LB ST
The Loopback State (LB ST) field indicates whether there are any remotely-initiated
loopbacks currently active on the HSU port. This field displays both latching and non-latching
loopbacks initiated from a remote device via in-band loop-up codes. In addition to none, the
six messages that can be displayed in that field are l-ocu, l-dsu and l-csu for latching
loopbacks, and ocu, dsu and csu for non-latching loopbacks. This is an information-only field;
it is not user-configurable.
