1. Untar LATEST release  

   Code Block
   tar xvfz wanpipe-<version>.tgz

2. Change directory into wanpipe source directory

   Code Block
   cd wanpipe-<version>/

    

3. Compile and install wanpipe driver

   Code Block
   make make install

     

4. To confirm successful installation run:

   Code Block
   wanrouter hwprobe

...

1. Code Block
   wanrouter start

   ->This command will load and configure wanpipe drivers
   -> For full wanrouter usage click here  

2. Full driver log and events are located in /var/log/messages
   ->

   Code Block
   tail -f /var/log/messages

     

3. At this point TDM driver is configured and ready to tx/rx voice & dchan data.  One must make sure that ports are in connected state before trying to tx/rx data using the API programs.
   -> wanrouter status                           #check status of all ports
   -> wanpipemon -i w1g1 -c Ta            #check T1/E1 alarms of each port  

4. Once all ports are connected the ifconfig command can be used to confirm that card running.
   -> ifconfig 
       The rx/tx data packets should be incrementing
       The MTU value indicates the hardware chunk size
       Any rx or tx errors indicate that something is wrong with the data flow.
          -> overruns   : indicate dma problems  or mis-configured system.

...

• SPAN Mode
  Single device per T1/E1 span.
  Data from a single span is passed up to a user as a single chunk of data.
  User has the responsibility to multiplex and de-multiplex data per channel.
  Better performance on higher densities.
  Harder to develop on.

• CHAN mode
  Device per T1/E1 channel
  Highly efficient interrupt logic to minimize number of interrupts.
  High kernel context switching due to large number of devices.
  Easer to develop on. Easily fits into a multi-thread applications.
  Default behavior for Zaptel/DAHDI, FreeSWITCH, SMG

How to turn on/off Echo Canceller by calling libsangoma API

In libsangoma, the API can be called in this way (functions defined in libsangoma.h, and can be called from customer's source code directly to libsangoma):

...

/*!
  \fn int sangoma_tdm_disable_hwec(sng_fd_t fd, wanpipe_api_t *tdm_api)
  \brief Disable HWEC on this channel
  \param fd device file descriptor
  \param tdm_api tdm api command structure
  \return non-zero: error, 0: ok
  
  Supported only on cards that have HWEC
*/
int _LIBSNG_CALL sangoma_tdm_disable_hwec(sng_fd_t fd, wanpipe_api_t *tdm_api);
