 The point-codes are configurable, and default to OsmoBSC's local point-code
 0.23.3 (187), and remote SMLC point-code 0.23.6 (190).
 
+Typically, multiple BSCs connect to the same SMLC, so that each BSC needs to
+have a distinct point-code, while the SMLC has a single, fixed point-code.

 To configure a different remote SMLC point-code, first configure an arbitrarily
 named SCCP address in the `cs7` address book, and then apply that to the
 `smlc-addr` configuration:

-Similarly, OsmoBSC's local point-code on the Lb-interface is configured by the

+For the BSC side, it suffices to configure a point-code in the `cs7` section,
+so that the BSC typically uses the same point-code on A and Lb interfaces. In

+It is also possible to configure a distinct BSC's point-code on Lb, using the
