[asterisk-r2] E1/R2 on TE121B Digium Card

Sun Apr 19 21:20:57 CDT 2009

Hello all,

Our Asterisk + OpenR2 setup still have problems.
we inserted a loopback plug in our TE121B digium card (with DAHDI) and troubleshoot it.
we got a GREEN light and no errors in running the test commands.
but when inserting the E1/R2 digital line,  it is always a RED light.

i am thinking that the problem would be the line itself.
and right now we are contacting our telco.

does having a GREEN light in inserting the loopback plug means
our setup in the asterisk server (asterisk packages and digium card) is ok?

if you have this experience, please share how to solve this problem.

thank you very much.

Hello Carlos,
Thanks for the reply.
Can you give me some refererences or details of your configurations?

Here is my current setup.
Digium Card: TE121B
Digital Line:  E1/R2 line with a G.703(RJ45) interface (European standard)
OS: RedHat 5.2
Zaptel: zaptel-1.4.12.1
OpenR2: openr2-1.1.0
Asterisk: http://svn.digium.com/svn/asterisk/team/moy/mfcr2-1.4

We followed the instructions from this documentation.
http://openr2.googlecode.com/files/openr2-guide-0.1.pdf

Here is my /etc/zaptel.conf
span=1,1,0,cas,hdb3
cas=1-15:1101
dchan=16
cas=17-31:1101
defaultzone=ph
loadzone=ph

/etc/asterisk/zapata.conf
[channels]
context=incoming
signalling=mfcr2
mfcr2_variant=ph
mfcr2_max_ani=12
mfcr2_max_dnis=18
mfcr2_category=national_subscriber
group=1
channel=>1-15,17-31

Base on that setup, when I check the log I found this error also.
Apr 17 23:37:27] WARNING[16763] pbx.c: Already have an application 'ZapAcceptR2Call'
[Apr 17 23:37:27] ERROR[16763] chan_dahdi.c: Cannot create OpenR2 protocol context.
[Apr 17 23:37:27] ERROR[16763] chan_dahdi.c: Unable to register channel '1-15'

What do you think is the cause of this problem?
Thank You very much.

Well, I have a TE121 working in this moment with MFC R2 signalling and Asterisk + OpenR2, that means this setup is workable.  Don't dude to ask if you need something, bye.

Hello all,

I am configuring an Asterisk Server.  I use TE121B Digium card and an E1/R2 line.
Is this setup workable?  I am using openR2 also.

thanks
