Hello fellow Osmocomers,
I just recently came across and watched Harald's ODC 2018 presentation
about Ericsson RBS 6000. The part that intrigued me: Harald said in
that year that this hardware was available quite inexpensively and
plentifully; he said that a DUG10+RUG pair could be had for around
300 EUR in that year.
My question to the community: what is the current situation 6 y later?
Is there still any above-zero supply of either DUG10+RUG or DUG20+RUS
surplus hardware? If a nonzero supply does exist, what is the typical
price these days?
In that 2018 presentation Harald also mentioned that the successor to
DUG20 was DUS31/DUS41, and that those DUS units (which support GSM,
WCDMA and LTE all in one box) have integrated SIU02 equivalent instead
of native E1 interfaces. Hence question: has anyone in Osmocom cracked
the E1-over-IP protocol spoken by SIU02 and its later incarnations,
allowing Osmocom CNI to drive the GSM part of DUS31 etc, or is such
operation beyond our current community capabilities?
There are rumors going around that T-Mobile USA may be shutting down
some Ericsson 2G equipment (though I still never got any clear answers
as to what equipment it might be, if any), hence I am trying to brush
up on my knowledge of this platform.
