This table is for allocating a selection of bundles for external lines to internal
lines (analogue and system) subscribers. If an internal subscriber chooses the
service Access to an external line and the LCR is not activated or they are
returning from it because a different, cheaper route was not found, then for calling
to the VTS the priority external line is first used and if the first choice is not
available then the first free external line selected from the bundle. The priority line
can even be from a disallowed bundle.
If, for instance, we imagine 4 varying privileged groups of subscribers from
the standpoint of their choices for a free external line (ignoring the LCR). The first
circuit will be 2 internal lines to the flat of the building administrator, the second
circuit to the director with an assistant and a company fax, the third circuit will be 4
traders and the fourth circuit the other employees with the lowest set selection for
an external line. In order to meet these requirements we split up the external lines
(except external lines allocated to GSM phones) into, for instance, 4 bundles.
Bundle 1 has 1 external line
– for the building administrator‟s flat. External lines 2
and 3
– the directorate – are assigned to bundle 2. The external lines 4 and 5 are in
bundle 3 and the last external lines, 6, 7 and 8 are assigned to bundle 7.
Afterwards for starting up an external line we can assign the internal links from the
administrator‟s flat just to bundle 1. Like this no one else can get on this external
link. For the director, assistant and fax we assign bundles 2 and 7 for starting up to
the VTS. Like this two calls can be made simultaneously from the directorate on the
private lines and other calls (faxing, other external conference calls , …) choose
one of the free external lines
from the last bundle, 7. Similarly the traders‟ lines can
be chosen from bundles 3 and 7 for external calls. The other employees can only
use the last bundle, 7. In this case bundle 7 not only serves the group “other
employees” but also as a reserve for the traders and the directorate with a fax. This
selection can be enriched by setting the priorities for the internal and external lines.
For the priorities the valid principle is that an internal subscriber must have the
same or higher priority than an external line so that it can be assigned to him.
