32\section adsi_page_sec_1 What does it do?
33Although ADSI has a specific meaning in some places, the term is used here to indicate
34any form of Analogue Display Service Interface, which includes caller ID, SMS, and others.
35
36The ADSI module provides for the transmission and reception of ADSI messages
37in various formats. Currently, the supported formats are:
38
39 - Bellcore/Telcordia GR-30 CORE CLASS (Custom Local Area Signaling Services) standard
40 (North America, Australia, China, Taiwan, and Hong Kong).
41
42 - ETSI ETS 300 648, ETS 300 659-1 CLIP (Calling Line Identity Presentation) FSK standard
43 (France, Germany, Norway, Italy, Spain, South Africa, Turkey, and the UK).
44
45 - ETSI Caller-ID support for the UK, British Telecom SIN227 and SIN242.
46
47 - ETSI ETS 300 648, ETS 300 659-1 CLIP (Calling Line Identity Presentation) DTMF standard
48 variant 1 (Belgium, Brazil, Denmark, Finland, Iceland, India, Netherlands, Saudi Arabia,
49 Sweden and Uruguay).
50
51 - ETSI ETS 300 648, ETS 300 659-1 CLIP (Calling Line Identity Presentation) DTMF standard
52 variant 2 (Denmark and Holland).
53
54 - ETSI ETS 300 648, ETS 300 659-1 CLIP (Calling Line Identity Presentation) DTMF standard
55 variant 3.
56
57 - ETSI ETS 300 648, ETS 300 659-1 CLIP (Calling Line Identity Presentation) DTMF standard
58 variant 4. (Taiwan and Kuwait).
59
60 - ETSI Caller-ID support in UK (British Telecom), British Telecomm SIN227, SIN242.
61
62 - Nippon Telegraph & Telephone Corporation JCLIP (Japanese Calling Line Identity
63 Presentation) standard.
64
65 - Telecommunications Authority of Singapore ACLIP (Analog Calling Line Identity
66 Presentation) standard.
67
68 - TDD (Telecommunications Device for the Deaf).

70\section adsi_page_sec_2 How does it work?
71
72\section adsi_page_sec_2a The Bellcore CLASS specification
73Most FSK based CLI formats are similar to the US CLASS one, which is as follows:
74
75The alert tone for CLI during a call is at least 100ms of silence, then
762130Hz + 2750Hz for 88ms to 110ms. When CLI is presented at ringing time,
77this tone is not sent. In the US, CLI is usually sent between the first
78two rings. This silence period is long in the US, so the message fits easily.
79In other places, where the standard ring tone has much smaller silences,
80a line voltage reversal is used to wake up a power saving receiver, then the
81message is sent, then the phone begins to ring.
82
83The message is sent using a Bell 202 FSK modem. The data rate is 1200 bits
84per second. The message protocol uses 8-bit data words (bytes), each bounded
85by a start bit and a stop bit.
86
87Channel Carrier Message Message Data Checksum
88Seizure Signal Type Length Word(s) Word
89Signal Word Word
90
91\section adsi_page_sec_2a1 CHANNEL SEIZURE SIGNAL
92The channel seizure is 30 continuous bytes of 55h (01010101), including
93the start and stop bits (i.e. 300 bits of alternations in total).
94This provides a detectable alternating function to the CPE (i.e. the
95modem data pump).
96
97\section adsi_page_sec_2a2 CARRIER SIGNAL
98The carrier signal consists of 180 bits of 1s. This may be reduced to 80
99bits of 1s for caller ID on call waiting.
100
101\section adsi_page_sec_2a3 MESSAGE TYPE WORD
102Various message types are defined. The commonest ones for the US CLASS
103standard are:
104
105 - Type 0x04 (SDMF) - single data message. Simple caller ID (CND)
106 - Type 0x80 (MDMF) - multiple data message. A more flexible caller ID,
107 with extra information.
108
109Other messages support message waiting, for voice mail, and other display features.
110
111\section adsi_page_sec_2a4 MESSAGE LENGTH WORD
112The message length word specifies the total number of data words
113to follow.
114
115\section adsi_page_sec_2a5 DATA WORDS
116The data words contain the actual message.
117
118\section adsi_page_sec_2a6 CHECKSUM WORD
119The Checksum Word contains the twos complement of the modulo 256
120sum of the other words in the data message (i.e., message type,
121message length, and data words). The receiving equipment may
122calculate the modulo 256 sum of the received words and add this
123sum to the received checksum word. A result of zero generally
124indicates that the message was correctly received. Message
125retransmission is not supported. The sumcheck word should be followed
126by a minimum of two stop bits.
127
128\section adsi_page_sec_2b The ETSI CLIP specification
129The ETSI CLIP specification uses similar messages to the Bellcore specification.
130They are not, however, identical. First, ETSI use the V.23 modem standard, rather
131than Bell 202. Second, different fields, and different message types are available.
132
133The wake up indication generally differs from the Bellcore specification, to
134accomodate differences in European ring cadences.
135
136\section adsi_page_sec_2c The ETSI caller ID by DTMF specification
137CLI by DTMF is usually sent in a very simple way. The exchange does not give
138any prior warning (no reversal, or ring) to wake up the receiver. It just
139sends a string of DTMF digits. Around the world several variants of this
140basic scheme are used.
141
142One variant of the digit string is used in Belgium, Brazil, Denmark, Finland, Iceland,
143India, Netherlands, Saudi Arabia, Sweden and Uruguay:
144
145 - A<caller's phone number>D<redirected number>B<special information>C
146
147Each of these fields may be omitted. The following special information codes are defined
148
149 - "00" indicates the calling party number is not available.
150 - "10" indicates that the presentation of the calling party number is restricted.
151
152A second variant of the digit string is one of the following:
153
154 - A<caller's phone number>#
155 - D1# Number not available because the caller has restricted it.
156 - D2# Number not available because the call is international.
157 - D3# Number not available due to technical reasons.
158
159A third variant of the digit string is used in Taiwan and Kuwait:
160
161 - D<caller's phone number>C
162
163A forth variant of the digit string is used in Denmark and Holland:
164
165 - <caller's phone number>#
166
167There is no distinctive start marker in this format.
168
169\section adsi_page_sec_2d The Japanese specification from NTT
170
171The Japanese caller ID specification is considerably different from any of the others. It
172uses V.23 modem signals, but the message structure is uniqeue. Also, the message is delivered
173while off hook. This results in a sequence
174
175 - The phone line rings
176 - CPE answers and waits for the caller ID message
177 - CPE hangs up on receipt of the caller ID message
178 - The phone line rings a second time
179 - The CPE answers a second time, connecting the called party with the caller.
180
181Timeouts are, obviously, required to ensure this system behaves well when the caller ID message
182or the second ring are missing.
