104 Part F: Configuring Channels MB8100-00-00-806 © TEL 2003Line levels are expressed as dBm for the balanced line input and Vpp (voltspeak-to-peak) for the unbalanced line input.Power SavingIn the Add or Edit Channel Profile dialog box, the Power Savingtab lets you specify how power saving will be applied when the basestation is running on battery power. A graph shows the meaning of Rx cyclingand Tx keyup time. The three areas below the graph define the parametersfor Normal, Sleep, and Deep Sleep modes. Sleep and Deep Sleep modes requirea Power Saving Modes license.Normal Defines how the base station operates normally. Normal mode can involve adegree of power saving.Sleep The Sleep check box enables Sleep mode. The related group box defines howthe base station operates in Sleep mode. A base station enters Sleep mode whenthe receiver has been idle for the length of time specified in the Sleep mode’sStart after box.Deep Sleep The Deep Sleep check box enables Deep Sleep mode. The related group boxdefines how the base station operates in Deep Sleep mode. A base station inSleep mode enters Deep Sleep mode when the receiver has been idle for thelength of time specified in the Deep Sleep mode’s Start after box.Rx cycling Rx cycling is the length of time in milliseconds that the receiver is switched offfor. Usually, the receiver runs continuously, but this may not be necessary.Power saving is effected by switching off the receiver, switching it back on tocheck if there is a valid signal, switching it off again, and so on. Rx cycling istherefore the maximum gap between periods of reception. It is slightly shorterthan the maximum detection time, by an amount that depends on systemconditions.
