TABLE
TABLE
A special 'Don't
Care" ('D') character
may be
entered
as a digit to either allow or deny any
digit dialed in that digit sequence.
For example
a code [ 1 'D" 01 and [l 'D" 11 may be entered
tn the deny table whtch would
allow local long
distance
calls (numbers
dialed
with
a 1 fol-
lowed by a seven digit local number).
but would
deny long distance
calls (numbers
dialed with
a 1 followed
by an area code).
The 4096
system
also offers four
(4) special
tables
that
can be referenced
from wlthln
the
two aIlow tables.
Three
of the special
tables
can be assigned
to specific
area codes that
require
further
toll restriction
definition.
The
fourth
special
table
is reserved
for use as a
home
area
code table
(numbers
withln
the
same area code as the site where the system is
fnstaJled).
l%is provides
expanded
ability
to
apply toll restriction
on numbers
that are di-
aled within
an area code.
Each special table
will allow up to (800) entries
(200-999).
This
offers the ability
to allow every office code on
an individual
basis

RELATED
ITEMS TO TOLC RE-
STRICTION
A
CO/PBXLines
When CO lines are marked
as PEN lines (Refer
to CO line programming
Sec. 720)
the system
wi.lI first check the PE3X code table (Refer to sec.
710.17)
for a valid match.
If the first digits
dialed do not match
the entries in the PEX code
table the call is considered
an attempt
to call
another
PBX extension
and no toll restriction
is applied.
If the first digits dialed are found
in
the PEX code table
then
toll restriction
will
start with the next dfaled digit.
B.
Forced
Account
Codes
The system
can optionally
force the use of
amount
codes on ail restricted
calls.
When
forced account
codes are enabled
(Refer to Sec.
710.19)
an account
code must
be entered
to
place a call that is otherwise
restricted
through
toil restriction.
By entering
an account
code
the stations
effective
class of setice
becomes
that equal to class of senlce
1 (unrestrictedl.
When
account
codes are forced
on a system
wide basis selected users may be instructed
on
how to enter
account
codes from
any statfon
and
be allowed
to dial unrestricted
from
a
station
that may othexwise
be restricted.
Use
of account
codes in this manner,
as a traveling
class-of-service,
is however
not controlled
by
the system.
Any station
user with knowledge
of how to enter
account
codes to override
a
stations
tolI restriction
will be allowed
to do so.
C. SLT
DTMY Receivers
When single line telephones
are con.ne&d
to
the 4096 system and toll restriction
is enabled
the system DTMF receivers located
on the APL
board
will monitor
the call for a programmed
period
of time (Refer to Sec. 710.35,
SLT Re-
ceiver Timer).
WhiIe
the DTMF
receiver
is
monitoring
the digits being dialed.
by a single
line telephone,
it is considered
busy and not
available
for monitoring
another
SLT attempt-
ing to dial
When all DTMF receivers
are busy,
an SLT attempting
to go off-hook
will not re-
ceive dial tone until a receiver is available.
The
system
has up to six (6) DTMF receivers
(two
(2) standard
on the APL and four (4) optional
on the SLU) for monitoring
SLT dialing.
If a
system
has heavy
SLT usage toll restriction
may inhibit
dialtng
by SLT stations.
Two op-
tions are available
to help alleviate
t&s prob-
lem:
1) shorten
the
SLT receiver
timer&e
sectton 710.35).
This will f+ee up DTTvlF receiv-
ers faster,
however,
may not provide
the de-
sired
toll
restriction
for SLT stations:
2)
Enable
LCR and force LCR on SLT stations.
When
the LCR data base is set up the three
dlglt table
allows
for entry
of the number
of
digits
to be expected.
When
a SLT dials the
appropriate
number
of d.igits LCR will release
the DTMF
receiver
and then
be available
for
another
SLT call.
