Kuldeep,

In the case that the RK is based on SI value, ASP Inactive is the correct
message.  In the case that RK is based on PC, user part flow control is
the responsibility of the ASP (i.e. it could send UPU (the SS7 message, not
the M3UA SNMM message) to the other end, or an equivalent user part message
(e.g. Subsystem Prohibited).
