Tellabs and a PRI
Another question,
Is anybody using the Tellabs 2572 EC with a PRI. When we moved from our
analog lines to a PRI, I thought it would be simple stuff moving the EC
to the PRI. Changed signaling, made sure that channel 24 wasn't being
ECd and everything came up. But, I was getting complaints of random echo
on the PRI. Local echo. Also, we weren?t able to do any kind of modem
dial-outs (Adit

Tellabs 2572 EC Photos here.
Hello Dan,
Have a look at this link:
http://www.adcomcorp.com/asterisk/tellabs
I got those pictures up there, may be of help. In essence, 1 pair is
either a tx pair or an rx pair.
If I recall, Orange and Green should be one side, and blue brown should
be the other side.
I tried to upload them to the wiki (even 40% size) but they didn't show
up for some reason...
Files are large on the

Software E.C. Along with Tellabs
Since putting my Tellabs EC into place around 2 weeks ago, the echo
problem has almost been eliminated. Reports of some very faint echo,
but everybody is happy.
My question is, if I were to also turn on the Asterisk Software EC,
would this remove any residual echo that may make it past the Tellabs
Hardware EC.
Thanks,
Doug

If anyone out there knows anything about wiring up an Echo Can, and my
outline below is incorrect, please let the me/list know..

Tellabs 2572 Configuration Advice?
Can anyone share any advice / documentation on how to configure a Tellabs
2572 T1 echo canceller? I connected one between a T100P and an Adtran
TA750 FXO/FXS channelbank, but when echo cancellation is active I get
a LOT of snap-crackle-pop (and other problems) on the line.
The 2572 has a bunch of configuration options and they're impossible to
guess without documentation, which I cannot find

Tellabs echo can, can someone wire mine up for $?
Hello All,
I have a tellabs 2572 EC, and I was wondering if anyone with experience
can wire this up for me...
I have the proper tools and info, but not the time. It's easier to send
it out and get it done. I know kb1_kanobe originally started the wiki
thread, and rather than risking the card, would it be possible for me to
send it out to him, have him do it, and send it back?

Hardwiring a Tellabs echo canceller - help req
Hi All, Greg has been a huge help getting me going with this tellabs echo
can, but I'm still having some problems getting it to work... I suspect I
wired it up incorrectly, so I thought I'd see if anyone can point me in the
right direction. Digium tech support pointed me to this doc for a standard

Tellabs Echo Canceller
I am getting ready to experiment with the Tellabs 2752 echo canceller. I have a 255D shelf (and power supply), but am struggling a little on connecting the echo canceller to a PRI.
The shelf has 4 25-pair amphenol connectors. The two on the line side are marked "Receive In" and "Send Out". The 2 connectors on the drop side are marked "Send In" and "Receive

two tellabs 2572 echo board in a 253c mounting assembly?
Anyone gotten two of the 2572 echo canceller cards to work in a 253c mounting assembly? I can get one to work, but when I install two, one always fails. I've tried all my cards solo in the enclosure, on each side, and they all work properly when only 1 is installed, however, when I install two, one of them will come up, but the other always fails. Anyone know what might be causing this?
