Cellular Network Infrastructure - Bug #4069: Implement IPA PING/PONG mechanism everywhere
Implement IPA PING/PONG mechanism on RSL and OML
Let's make sure the RSL and OML links use the IPA PING/PONG mechanism to the BTSs and disconnect if no PONG is received. the interval and timeout should ideally be user(vty)-configurable. It might be that the actual code has to reside in libosmo-abis, not in OsmoBSC itself. Keep in mind that classic E1 BTSs don't have IPA or TCP.
