274 Call Routing Part 2
5.2.1.2 Call from the Private Leased-Line Network
In the private leased-line network, direct dialling plans are set up only if calls are
to be routed to their destinations via call distribution elements in order to benefit
from the advantages of the flexible routing properties of call distribution elements
(see "Call Distribution Element (CDE)", page 226).
Call distribution elements can be dialled up directly if they have been allocated a
phone number in the numbering plan and if they exist as PISN subscribers in the
other PINXs. However, without a direct dialling plan it is more difficult to achieve
a numbering that matches.
Tab. 2.28: Flexible routing with and without direct dialling plan; difference in numbering
Calls from the private leased-line network do not have any DDI numbers. If you
set up a separate direct dialling plan, however, these numbers can also be han-
dled in the same way as DDI numbers.
Tip:
Only individual numbers can be organized via a direct dialling plan; the
others are organized directly in a numbering plan.
