correct.
Are there any options to do so?Any suggestion would be
appreciated.
Unfortuantely not. We know several people who have developed GSUP to MAP
translators, but unfortunately none of those users was willing to release
their software as open source, like we do in osmocom. Until people
with a need for TCAP/MAP in Osmocom networks will contribute the related
code, it will not
A side question: is GSUP the only custom protocol used
in osmocom gsm
network?all other interactions are based on 3GPP?
There are some custom interfaces, for example the pcu_sock between osmo-bts and osmo-pcu,
or the MNCC interfae between osmo-msc and osmo-sip-connector.
But the A, Gb, Lb, Iu, Gp, etc. interfaces are all as specified by 3GPP.
Abis is modified to work over IP (not covered by 3GPP specs even today), see
