Rpt.conf

Rpt.conf is where the majority of the node configuration occurs. Important node settings such as the node CW and voice ID, touchtone commands and timers are set. The default DIAL rpt.conf is well commented (see rpt.conf on GitHub).

Node Number Stanza

The node number stanza is the first stanza in rpt.conf.

[1999]    ; Replace with your assigned node number

The node number stanza contains the following key/value pairs.

althangtime=

This controls the length of the repeater hang time when the alternate hang timer is selected with a control operator function. It is specified in milliseconds.

Sample:

althangtime=4000   ; 4 seconds

beaconing=

When set to 1 will send the repeater ID at the idtime interval regardless of whether there was repeater activity or not. This feature appears to be required in the UK, but is probably illegal in the US.

Sample:

beaconing=1   ;Set to 1 to beacon. Defaults to 0

callerid=

This setting allows the autopatch on the node to be identified with a specific caller ID. The default setting is as follows

callerid="Repeater" <0000000000>

Note: The value in quotes is the name of the autopatch caller, and the numbers in angle brackets are the originating telephone number to use.

context=

This setting directs the autopatch for the node to use a specific context in extensions.conf for outgoing autopatch calls. The default is to specify a context name of radio.

context=radio

controlstates=

This setting defines the name of the variable named control state stanza. Control states are an optional feature which allows groups of control operator commands to be executed all at once. To use control states, define an entry in your node stanzas to point to a dedicated control state stanza like this:

controlstates = controlstates   ; points to control state stanza

[controlstates]
0 = rptena,lnkena,apena,totena,ufena,noicd  ; Normal operation                                  
1 = rptena,lnkena,apdis,totdis,ufena,noice  ; Net and news operation                                             
2 = rptena,lnkdis,apdis,totena,ufdis,noice  ; Repeater only operation

The control state stanza (below) describes these mnemonics.

duplex=

The duplex key/value pairs sets the duplex mode for desired radio operation. Duplex mode 2 is the default if none specified.

Duplex Mode	Description
0	Half duplex with no telemetry tones or hang time. Special Case: Full duplex if linktolink is set to yes. This mode is preferred when interfacing with an external multiport repeater controller. Comment out idrecording and idtalkover to suppress IDs.
1	Half duplex with telemetry tones and hang time. Does not repeat audio. This mode is preferred when interfacing a simplex node.
2	Full Duplex with telemetry tones and hang time. This mode is preferred when interfacing a repeater.
3	Full Duplex with telemetry tones and hang time, but no repeated audio.
4	Full Duplex with telemetry tones and hang time. Repeated audio only when the autopatch is down.

Sample:

duplex = 0     ; 0 = Half duplex with no telemetry tones or hang time.

endchar=

This setting allows the end character used by some control functions to be changed. By default this is a #. The endchar value must not be the same as the funcchar default or overridden value.

erxgain=

Echolink receive gain adjustment in +/- db-volts. Used to balance Echolink recieve audio on an app_rpt node.

erxgain = -3

See Echolink How to

etxgain=

Echolink transmit gain adjustment in +/- db-volts. Used to balance Echolink transmit audio on an app_rpt node.

etxgain = 3

See Echolink How to

funcchar=

This setting can be used to change the default function starting character of * to something else. Please note that the new value chosen must not be the same as the default or overridden value for endchar=.

hangtime=

This controls the length of the repeater hang time. It is specified in milliseconds.

Sample:

hangtime = 1000   ;Set hang time for 1 second

holdofftelem=

This node stanza configuration key forces all telemetry to be held off until a local user on the receiver or a remote user over a link unkeys. There is one exception to this behavior: When an ID needs to be sent and there is activity coming from a linked node.

Sample:

holdofftelem = 1   ;Set to 1 to hold off. Default is 0

idrecording=

The identifier message is stored in the node stanza using the idrecording key. It can be changed to a different call sign by changing the value to something different. The value can be either a morse code identification string prefixed with |i, or the name of a sound file containing a voice identification message. When using a sound file, the default path for the sound file is /var/lib/asterisk/sounds.

Sample:

idrecording = |iwa6zft/r   ; Morse Code ID

or

idrecording = /var/lib/asterisk/sounds/myid   ; Voice ID

Note: ID recording files must have extension gsm,ulaw,pcm, or wav. The extension is left off when it is defined as the example shows above. File extensions are used by Asterisk to determine how to decode the file. All ID recording files should be sampled at 8KHz. See Recording audio files

idtalkover=

The ID talkover message is stored in the node stanza using the idtalkover setting. The purpose of idtalkover is to specify an alternate ID to use when the ID must be sent over the top of a user transmission, This can be a shorter voice ID or an ID in morse code. The value can be either a morse code identification string prefixed with |i, or the name of a sound file containing a voice identification message. When using a sound file, the default path for the sound file is /var/lib/asterisk/sounds. Example usages are as follows:

Sample:

idtalkover = |iwa6zft/r   ; Morse Code ID

or

idtalkover = /var/lib/asterisk/sounds/myid   ; Voice ID

Note: ID recording files must have extension gsm,ulaw,pcm, or wav. The extension is left off when it is defined as the example shows above. File extensions are used by Asterisk to determine how to decode the file. All ID recording files should be sampled at 8KHz. See Recording audio files

inxlat=

The inxlat setting allows complete remapping of the funcchar and endchar digits to different digits or digit sequences. inxlat acts on the digits received by the radio receiver on the node.

Format: inxlat = funchars,endchars,passchars,dialtone

where:

• funcchars is the digit or digit sequence to replace funcchar
• endchars is the digit or digit sequence to replace endchar
• passchars are the digits to pass through (can be used to block certain digits)
• dialtone is optional. Set to Y for dial tone on successful funcchars.

Sample:

inxlat = #56,#57,0123456789ABCD ; string xlat from radio port to sys

linkmongain=

Link Monitor Gain adjusts the audio level of monitored nodes when a signal from another node or the local receiver is received. If linkmongain is set to a negative number the monitored audio will decrease by the set amount in db. If linkmongain set to a positive number monitored audio will increase by the set amount in db. The value of linkmongain is in db. The default value is 0 db.

Sample:

linkmongain = -20   ; reduce link volume 20dB

linktolink=

When operating in duplex mode 0, this forces the radio interface to operate in full duplex mode, but keeps all the other duplex mode 0 semantics. This is used when a radio interface is connected to a multiport analog repeater controller. The linktolink= key can take two values: yes or no.

Sample:

linktolink = yes   ; set to yes to enable. Default is no.

linkunkeyct=

The linkunkeyct setting selects the courtesy tone to send when a connected remote node unkeys. The default is no courtesy tone when a remote node unkeys.

Sample:

linkunkeyct = ct8  ; use courtesy tone 8

nounkeyct=

The nounkeyct node stanza key completely disables the courtesy tone. This is useful for eliminating TX time in applications using simplex uplinks to repeaters on the repeater pair itself. This practice is strongly discouraged.

Sample:

nounkeyct = yes  ; :(

politeid=

The politeid setting specified the number of milliseconds prior to the end of the id cycle where the controller will attempt to play the ID in the tail when a user unkeys. If the controller does not get a chance to send the ID in the tail, the ID will be played over the top of the user transmission. Optional, default 30000.

Sample:

politeid = 30000   ; 30 seconds

propagate_dtmf=

Takes either yes or no. When set to yes, DTMF will be regenerated from out-of-band signalling or from from the receiver dtmf decoder whenever a function start character is NOT detected and command decoding has not begun. When set to no, no tones will be regenerated. The default for this setting is no. This setting is meant to be used in conjunction with linktolink, inxlat, and outxlat when interfacing a radio port to a multiport analog repeater controller on an RF-linked system.

Sample:

propagate_dtmf = no

Note: There is a separate setting propagate_phonedtmf for use by dial-in (phone and dphone) users.

remotect=

The remotect setting allows the selection of the remote linked courtesy tone so that the users can tell there is a remote base connected locally.

Sample:

remotect = ct3   ; use courtesy tone 3

rxburstfreq=

If rx tone burst operation is desired, specify the frequency in hertz of the desired tone burst. Setting to 0 (or not specifying) indicates no tone burst operation.

Sample:

rxburstfreq = 1000

rxburstthreshold=

In rx toneburst mode, specifies the minimum signal to noise ratio in db that qualifies a valid tone. Defaults to 16 (db).

rxbursttime=

For rx toneburst operation, specifies minimum amount of time that tone needs to be valid for recognition (in milliseconds). Defaults to 250.

rxchannel=

The rxchannel key/value pair selects the radio interface. There must be one (and only one) rxchannel per node. The selections are:

Value	Description
dahdi/pseudo	No radio, used for hubs
SimpleUSB/usb_1999	SimpleUSB (limited DSP)
Radio/usb_1999	USBRadio (full DSP)
voter/1990	RTCM
Pi/1	Raspberry Pi PiTA
Dahdi/1	PCI Quad card
Beagle/1	BeagleBoard
USRP/127.0.0.1:34001:32001	GNU Radio interface USRP

Sample:

rxchannel = dahdi/pseudo     ; No radio (hub)

Note: This is selecting what is known as (in Asterisk terminology) the channel driver.

sleeptime=

This sets the inactivity period in seconds for no signal on the repeater receiver before the system goes to sleep.

Sample:

sleeptime = 300   ; go to sleep after 5 mins of no activity

startup_macro=

The startup_macro is executed once on system startup. Each node can have one startup macro defined in its node stanza.

Sample:

startup_macro = *31000*31001*31002   ; Connect to 1000, 1001 and 1002 at startup

tailmessagelist=

The tailmessagelist setting allows a comma separated list of audio files to be specified for the tail message function. The tail messages will rotate from one to the next until the end of the list is reached at which point the first message in the list will be selected. If no absolute path name is specified, the directory var/lib/asterisk/sounds will be searched for the sound file. The file extension should be omitted.

Sample:

tailmessagelist = welcome,clubmeeting,wx   ; rotate 3 tail messages

Note: ID recording files must have extension gsm,ulaw,pcm, or wav. The extension is left off when it is defined as the example shows above. File extensions are used by Asterisk to determine how to decode the file. All ID recording files should be sampled at 8KHz. See Recording audio files

tailmessagetime=

This sets the amount of time in milliseconds between tail messages. Tail Messages are played when a user unkeys on the repeater input at the point where the hang timer expires after the courtesy tone is sent.

Sample:

tailmessagetime = 900000   ; 15 minutes between tail messages

tailsquashedtime=

If a tail message is "squashed" by a user keying up over the top of it, a separate time value can be loaded to make the tail message be retried at a shorter time interval than the standard tailmessagetime= setting. The tailsquashedtime= setting takes a value in milliseconds.

Sample:

tailsquashedtime = 300000   ; 5 minutes

totime=

This defines the time out timer interval. The value is in milliseconds.

Sample:

totime = 180000   ;  3 minutes

unlinkedct=

The unlinkedct setting selects the courtesy tone to be used when the system has no remote nodes connected and is operating as a standalone repeater.

Sample:

unlinkedct = ct2   ; use courtesy tone 2

Functions Stanza

Function stanzas control access to DTMF commands that a user can issue from various control points in app_rpt. There can be separate function stanzas defined for radio interfaces, and dial-in access. Nodes on the same Asterisk/app_rpt server can have separate (or same) function stanzas. A function stanza key/value pair has the following format:

dtmfcommand=functionclass,[functionmethod],[parameters] Where:

• dtmfcommand is a DTMF digit sequence minus the start character (usually *)
• functionclass is a string which defines what class of command (see the next page)
• functionmethod defines the optional method number to use in the function class.
• functionoptions are one or more optional comma separated parameters which further define a command.

Sample:

989=cop,4   ; generate test tone.

This stanza is named by the functions=, link_functions=, or the phone_functions= key/value pairs in the node stanza.

Status Commands

Status commands provide general information about the node.

Status	Status Function
1	Force ID (global)
2	Give Time of Day (global)
3	Give software Version (global)
4	Give GPS location info
5	Speak the last (dtmf) user
11	Force ID (local only)
12	Give Time of Day (local only)

COP Commands

COP (control operator) commands are privileged commands. Node admins may provide some of these to their user community based on personal preference. COP commands within rpt.conf take the general format of key/value pairs. This COP 7 example would set touchtone *99 to enable the timeout timer.

99 = cop,7

Some COP commands can take multiple parameters. For example this COP 48 would send #3#607 on command.

900=cop,48,#,3,#,6,0,7
