DTE Address Structure 196
DATAPAC internal calls can use either the national address or the international
address with the DATAPAC DNIC (3020). All international addresses,
however, must be preceded by the digit 1 (this international prefix is a
DATAPAC option and is not passed between networks).
Note
All international calls must select Priority Traffic Class. For more
information, see “An Example of Non-CCITT Facilities” in this appendix.
For more information contact your DATAPAC representative, or access the
DATAPAC Information Service (its DTE Address is 3020 92100086).
Example: Packet SwitchStream (British Telecom)
When connected to Packet SwitchStream (PSS), the full X.121 address
(DNIC+ National Address number) must be used for inland as well as
international calls.
Note
Your PC operates as a PSS packet mode DTE. Therefore, do not prefix
an international address with the escape digit 9.
