Wanpipe configuration for wpchan

wpchan (wanpipe channel) runs on top of the wanpipe API!
B Channels run over Transparent (Bitstream,ulaw,alaw) Mode
D Channels run over Hardware HDCL Mode



Wanpipe E1 PRI Configuration

DChan = channel 16
BChan = channels 1 to 15 and 17 to 31

Run wanpipe configuration utility:

#>/usr/sbin/wancfg

Hardware Setup (AFT):

Select Hardware: Specify AFT card from hardware probe.

    After hardware probe,  wancfg screen should show  you:
    (in case of A104 card)
    ----------------------------
    Card Type-------> A104    
    Physical Medium-> E1    
    ----------------------------
Specify Line Type:  E1
                               

Select Advanced Timeslot Groups Configuration

Set the number of Timeslot Groups to 2.

(one for Dchan and one for Bchan)
(d-channel must be assigned to group 1)
(b-channels must be assigned to group 2)
Select TimeSlot Group 1
Configure Timeslots in Group -> 16

Note: A bug exists on some versions after you select timeslot group the wancfg sends to back to the Advanced Timslot Group Menu.

Timeslot Group 1 Config should look like
--------------------------------------------------
Timeslots in Group-> 16
HDLC Engine --------> Enabled
Idle Char -------------> 0x7E
MTU ------------------> 1500
MRU ------------------> 1500
---------------------------------------------------

(Leave all other options default and select <Back>)

Select TimeSlot Group 2
Configure Timeslots in Group -> 1.15-17.31
(If you get back to the Advanced Timeslot Group Section go back into Timeslot Group 2)

Specify MTU and MRU values. They should be the same.
MTU/MRU values indicate the Rx/Tx CHUNK Size.
To calculate MTU/MRU multiply your desired CHUNK size by the number of active channels.
eg:  30 channels * 40bytes (which is 5ms voice chunk) = 1200 bytes.
By default set the MTU/MRU values to 1200 if you have 30 voice channels.

Configure HDLC Engine to Disable
(HDLC engine -> Disabled)
We must do this step because bchannes carry voice not hdlc frames.

Timeslot Group 2 Config should look like
--------------------------------------------------
Timeslots in Group-> 1-15.17-31
HDLC Engine --------> Disabled
Idle Char -------------> 0x7E
MTU ------------------> 1200
MRU ------------------> 1200
---------------------------------------------------


Your screen should look like this for E1:
--------------------------------------------------
Number of Timeslot Groups ----->2

Timeslot Group 1 configuration -> 16
Timeslot Group 2 configuration -> 1-15.17-31
---------------------------------------------------

Timeslot Groups configuration is complete: Select <BACK>
Default configuration is complete: Select <BACK>

Protocol and Interface Setup:
Select Timeslot group 1 (for the d-channel)

Set protocol to HDLC Streaming

Go to interface setup
Set Operation Mode to: API
Select <BACK>
Select <BACK>

Set protocol to HDLC Streaming
Go to interface setup
Set Operation Mode to: API
Go to Advanced Options
Set HDLC engine to disabled
Set TDMV_HWEC to YES  (for hw echo cancellation)
Select <BACK>
Select <BACK>

Exit and Save configuration file.


Wanpipe T1 PRI Configuration

DChan = channel 24
BChan = channels 1 to 23

Run wanpipe configuration utility:

#>/usr/sbin/wancfg

Hardware Setup (AFT):

Select Hardware: Specify AFT card from hardware probe.

    After hardware probe,  wancfg screen should show  you:
    (in case of A104 card)
    ----------------------------
    Card Type-------> A104    
    Physical Medium-> T1    
    ----------------------------
Specify Line Type:  T1
                               

Select Advanced Timeslot Groups Configuration

Set the number of Timeslot Groups to 2.

(one for Dchan and one for Bchan)
(d-channel must be assigned to group 1)
(b-channels must be assigned to group 2)
Select TimeSlot Group 1
Configure Timeslots in Group -> 24

Note: A bug exists on some versions after you select timeslot group the wancfg sends to back to the Advanced Timslot Group Menu.

Timeslot Group 1 Config should look like
--------------------------------------------------
Timeslots in Group-> 24
HDLC Engine --------> Enabled
Idle Char -------------> 0x7E

Wanpipe Hardware Echo Chancellation Setup

In order to enable hardware echo cancellation on Yate B-Channels you have to manually run wan_ec_client command after wanrouter start. Fortunately wanrouter has external shell scripts that it executes after wanrouter start/stop so you could add wan_ec_client commands to wanrouter startup scripts to automate the process.

To Enable hwec:
wan_ec_client wanpipe1 enable 1-15.17-31

To Desable hwec:

wan_ec_client wanpipe1 disable 1-15.17-31


To automate this step add the start script into the /etc/wanpipe/scripts directory.
(This script will run after wanrouter start)

/etc/wanpipe/scripts/start
--------- CUT ----------
#!/bin/sh
#Ony enable hwec on B-Channels not the D-Channels
wan_ec_client wanpipe1 enable 1-15.17-31
wan_ec_client wanpipe2 enable 1-15.17-31
#Add wan_ec_client calls for each wanpipe device

--------- CUT -----------

To stop all hw echo cancellers on wanrouter stop add this script into /etc/wanpipe/scripts directory.
/etc/wanpipe/scripts/stop
--------- CUT ----------
#!/bin/sh

wan_ec_client wanpipe1 disable 1-15.17-31
wan_ec_client wanpipe2 disable 1-15.17-31

#Add wan_ec_client calls for each wanpipe device
--------- CUT -----------


To check if hwec is enabled on a single span run:

wanpipemon -i w1g1 -c ehw

 

Yate PRI Configuration

 

The yate wpchan configuration file is located at yate/conf.d/wpchan.conf. A sample file, called wpchan.conf.sample

Copy the sample file to wpchan.conf and add the following lines in the [span N] section, where N is your span number.

wpchan.conf
------------- cut -------------------

buflen=160

dumpevents=no
dtmfinband=no
dtmfdetect=yes

bitswap=no ; (a bad value here produces white noise when playing a sound)

[span 1]
