documents valid for a maximum of
six months and may be updated, replaced, or obsoleted by other
documents at any time. It is inappropriate to use Internet- Drafts
as reference material or to cite them other than as "work in
progress."

1. Abstract
This document provides multi-frequency (MF) tone generation and MF
tone detection packages for Megaco/H.248.
2. Conventions used in this document
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in
this document are to be interpreted as described in RFC-2119 [2].
3. Multi-Frequency Tone Generation Package
3.1 Package
PackageID: mfg (0x003d)
Description: This package defines the basic MF tones as signals and
extends the allowed values of parameter t1 of playtone in tonegen.
Version: 1
Extends: tonegen version 1
3.2 Properties
None.

MF Tone Generation and Detection Packages Mar 2002
3.3 Events
None.
3.4 Signals
Signal Name: MF signal code 0
SignalID: mf0 (0x0050)
Description: Generate MF signal code 0. The characteristics of the
MF signal code, including frequencies and durations, are provisioned
on the MG.
Signal Type: Brief
Duration: Provisioned
Additional Parameters: None
Additional Values:
mf0 (0x0050) is defined as a toneid for playtone. (0x0050 was chosen
arbitrarily).
The other MF signal codes are specified in exactly the same way. A
table with all signal names and signal Ids is included below. Note
that each mf signal code is defined as both a signal and a toneid,
thus extending the basic tone generation package. Also note that mf
signal Ids are different from the names used in a digit map.
Signal Name Signal ID/
tone id
mf signal code 0 mf0 (0x0050)
mf signal code 1 mf1 (0x0051)
mf signal code 2 mf2 (0x0052)
mf signal code 3 mf3 (0x0053)
mf signal code 4 mf4 (0x0054)
mf signal code 5 mf5 (0x0055)
mf signal code 6 mf6 (0x0056)
mf signal code 7 mf7 (0x0057)
mf signal code 8 mf8 (0x0058)
mf signal code 9 mf9 (0x0059)
mf signal code KP mfa (0x005a)
mf signal code KP' mfb (0x005b)
mf signal code KP'' mfc (0x005c)
mf signal code KP''' mfd (0x005d)
mf signal code ST mfe (0x005e)
mf signal code ST' mff (0x005f)
mf signal code ST'' mfg (0x0060)
mf signal code ST''' mfh (0x0061)
3.5 Statistics
None.

3.6 Procedures
None.
4. Multi-Frequency Tone Detection Package
4.1 Package
PackageID: mfd (0x003e)
Description: This package defines the events required for basic MF
tone detection. This package extends the possible values of tone id
in the "start tone detected", "end tone detected" and "long tone
detected" events.
Version: 1
Extends: tonedet version 1
4.2 Properties
None.
4.3 Events
Event Name: MF signal code 0
EventID: mf0 (0x0050)
Description: Detect MF signal code 0. The characteristics of the MF
signal code, including frequencies and durations, are provisioned on
the MG.
EventsDescriptor Parameters: None.
ObservedEventsDescriptor Parameters: None.
Additional Values:
The other MF signal codes are specified in exactly the same way. A
table with all event names, event Ids and digit map symbols is
included below. The event Ids are defined with same names as the
signal Ids in package mfg. The additional tone id values are the
same tone id values defined in package mfg.
Event Name Event ID/ Digit Map
tone id Symbol
mf signal code 0 mf0 (0x0050) "0"
mf signal code 1 mf1 (0x0051) "1"
mf signal code 2 mf2 (0x0052) "2"
mf signal code 3 mf3 (0x0053) "3"
mf signal code 4 mf4 (0x0054) "4"
mf signal code 5 mf5 (0x0055) "5"
mf signal code 6 mf6 (0x0056) "6"
mf signal code 7 mf7 (0x0057) "7"
mf signal code 8 mf8 (0x0058) "8"
mf signal code 9 mf9 (0x0059) "9"
mf signal code KP mfa (0x005a) "A" or "a"

mf signal code ST''' mfh (0x0061) "H" or "h"
Event Name: Digit Map Completion Event
EventID: ce

EventsDescriptor Parameters: Digit map processing is activated only
if a digit map parameter is present, specifying a digit map by name
or by value.
ObservedEventsDescriptor Parameters:
Parameter Name: Digit String
ParameterID: ds (0x0001)
Description: The collected address string which matched part or
all of an alternative event sequence specified in the digit
map.
Type: string of digit map symbols returned as a quoted string.
Possible values: a sequence of characters "0" through "9", "A"
through "H", and the long duration modifier "Z", and the
interdigit threshold timer "T", "S" and "L".
Parameter Name: Termination Method

Description: indicates the reason for the generation of the
address event.
Type: enumeration
Possible values:
"UM" (0x0001) Unambiguous match
"PM" (0x0002) Partial match, completion of timer expiry
or unmatched event
"FM" (0x0003) Full match, completion by timer expiry or
unmatched event
