LCR VS. Toll Restriction
LCR is not intended
to be an alternative
to toll
restriction
nor is toll restriction
intended
to be
a a&mate
to LCR
In fact they both work best
when
programmed
together.
Toll restriction
provides
the dk&ng
privileges
that stations
are
allowed
and LCR provides
the muting
of calls
onto the proper type of lines. LCR can enhance
toll restriction
in that LCR provides
a 'Store
and Forward'
operation
that allows the system
to zanalpe the digits being dialed before a trunk
is seized.
This prevents
users from by-passing
toll restriction
by taking
advantage
of the time
it takes for a central
offfce line to provide
dial
tone.
Because
of this it is recommended
that
LCR be considered
when toll restrfction
is de-
sired.
