D210E with echo cancellation

Hi

this is my first attempt to install D210E with echo cancellation module built in.

i refer to your example

www.openvox.com.cn/bbs/viewtopic.php?t=5...a245de3bdc1eaec6a481

so far seems good, and i just need you to verify that the echo cancellation is properly loaded.

/etc/dahdi/sysconfig.conf

echocanceller=mg2,1-15,17-31

hello openvox
can you reply my last message?

i need your confirmation before live installation

Regards

HI,
First,you should modify /etc/dahdi/system.conf and comment echocanceller as below:

---

[font=宋体]bchan=1-15,17-31[/font]

[font=宋体]dchan=16[/font]
[font=宋体]#echocanceller=mg2,1-15,17-31[/font]

......
[font=宋体]bchan=94-108,110-124[/font]
[font=宋体]dchan=109[/font]

[font=宋体]#echocanceller=mg2,94-108,110-124 [/font]

---

You can run:
dmesg |grep VPM
and if you find like the following it means EC module has been detected.

---

VPM450: echo cancellation for 128 channels
VPM450: hardware DTMF disabled.
VPM450: Present and operational servicing 4 span(s)

---

Then you make a call if you find the EC state is ON it means EC module is working

---

Echo Cancellation:
128 taps
currently ON

---

Would you please let me know where (in which file) or what CLI command shall I use to get the above show? By the way, I'm using DE115E.Thanks in advance.

HI,
If you make a call via channel 1,please input "dahdi show channel 1" and you can find the EC state.
