LOOPBACKS:
SMJK
Smart-Jack Loopback
The loopback at HRU-412 (remote) toward network (see Figure
6) initiated by either the (2 in 5) in-band loopback code or the
out-of-band ESF data link loopback code.
NREM
Network Remote Loopback
The loopback at HRU-412 (remote) toward network (see Figure
6) initiated from CO (network) by either the Intelligent Line
Repeater (ILR) number 2 code, the HLU-319 front panel Manual
Loopback push buttons, the HRU-412 front panel push button,
or the maintenance terminal.
NLOC
Network Local Loopback
The loopback at HLU-319, List 2D (local) toward network (see
Figure 6) initiated from CO (network) by either the Intelligent
Office Repeater (IOR) code, the HLU-319 front panel Manual
Loopback push buttons, or the maintenance terminal.
CLOC
Customer Local Loopback
The loopback at HRU-412 (local) toward CI (see Figure 6)
initiated from CPE (customer) by either the ILR number 2 code,
the HLU-319 front panel Manual Loopback push buttons, or the
maintenance terminal.
CREM
Customer Remote Loopback
The loopback at HLU-319, List 2D (remote) toward customer
(see Figure 6) initiated from CPE (customer) by either the IOR
code, the HLU-319 front panel Manual Loopback push buttons,
or the maintenance terminal.
ARM
Armed
The HiGain system detected the IR loopback (2 in 5) arming
code.
TLOS
Transmit Loss of Signal
(Loopback)
HRU-412 is in a logic loopback state, caused by a loss of its
DS1 input from the CI when ENAbled at the HRU-412, List 6 or
List 7, via its TLOS switch option.
