Connecting DATA 0 Interface

The information below will provide the user with a basic setup sequence for connecting the IMG 1010 to a VoIP network utilizing SIP or H.323 signaling. The DATA interfaces are Gigabit-Ethernet ports and are typically used to pass RTP traffic. Depending on how the ports are configured, they can be configured to be on the same secure IP network as the CTRL 0 interface (Management Network), or can be connected to a separate public network to be used for VoIP Signaling and RTP traffic.

• Connect the cables as shown in the figure below. The figure below displays the DATA 0 interface being connected to a public network.
  
  

• The DATA 0 interface located on the rear of the IMG 1010 and is a Gigabit-Ethernet port dedicated to VoIP Bearer traffic (RTP) or SIP/H.323 signaling. Refer to the the topics under the IMG 1010-Installation and Setup Guide > IMG 1010-Hardware Installation book for more information on connecting to this interface.

Connecting TDM Signaling and Bearer Ports

The Bearer spans (Interface Offsets) 0-27 are connected to a TDM network. Each bearer interface which represents one DS1 can have signaling and/or bearer DS0’s configured on them. The Signaling/Timing interfaces can be connected to the TDM network as well. These interfaces are typically used for SS7 or ISDN signaling but can be used for any TDM functionality as well. Refer to IMG 1010 - T1-E1 for more information.

Configure Pre-loaded GCEMS server

When purchasing an IMG 1010, the customer has the option of purchasing a server which is labeled the GCEMS server. This server has been pre-loaded with a version of Red Hat Enterprise Linux OS along with all the applications and services needed to start configuring the IMG 1010. If the GCEMS server was purchased through Sangoma, follow the procedure below. The procedure below describes configuring the GCEMS server to operate in your specific network. The first ethernet port on the GCEMS server is pre-configured with an address of 192.168.0.100. This IP address can be used to connect to the GCEMS server to make further changes to the host configuration

Update /etc/hosts and /etc/sysconfig/network files

• In the /etc/hosts file, there are two entries. The first is mapped to 127.0.0.1. Do not edit this. The second is a factory default set up during configuration and testing at the factory. Using a text editor such as a vi or gedit, modify the default factory settings to equal the hostname and ip address being given to the GCEMS server. See example of default file below

• Edit the HOSTNAME=<hostname> line in the /etc/sysconfig/network file so the value given to <hostname> is the same hostname being modified in /etc/hosts file in previous step.

Create symbolic link to load system software

To install the System Software into the IMG, the FTP Server being utilized (Usually GCEMS Server) should have one of two things to allow software to be loaded.

• A pathname to the specific software that is to be installed -or-

• Have a link generated in the ftp server that points a generic name (img1010_id0101.bin) to a specific software file.

The procedure below describes the latter. Creating a link will allow the user to change software builds in the IMG easily. The link generated will create an association between the filename line in the dhcpd.conf file located in /etc and the latest version software being installed. The link will be created in the /home/excelsw/ftpBuilds folder. A script has been written that will create the symbolic link described above. This script was written to make it easier to change the symbolic link each time a new build is to be installed. Follow the procedure below to create the symbolic link through the lnimg script.

• Copy the script file labeled lnimg located in the /opt/dialogic/common/osconfig directory and paste it into the /home/excelsw/ftpBuilds directory.

  • From the ftpBuilds run the lnimg \(link img) script

• Follow the instructions and enter the appropriate IMG 1010 Build Number from the Available IMG 1010 Build files. Use the format described in the lnimg script. (1051=10.5.1, 1052=10.5.2, 1053=10.5.3).

  • The following response will be generated:

• Executing the ls -la command as shown above, verifies that the link was created.

Create dhcpd.conf file

Create the dhcpd.conf file. The IP information, codec information, and protocol information for the IMG and GCEMS server should be determined before starting the xldhcpd script. Also, the MAC address of the CTRL 0 interface can be obtained from sticker located on bottom of IMG 1010 chassis.

As Super User, create a dhcpd.conf file. Run the dhcpd file creation script located in the following /opt/dialogic/common/osconfig directory.

Enter values when prompted as appropriate for your configuration. You will be prompted for the following information: [factory defaults shown in bold]

The following is the response after all prompts are complete:

• The file will be created in the /opt/dialogic/common/osconfig directory.

• Move the file to the /etc directory

Start the services nfs, vsftpd, dhcpd, and ntpd services

• As a Super User, start all the services and configure them to restart when GCEMS server is rebooted. Enter the following commands to start the nfs server.

• Enter the following commands to start vsftpd service.#/sbin/service vsftpd start   (Start the vsftpd service)

• Enter the following commands to start dhcpd service.

• Enter the following commands to start ntpd service.

• Once these services are running and the IMG software build is available the software can be downloaded. Refer to IMG 1010 - Downloading System Software and download the system software from the GCEMS server to the IMG 1010.

Install GCEMS software.

To take advantage of all new features, it is recommended that the latest version of GCEMS software be installed on the GCEMS Server. The most current software can be obtained from the Sangoma Technical Support website.

• Go to the Sangoma BBS Website at http://excelbbs.sangoma.com/default.htm

• Select "Download Information" and then to file area "357. IMG 10.5.3". You will require a logon username and password to access the downloads site. (A support contract is needed to access this site.) Within this site will be two software binary files with the following format. Download the latest version of these files.

  • IMG_10.5.3.xxx.bin

  • IMGUserInterface_10.5.3.xxx.bin

• Open a terminal on the GCEMS server and become a root/superuser by entering the command:

• Change the mode to executable for the following files being installed. This is accomplished by executing the following commands:

• Install GCEMS software.

• Install the IMG User Interface

• At the end of the installation you will be prompted to log out. Log out as root user by entering the exit command.
