Process ISDN Data Link Down
This field allows a system to determine whether or not the BRI trunk port processes an ISDN
Data Link Down message. When this flag is set to Yes and a BRI trunk port receives an ISDN
Data Link Down message, then a BRI trunk port drops all calls and attempts to bring the ISDN
data link up. When this flag is set to No and a BRI trunk port receives an ISDN data link down
message, then the BRI trunk ignores the ISDN data link down. Some Central Offices (local
exchanges in Europe) will release its TEI after a B-channel trunk has been idle for some time.
This causes an ISDN data link down message to be sent from the CO (local exchange) to the
switch. In this case, if the switch processes the ISDN data link down message, it may drop the
call on the other B-channel trunk on that port. The default value of this field is to ignore the
ISDN data link down message.
Retry ARS Call IF Call Rejected
See page 6-133.
