Description
The OsmoSGSN user manual is less complete than some of the other user manuals we have in the osmo-gsm-manuals project. Let's try to change that.

The manual seems not to document how the ACL works. It only says that there is an ACL (chapter 9.2), but not how to use it.

Reading through the manual now and came across a couple questions/remarks:
- Ch. 4.2.4 LLC Implementation says there is no header/data compression. I think the compression dexter implemented (RFC1144 and V.42bis) is meant here even though it talks about IP header compression in the overview, but TCP/IP header compression in ch. 9.5.
- LLC encryption is now supported since the SGSN can connect to the HLR. It seems only GEA3 and GEA4 are implemented in libosmocore.
- In the limitations only paging coordination and SMS over PS remain?
So far I went through the overview and running chapters, going to look at configuring and Gb next.
