Hi,

I’m having some questions related to echo cancellation configuration
on a Digium board enabled systems (B410P, TE420, TE420B, ….) for
cases when a hardware ech canceller is present or not.

I read in TEXXX manual that when setting echocancel=yes in
chan_dahdi.conf on a VPMOCT64-equiped system, 128ms hardware echo
cancellation was enabled.

1. I’m correct thinking that it is then impossible to switch from
hardware to software echo can without removing the VPMOCT64 module
itself ?
2. Does the same also apply to HA8 and its VPMOCT032 module ?
3. Are the only options for OSLEC configuration the echocancel=128 or
echocancel=256 values in chan_dahdi.conf ?
4. How could be compared user experience with oslec/256, mg2/256,
mg2/1024 on a HA8 without hardware module ? Which would you recommend
?

Regards

Hi,

I have a new Digium TE205P 2-span E1 card I just installed on a server.

As soon as I boot the machine, the card’s leds flash red (ports 1 and 2) – even when in the BIOS.

That’s not good, right?

I don’t have another machine to test at the moment but would like to know what to expect.
I have several single-span E1 cards and when the machine boots, their leds are off until the kernel module is loaded.

What could be the problem with my TE205P? Could it be damaged (brand new) or is it more likely to be a PCI-BIOS issue?

Thanks,

Vieri

hello list

i have one question how to check if the app_mysql module is compiled and
loaded in my system if not how can i do in order to install it and load it
i use asterisk 1.4

thanks and regards

Version 2.1 of app-espeak and app-flite modules just got released.

Changes include voice selection for flite, support for 16kHz file
playback in asterisk 1.6.x, use of libsamplerate for faster resampling,
better error handling and cleaner code.

You can get them here:

Asterisk espeak module:

Asterisk flite module:

Greetings-

On occasion, I’m seeing the following in syslog on some systems using analog cards with FXS modules:

[ 1664.861183] Power alarm on module 1, resetting!

These are typically cleared by restarting asterisk/dahdi, or power cycling the system. However, I’m wondering if anyone can explain what condition exactly causes this. My best guesses:

-Too high current draw on port (shorted pair)
-Not enough current supplying card/module (bad power supply)
-Voltage introduced to FXS port (FXS port connected to FXO or POTS line for example)

Thanks!
