Hardware Installation
Mount your transcoder
-> D150-ETH-Find a free PCI slot insider a server to install
-> D150-BOX- Find a well ventilated flat surface, or install in optional rack mount
---------Attach Power supply
-> D150-ETH- use molex power from server power supply 2A @ 5V (10W),
or external power supply 2A @ 5V (10W)
-> D150-BOX- external power supply 2A @ 5V (10W)
---------Plug the Ethernet cable into your transcoder to attach to your network
* Note: There is no on-board Ethernet switch on the D150, so once plugging in the Ethernet Cable, there is direct access to the transcoding module
...
*Note: This step assumes Asterisk is on the same server as the server hosting the sngtc_server. If Asterisk only exists on other server(s) please go to -> D150 Sngtc Server Configuration
The steps below will install the Asterisk trancoding module, so please insure you have the Asterisk headers already installed (ie: /usr/include/asterisk/)
...
By default G729 is the only codec registered with Asterisk. If you require additional codecs please go to the following wiki page to configure them --> codec support and configuration.

Operation
The sngtc_server is at the heart of the transcoding environment. It interfaces the transcoder hardware and codec module (the codec module, in asterisk, communicates with the sngtc_server in order to pass information to/from transcoder). It controls all Sangoma transcoders that are located on the same computer (this means you cannot have multiple sngtc_servers controlling/communicating with specific transcoders).
The sngtc_server needs to be started before transcoding can be done. Below is the usage of the sngtc_server_ctrl command.
