When configuring an SI5ter in the nitb config like this:

network
 bts 0
  neighbor-list mode manual-si5
  si5 neighbor-list add arfcn 0
  si5 neighbor-list add arfcn 1
  si5 neighbor-list add arfcn 2
  si5 neighbor-list add arfcn 3
  si5 neighbor-list add arfcn 4
  si5 neighbor-list add arfcn 5
  si5 neighbor-list add arfcn 580
  si5 neighbor-list add arfcn 1023

the SI5ter is passed to the BTS:

but using GSMTAP shows that the SI5ter is never sent to the MS.
