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

Good day all How do i set a connection between 2 asterisk servers via PRI In Bri I would set one to NT and TE How shoud the zapata.conf and zaptel.conf look And how should the cable be? All I got on the web was to set one to "pri_net"...this cant be all? And the cable > pin1 <--> pin4> pin2 <--> pin5> pin3 <--> pin6> pin4 <--> pin1> pin5 <-->

Hello, I have one UPS Infosec XP Pro 2500 RM and it works with windows sw RUPS2000. Now I want to install this UPS as virtual server on vmware ESXi vMA - (SUSE SLES 11SP2 linux). On this linux I have NUT 2.6.0 and I stopped now with configuration of genericups driver. Working cable (direct cable pin1-pin1 ... pin9-pin9) connection on Windows: PIN | PC | UPS

Hi! I have the chance to play with a couple of E400P cards, each installed in a IBM e330 XSeries servers (2 x 1GHz P-III CPU 2 Gb RAM, 36Gb SCSI HDD with RH8.0 2.4.18-smp kernel), and I'm trying to test/benchmark this e330/E400P combo generating calls thru /var/spool/asterisk/outgoing One e400P if doing the carrier work making calls and the other just receives the calls: Server#1

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:

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

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

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

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

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

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

30 says it's view only in the docs & I can't seem to change it, any other options? > Option 30 allows to set Module Shelf Address/ID.

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?

Hi, I have a Liebert Powersure Personal XT 700 and have followed the installation instructions from here http://www.networkupstools.org/doc/2.0.0/INSTALL.html. I'm pretty sure I've got the ups.conf, upsd.conf and ups.users correct. I have setup upsmon.conf as suggested in the installtion guide with the exception of FINALDELAY which I set to 0 when I found things weren't working
