3 - 7 TRS (Toll restrictian svstem)
mode
This is to set toll restriction
for a telephone.
There are 7 types of setting for
each outside
line connected
to
the system in the case
of
each telephone.
In that restrictions can be set for daytime and
nighttime separately, it is also possible to
control expensive telephone charges.
Toll restriction implemented here is done by
determining whether or not the call is
allowed depending on the number dialed by
means of the code table in the main memory
(toll number- area number- telephone
number).
Below is shown the structure of a simple TRS
system.
