Part 1 of the answer: If you are running this as a standard node, you need to specify an empty function table stanza so that nothing gets decoded. If you are running as a remote base node, then no DTMF functions will be decoded fromt he radio interface. Remote base nodes have .y on the end of them in the node table. This is how app_rpt knows which type of code to run. Part 2 of the answer: chan_usbradio causes DTMF digits to be printed on the console. As far as I know, there's no way to disable this without modifying the channel driver itself, but maybe Steve Henke knows something I don't. > > From: David McGough <kb4fxc(a)inttek.net> > Date: 2008/07/25 Fri AM 10:18:46 PDT > To: Asterisk Repeater Controler <app_rpt(a)lists.illiana.net> > Subject: [App_rpt] General config questions....try #2 > > > Hi Everyone, > > Since I haven't heard any feedback about this post, I guess the answer is > "no" to these questions??? ....If so, I think I'll have a go at > resolving them. > > Thanks! > > David KB4FXC > > > Original message: > > Now that I'm to the "beta" test phase, I've got some more questions that I > don't see answers to on the list--or have overlooked (if so, oops!). > > First, is there an easy way to disable DTMF decoding entirely for a > channel?

[App_rpt] USB hubs & USB audio

USB 2.0 hubs come in two flavors single- transaction translators (single-TT) and multi-transaction translators (multi-TT). Most USB audio devices are "full speed" devices (12 mbits/sec), not "high speed" devices (480 mbits/sec) so the USB hub must translate the data rate between the host and the device. The single-TT devices only have a single translator which is shared between all ports. A multi-TT hub has a translator per port. So in theory a milti-TT hub is what you should want for optimal bus usage. An additional complication is that the Linux kernel must be multi-TT hub aware to properly schedule things. I'm not current with Linux development, but I've read discussions in the past about improving the kernel's USB scheduler in this area. Here are a couple of links to info which may be useful: http://www.commsdesign.com/design_corner/showArticle.jhtml?articleID=165053… http://www.linux-usb.org/usb2.html 73's Skip WB6YMH

[App_rpt] General config questions....try #2

Hi Everyone, Since I haven't heard any feedback about this post, I guess the answer is "no" to these questions??? ....If so, I think I'll have a go at resolving them. Thanks! David KB4FXC Original message: Now that I'm to the "beta" test phase, I've got some more questions that I don't see answers to on the list--or have overlooked (if so, oops!). First, is there an easy way to disable DTMF decoding entirely for a channel? My HF node (on very staticy 75M) generates a fair number of spurious DTMF decodes. And, each time it thinks it hears a code, there is, as expected, a very short dropout of HF RX audio being passed to the UHF repeater side. I don't need DTMF decode at all for this node and would like to turn it off. Second, does anyone have (or know of) a simple utility to generate sound files for the CD ID, etc. Thanks! David KB4FXC

Tony, Try getting version 0.2, and see if it segfaults. Version 0.2 has been out for a while and 0.5 was just checked in today. Version 0.2 was what was originally written to work with rtpDir and may also be what Skip is using for the link box, all though I'm not sure about this. There has been recent talk of upgrading the protocol to send sequence numbers and DTMF packets. Version 0.5 looks like an attempt to do that. Steve R.

[App_rpt] Asterisk configuration for node with no locally connected RF and chan_rtpdir
by Tony Langdon, VK3JED 24 Jul '08

24 Jul '08

Just in the process of setting up an Asterisk node (AllStar 2199). At this time, the node has no local RF hardware (I am seriously considering adding a Kenwood remote base early next year), but I want to have a link to a remote system using chan_rtpdir, which will link to an established system. I have some sample configs, and the N9YTY notes, but those notes assume a local RF link. What I want to do is accept connections to AllStar node 2199 and have those linked to the rtpDir system. And from the other end, I want to be able to connect to other AllStar nodes. Anyone able to offer insight on this configuration? My current Asterisk installation is a hand compiled system (app_rpt is included). I didn't use EVB or ACID, because Asterisk is installed on an existing IRLP node, and I didn't want to wipe the system (for obvious reasons!). I may also look into configuring the system to link to the local IRLP node on demand, once I've got the hang of driving Asterisk. I played with Asterisk a long time ago and was able to set it up as a reasonable PBX with VoIP and a single analog line, but I'm a bit rusty now and I've never used app_rpt before. 73 de VK3JED http://vkradio.com
