Chapter 1 Overview

1. What is D410P

D410P is a high-performance, cost-effective four span digital voice card. It provides compact and powerful interface to asterisk that can support E1/T1/J1 and PRI interface. With the improved I/O speed, the card reduces CPU usage and increased card density per server. D410P is fully compatible with Asterisk application. The open source driver supports an API interface for custom application development.

D410P 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.

Other Features Include:
1) Supporting 3.3V and 5V PCI slots
2) High Performance PCI BusMaster with up to 2Kbytes FIFO
3) Be easy to install: Support wct4xxp driver included in original dahdi without any patch

Certificates: CE, FCC

Misc:
1) Temperature Operation: 0 to 50°C
2) Temperature Storage: - 65 to 125°C
3) Humidity:10 TO 90% NON-CONDENSING
4) Voltage:3.3V/5V
5) Power Dissipation Max:2.6W/3.9W

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 D410P card in to PCI 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):

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

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

2.11) 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.
