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” i n BC information element, call in A-law o n ly can be co nnected (call in µ-law is disconnected).5. This feature is activated when SETUP m es s ag e is sent.6. This feature is available only when user information Layer 1 protocol is A-law or µ-law (JT-V110/X30 orJT-X31, etc. cannot be converted).7. The user information Layer 1 protocol is not added to SETUP message if the received BC informationelement does not contain the Layer 1 protocol.8. Law conversion rule varies depending on the kind of outgoing trunk/terminal and incoming trunk/terminalin 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.
