5.4 FXS Port Setting
FXS (Foreign Exchange Station) is the interface on a VoIP device for connecting directly to telephones,
fax machines, or similar device and supplies ring, voltage, and dial tone.
5.4.1 FXS Port Setting for All Line
This IAD supports 7 types of Caller ID scheme as below:
¾ DTMF (Dual Tone Multi-Frequency): DTMF is an example of a multi-frequency shift keying
(MFSK) system. Today DTMF is used for most call setup to the telephone exchange, at least in
developed regions of the world, and trunk signaling is now done out of band using the SS7 signaling
system.
¾ FSK Bellcore: The Bellcore standard is used in United States, Australia, China, Hong Kong and
Singapore. It uses the 1200 baud Bell 202 tone modulation and the first bit of data is transferred
after receiving the first ring tone.
¾ FSK ETSI: The European Telecommunications -1 and -2, and ES 200 778-1 and -2, the latter
replacing ETS 300 778-1 & -2) allows 3 physical transport layers (Bellcore, BT and CCA)
combined with 2 data formats (MDMF & SDMF), plus the DTMF system and a no-ring mode for
meter-reading and the like. It's more of a recognition that the different types exist than an attempt to
define a single "standard".
¾ Japan CLIP (Calling Line Identification Presentation): It is published by Japan ETSI. The Caller
ID information is received from the service provider before the first ring. Set the ring event in the
application to occur on or after the first ring. The ring event indicates reception of the CLIP Caller
ID information from the CO.
¾ Japan JCLIP (Japanese Calling Line Identity Presentation): It is published by Japan NTT.
¾ BT: British Telecom developed their own standard, which wakes up the display with a line reversal,
then sends the data as CCITT V23 modem tones in a format similar to MDMF. It is used by BT,
wireless networks like the late Ionica, and some cable companies.
¾ Brazil DTMF: DTMF used in Brazil.
