CHAPTER 6 NDA-24305

Revision 1.0
Q-SIG/ISDN INTERNATIONAL GATEWAY SWITCHING
4. When the protocol is selected as AUSTRALIA in the route class data (assigned in ARTD, CDN65: INT)
and the coding standard is “00” in BC information element, call in A-law only can be connected (call in µ-
law is disconnected).
5. This feature is activated when SETUP message is sent.
6. This feature is available only when user information Layer 1 protocol is A-law or µ-law (JT-V110/X30 or
JT-X31, etc. cannot be converted).
7. The user information Layer 1 protocol is not added to SETUP message if the received BC information
element does not contain the Layer 1 protocol.
8. Law conversion rule varies depending on the kind of outgoing trunk/terminal and incoming trunk/terminal
in the office where the law conversion is activated. See Table 5-1.
Note 1:
Follows the system data assignment (SYS1, INDEX64, b0: 0/1=µ-law/A-law).
Note 2:
Non-conversion except when the ISDN terminal interface specification is assigned as N-ISDN1 by the
system data assignment (In this case, the output Layer 1 protocol is fixed as µ-law).
Note 3:
Varies depending on the terminal type.
