wired ISDN + analog telephony (jolly, laforge)
- have ISDN / analog lines from datenklos
- have it connected to eventphone / sip
- need an addition vlan? coordination.
how many sim cards to order (lynxis)
- lead time issues: 1k probably not a problem. 10k need more lead time.
- What do we want to put on the SIM card?
mobile network code
- used unofficial until now
- now we have conflict because our old one (262 42) was taken
- Can roam into our new private network
- But if UE tries to regsiter onto 262 42 (now acquired by vodafone), users
will get a permanant rejection and they won't even try to roam into our network
anymore.
- experimental prefix 7x
- buy one? Probably not, because ITU requires it to be a public network
- 999 (international prefix for private networks) [Link to BNetzA

- Do we care about the old SIM cards?
- We have ~20k in our old HLR
- OTA or have someone reprogramming the SIM cards in the GSM tent
- The industry is moving to 2FF or even 4FF. Need more process to order
full form-factor cards.
Seems we go for MCC 999 and see if 42 is free.
Hopefully there aren't any problems with 999 MCC.
- bibor: !action! ask the BNetzA to ask for the list.
- form for that:

### Band licensing
* bnetza might give us 5Mhz in 850 Mhz, 1900 Mhz
* 2600 Mhz might be easy obtainable from operators since nobody is using it out
there
