Types of SIP DECT conﬁguration

You can implement SIP DECT in various system configurations to

accommodate your needs. The most common SIP DECT configurations

are as follows:

•

Basic (or Simple) Configuration

• Routed Head Quarter Configuration

•

Branch Office Configuration

• Routed Head Quarter Configuration with Branch Office

• Multi Site Mobility Network Configuration

•

Basic (or Simple) Configuration

In Basic Configuration all DAPs are in the same subnet that is

based on one or more IP switches. IP multicast must be able to

occur between all DAPs. The configuration supports seamless

handover between all DAPs. For an illustration of a simple SIP DECT

configuration, see Figure 5 "Simple SIP DECT network configuration"

(page 28).

• Routed Head Quarter configuration

Routed Head Quarter Configuration is used for a Large Campus

network that is split into several subnets. In this configuration DAPs

belong to various subnets and behave as one large SIP DECT system

with the full support of seamless handover. IP multicast must be able

to occur between all DAPs in the Campus network, through IP switches

and the IP routers that connect the various subnets. For an illustration
