2.10.4 Notes on the planning of networked HiPath 3000 systems
with the network-wide roaming feature
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 2.10.3.
If using the "network-wide roaming" feature, you must make sure that different systems with
identical DECT IDs do not have overlapping radio ranges. Handsets treat networked systems
with identical DECT IDs as a single system.
When hops overlap in systems with identical DECT IDs, handsets start to perform unintentional
network-wide handover attempts which result in call cleardown.
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. The network-wide roaming feature is not supported in this
case.
The following diagrams show three different showing HiPath 3000 system networking scenarios.
Scenario 1: Incorrect DECT Configuration of Networked HiPath 3000 Systems
Identical DECT IDs and overlapping radio areas result in incorrect handover causing a breakdown
in communication.
PSTN
HiPath 3000 system 1
DECT ID = 4711
Networking (S 0 , S 2M , IP)
HiPath 3000 system 2
