RST-100 INSTALLATION AND CONFIGURATION MANUAL

SLIC off
How long in ms the loop is powered down between off-hook checks. The longer this value the
more power saving, at the expense of a longer off-hook detect time.
SLIC holdup
Once the phone has been hung up after a call, wait this amount of time in seconds before
going back to power saving mode. This reduces the annoyance of the slow off-hook detection
when the user is making multiple calls. Reducing this time will not have much affect on battery
life overall.
Start V
The on-hook economy only engages after the input (battery) voltage drops below this value. If
the batteries are under charge most likely the economy mode is not required.
Warning!:
This value is set in 10ths of volts. ie. 100 is 10.0 Volts.
Stop V
After engaging the on-hook economy only disengages when the input (battery) voltage rises
above this value. Note that Stop V should always be higher than Start V to allow some
hysteresis.
Warning!:
This value is set in 10ths of volts. ie. 100 is 10.0 Volts.
Fault V
Log an error in the error log if the input (battery) voltage drops below this value. This is handy
for remote monitoring of remote battery powered systems to check they are not consistently
over-flattening the batteries potentially causing permanent damage. Set this value just above
the threshold below which the batteries would be damaged if discharged further.
Warning!:
This value is set in 10ths of volts. ie. 100 is 10.0 Volts.
Wake hour list
A string that specifies how often the LBT is to wake up the LBT when in No-Incoming power
save mode. The string format is similar to unix cron style.
It is a comma separated list of absolute UTC hours (times) to wake up the LBT. In addition, a *
followed by a digit N will wake up the LBT every N hours. If no digit N follows a
,
1 (every
hour) is assumed. Wake up rate (*) and absolute hours can be mixed.
Eg. *6, 13, 14 will wake up the LBT at 00,06,12,13,14,18 hours UTC.
If the RST hasn’t registered before going to sleep it will not have a valid UTC time so will not
wake up at times in the wake hour list.
Serial port activity or lifting the receiver will also re-activate or keep activated the LBT for the
wake time. When making an outgoing call you must wait for a dial tone to replace the no-
network tone (which indicates the LBT is now registered and ready to place the call).
The wake hour list can be set remotely (assuming an initial wake time is long enough to
receive incoming command SMS) to temporarily wake up more often a unit of interest or even
turn off this power save mode. Battery charge will of course be sacrificed.
