Chapter 2 Hardware Setup

There are some points that should be paid attention to when set up V100-PTMC. In addition, OpenVox design and manufacture V100_PTCCEVB evaluation board to help the customers to evaluate the V100-PTMC on standard PCI bus.

The following is the V100-PTMC image

 image2015 11 18%2010:39:46

                            Figure 2 V100-PTMC

 

2.1 Hardware Introduction

1. Vocallo DSP and Core Module

The Vocallo DSP, which is used to address transcoding, is located in the core module. The media flow enters and exits through inherent MAC interface and TDM bus interface while the control flow enters and exits just through inherent MAC interface.

2. Giga NIC

The Giga NIC located in extender PMC board bridges the host located in PCC/PTxCC through PCI bus to the vocallo DSP through Eth1.

3. Front Panel RJ45

The front panel RJ45 inextender PMC board supports to provide the packet interface to access the DSP. In some applications, the remote host can communicate with the Vocallo DSP through the front panel RJ45 interface. The interface is always available except PT5MC option is chosen.

4. P4 in PTMC Connectors

The P4 is another packet interface to access the DSP. This interface enables when PT5MC option is chosen.

 

5. PTMC Connectors

There are four PTMC connectors, which are compliant with PCIMG2.15 (PTMC) electrical specification and IEEE1386, IEEE1386.1 (PMC) mechanical specifications, located in V100-PTMC.

6.     Glue

The glue located in extender PMC board bridges the UART and H.110 bus in PMC carrier/PTxCC to the Uart and TDM bus in core module.

 

2.2 Dip Switch Setup

The Dip switch located at extender PMC board is for configuring the V100-PTMC options.

The following is the Dip Switch Outline.

image2015 11 18%2010:40:16

Figure 3 Dip Switch

 

Pin 1 is Vocallo DSP Device ID option. If it is ON, the DSP ID is 0x FE. If it is switched to OFF (default), that means the DSP ID is 0x FF. If dual V100-PTMCs are provided on the same PCC/PTCC, one of them should be set to 0x FE, and the other should be set to 0xFF.

Pin 2 is TDM clock of Vocallo DSP enable option. If it is ON, the TDM clock is disabled (default). If it is switched to OFF, the TDM clock is enabled.

Pin3, Pin4 and Pin5 are PTMC configuration options. The V100-PTMC supports 3 PTMC configurations (PT2MC, PT3MC, PT5MC) via Pin3, Pin4, and Pin5. Status “ON” represents binary digital “1”, while “OFF” means 0. For Example, if Pin3-Pin5 is set to 010, PT2MC (default) configuration is enabled. If Pin3-Pin5 is set to 011, PT3MC configuration is enabled. If Pin3-Pin5 is set to 101, PT5MC configuration is enabled.

2.3 LED Indicator

There are 4 LEDs located on the front panel.

 

image2015 11 18%2010:40:46

Figure 4 Front panel

The T/R flash indicates the front panel RJ45 or P4 in PTMC connectors packet interface is transmitting or receiving data normally.

The LNK light indicates the front panel RJ45 packet interface or P4 in PTMC connectors packet interface is linking up.

The CFG2/3 is PT2MC/PT3MC indicator. If the CFG2/3 is red, which means V100-PTMC is PT2MC option and the PTCC is PT2CC compliant. While if CFG2/3 is green, it means V100-PTMC is PT3MC option and the PTCC is PT3CC compliant.

The CFG5 is PT5MC indicator. Green light means V100-PTMC is PT5MC option and the PTCC is PT5CC compliant.

2.4 Hardware Installation Procedures

  1.  Make sure the V100-PTMC is compatible with your PCC/PTCC. V100-PTMC can be worked together with PCC32, PCC64, PT2CC, PT3CC and PT5CC theoretically. In practice, Electrical compatibility of combinations that include user-defined I/O, whether PMC or PTMC compliant, must be taken into account. The V100-PTMC I/O pins are 5V tolerant for 3.3V. It is recommended that you may consult to our technical support whether the V100-PTMC suits your application.V100_PTCCEVB is a PCI card for evaluating V100-PTMC’s availability.
  2.  Make sure the PCC/PTxCC that has V100-PTMC installed complies with the country specific safety regulations.
  3.  Power off your PCC/PTxCC and unplug it from its AC power source.
  4.  Wear an Anti-static Wrist Strap on your wrist.
  5.  Configure the Dip Switch to the right position.
  6.  Open the cover of the Comppact PCI Platform.
  7.  Remove the filler plate from the front panel of the PCC/PTxCC. (See Figure 5)
  8.  The V100-PTMC must be positioned with care to avoid damaging components against the voltage key post.
  9.  The V100-PTMC bezel enters the front panel of the PCC/PTxCC into alignment with the signal connectors. (See Figure 5)
  10. Mount the screws. (See Figure 5)
  11. Replace the cover of the PCC/PTxCC.
  12. Plug the UTP cable into RJ45 Jack of the V100-PTMC only if the Media/Control Path is the front panel RJ45/UTP.
  13. Plug the AC power source.

Figure 6 SELinux configuration file

1. Software installation

Some dependencies are crucial. If any of them is absent, the software installation process would not go through successfully. Let’s run “yum install XX“ (XX stands for the dependency’s name) to check the availability of dependencies.

# 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++

# yum install libxml2

# yum install libxml2-devel

 

If there is no kernel source in the system, users should also install it by running like:

# yum install kernel-devel

If the dependency has been installed, system indicates that nothing to do which means you could go to the next one directly. Otherwise, the system will keep on installing it.

 

Among DAHDI, Asterisk and V100-PTMC, let’s install DAHDI firstly. Please execute those commands under the directory of /usr/src/ in generally:

 

# cd /usr/src

# tar –xzvf openvox_dahdi- linux-complete-XX

# cd dahdi-linux-complete-XX

# make

# make install

# make config

 

   image2015 11 18%2010:42:16     Caution: If there is something wrong after “make“, please refer to HERE. In the url link, the moderator introduces you a method how to patch. After patching, save your changes and exit. Then run “make“ again, if successfully done, it is time for you to install Asterisk.

Please operate those commands to install Asterisk.

 

# cd /usr/src/

# tar –xzvf astersik-XX.tar.gz

# cd asterisk-XX

# ./configure

# make

# make install

# make samples

 

Please operate those commands to install V100-PTMC

 

# cd /usr/src

# tar –xzvf opvx_tc_linux_x86-1.0.0.tar.gz

# cd opvx_tc_linux_x86-1.0.0/libopxtc/

# make install

# cd /usr/src/opvx_tc_linux_x86-1.0/codec/asterisk

# make install          

 

2. Configuration

2.1 Modify openvox_codec.conf

 

# vim /etc/asterisk/openvox_codec.conf

 

A. If using P1,P2 in PTMC connectors(PCI bus) as communication interface, in this situation, please simultaneously plugging V100-PTMC and asterisk cards to the same server. Sample configuration file openvox_codec.conf is as follows.

If your V100-PTMC is recognized as eth1 by the system, then you need to change the ethX to eth1. One thing you need to note is place V100-PTMC NIC IP and vocalloaddr IP to same network segment, and make these two IPs are different.

B. If using Front panel RJ45 or Back panel RJ45 on your server as communication interface, please directly ignore step 2.2 below. In this case, you will need another PC to provide power to V100-PTMC. Plug V100-PTMC to the PC, and then connect the Asterisk server with the PC over cable or other network devices.Sample of configuration file openvox_codec.conf are as follows.

 image2015 11 18%2010:44:26

The X in ethX means the number of the network device that connects with Asterisk server. For example, if your server has two network interface cards, one is eth0, and the other is eth1, and suppose to connect eth1 with V100-PTMC, then you will need to modify X to 1 and modify vocalloaddr to the same network segment as eth1.You can also connect the V100-PTMC through other devices, such as router、switches and so on.

2.2 Setting V100-PTMC NIC IP by running the below command. Right here, let’s take eth1 for an example.

 

# vim /etc/sysconfig/network-scripts/ifcfg-eth1

 

Set BOOTPROTO =static

Add two line: IPADDR=10.1.1.80

NETMASK=255.255.255.0

                                                          image2015 11 18%2010:44:48

Figure 7 ifcfg-eth1 configurations

 

After the network settings, remember to perform “service network restart” to restart the network and activate V100-PTMC NIC. See more V100-PTMC details by “ifconfig“.

2.3 Before starting Asterisk, please run “vim /etc/asterisk/modules.conf“, and add a line “noload => res_timing_pthread.so” at the end of modules.conf, it will disable the timing module. Otherwise, it’s going to display many errors from asterisk.

2.4 Enable asterisk by running “asterisk –vvvvvvvgc“, if it has been started before, run “asterisk -r” instead. In the CLI, perform “module load codec_openvox.so” to load V100-PTMC driver.

After entering into CLI, type “op” and press Tab. If it displays openvox, which means installation finished elementarily. Please also perform other commands to check related information, for instance, run “openvox show translators” to show supportive code conversion mode.
