NOTE:
area codes are all considered local. You can, however, program an ATM node to require
ten-digit dialing on all local calls. This makes ten-digit dialing optional for all dual chas-
sis residing in the home area code. Metropolitan areas with overlapping area codes
would, however, have to dial ten digits for home area code calls.
•
Toll Digit Allowed On Toll Local Calls: This option applies only if the area and office
codes overlap. Callers in the site's area code usually dial a 1 when placing a call within
the local area code(s).
•
Toll Digit Required On Toll Long Distance Calls: This option applies only if the area
and office codes overlap. Callers in the site's area code must dial a 1 when placing a
call outside of the local area code(s).
10.153The database requires that the programmer enter a "home" area code for the system
site. It also allows up to 16 home area codes for non-toll calling. The system refers to these
area codes for toll restriction and call cost.
Absorbed Digits
10.154Trunk groups that are subject to toll restriction can be programmed to "absorb" (ignore)
the first digit(s) so that the digits dialed are handled by the system just as they would be by the
local telephone company [network provider in Europe] or PBX to which the system is con-
nected. There are two applications for this capability: PBX installations and installations in
areas where part of the local office code is absorbed by the central office (CO) or local
exchange. Trunk groups that connect to outside trunks in PBX installations are referred to as
"PBX trunk groups." Trunk groups that use trunks for which the CO absorbs part of the local
office code are referred to as "local trunk groups."
10.155When an Inter-Tel system is installed behind a PBX, users must dial special PBX codes
to select the CO trunks. The system trunk group that is used for PBX trunk access must be pro-
grammed to absorb PBX digits. The PBX access codes are then programmed as the absorbed
digit patterns for that PBX trunk group. Up to 50 absorbed digit patterns are allowed, with a
maximum of 48 digits in each.
10.156When a PBX trunk group is used and an absorbed digit string is not dialed, the system
behaves as though the trunk group is "not subject to toll restriction" and does not perform toll
restriction and call cost functions. The call is considered to be an internal PBX call; it is
allowed no matter what digits are dialed. The call cost rate is "PBX," and the call is designated
as free (000) in the SMDR report.
10.157When a PBX trunk group is used and an absorbed digit string is dialed, the system
absorbs the PBX access code and behaves as though the trunk group is "subject to toll restric-
tion," using the remaining digits for toll restriction and call cost processing. When the Redial,
Speed Dial, or Call Forward features are used, the system automatically inserts a short pause
after the absorbed digit string to provide for the delay that occurs while a trunk is seized.
10.158In some rural areas, specific digits (dialed as all or part of the local exchange) are
absorbed by the central office [local exchange], thus reducing the number of digits required to
dial local calls. These digits may also be "repeatable." That is, they are absorbed if dialed more
than once. To determine if a central office [local exchange] absorbs digits and whether the dig-
its are repeatable, contact the telephone company [network provider].
