All of the HRU loopbacks towards the
network (NREM & SMJK) are metallic/logic
(AIS/ENA) or metallic only (AIS/DIS) except for
the TLOS initiated loopback, which is logic only.
The SMJK identifying label indicates that the
loopback was initiated by the 3 in 5 in band
command. NREM is used to indicate that the
metallic loopback was initiated by other than the
3 in 5 command (3 in 7, 16 bit addressable
repeater commands or front panel push-button).
