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

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.
2.1 Checking card D410P
Run the command: lspci –vvvv, user can say the following info:
00:0c.0 Network controller: Tiger Jet Network Inc. Tiger3XX Modem/ISDN interface Subsystem: Unknown device 79fe:0001 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 32 (250ns min, 32000ns max) Interrupt: pin A routed to IRQ 201 Region 0: I/O ports at b800 [size=256] Region 1: Memory at febfe000 (32-bit, non-prefetchable) [size=4K] Capabilities: [40] Power Management version 2 Flags: PMEClk- DSI+ D1- D2+ AuxCurrent=55mA PME(D0+,D1-,D2+,D3hot+,D3cold+) Status: D0 PME-Enable- DSel=0 DScale=0 PME-
2.2 Checking and Installing the packages
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.
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++
2.3 Downloading and Compiling libpri,dahdi and asterisk
To make the asterisk and dahdi running, users have to download libpri, please dahdi and asterisk from http://downloads.asterisk.org/pub/telephony/
Here, assuming that the packages are stored in /usr/src directory. User compile these packages as following in order.
2.3.1 Install libpri:
cd /usr/src/libpri make clean make make install
2.3.2 Install dahdi-linux-complete, go to /usr/src/dahdi-linux-complete-xx, run:
make make install make config
2.3.3 Install asterisk, go to /usr/src/asterisk-1.8.XX, run:
cd /usr/src/asterisk-1.8.XX ./configure make make install make samples
2.4 Loader driver Load the driver by these commands:
modprobe dahdi ; load dahdi driver modprobe wct4xxp opermode=YOUR COUNTRY; load the 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 # 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 bchan=63-77,79-93 dchan=78 echocanceller=mg2,63-77,79-93 # Span 4: TE4/0/4 "T4XXP (PCI) Card 0 Span 4" span=4,4,0,ccs,hdb3,crc4 # termtype: te bchan=94-108,110-124 dchan=109 echocanceller=mg2,94-108,110-124 # Global data loadzone = cn defaultzone = cn
2) The file dahdi-channels.conf should looks like the following:
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
3) 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 dahdi channel 1 exten => 200,2,Hangup
4) Start asterisk by run: asterisk -vvvgc, under asterisk console, run
"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.
"pri show spans", make sure that pri is up and active.
If there is no any problem with "dahdi show channels" and "pri show spans", users should be able to make inbound and outbound calls.
