Chapter 2 Card Installation and Configuration

1. Hardware Installation and Setup
Attention：if you found J914（input）and J915（output）interfaces on the card, it means the card support clock line, for the detail information, please refer to the following link：

http://bbs.openvox.cn/viewthread.php?tid=874&extra=page%3D1

Before inserting the D110P card into PCI slot, customer should set the jumpers correctly. There are few steps go through:
1) SPAN Type Setup
P5 controls the function of each span at E1 or T1 mode.

2. Software Installation and Setup
D110E supports original dahdi wcte11xp driver. There are few steps to install wcte11xp drivers.

2.1 Checking the D110P hardware Run the command: lspci -vvvvvv, user should see the this info:

2.2 Checking and installing packages

Before installing dahdi and asterisk, please make sure that some supporting packages have been installed.

Note that if there is no kernel source in the system, user should install them. User can run yum again: yum install kernel-devel. It is time to check for the availability of some supporting packages:

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 some packages are not installed, please install them by using yum to install

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++

2.3 Download and Compile Libpri,Dahdi and Asterisk

Please download libpri, dahdi-linux-complete-XX and asterisk 1.8.XX from http://downloads.asterisk.org/pub/telephony/
Here，assuming these packages are stored in /usr/src directory. Customers compile those packages as following in order:

2.3.1 Compile libpri-XX:

cd /usr/src/libpri-XX
make clean
make
make install

2.3.2 Compile dahdi

cd /usr/src/dahdi-linux-complete-xx
make
make install 
make config

2.3.3 Compile asterisk

cd /usr/src/asterisk-1.8.X
./configure
make
make install
make samples 

2.4 Loader driver Load the driver by these commands:

modprobe dahdi  ; load dahdi driver
modprobe wcte11xp opermode=YOUR　COUNTRY; load the wctdm driver with your country 
dahdi_genconf  ;Generate configure files
dahdi_cfg –vvvv ; start channels

The command dahdi_genconf will automatically generate the /etc/dahdi/system.conf and /etc/asterisk/dahdi-channels.conf.
Note: the dahdi-channels.conf should be included in /etc/asterisk/chan_dahdi.conf
if not, please run a command to include that file:
echo "#include dahdi-channels.conf" >> /etc/asterisk/chan_dahdi.conf

2.5 Configuration

1) The file /etc/dahdi/system.conf should looks like the following

span=1,1,1,ccs,hdb3
# termtype: te
bchan=1-15,17-31
dchan=16
echocanceller=mg2,1-15,17-31

# Global data
loadzone        = cn
defaultzone     = cn

2) The file /etc/asterisk/dahdi-channels.conf should looks like the following

group=0,11
context=from-pstn
switchtype = euroisdn
signalling=pri_cpe
channel => 1-15,17-31

3) edit asterisk/extension.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 dahdi 1
exten => 200,2,Hangup

4) Start asterisk by asterisk -vvvvvvgc, under asterisk console:

run: "dahdi show channels"; there should be some channels, if the system setting is correct.
run: "pri show spans" ; the spans must be up and active
if the two results are in a normal status, the calls should be made.
