TTL Type
Specifies the type of terminating test line (TTL) selected for testing trunks. The 
TTL type determines what ATMS tests can be completed and thus which 
threshold values need to be administered.
The following table explains the differences between types of terminating test 
lines:
The far-end switch containing the TTL may be any of the following:
nSystem 85 R2 switch, equipped...
