similar to: Tellabs 2572 Configuration Advice?

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

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

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 T1 cable: http://www.arcelect.com/RJ48C_and_RJ48S_8_position_jack_.htm which looks like it

Hello, I have been researching Echo Can's for a while now, and wanted to post this out to the list to solicit feedback (and if my assumptions are correct, hopefully help others out)... If anyone out there knows anything about wiring up an Echo Can, and my outline below is incorrect, please let the me/list know.. I have posted the Documents I received from Tellabs at:

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? Not to say I

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? TIA, -- Troy Settle Pulaski Networks http://www.psknet.com 540.994.4254 ~ 866.477.5638 Pulaski Chamber 2002 Small Business Of The Year

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

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?

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

Many of you are familiar with how lousy Festival sounds. AT&T has a product, NaturalVoices, that sounds much better. There are male & female voice fonts for US/UK/Indian English, French, Spanish, and German. I am considering offering a linux-based text-to-speech engine based on the NaturalVoices runtime. An asterisk module would also be provided, making it easy to add natural sounding

We are trying to install a Tellabs echo canceler on our T-1/PRI and having no luck. We can't get the lines out of AIS/RED/BLUE alarm when we put in the echocan. We are looking for a consultant (near New Orleans) to assist us in installing this device. Contact John DeMajo <jdemajo@stirlingprop.com> at +1-504-858-7689 --Eric -- Always do right. This will gratify some people and

Using TDM400's here and I have tried everything to cure the echo. I have used the Milliwatt test from the telco and from asterisk to tune RX/TX gain via a patched ztmonitor. What happens is I experience midcall echo. I turned on aggressive_suppressor and it seems to do great. The problem happens with misc. noise around the office will cause it to mute the other end of a phone call while

I'm having issues with echo. My setup is Polycom IP501 phones connected to an Adit 600 via T100P. 13 Lines going to the Adit. All echo so far is on the local side (Employees hears own voice, but only on some calls). Watching the channel with ztmonitor, I notice that TXGAIN is pegged out most of the time. RXGAIN is anywhere between 45 and 60%. Is it safe to assume that playing around

Greetings, Using Xen 3.1 and Fedora 7, is it possible to export the serial interface such that I can access external devices on COM1 or COM2? I am uncertain if PCI pass-thru is needed or if there''s nothing to configure for this to work in a fully virtualized Linux guest. Any help would be greatly appreciated.

Anybody using hardware echo cancelers a PRI at a time ? What did you use ? How much did they cost ? Where'd you get em. Tell us about them ! Alan

Hi, I've had some decent luck with the mark3 echo canceller from the zaptel driver, echos on about 20% of the calls, people I've called say I sound great now, but our side hears echos. I was wondering if there was any way to tweak the current software cancelers into using more CPU (and hopefully doing a better job, close to a hardware canceler), I only have 10 lines, and a single call
