Steven,

Some early implementations of SS7 link hardware could not receive
at anything close to 1 Erlang and would generate SIB at regular
inteverals to throttle receive traffic down to a dribble while
still maintaining conformance with specifications.  A way to keep
these poor implementations out of the network was to impose a
network-specific requirement that no signalling link generate SIB.
Some specifications never removed the requirement over the years.
