Description 
Operators Allowed 
004:LINK-FAIL-ABN-FIB 
This threshold type allows the user to check the 
number of times MTP level 2 took the link out of 
service due to an unexpected forward indicator 
bit. 
•  Equal to <value1> 
•  Not equal to <value1> 
•  Less than <value1> 
•  Less than or equal to <value1> 
•  Greater than <value1> 
•  Greater than or equal to <value1> 
•  Greater than <value1> and less than 
<value2>  
•  Less than <value1> or greater than 
<value2> 
005:LINK-FAIL-SIOS-RCV 
This threshold type allows the user to check the 
number of times MTP level 2 took the link out of 
service because it received a Status Indication 
Out-of-Service link status signal unit from the 
remote end of the link. 
•  Equal to <value1> 
•  Not equal to <value1> 
•  Less than <value1> 
•  Less than or equal to <value1> 
•  Greater than <value1> 
•  Greater than or equal to <value1> 
•  Greater than <value1> and less than 
<value2>  
•  Less than <value1> or greater than 
<value2> 
006:LINK-FAIL-EXC-DELAY-
ACK 
This threshold type allows the user to check the 
number of times the link was taken out of service 
because MTP level 2 did not receive an ACK for 
an MSU before timer T7 expired. 
•  Equal to <value1> 
•  Not equal to <value1> 
•  Less than <value1> 
•  Less than or equal to <value1> 
•  Greater than <value1> 
•  Greater than or equal to <value1> 
•  Greater than <value1> and less than 
<value2>  
•  Less than <value1> or greater than 
<value2> 
007:LINK-FAIL-EXC-CONG-
DUR 
This threshold type allows the user to check the 
number of times MTP level 2 took the link out of 
service because the remote end was still in a 
congested state when timer T6 expired. 
•  Equal to <value1> 
•  Not equal to <value1> 
•  Less than <value1> 
•  Less than or equal to <value1> 
•  Greater than <value1> 
•  Greater than or equal to <value1> 
•  Greater than <value1> and less than 
<value2>  
•  Less than <value1> or greater than 
<value2> 
008:LINK-FAIL-SUERM-
EXCEED 
This threshold type allows the user to check the 
number of times MTP level 2 took the link out of 
service because the signal unit error rate threshold 
was exceeded. 
•  Equal to <value1> 
•  Not equal to <value1> 
•  Less than <value1> 
•  Less than or equal to <value1> 
•  Greater than <value1> 
•  Greater than or equal to <value1> 
•  Greater than <value1> and less than 
<value2>  
•  Less than <value1> or greater than 
<value2> 
009:LINK-FAIL-IDLE-TIMER-
EXPIRE 
This threshold type allows the user to check the 
number of times MTP level 2 took the link out of 
service because it received no signal units before 
the idle link timer expired. 
•  Equal to <value1> 
•  Not equal to <value1> 
•  Less than <value1> 
•  Less than or equal to <value1> 
•  Greater than <value1> 
•  Greater than or equal to <value1> 
•  Greater than <value1> and less than 
<value2>  
•  Less than <value1> or greater than 
<value2>
