DE210E User Manual
Chapter 1 Overview
1. What is DE210E
The DE210E is a bundling of our D210E 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. DE210P is fully compatible with Asterisk applications. The open source driver supports an API interface for custom application development.
DE210E supports industry standard telephony and data protocols, including Primary Rate ISDN (both N. American and Standard Euro) protocol families for voice, PPP, Cisco, HDLC, and Frame Relay data modes. Both line-side and trunk-side interfaces are supported.
About OpenVox EC100-64 Module
The OpenVox EC100-64 enables users to eliminate echo tails up to 128ms or 1024 taps across all 64 channels in E1 mode or 48 channels in T1/J1 modes. Further, this module takes advantage of the Octasic Voice Quality Enhancement to provide superior sound quality on all calls.
Benefits: World recognized & deployed best voice quality
Features: 128ms tail/channel (on all channel densities) Octasic Music Protection Adaptive Noise Reduction Automatic Level Control (G.169) Field upgradeable algorithm V.25 / V.8 answer tone (w/ and w/o phase reversal) DTMF as per Q.24
2. What is Asterisk:
The Definition of Asterisk is described as follow:
Asterisk is a complete PBX in software. It runs on Linux,BSD,Windows (emulated) and provides all of the features you would expect from a PBX and more. Asterisk does voice over IP in four protocols, and can interoperate with almost all standards-based telephony equipment using relatively inexpensive hardware.
Asterisk provides:
1) Voicemail services with Directory
2) Call Conferencing
3) Interactive Voice Response
4) Call Queuing
5) Support for three-way calling, caller ID services
6) ADSI, IAX, SIP, H.323, MGCP and SCCP/Skinny.
Chapter 2 Card Installation and Configuration
1. Hardware Installation and Setup
Before inserting the DE210E card in to PC-express slot, customer should set the jumpers correctly. Customers should check:
1) SPAN Type Setup
P5 controls the function of each span at E1 or T1 mode.
2) Software Installation and Setup
DE210E supports original zaptel wct4xxp driver. Customers can download zaptel driver from asterisk.org. There are few steps to install wct4xxp drivers.
Checking the hardware by command: lspci -v
Downloading and compiling, to make the asterisk and zaptel running, users have to download libpri, zaptel and asterisk. For more details about source of these packages, please visit the asterisk.org.
Note:
If there is no kernel source in the system, user should install them. User can run yum again: yum install kernel-devel. If the kernel is smp kernel, please run this command: yum install kernel-smp-devel.
Checking and installing these packages before proceeding with the installation of Asterisk.
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 one of the packages is missed, please install that as follow:
yum install bison 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++
Here，assuming the three packages are stored in /usr/src directory. Customers compile those packages as following in ORDER:
1. Installing libpri:
cd /usr/src/libpri make clean make make install
2. Installing zaptel
cd /usr/src/zaptel make clean make make install
3. Installing asterisk
cd /usr/src/asterisk make clean make make install
Loading wct4xxp driver for DE210E, editing zaptel.conf:
span=1,1,1,ccs,hdb3 # termtype: te bchan=1-15,17-31 dchan=16 # 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 # Global data loadzone = us defaultzone = us
modprobe zaptel modprobe wct4xxp ztcfg –vvvvvvvv dmesg
Configuring zapata.conf and extensions.conf
1) Edit the zapata.conf by vi /etc/asterisk/zapata.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=1 signalling=pri_cpe channel => 1-15,17-31 group=2 signalling=pri_cpe channel => 32-46,48-62
2) Edit the extensions.conf by vi /etc/asterisk/extensions.conf:
[from-pstn] exten => s,1,Answer() // answer the inbound call exten => s,n,Playback(cc_welcome) // please message exten => s,n,Hangup() [from-internal] // test outbound calls exten => 200,1,Dial(zap/1/outgoing_number) // dial 200 to dialout from zap 1 exten => 200,2,Hangup
3)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 2 span(s)
4) Starting asterisk by asterisk –vvvvvvvgc
after starting asterisk, please check the zap channels. Under asterisk console,
check the status of card by these commands:
zap show channels. It should shows zap channels, if the zapata.conf is correct. pri show spans. It will show the status of the physical connections. MUST be UP, active to make calls.
