5.33.2. Service Information 
The 'T-Reference point' feature is for all systems equipped
with LTUCC/LTUCE/SCC boards. All other systems will respond to any attempt

Within the system various subsytems are resonsible for enabling the
Loss Plan
A.M. is responsible for configuration and definition of the Loss Plan
and to specify in which country the sytem is operating. Administration
is also responsible for defining the loss pair values for initialisation
of boards
D.B. is resonsible for DBARs to access the defined loss plans
C.P has the resonsibility of deciding when an attenuation value has
to be sent to the LTUCE/LTUCX for a given timeslot duriong a call (The
LTUC/LTUCX applies the attenuation to the timeslot
Dependability (PIT) is resonsible for downloading data to the boards
(existing function of parameter COFIDX in AMO's SBCSU and TACSU
)
The T Reference Point Feature is the basis for the loss plan implementation
for the U.S market the U.S. values being integrated into the existing
