[Asterisk-Users] Squeaking / chirping on ZAP Digium TDM400P

I've got an asterisk server 1.07 with a Digium TMD400P (2fxo;2fxs).  I
have it configured to answer an incoming line and transfer to one of the
2 fxs's and it works.

I have noticed that on incoming calls I get intermittent squeaks and
chirps on the line that I don't get if I plug the incoming line to a
PSTN.  I'm the only conversation on this hardware and it is a 2.2Ghz P4
with 512Meg RAM.

Any ideas on what or how to look for this problem?

Thanks,

-Peter

Could be an interrupt conflict. Do a "cat 
/proc/interrupts" on a linux command line and see if the 
TDM is sharing an interrupt with another device.

[Asterisk-Users] Squeaking / chirping on ZAP Digium TDM400P

Here is my printout below.  It looks to me like it is sharing with USB.
I don't seem to have a way in my bios to turn off USB though and nothing
is plugged into it.  Could that be a problem?  Also, are the other
things mentioned all part of Asterisk?

Thanks,  -Peter

[Asterisk-Users] Squeaking / chirping on ZAP Digium TDM400P

It's an HP Pavillion (Pentium 2Ghz)  

[root@seventythirdstreet init.d]# uname -a
Linux seventythirdstreet 2.4.21-27.0.1.EL #1 Fri Dec 24 03:18:37 GMT
2004 i686 athlon i386 GNU/Linux

Also, do you know how to make the hostname change permenant?  Everytime
I reboot, it goes back to the default.

Thanks,  -Peter

Peter,

	Wow.  That's pretty bad.  Try disabling some "legacy" devices
that you 
may not need: serial ports, parallel ports, etc.  The BIOS really should

have an option to disable USB.  While you are disabling that other stuff

check again.  Freeing up this stuff should give you more free
interrupts.

	You should not load ztdummy when you have real hardware for
timing. 
wctdm is good enough.  So disable the loading of ztdummy.  And, just for

kicks, what kernel are you running (uname -a), and what kind of machine 
is this (motherboard/chipset if possible)?

Thanks,  I think the file I wanted was
/etc/sysconfig/network

I'm using the CentOS which is part of the asterisk@home build.

host name permanent
either:
	hostname >> /etc/HOSTNAME
or
	echo "<hostname>" >> /etc/HOSTNAME
