We were discussing of realization of FAX-services under X.400
This is a file where the use of FAX of in SWITCH is described.
Most comercial services using X.400 offer also Telex and FAX as
bodytype. (I have list of 20 KB, but in respect, that his list
is feed into the USENET I don't dare to post it)

Subject: X.400 -> FAX/TELEX Gateway
Dear SWITCHmail user,
the Swiss PTT has an operational X.400 -> FAX/TELEX gateway service.
With SWITCHmail your are able to use it following the addressing rules
below:
1) Addressing of FAX-subscribers
-----------------------------
X.400 address: C=CH
ADMD=arcom
X121=9+(country-code without 00 + fax-number
incl. area-code)
RFC822 address: /X121=9+(country-code + fax-number)/@arcom.ch
2) Addressing of TELEX-subscribers
-------------------------------
X.400 address: C=CH
ADMD=arcom
X121=8+(country-code without 00 + fax-number
incl. area-code)
RFC822 address: /X121=8+(country-code + fax-number)/@arcom.ch
3) Examples
--------
Example for a fax-subscriber in Switzerland:
C=CH;ADMD=arcom;X121=94131627035;
.....------ fax-number
...-- area-code for Berne
.-- country-code for Switzerland
- code for fax-delivery
/X121=94131627035/@arcom.ch
Example for a fax-delivery to Washington in USA:
C=CH;ADMD=arcom;X121=912024290514;
......------ fax-number
...-- area-code for Washington
.-- country-code for USA
- code for fax-delivery
/X121=912024290514/@arcom.ch
Example for a TELEX-subscriber in Switzerland:
C=CH;ADMD=arcom;X121=845941030
...------ TELEX-number
.-- country-code for Switzerland
- code for TELEX-delivery
/X121=845941030/@arcom.ch
4) Important notice:
-----------------
- Country codes as well as area-codes (city-codes) are needed without
leading '0's
- arCom 400 fax cannot receive fax-messages. Due to this,
please give instructions to the receiver of your messages how
to get back to you.
- maximum line-length is 80 characters (letter-wrapping!)
- supported alphabet is IA5, similar to US ASCII.
- The FAX gateway generates a front page reflecting the header lines of
the email message. This information is often useless to detect who
was the sender of that message and who is the receiver.
Please indicate in the body of your message very clearly the intended
recipient and identify yourself as the sender similar to a standard
postal letter head.
- Users on the RFC822 part of the SWITCHmail network (using domain addresses)
could have problems reaching the FAX or TELEX gateway by the address
indicated above. In case of problems contact your local postmaster.
Many gateway software is not able to handle it correctly.
(-> Use X.400 instead :-))
A mail from a user within a SWITCH member site through the FAX gateway
is billed by SWITCH as if the recipient would be a non SWICHmail member.
(However Swiss PTT charges SWITCH differently according to the
destination of the FAX.)
We start with that policy and monitor the use of the gateway service.
Hoping you enjoy the additional functionality,

Urs, I was surprised to see "X121=" as the prefix for fax and telex numbers. I had thought that X121 addresses were for X.25 services and had a distinct numbering plan from the E.164 telephone numbers used today for fax. Have I just totally forgotten something about the definition of X121? Vint
/G=Peter/S=Varlien/OU=TRONDHEIM/O=ND ServiceTeam/PRMD=NORSK DATA/@noprmd.telemax.no (06/04/91)
Vint, X.121 is for data network addresses (i.e. both X.21 and X.25). In addition, X.121 defines escape digits 0,8,9 for Telephone, Telex and Telephone (again) numbers. (Two escape digits for telephone for administrations who need to handle digtal and analog systems separately.) (It is possible that this escape digit business was added to X.121 to support Teletex, which in some countries uses the Telephone network for transport, whereas in other countries use the public data network. It also allowed interworking with Telex. As you can see, it comes in handy for addressing Fax and Telex from X.400, too.) +---------------------------+------------------------------------------+ !
