connection may be used to change the parameters of the unit, check and clear 
alarms or collect measurement and quality statistics. 
 
Furthermore, the modem is at the Node M/Cs request to alert the operator when 
there is an alarm. The modem may be over-the-air (wireless) or public switched 
telephone network (PSTN). It is possible to install the wireless modem or the PSTN

modem be used, the operator should ensure that the settings are changed prior to 
leaving the site.

acknowledged and collected in the OMC.
