As suggested by these examples, a great deal of flexibility exists within
the system, and groups of features can be easily set in place for the
various extensions.
7.07 Paragraph 7.19 details a particular case where an extension is
fully restricted, and is an example of a Class of Service incor-
porating restrictions rather than access to features.
Access Code Assignments
7.08 Access codes are allotted for desired features and programmed
into the system. These codes may consist of one, two, three or
four digits and must be unique; i.e., they must not conflict with any
other numbers allotted within the system. (Note the exceptions for
override, callback busy.) Extensions may have the capability of dialing
these codes subject to whether their Class of Service incorporates
these particular features. Typical access code examples include such
features as Paging and Executive Busy Override.
Extensions
7.09 An extension is
field and, via the cable between it and the shelf backplane, to a
port within the equipment shelf. The port is identified with a particular
equipment number and, by means of the Extension program, is given ,,
an extension number and linked to the required Class of Service. It is \
then allowed or denied toll access, assigned an appropriate Busy Lamp
on the Attendant Console and linked to a Pickup Group. Changes, such
as the allotment of a new extension number or additional features
(including restrictions), are effected by simple keying sequences from
the Attendant (or Maintenance) Console. The console must be in the
programming mode.
Extension Hunt Groups
7.10 Hunt Groups are programmed with their own master access
codes and with the equipment number (port) of each extension
that is to be part of the particular group. This master number must be
unique within the system. It cannot be one of the extension numbers
of the group. This method is required to ensure that the Call Forward-
ing and Callback features are available even when an extension is part
of a Hunt Group. Use of a master number also eliminates any conflict
between hunting and forwarding.
7.11 Hunt Groups can be arranged to be of the terminal, circular or
secretarial type, as detailed hereunder: Terminal hunting results
in the group being accessed successively from the first to last exten-
sions programmed into the group, with the first nonbusy extension in
the sequence being rung. Circular hunting starts at the last extension
which was reached and hunts over all extensions until the first free
extension is reached. Secretarial hunting is similar to Terminal hunting, ."
with the additional facility that the last number in the group is corn-
mon to two or more groups. It should be noted that each extension is
connected from the building cross-connect
