Steps
The 4096 Hybrid
Key Telephone
System offers
a flexible
means
of applying
toll restriction
to
stations
or individuals.
Dialing
privileges
(or
toll restriction)
is determined
through
assign-
ment
of station
and CO line Class Of Servfce
(COS).
Several types of restriction
can be de-
rived
simply
by programmin
g cos
assign-
ments
and CO tie
access to stations.
This
may,
in some cases, be all that is necessary.
However,
when a more complex
or specific type
of restriction
is desired
the system
offers two
allow
and
two
deny
tables
along
with
four
special
tables.
These
tables
can
be pro-
grammed
in a variety
of ways to handle
appli-
cations
that
are
straight
forward
or
applications
that
require
a more complex
ar-
rangement.
The
allow
and
deny
tables
are assigned
to
stations
based on their station
Class of Service
(COS) assignment.
The Station
(COSI interacts
with
CO Line
COS assignments
to provide
several di!Terent
types of dialtng
prklleges
(Re-
fer to CO/Station
COS matrix
below).
The Allow
and
Deny
tables
allow
entries
of
either general
or specifk
allow and deny codes
such as allowing
all [l-800]
type calls, and/or
denying
all Ill+
or (01~ calls.
The allow and
deny tables allow a maximum
of eight digits to
be entered
as allow or deny digits. This allows
for entry
of certain
area codes or of&e
codes
or a combination
of area code plus office code
that can specifically
be allowed
or denied.
For
example
the code [l 555-12121
may be entered
in the deny table to deny local toll Information
calls.
Each allow table contains
twenty
(20)
bins for entry of allow codes.
'Ihe deny tables
allow for ten (10) entries of deny codes. in each
table.
The
following
rules
should
be remembered
when
setting
up the Al.Iow/Deny
tables Prefer
to Table 750- 1).
1.
2.
3.
4.
If both
tables
(allow and deny) have no
entries,
no restriction
IS applied.
If entries
are made in the allow table and
only there.
then
only those numbers
are
allowed.
All other dialing
is denied.
If entries
are made in the deny table and
only there.
then only those numbers
are
denied.
All other dialing
is allowed.
If there are entries in both allow and deny
tables, the allow table is searched first and
if amatch
is found,
it Is allowed.
Ifa match
is not found,
the deny table is searched
and if a match
is found
there, the call is
denied.
lf the number
does not match
an
entry in either
table. it is allowed.
