+-- WORK IN PROGRESS --
+
+This is an incomplete collection of call graphs between MSC and Osmo-BSC,
+partly including Osmo-BTS. These traces helped understanding the separation of
+the BSC part from Osmo-NITB. The aim: obtain a clearly separated "A" interface
+towards the BSC, and have an Iu-CS interface to operate with HNB-GW and hNodeB.
+The working title for the result is Osmo-CSCN (Circuit Switched Core Network),
+combining an MSC with various other core network components, but without the
+BSC parts.
