DE410E User Manual
Chapter 1 Overview
1. What is DE410E?
The DE410E is a bundling of our leading D410E product and our new EC100 Octasic DSP-based echo cancellation module. The EC100 provides a certified carrier-grade algorithm that has been labeled a benchmark for echo cancellation for OpenVox.
With the improved I/O speed, the card reduces CPU usage and increased card density per server. DE410E is fully compatible with Asterisk applications. The open source driver supports an API interface for custom application development.
DE410E supports industry standard telephony and data protocols, including:
1) Primary Rate ISDN (both N. American and Standard Euro) protocol families for voice
2) PPP, Cisco, HDLC, and Frame Relay data modes. Both line-side and trunk-side interfaces are supported.

Chapter 2 Card Installation and Configuration
1. Hardware Installation and Setup
Before inserting the DE410E card in to PCI-e slot, customer should set the jumpers correctly. Please check:
1) SPAN Type Setup
Jumper P5 can be adjusted for each span at E1 or T1 mode.
2) Software Installation and Setup
D410P supports original dahdi wct4xxp driver. There are few steps to install wct4xxp drivers.
To make the asterisk and dahdi running, users have to download libpri, dahdi and asterisk. For more details about source of these packages, please visit:www.asterisk.org.
Note:
If there is no kernel source in the system, user should install it. Run command: yum install kernel-devel. If the kernel is smp kernel, please run this command: yum install kernel-smp-devel.
2.1) Checking the support packages for libpri,dahdi and asterisk：
rpm -q kernel-devel rpm -q bison rpm -q bison-devel rpm -q ncurses rpm -q ncurses-devel rpm -q zlib rpm -q zlib-devel rpm -q openssl rpm -q openssl-devel rpm -q gnutls-devel rpm -q gcc rpm -q gcc-c++
if missing any package, please install that.
yum install bison yum install kernel-devel yum install bison-devel yum install ncurses yum install ncurses-devel yum install zlib yum install zlib-devel yum install openssl yum install openssl-devel yum install gnutls-devel yum install gcc yum install gcc-c++
2.2）Start CentOS 5.3, enter the system，enter the command: lspci –vvvv

2.3) Install libpri:
cd /usr/src/libpri make clean make make install
2.4）Install dahdi-linux, go to /usr/src/dahdi-linux-xxxx, run:
make make install
2.5）Install dahdi-tools, go to /usr/src/dahdi-tools-xxxx, run:
./configure make make install
2.6) Install asterisk, go to /usr/src/asterisk-1.6.x.x, run:
cd /usr/src/asterisk-1.6.XX ./configure make make install make samples
2.7）Edit the file(etc/dahdi/system.conf),please disable software echocanceller mg2. Make it like the following:
span=1,1,1,ccs,hdb3 # termtype: te bchan=1-15,17-31 dchan=16 #echocanceller=mg2,1-15,17-31 # Span 2: TE4/0/2 "T4XXP (PCI) Card 0 Span 2" span=2,2,1,ccs,hdb3 # termtype: te bchan=32-46,48-62 dchan=47 #echocanceller=mg2,32-46,48-62 # Span 3: TE4/0/3 "T4XXP (PCI) Card 0 Span 3" span=3,3,0,ccs,hdb3,crc4 # termtype: te bchan=63-77,79-93 dchan=78 #echocanceller=mg2,63-77,79-93 # Span 4: TE4/0/4 "T4XXP (PCI) Card 0 Span 4" span=4,4,0,ccs,hdb3,crc4 # termtype: te bchan=94-108,110-124 dchan=109 #echocanceller=mg2,94-108,110-124 # Global data loadzone = cn defaultzone = cn
2.8) Edit chan_dahdi.conf by vi /etc/asterisk/chan_dahdi.conf:
[channels] context=zap-in switchtype=euroisdn pridialplan=national signalling=pri_cpe usecallerid=yes hidecallerid=no callwaiting=yes callwaitingcallerid=yes threewaycalling=yes transfer=yes cancallforward=yes echocancel=yes rxgain=0.0 txgain=0.0 group=1 callgroup=1 pickupgroup=1 immediate=no callprogress=no callerid=asreceived group=0,11 context=from-pstn switchtype = euroisdn signalling=pri_cpe channel => 1-15,17-31 group=0,12 context=from-pstn switchtype = euroisdn signalling=pri_cpe channel => 32-46,48-62 group=0,13 context=from-pstn switchtype = euroisdn signalling = pri_cpe channel => 63-77,79-93 group=0,14 context=from-pstn switchtype = euroisdn signalling = pri_cpe channel => 94-108,110-124
2.9) edit the dialplan(/etc/asterisk/extensions.conf)
[from-pstn] exten => s,1,Answer() // answer the inbound call exten => s,n,Playback(cc_welcome) // please mesaage exten => s,n,Hangup() [from-internal] exten => 200,1,Dial(dahdi/1/outgoing_number) // dial 200 to dialout from zap 1 exten => 200,2,Hangup
2.10) Load driver wct4xxp, run commands:
modprobe dahdi ; load dahdi modprobe wct4xxp ; load the card driver dahdi_cfg -vvvv ; start the channels
2.10.1) Check the echocancel module
run command: dmesg | grep VPM if you find the output like this,the module is working: VPM450: Present and operational servicing 4 span(s)
2.11) Start asterisk by run: asterisk -vvvgc, under asterisk console, run
2.11.1) "dahdi show channels", There should be some channels. if there is no channels, please check the chan_daid.conf, make sure the content in the chan_dahdi.conf is correct.
2.11.2) "pri show spans", make sure that pri is up and active.
If there is no any problem with step 2.11.1 and step 2.11.2, users should be able to make inbound and outbound calls.
