11.6 Planning Notes for Networked HiPath 3000 Systems Featuring
Network-Wide Roaming
The demand for additional B channels for fixed connection paths (CorNet NQ) must be taken
into account for the system-wide extension connections described in Section 11.5.
If the "Network-wide roaming" feature is used, please ensure that there is no overlapping in the
radio areas of individual systems with identical DECT IDs. Networked systems with identical
DECT IDs are viewed as a single system by the handset.
If the radio areas of systems with identical DECT IDs overlap, mobile telephones inadvertently
try to perform network wide handover, which results in communication breakdown.
If networking is required for systems in which the individual radio fields overlap (for example,
to increase capacity limits or through decentralized installation), different DECT IDs must be
configured in the individual systems. Network-wide roaming does not apply in this case.
The following describes three different scenarios for networked HiPath 3000 systems.
Scenario 1: Incorrect DECT Configuration when Networking HiPath 3000 Systems
Identical DECT IDs and overlapping radio areas result in incorrect handover causing a break-
down in communication.
