Hello List
I'm trying to make my openbsc installation work in half rate mode but
I'm facing some errors.
I'm wondering if someone could provide me with more info or help me to
configure openbsc.
I have changed in openbsc.cfg the timeslots 2 to 7 from
phys_chan_config TCH/F into phys_chan_config TCH/H also I have tested
changing neci bit and change audio codecs but no luck.
Am I missed something? Is there any way to run osmo-nitb with gsmtap?
openbsc.cfg is attached
Thanks in advance.

Thanks for the immediate response.
Is your answer based on hands-on experience, feedback from other
developers/users or something else?
In the nanoGSM® EDGE 900 datasheet is not mentioned the TCH/H support,
but the nanoGSM® EDGE 1800 model seems to support it.
Do you believe that the 1800 model could work?
Also I noticed in the OpenBSC wiki that TCH/H is not implemented in
osmo-nitb but only in osmo-bsc, is this information correct?
Thanks for your time.

to make my openbsc installation work in half rate mode but
I don't think
nanoBTS support HR codec at all ...

there are several
reasons why TCH/H is not currently working with
osmo-nitb. i plan to make it work soon, but it still requires BTS to
support it.

TCH/H != HR
The EDGE models do support AMR-HR. But that's different from HR. And
not supported by osmo-nitb currently.

support HR speech codec
and in osmo-bsc TCH/H is supported unlike osmo-nitb?
and if i write code in osmo-nitb that support TCH/H i will have 14
simulate calls in my setup?
are there any guidelines for new openBSC developers or can someone provide me with some
highlights about porting TCH/H from osmo-bsc to osmo-nitb?
Thanks again for your time.

hi,
there are several things that need to be done to support TCH/H as well
as AMR codec at osmo-nitb. as i said before, i am working on it.
regards,
andreas
