The newer A101 and A102 T1/E1 cards from Sangoma use a slightly different wanpipe setup than the older S series cards. There is now an option to set HDLC Streaming as the protocol. The following directions from Sangoma are included below.

See also an example wanpipe1.conf for the A101 and A102 cards.

From the wanpipe/doc/README.hdlc_api:

WANPIPE (RAW) HDLC STREAMING API Support
========================================


Author: Nenad Corbic 



Pre requisites
--------------

1. A Linux kernel source must be available.
   Usually in /usr/src/linux directory.
   
   Furthermore, the linux source version must
   match the currently running image.

   i.e. Output of 'uname -r'
        must match the source version
	number in /usr/src/linux/Makefile.

   Note: The Setup installation script checks
         for this condition and will take
	 appropriate steps to resolve the
	 name mismatch.




Installing WANPIPE with RAW HDLC support
----------------------------------------

The HDLC API support IS installed by default
during WANPIPE installation process.

Use the CUSTOM driver compilation 
option in 
    ./Setup install
script to enable CHDLC.

After successful installation proceed to 
configure you RAW HDLC card using:

For AFT cards:
	/usr/sbin/wancfg
For Legacy S514 cards:
	/usr/sbin/wancfg_legacy
 
GUI configurator.


Installation Verification
-------------------------

Run wanpipe hardware probe to
make sure that the kernel modules
are working fine:

Run:	wanrouter hwprobe


	In case of error:

Configuring RAW HDLC API : AFT cards
------------------------------------

Run /usr/sbin/wancfg

1. Select card from Hardware Probe

2. Configure for T1 or E1 (Default T1)

3. Select HDLC Streaming Protocol

4. Under Interface Section

   Selcect API operation mode.

5. Save exit


NOTE: 
To Disable HDLC engine per interface
one can manually change HDLC_STREAMING NO option
to NO under interface section in /etc/wanpipe/ 
wanpip#.conf config file. 
This MODE is called TRANSPARENT.

IMPORTANT: When configuring for Transparent mode (HDLC Disabled)
           The MTU/MRU must be in multiples of channel numbers
           eg: T1 = 24 channels: 24*50  MTU/MRU=1200
               E1 = 31 channels: 31*40  MTU/MRU=1240
	
		

Configuring RAW HDLC API : Legacy S514
--------------------------------------

Run: /usr/sbin/wancfg_legacy

1. Create new device

2. Select wanpipe1

3. Protocol Section
	Select Protocol: Cisco HDLC Protocol

4. Hardware Section
	Select Probe Hardware
		Select your adapter.


5. T1/E1 CSU/DSU Configuration (Optional)
