2.4 Network Requirement
Voice connections only work properly over IP networks if the IP network satisfies
all general VoIP network requirements in terms of delay, loss and guaranteed
quality of service features.
The following conditions should also be assured for the DECT IP base stations
and the DECT Manager & Integrator in the IP network:
•
they have to be part of the same Ethernet segment, a layer-3 routing via
an IP router is not supported,
•
no devices use the Network Address Translation (NAT) Ethernet segment
•
Minimum 2 priority classes acc. to IEEE 802.1 p/q in the IP Network
possible
•
Use of 100 Mbps full duplex for all switched LAN ports
•
as the solution operates with standard IP addresses, these must be freely
available in the IP network.
Failure to satisfy these conditions can result in delays in the IP network. This
leads to synchronization and voice quality problems in the DECT handsets.
