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.

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

Use the undo isdn check-called-number command 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.

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

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

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

Use the undo isdn check-time command 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.
