Installation manual
IVX 128 Function 2: CO lines
E.7
Function 22: Access codes/toll restriction
Function 221: Centrex/PBX access code
If the system is to be used behind Centrex or another PBX, you must list the
dial access code
used
to gain access to a CO line from Centrex or the PBX, so that toll restriction can ignore the access
code digit(s). Users must dial the access code after accessing a line by
either
:
(a.) Dialing
9
,
8
,
71
,
72
,
73
,
74
,
75
or
76
.
or
(b.) Pressing a line key (if programmed)
The access code can be one or two digits —
e. g.,
9, 81,
etc.
— and must be programmed for each
line group.
Default:
0
.
Note:
You must set the flash duration (Function 151; see page D.2) for the requirements of the
host switch.
Function 222: Toll restriction exception tables
The system’s toll restriction is based on outbound calls being defined as either
toll calls
(i.e.,
calls
in the
deny table)
or
non-toll calls
(calls in the
allow table
). Four tables exist for this purpose:
1.
Allow exception table
(programmable).
Default:
No entries.
2.
Deny exception table
(programmable).
Default:
No entries.
A number listed in the
allow
exception table —
e.g.
, a branch office or vendor’s location — will be
allowed
to all stations, regardless of how they’re set in Function 32 (see page F.5). Conversely, a
number listed in the
deny
exception table (e.g., a “1-900” number) will be
denied
to all stations.
3.
Fixed allow table
(not programmable).
Default:
1800, 1888, 1877, 1866, 1855, 1844, 1833
and
1822
.
4.
Fixed deny table
(not programmable).
Default:
976, 1976, 1xxx976, 900, 1900, 1xxx900, 555, 1555, 1xxx555, 0, 10, 411, 1411
and
10+-digit restriction.
As part of extension feature authorization (Function 32; see page F.5), each station is programmed
to be allowed or denied toll calls by following the fixed tables when they are programmed with an “N,”
as well as following the allow and deny exception tables (
i.e.
, overriding the fixed tables). All stations
that have been assigned access to a line group can make non-toll calls.
To program the allow and deny exception tables:
1.
Enter the numbers for either table, separating each number by
#
.
Example:
For “1-900,” enter
1 9 0 0 #.
Note:
Press
MUTE/DND
to insert a
“
wild card” digit.
A “wild card” digit is needed only when followed by more numbers;
e.g.
, to allow/deny
1-555
, enter just
1 5 5 5 #
— however, to allow/deny 1-all area codes and 555, enter
1 X X X 5 5 5 #
(where X indicates a pressing of
MUTE/DND
).
Warning:
Do
not
include IVX’s line access codes (
9, 8
or
71
–
76
) in
any
of the toll restriction entries.
