experience with analog channel banks in E1 land
hi,
we are currently planning are large site which will migrate from an old
siemens hicom pbx to asterisk.
it will be a slow migration, the asterisk server will be inserted
between the telco E1 and the hicom. new phones will be sip ones.
the customer has several fax machines and analog phones (some of them
have to be explosion-proof). around 50 analog ports in total are needed.

dhclient doing DISCOVER with bad IP checksum - bge
Sorry for the cross-post, but this could be either lists problem.
I have 2 boxes running 7-STABLE as of 20081130, both i386 SMP. One is
running ISC DHCPD 3.0.x from recent ports, and the other dhclient from
make world.
The server is refusing to answer the DISCOVER request, as it thinks the
IP checksum is wrong, which tcpdump also confirms. Other DHCP clients
are working fine on this network,

Hi,
I'd like to change 3 TDM400p with one TDM2400p to avoid echo (my
intention is to use a TDM2400P echo cancel module). It TDM2400p working
good with asterisk 1.2.1? Or I need to install a new asterisk version?

TDM400P/FXS in a HP DL380 G5
The HP DL380 G5 (like many rack servers) has no AMP Mate-n-Lok connector
available to attach to a card that needs more power than the PCI bus can
provide, like the TDM400P when FXS modules are used. HP has confirmed that
there is no part they sell to give you such a connector, and Digium says
their business edition folks got it to work, but only by doing nasty
warranty-voiding things to the

How to determine the power draw on TDM2400P?
For example, how much power would a server with 3 of the TDM2400P fully
loaded cards draw?
We're trying to figure out what APC power we should have to achieve
approx 30 minutes back-up time.
Would appreciate any learnings or methods on calculating the power draw
and determining the appropriate back-up device.
Thank you.
Melisa.

TDM2400P problems
I am having issues with a TDM2400P. It appears when the ZAP channel dials
out, it randomly chops the first digit off of the number. I have tried
relaxdtmf=yes, turning up and down the txgain, turned off and on the echo
cancellation, generated new zaptel (with updated spinlock.h)...
I am at a loss. Can someone please offer some help?
Thanks.

TDM2400p bad sound quality
Hi list,
I have this problem:
when someone is making a call, with asterisk and a TDM2400P connected to 8
fxo lines, the sound is good, but if three, for people are calling at the
same time the sound got worse and worse.
Using other voip cards the sound is much better even with all user calling
at the same time.
What can be, the problem?

TDM2400P dial tone is not present on phones, but the phone ring with incoming calls
Hi,
I have a problem with TDM2400P card. The card is detected ok, I can make a call but only with pulse dialing (not tone dialing) without hear sounds from the headset. When I receive a call, I can to establish a communication, but without hear sounds from the headset. When I dial any phone key, I can hear dtmf tone.

TDM2400P driver change
Hello,
Thank you for your support of Digium and Asterisk.
Yesterday, we identified a problem with the driver for the TDM2400P
card when used with FXO port modules. The X400M was producing (and
expecting) the audio signal at an abnormally high level, which
negatively impacted the performance of the echo cancelers, both hardware
and software. It also resulted in unusual audio artifacts when the

tdm2400p: fax detection not working
Hi,
I cannot make my TDM2400P (with Echo Canceller module) detect faxes. I
tried with a TDM400P and it worked at 80% (20% of faxes were lost). My

TDM2400P Problem
Hi All,
I have the problem with TDM2414E card (16FXO & 4 FXS with echo

button but nothing happens even the busy tone). There is no activity in
the asterisk CLI. It just prints

TDM2400p and HW echo canceller
Do the zaptel drivers need to be told >NOT< to use the software echo
canceller when using a TDM2400p card with hardware echo canceller, or
does the driver figure this out by itself?
Thanks,
Andrew

Additional Wildcard TDM2400P Setup
Hello,
We've purchased a 2nd Wildcard TDM2400P for our asterisk server. I've looked
around but I can't find documentation on how to properly setup 2 or more
telephony boards in asterisk. In particular, I want to ensure that the boards
are assigned the same device channels on boot (for example, if you have two
NICs in a Linux box and you want to make sure one card is always eth0

TDM2400P with echo canceller not working
Hi,
I have a box with Debian Sarge, Asterisk 1.2.1 (and zaptel 1.2.1) and a
TDM2400P with echo canceller. I installed the card but no echo
cancellation is being made...seems like the echo canceller module does
not work, infact the software cancellation is working.
My zapata.conf has echocancel = 128 and echocancelwhenbridged = yes but
no echotraining parameter which gives a warning.

RE : TDM2400p bad sound quality
Hi Francois,
Thank you for your interest.
I tried the card alone so I don't think is an IRQ problem (anyway is there a
way to be sure?)
To be sincere, in all systems I saw (even working ones) there is an IRQ
balance failed where Linux boots.
The system is new, I tried different processors (P4 and Celeron) with SMP
kernel and without.
The card has the echo module, could not be

Hi. I am using Digium TDM2400PFXO with Asterisk1.6. When call sets in the

answer the call when the phone is picked up. Its charging the clients.
Please let me know how can I cover this ? Thanks in advance.

TDM2400P
We just bougth a tdm2400p with all the modules for FXO, but we are
having some troubles with the card, cause it aparently is stripping
some digits from the dialed number, we tested the same server with a
tdm400 and everything worked as expected.
We?ve already added "w" before the dialed number with no results, is
there any way to solve, is it a bug

Channelbanks
Ok, the Zhone sucks and the Adtran 750/850 seems to be a little too
expensive.
Can anyone recommend a decent channelbank that won't break the bank?
