572CHAPTER 37: ISDN CONFIGURATION COMMANDS

Parameter check-index: Called number or subaddress checking index, which is in the range of 1 to 3.

called-party-number: Called number, a string of 1 to 20 digits.

subaddress: Subaddress, which is a string of digits and/or case-insensitive English letters and is 1 to 20 characters in length.

Description Use the isdn check-called-numbercommand to configure the called number or subaddress that the system should verify when receiving a digital call.

Use the undo isdn check-called-numbercommand to remove the configuration.

By default, the system does not check the called number or subaddress carried by incoming digital calls.

This command is used for setting the examined item when a digital call is received. If a subaddress is specified, the system will deny an incoming digital call if the calling party sends a wrong subaddress or does not send at all.

Example # Check whether the called number carried by incoming digital calls is 66668888 on the interface BRI 1/0.

Parameter date-time: Time to be set when ISDN call checking is launched, in the format of HH:MM.

Description Use the isdn check-timecommand to enable ISDN call checking and set the time when ISDN call checking is launched.

Use the undo isdn check-timecommand to restore the default.

By default, ISDN call checking is disabled.

With ISDN call checking enabled, the system checks to see whether or not the call control blocks of the CC module and the Q.931 module are synchronized by checking all the ISDN call records on the set time point every day. The ISDN calls whose call control blocks are not synchronized are released.
