YET Another echo issue PRI CARD Any help accepted :-)
Good Day all,
I have a Fractional PRI connected to my Asterisk Box via a T100P
card.
When I initiate a call out to phone number 123-8888 the call
sounds great no echo what so ever.
If the person at 123-8888 hangs up and calls me right back (same
handset on both sides) same trunk line
The call always has echo on it. The Asterisk sip extension
hears them selves echoing. The remote party

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

Echo Canceller Wiring (Tellabs.. HOWTO..?)
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:

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?

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?

AT&T T1 Cable Needed!
Hi,
I just got a T1 interface for a AT&T (became Lucent) System75 (uses same
cards as Definity). I would take a crack at making a cable but can't
determine the pinout for a cable and it is not apparent from the board.
Asking you guys makes sense as one of you may have one of these systems. The
cable has a amphenol male D50 connector on one end and probably a rj45 on
the other. I also

Disk Layout for New Storage Server
We are implementing a ZFS storage server (NAS) to replace a NetApp box. I have a Sun server with two dual Ultra320 PCIX cards connected to 4 shelves of 12 500GB disks each, yielding a total of 24TB of raw storage.
I''m kicking around the different ways to carve this space up, balancing storage space with data integrity. The layout that I have come to think is the best for me is to

Ideal setup for PRI/T1 and TE110P
Hi all, I'm sure something similar has been discussed, but one can only
wade through the archives for so long.
I'm setting up a T1 and my telco has a bunch of questions it wants me to
answer. I know much of the TE110p is configurable to do any of this, but
I wanted to know if there is an optimal or preferred setup.
Any help would be appreciated. Here is the quiz my telco is giving me:

Channelized T1, SIP phones, HW Echo Canceller
I have a channelized T1 coming in from our telco, terminated onto a TE405.
There are three channelbanks serving internal analog extensions, and about
10 Cisco 7960s.
I have no reports of echo on the analog extensions (as expected). The
7960 users complain of occasional echo (seems like 1 in 5 calls). Only
the SIP user hears the echo, not the caller.
I have echocancel=yes, echotraining=yes,

[LLVMdev] Simple question on C program test coverage / dependence analysis
Hi all.
I am new to LLVM, and wondering are there any off-the-shelf tools for C
programs
for measuring testing coverage and simple dependence analysis (within the
LLVM framework).
Specifically, I would like to:
(1) measure which line is covered when executing a C program with specific
input values.
It likes a testing coverage tool, but I hope to get the line number.

Best echo-free and trouble-free system?
We currently have a 15-phone system using Asterisk, a combination of
analog phones/Grandstream HandyTone-286 and Grandstream BT101s, and 4
X100Ps connected to analog lines. The system works well except for
the occasional echo problem. I have all the echo parameters
configured, removed all the extra incoming analog lines except to the
PBX, etc. following all the advice on the wiki and on the

TE411P Really Bad Echo
I just implemented a system using a TE411P hardware echo cancellation
card. Per Digium, I setup zaptel.conf, and zapata.conf the same way as
I always have. To my surprise calls out to the PSTN had a terrible
echo. 1 - 2 second delay, and quite clear. The echo was so bad that I
had to remove the hardware echo cancellation module from the card. We
are only using the 1st span of this card right
