SPAN IS NOT FULL 

SHDSL 

The distance between adjacent repeaters is too 

long. You can identify the problematic segment 

by checking the Port Status screen. In the 
Number of Repeaters line, it displays the last 

repeater identified by ASMi-52. This means that 

the distance between the last detected repeater 
and the next repeater exceeds its maximum 

range.
