Description Of System Features
IMI 66-097
Toll Restriction - Flexible
Flexible toll restriction can be programmed to prohibit
some or all stations from calling a wide range of num-
ber combinations while allowing specific exceptions.
Restrictions are specified by up to four entries on a
deny table while exceptions are specified by up to four
entries on an allow table. Allow entries will always
override deny entries. Up to eight digits are permitted
for each entry. A “match anything” digit (# symbol) can
be included as pari of an entry to represent any digit
from 1 to 0. This is used to deny or allow a range of
numbers with one entry. A separate pre-programmed
1+800 allow table permits this dialing feature to be
selected regardless of any restrictions which may be
specified. The dialing of 911 and 1+911 is always al-
lowed.
Once programmed, flexible toll restriction is assigned
on a per line/per station basis. In addition to flexible
restriction, or as an alternative to it, stations can be
restricted with l/O call restriction assignment. When
l/O call restriction is selected, 1+ 7 digit dialing can be
allowed if desired. Either system or administration
programming is used to specify the deny and allow
entries and assign the restriction to line and station.
Tone Or Voice Signalling
(Intercom)
Intercom calls can be tone signalled or voice signalled
as desired. The tone signalled intercom call must be
answered by lifting the handset. The voice signalled
intercom call can be responded to in a handsfree man-
ner. The class of service programming determines
which signalling method is employed as the primary
method when an intercom call is made. The alternate
method is available through user action at the station.
Intercom call progress is marked by special tone sig-
nals. The system or administration programming
determines which type of intercom signalling is first op-
tion signalling for the system. Also refer to the discus-
sions titled Intercom Call Progress Tones and Voice
Announce Blocking.
Voice Announce Blocking
This feature allows the user to block voice announced
intercom signalling by dialing a special code. This fea-
ture, when enabled, also blocks the reception of a
SOHVA call.
Zone Paglng (Through Station Speakers)
Zone paging allows groups of stations to receive an-
nouncements through the station speakers. The
programming can enable zone paging in up to three
different zones. A station can be programmed to only
receive announcements or programmed to originate
announcements as well. Each station can be
programmed to be in any or all zones for both receiv-
ing and originating announcements. The ability of
each station to originate and/or receive a page, and
the arrangement of the paging into different zones are
controlled by system or administration programming.
Also, refer to the discussion titled AI/-Call Paging (via
Station Speakers).
