37.4 Integral LMU/RLM
The lamp monitoring facility provided by the Integral TC12 OTU firmware (integral
LMU/RLM) is not used on an ST900 since the ST900 includes its own lamp monitor
(see section 38). This means that only the OTU handset commands (which start with
the letter âGâ) are re-directed to the integral OTU since all the LMU handset
commands (which start with the letter âKâ) are handled by the controller itself.
