I'm not familiar with it, but if you say so.

It all looks good to me. Two minor notes:

- the pcu config once needed 'two-phase-access' to function reliably, but this
  is no longer needed.

- you seem to be running an old version of the ggsn. The new one is called
  osmo-ggsn with a config file style and vty interface like the other osmo
  programs. However, this should not affect your downlink throughput.

- you also seem to run osmo-nitb, we have moved to separate programs, being
  osmo-hlr, osmo-msc and osmo-bsc. Refer to
  This should, however, not affect your downlink throughput, either.

So yeah, sorry, but I have nothing of weight to add. Maybe someone else here
has deeper knowledge of EGPRS and SDR based BTS?
