LOOPBACKS
SMJK
Smartjack Loopback
Loopback at HRU towards network initiated by 2 in 5 in-band loopback
code or out-of-band ESF data link code. See Figure 4.
NREM
Network Remote
Loopback
Loopback at HRU (remote) towards network initiated from CO (network)
by intelligent line repeater #1 code, HRU front panel push-button or
maintenance terminal. See Figure 4.
NLOC
Network Local
Loopback
Loopback at HLU (local) towards network initiated from CO (network) by
intelligent office repeater code or by pressing both the MODE & SEL HLU
front panel pushbuttons. See Figure 4.
HDU1
Network Doubler 1
Loopback
Loopback at Doubler 1 towards network initiated from CO (network) by
intelligent office repeater #1 code or from Loopback Mode menu or by
pressing both the MODE & SEL HLU front panel pushbuttons.
HDU2
Network Doubler 2
Loopback
Loopback at Doubler 2 towards network initiated from CO (network) by
intelligent repeater # 20 code or from Loopback Mode menu or by pressing
both the MODE & SEL HLU front panel pushbuttons.
CLOC
Customer Local
Loopback
Loopback at HRU (local) towards CI initiated from CPE (customer) by
intelligent line repeater #1 code. See Figure 4.
CREM
Customer Remote
Loopback
Loopback at HLU (remote) towards customer initiated from CPE
(customer) by intelligent office repeater code. See Figure 4.
CDU1
Customer Doubler 1
Loopback
Loopback a Doubler 1 towards CI initiated from CPE (customer) by
intelligent line repeater #2 code . See Figure 4
CDU2
Customer Doubler 1
Loopback
Loopback a Doubler 1 towards CI initiated from CPE (customer) by
intelligent line repeater #2 code . See Figure 4
ARM
Armed
HiGain detected the intelligent repeater loopback (2 in 5) arming code.
TLOS
Transmit Loss Of
Signal loopback
HRU is in a logic loopback state caused by a loss of its T1 input from the
NI, if enabled via SAIS option.
