		+	The link activity timer may be used to reset a link configuration back to a default configuration if a user changes how the node is linked. This helps in situations where the user forgets to reset the system to the default values, or drives out of range.
		+
		+	The activity timer is armed when the link state is changed by a local DTMF function. The activity timer is zeroed whenever a signal is heard on the receiver, and the activity macro is executed when the timer reaches the lnkacttime value.
		+
		+	The Link Activity timer is supported in app_rpt.c version 0.182 or later.
		+
		+	=== COP functions ===
		+	There are three cop functions associated with the Link Activity Timer:
		+	{\| class="wikitable"
		+	!COP Function
		+	!Description
		+	!Telemetry Response
		+	\|-
		+	\|45
		+	\|Link Activity timer enable
		+	\|LATENA
		+	\|-
		+	\|46
		+	\|Link Activity timer disable
		+	\|LATDIS
		+	\|-
		+	\|47
		+	\|Reset "Link Config Changed" Flag
		+	\|none
		+	\|}
		+	Functions 45 and 46 enable and disable the activity timer function. These can be used to enable or disable the activity timer.
		+
		+	Function 47 is used to reset the "Link Config Changed" Flag. This flag is set whenever a user connects or disconnects a link. This is useful for implementing macros where you want to change the link state without arming the activity timer.
		+
		+	=== Key/Value Pairs ===
		+	All of the key value pairs noted below are placed in the node stanza. There are four key value pairs related to the link activity timer.
		+
		+	==== lnkactenable= ====
		+	Set to 1 to enable the link activity timer at initialization, or 0 to leave it disabled. The default is 0.
		+
		+	'''Note:''' If the activity timer is disabled in rpt.conf, it can still be enabled with the COP command.
		+
		+	==== lnkacttime= ====
		+	This sets the amount of time to wait before executing the inactivity macro. Set to a value between 180 and 2000000 seconds.
		+
		+	==== lnkactmacro= ====
		+	This is the function to execute when the activity timer expires. This can either be a function or another macro defined in the [macros] stanza.
		+
		+	==== lnkacttimerwarn= ====
		+	For a 30 second warning message, set this to the path of a ulaw or pcm sound file to play locally when there is 30 seconds left on the activity timer.
		+
		+	'''Note:''' Do not include the extension name of the sound file.
		+
		+	If no path is specified, the default path will be /var/lib/asterisk/sounds.
		+
		+	=== Example ===
		+	lnkactenable=1 ; Enable link activity timer
		+	lnkacttime=900 ; 15 minute link activity timer
		+	lnkactmacro=*52 ; Use macro 2 in the [macros] stanza for link activity timer
		+	lnkacttimerwarn=30sectillsitenorm ; Sound file for 30 second warning message located in /var/lib/asterisk/sounds
