Table 5-1 Reference: Output Layer 1 Protocol - NEC NEAX 2400 IPX Programming Manual

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
