Hi Andreas.

As you may have noticed, we have reached a point with L1 and 'layer23' where
your L3 work could actually be testea, given the following preconditions:

 * BTS with no frequency hopping, no encryption
 * combined CCCH (with SDCCH/4 on TRX0)

the 'layer23' program already sends a fake LOC UPD REQ to the BTS,
just to test if the transmit path is working.

I didn't want to continue at this point, as there are many other tasks that
desperately need attention - but also since you have been starting with work on
MM procedures like location updating by yourself.

If you configure a BS-11 or nanoBTS with OpenBSC to use a combined CCCH,
you should be able to develop your code and immediately test it on the 'live'
system.

I would really appreciate if you could start a git branch with your code added
to the 'layer23' program - even if it doesn't compile yet and is incomplete.

This way everybody is aware of what you are doing and we don't get any
duplicate work.

Cheers,
	Harald
