Stef asks:

"While I am in here -- Does anyone have any idea as to how much use
will be made of the Terminal Identifier and the User Agent Numeric
Indentifier attributes of the ORADdress?"

User Agent Numeric Identifier I won't comment. Terminal Identifier
appears from my reading of X.400/88 and X.402/88 intended to be paired with
X.121 address when accessing "Telematic terminals" (i.e. Telex and
Teletex) through an access unit. Telex answerbacks and Teletex terminal
identifiers are specifically used as examples. I haven't actually seen this
implemented, our ADMD here in Norway is currently using DDAs to address
Telex subscribers through their AU. If anyone knows of a TTX AU, perhaps
they can confirm that 2421-520147=NDTRDCTS is the same as
X121=2421520147;T-ID=NDTRDCTS;C=?;ADMD=?
Likewise, 55101 NDTRD N (Telex) should be X121=85655101;T-ID=NDTRDN;
C=... (Country/ADMD in my examples as appropriate for addressing the AU
in question. The TLX/TTX numbers are to test systems here, until my boss
decides not to pay for them any longer...)
Teletex hasn't been much of a success, I believe Germany has this largest
installed base with about 10000 terminals. (The Norwegian TTX service
will be shut down next year, it had about 200 subscribers before the PTT
decided to throw in the towel.) Telex, however, is VERY wide spread. In
the less developed parts of the world I've heard it often works better
then the Telephone network (and thereby also better than Fax...).

Conclusions: 1) Terminal-ID is only useful if there are AU's around that
use it. 2) The user needn't be bothered with it unless he (she) has
entered an X.121 address already.
