Chapter 1 Overview

Features

A1200P is a modular analog telephony interface product. It is designed for small and medium business PBX. There are up to 12 ports on each A1200P board, so user can setup 4 A1200P cards in one PC to get 48 ports. A1200P series must be used with FXO-100 and FXS-100 together to build a workable system. The FXO-100 and FXS-100 modules are also pin to pin compatible with X100M and S100M.

Misc

1. Operation temperature : 0 to 50°C

2. Storage temperature : - 40 to 125°C

3. Humidity:10 TO 90% NON-CONDENSING

4. Voltage:3.3V,5V

5. Maximal power dissipation:1.7W,6W

Key Benefits

Low CPU Payload :lower than 25% with 8 A1200P(96 ports) after driver installed, on a Celereon D 2.53GHz
Scalable: just add additional cards to extend system
Be easy to use: module Pin to Pin compatible with Digium's X100M and S100M. Users are able to use diguim's X100M/S100M module on this card, or use our FXO-100/ FXS-100 Module on TDM400P

Chapter 2 Software Installation and Configuration

Step 1: Hardware Installation and Setup

There are 3 RJ45 sockets and 8 pins on each for A1200P on the bracket,each RJ45 socket corresponds to 4 FXS/FXO modules.2 pins are a pair connects to your 2-wire telephone line, so each RJ45 socket is divided into 4 telephone lines by a splliter.If the card equips with a FXS, please supply power and plug PSTN line into FXO port and normal telephone line into FXS.

Step 2: Software Installation

A1200P supports dahdi software device driver on Linux. To make full use of A1200P, you should install Dahdi and asterisk.

Get all necessary software packages

A1200P device driver is a signal file named opvxa1200.c, it can be downloaded from http://downloads.openvox.cn/pub/drivers/dahdi-patches/dahdi_2.4_a800_a1200/

Note that there is kernel source in the system, if not, you should install it by running "yum install kernel-devel".Before installing Dahdi and asterisk, please make sure some support packages have been installed.

It is time to check for the availability of support 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 execute yum like below 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++

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

2. Download and modification
2.1. Please go to www.asterisk.org to download asterisk-1.6-XX, dahdi-linux-XX and dahdi -tools-XX and unzip the files to /usr/src
2.2. Copy opvxa1200.c to /usr/src/dahdi-linux-xx/driver/dahdi/.
2.3. Open Kbuild under /usr/src/dahdi-linux-xx/driver/dahdi/.
2.4. Find the line: obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCTDM) += wctdm.o
2.5. Add a new line after that line: obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCTDM)+= opvxa1200.o, the file looks like this:

obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCT4XXP) += wct4xxp/
obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCTC4XXP) += wctc4xxp/
obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCTDM24XXP) += wctdm24xxp/
obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCTE12XP) += wcte12xp/
obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCTDM) += wctdm.o
obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCTDM) += opvxa1200.o
// this is for a1200/a800p
obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCT1XXP) += wct1xxp.o
obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCTE11XP) += wcte11xp.o

3. Install dahdi-linux-XX and dahdi-tools-XX

3.1 change directory to /usr/src/dahdi-linux-xx, under that directory, run:

make
make install
make config

3.2 change directory to /usr/src/dahdi-tools-XX, run:

./configure
make
make install

4. Install asterisk
change directory to /usr/src/asterisk-1.6.XX, run:

./configure
make
make install
make samples

5. Check and modify configuration files

Detect and load modules for opvxa1200:
run command: dahdi_genconf, the command 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 the command:
echo "#include dahdi-channels.conf" >> /etc/asterisk/chan_dahdi.conf
Check and edit /etc/dahdi/system.conf,it should be like:

# Span 1: OPVXA1200/0 "OpenVox A1200P Board 1" (MASTER)

6. Load the driver by these commands:

modprobe dahdi  ; load dahdi driver
modprobe opvxa1200 opermode=YOUR　COUNTRY; load the a1200/a800 driver with your country 
dahdi_cfg –vvvv ; start channels

7. Start asterisk and test calls
Check the dahdi channels by loading from asterisk console:

asterisk –vvvvvvvgc

After entering asterisk console, run command: dahdi show channels. If dahdi channels are found, it means the dahdi channels have been loaded into asterisk.

zhu*CLI> dahdi show channels
Chan Extension  Context         Language   MOH Interpret
pseudo          default                    default
      1         from-pstn                  default
      2         from-pstn                  default
      3         from-internal              default
      4         from-internal              default

User must make sure that the context "from-pstn" and "from-internal" are in extensions.conf, here an example is given:

[from-pstn]
exten => s,1,Answer() // answer an inbound call
exten => s,n,Playback(cc_welcome) // please a message
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

Test environments are:

Centos-5.3 
Kernel version: 2.6.18-8.el5 
dahdi-linux: 2.2.0
dahdi-tools: 2.2.0 
Asterisk: 1.6.0.10 
Hardware: OpenVox A1200P
