1.2 What is D210P/DE210P

The DE210P is a D210P with an EC module and they support E1, T1 and
J1 mode. It is selectable on a per-card or per-port basis. This feature
enables signaling translation between E1 and T1 equipments and allows
inexpensive T1 channel banks to connect with E1 circuits.
D210P 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.
D210P 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.

Target Applications

 Voice-over Internet Protocol (VoIP) Services
 Complex IVR Trees
 "Meet-Me" Bridge Conferencing
 Calling Card Platforms
 VoIP Gateways (support SIP, H.323, and IAX)
 Legacy PBX/IVR Services
 Voice/Data Router (replace expensive routers)
 PRI/Switch Compatibility - Network or CPE

Chapter 2 Hardware Setup

There are some points that should be paid attention to when setting up
D210P/DE210P.

2.1 Span type setup

Each DIP switch controls a span configuration for E1 or T1 mode. Setting
DIP1 to ON means SPAN1 will work at E1mode.Setting DIP1 to OFF
means SPAN1 will be T1.

2.2 CardID switch setup

If want to install more than one card of D210P/DE210P 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
D210P/DE210P on your machine.

2.3 Slot compatibility

D210P/DE210P 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 slots; you should confirm your
slot type and insert D210P/DE210P 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

D210P/DE210P on DAHDI User Manual

OpenVox Communication Co. LTD. URL: www.openvox.cn

10

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 D210P/DE210P 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

# yum install ncurses-devel

D210P/DE210P on DAHDI User Manual

OpenVox Communication Co. LTD. URL: www.openvox.cn

14

# 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

# yum install libxml2-devel

If there is no kernel-devel source in the system, users
should run the following command to install the
kernel-devel to peer current kernel:

# yum install kernel-devel-`uname –r`

While if there is no matched kernel-devel found, you should download
matched RPM package to install it, or execute the following command to
update to the latest and stable kernel version:
# yum install kernel kernel-devel
After installed, please reboot your machine to apply the new kernel and
install the dependencies. 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.

15

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

# make install

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.

D210P/DE210P on DAHDI User Manual

OpenVox Communication Co. LTD. URL: www.openvox.cn

16

# cd asterisk-XX

# ./configure

# make

# make install

# make samples

"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

D210P/DE210P on DAHDI User Manual

OpenVox Communication Co. LTD. URL: www.openvox.cn

17

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
dahdi-channels.conf is included in chan_dahdi.conf, if not, run command:

# echo "#include dahdi-channels.conf" >>

/etc/asterisk/chan_dahdi.conf

A part of system.conf which is one of the basic channel configuration
files is displayed.

# Span 1: TE2/0/1 "T2XXP (PCI) Card 0 Span 1" (MASTER)

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.
(Modification, if it is not agree with the hardware setup)

; Span 1: TE2/0/1 "T2XXP (PCI) Card 0 Span 1" (MASTER)
group=0,11
context=from-internal
switchtype = euroisdn
signalling = pri_net
channel => 1-15,17-31
context = default
group = 63

If dahdi channels are found, it means they have been loaded into Asterisk.
You are going to edit dialplan by your requirements.

4. Dialplan edit
Users must make sure that the context "from-pstn" and "from-internal"
are in extensions.conf, here a simple example is given:

# vim /etc/asterisk/extensions.conf

[from-pstn]
exten => s,1,Answer()
exten => s,n,Playback(cc_welcome)
exten => s,n,Hangup()

[from-internal]
exten => _X.,1,Dial(dahdi/g0/${EXTEN})
exten => _X.,n,Hangup

Figure 8 dial plan

Additional function

Users should run command "cat /proc/interrupts" to check
D210P/DE210P has independent interrupt. If it shares interrupt with other
device, it may cause some problems even cannot work normally. Or you
can see if the EC module is working as follows:

[root@localhost ~]# dmesg | grep VPM
VPM450: echo cancellation for 64 channels
wct4xxp 0000:01:03.0: VPM450: hardware DTMF disabled.

Appendix B Hardware settings

Span 2

Span 1

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.

Mode Switch
DIP1:ON:Digium Compatible Model-use wct4xxp directly
OFF:OpenVox dedicate model-use openvox driver
DIP2: ON:Force PCI Burst On,this model will omit noburst
parameter in wct4xxp,always keep using PCI Burst model
OFF:PCI Burst controlled by driver.Burst controlled by
noburst parameter in wct4xxp(default is off)

If there is only one card in PCI slot,CardID switch
should be set to 0,And adding a card the switch
value should be add “1”. For example, there
are two cards, it is need to set the first card’s
switch value to 0 and the second set to 1
