PairGain
Engineering - Plant Series
11
UNFR*
Configures HiGain to operate in an unframed mode. This mode
disables the auto framing process and forces HiGain to
function as a transparent bit pipe.
HAIS
2LP*
Causes HiGain to transmit the AIS signal at both the HLU and
HRU T1 output ports when
both
of the HDSL loops are not in
sync (LOSW).
1LP
Cause the HiGain system to transmit the AIS signal at both the
HLU and HRU T1 output ports when either of the two HDSL
loops are not in sync (LOSW) or if a margin alarm occurs.
SAIS
ENA*
Causes the HRU-612 to transmit the AIS signal towards the
Network Interface (NI) when in NREM or Smart-Jack loopback.
DIS
Causes the List1 HRU-612 to transmit the signal from the
network towards the NI and the List 2 HRU-612 to open and
terminate its RCV NI port when an HRU NREM or Smart-Jack
loopback is executed. The AIS signal is off.
CONF
YES
Confirms that all twelve operating modes (listed above) are to
be updated to their current selections.
NO*
Prevents the most recently selected operating mode selections
from being updated. They remain as they were before the
system option settings mode was entered.
MARgin
Alrm Thrs
0 to 15 dB
The Margin Alarm Threshold can only be set via the RS-232
maintenance port with a terminal. It determines the minimum
allowable margin below which a minor alarm can occur.
4 dB*
(Default value)
DS0
BLK
The DS0 blocking option can only be set via the RS-232
maintenance port with a terminal. The 4-character HLU-611
List 3 front panel LED readout only displays the status of the
blocking option. BLK indicates at least one channel is blocked.
NONE*
NONE indicates no channels are blocked.
ALM
DIS*
Opens the relay alarm contacts, if closed, and prevents another
relay alarm closure from occurring.
ENA
Enables activation of the minor alarm relay when a minor alarm
condition occurs.
*Indicates HLU-611 factory (default) settings.
