Script para alineación de CPE Mikrotik

El siguiente es un script que se utiliza para alinear un CPE 433/411 de Mikrotik. Tiene algunas características como:

  • Reconocimiento de 9 señales
  • Reconoce 3 estados: searching,associated, disable/other
  • Usa 4 de los 5 led que tiene el rb 433/411

Script Code:

#
# Mikrotik RB411/433 «Lights and Sound» alignment script
# written by Mark Shumate Feb 2009
#
# NOTE: This script may work on other platforms, I
# don’t have anything but RB411/433 here in front of
# me. The beeps will probably work on practically any
# wireless AP type Routerboard, but maybe the script
# would have to be edited? Dunno if it complains when
# you reference LEDs that don’t exist…
#
# This script recognizes 9 different «signal levels»
# and 3 assoc. statuses (connected, searching, other)
# Currently, «signal levels» indicate the SNR/margin
# measurement. Higher signal-to-noise measurements
# correspond to higher levels. So level 8 would be
# the best, below 1 would be the worst. The better
# the signal-to-noise, the more LEDs you get, and
# the faster the beeps get. Only 4 LEDs are used,
# (the 5th being left alone, for NAND access ind.)
# with intermediate signal levels resulting in a
# combination of solid and flashing LEDs, shown
# here:
#
# >= Level 8 : 4 solid (100ms beeps)
# >= Level 7 : 3 solid, 4th flashing (300ms beeps)
# >= Level 6 : 3 solid (500ms beep cycle)
# >= Level 5 : 2 solid, 3rd flashing (700ms beeps)
# >= Level 4 : 2 solid (900ms beeps)
# >= Level 3 : 1 solid, 2nd flashing (1100ms beeps)
# >= Level 2 : 1 solid (1300ms beeps)
# >= Level 1 : 1 flashing (1500ms beeps)
# <  Level 1 : no LEDs, beeps only (1700ms beeps)
#
# The user-LED (green LED above the blue power LED)
# is used to display the association status. If the
# wireless interface is associated, the user-LED is
# solid. If the wireless interface is actively
# searching, but not yet associated, the user-LED is
# blinking twice a second, with a pause while a
# rising trill of 3 beeps is played. If the wireless
# interface is neither associated, nor searching
# (like disabled, or something weird) then the light
# will flicker rapidly every 2 seconds, and a
# falling trill of 2 beeps is played.

# Finally, the script plays startup (rising) and
# shutdown (falling) tones.

# For reference, the delay times associated with the
# different signal levels are shown here:
#:local lnsdelaytime 100ms;  <—signals at/above lvl 8
#:local lnsdelaytime 300ms;  <—signals between 7 and 8
#:local lnsdelaytime 500ms;  <—signals between 6 and 7
#:local lnsdelaytime 700ms;  <—signals between 5 and 6
#:local lnsdelaytime 900ms:  <—signals between 4 and 5
#:local lnsdelaytime 1100ms; <—signals between 3 and 4
#:local lnsdelaytime 1300ms; <—signals between 2 and 3
#:local lnsdelaytime 1500ms; <—signals between 1 and 2
#:local lnsdelaytime 1750ms; <—signals below lvl 1
#:local lnsdelaytime 2000ms; <—signal not available
