Selecting V.120 for Germany National ISDN

(1TR6)

1TR6 data connections are achieved by setting the Service

Indicator to 7 (Daten_bertragung 64Kbps) and the Additional

Information octet is used to select B channel protocols. Since

there is no pre-defined code for asynchronous V.120, TA128 uses

the synchronous V.120 code to fill in the additional information

octet. This approach might not work all the time.
