1.2 What is D830P/DE830P
DE830P is a D830P with an EC module, they are new products of the
Digital cards. It’s supposed to be the most advanced 8 port T1/E1/J1
Asterisk
®
card with superior quality in the open source community. The leading innovation ensures users to adjust the interrupt frequency to reduce the CPU load up to 70% and adjust the interrupt pin to avoid interrupt number sharing or conflict. DE830P offers an on-board Octasic
®
DSP-based echo cancellation module. It supports T1, E1, and J1 environments and is selectable on a per-card or per-port basis. The
Octasic
®
DSP-based EC module enables users to eliminate echo tails up to 128ms or 1024 taps across all 256 channels in E1 mode or 192 channels in T1/J1 modes. Furthermore, this module takes advantage of the Octasic
®
Voice Quality Enhancement to provide superior sound quality on all calls. D830P/DE830P 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.
D830P/DE830P works with Asterisk
®
, Elastix
® , FreeSWITCH™, PBX in a Flash, trixbox
® , Yate™ and IPPBX/IVR projects as well as other Open
Source and proprietary PBX, Switch, IVR, and VoIP gateway applications.

Chapter 2 Hardware Setup
There are some points that should be paid attention to when set up
D830P/DE830P.
2.1 Span type setup
Each DIP switch controls one span configuration for E1 or T1 mode.
Setting DIP1 to ON means SPAN1 will be E1.Setting DIP1 to OFF means SPAN1 will be T1.
2.2 Card ID switch setup
If want to install more than one card of D830P/DE830P in a PC, you should take care of the card ID switch. There are two pieces of rules you must obey:
The first Card must be set to 0, which is a card that will be initialized
(i.e. installing driver) firstly when the system boot up. And the second should be set to 1, and so forth.
At most cases, Linux will initialize PCI devices according to their slot order. The slot nearest to the CPU will be initialized firstly and the far end slot will be initialized at last. That is to say, the card which is nearest to the CPU ID should be set to 0 if there is more than one
D830P/DE830P on your machine.

2.3 Slot compatibility
D830P/DE830P is compatible with 32-bit 5.0V PCI slot, 64-bit 3.3V PCI slot or 64-bit 5.0V PCI slot except PCI-E slot; you should confirm your slot type and insert D830P/DE830P into any type of PCI slot as previously described.

2.4 Timing cable
If you have just one card in the system, all channels on that card have already run under the same clock source, so timing cable is unnecessary.
But if there are more than one card, using timing cable has some advantages. Before using the clock line, each card works on its own clock, therefore precision of the clock is limited; each card will send
/receive voice data at different speeds. In voice usage, this small issue can be omitted, but in data communication such as Fax/Modem, it will cause
OpenVox Communication Co. LTD.
URL: www.openvox.cn 10
D830P/DE830P on DAHDI User Manual big problems. Data loss will cause communication broken or fax broken.
Timing cable will force all cards to work at the same clock source, send data at the same speed, as a result no data will lost.
If you found J914 (input) and J915 (output) interfaces on the card, it means the card supports clock line, for details, please refer to HERE .

Figure 3 Hardware detection
If D830P/DE830P is not recognized by the system, you have to power off and take out the card, then try to insert it into other PCI slot.
2. Software installation
Some dependencies are crucial. If any of them is absent, the software installation process would not go through successfully. Let’s run "yum install XX" (XX stands for the dependency’s name) to check the availability of dependencies.
# yum install bison
# yum install bison-devel
# yum install ncurses
OpenVox Communication Co. LTD.
URL: www.openvox.cn 14
D830P/DE830P on DAHDI User Manual
# 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++
# yum install libxml2
If there is no kernel source in the system, users should also install it by running like:
# yum install kernel-devel
If the dependency has been installed, system indicates that nothing to do which means you could go to next one directly. Otherwise, the system will keep on installing it.
Among libpri, DAHDI and Asterisk, let’s install libpri firstly, please execute those commands under the directory of /usr/src/ in generally:
# cd libpri-XX
# make
OpenVox Communication Co. LTD.
URL: www.openvox.cn 15
D830P/DE830P on DAHDI User Manual
# make install
Then change to the directory of dahdi-linux-complete-XX (XX represents
DAHDI version), then perform commands one by one to install DAHDI.
# cd /usr/src/dahdi-linux-complete-XX
# make
# make install
# make config
Caution: If there is something wrong after "make", please refer to HERE . In the url link, the moderator introduces you a method how to patch. After patching, save your changes and exit. Then run "make" again, if successfully done, it is time for you to install Asterisk.
Please operate those commands to install Asterisk.
# cd asterisk-1.8.9.0
# ./configure
# make
# make install
# make samples
OpenVox Communication Co. LTD.
URL: www.openvox.cn 16
D830P/DE830P on DAHDI User Manual
"make samples" will install the standard sample configuration file in the directory /etc/asterisk.
As a freshman, you should perform "make samples", that is to say, it is unnecessary to perform "make samples" every time. Because once performed, it will cover the old sample configuration files you have installed.
3.3 Configuration
1. Driver loading
After compiling and installing DAHDI and Asterisk, please load the driver by running:
# modprobe dahdi
# modprobe wct4xxp
# dahdi_genconf
If there is any error, please trace the cause. Until all errors are clear up, you could execute "dahdi_genconf" again, and then go to the next step.
By running "dahdi_genconf", it will generate /etc/dahdi/system.conf and etc/asterisk/dahdi-channels.conf automatically. Checking whether the generated files information agrees with your hardware setup, if not, you should modify to your specific requirements. Do not forget to confirm
OpenVox Communication Co. LTD.

2. Country mode modification
In order to match your country pattern, you need to change parameters loadzone and defaultzone to your country. For example, your system is in
CHINA, you would like them change to: loadzone = cn defaultzone = cn
Some zonedata is available in the file
.. /dahdi-XX/tools/zonedata.c, you can refer to it to match your country mode. Meanwhile, you also need to modify another parameter which is in file
/etc/asterisk/indications.conf. country=cn
A part of file /etc/asterisk/dahdi-channels.conf is showed as below.

Additional function
Users should run command "cat /proc/interrupts" to check
D830P/DE830P has independent interrupt. If it shares interrupt with other device, it may cause some problems even cannot work normally. While
D830P/DE830P allows users to modify interrupt pin during firmware upgrade for avoiding conflict. Or you can see if the EC module is working as follows:
[root@localhost ~]# dmesg |grep VPM
VPM450: echo cancellation for 256 channels wct4xxp 0000:05:04.0: VPM450: hardware DTMF disabled.
