System configuration
addresses of the DAP or DAPs using this subnet mask. If the IP addresses are in various
subnets according to this mask, the DAP or DAPs are supposed to be in a branch office.
If the IP addresses are in the same aggregated subnet according to this mask, the system
assumes that the IP addresses are in the same subnet.
The term aggregated means that the subnet consists of smaller subnets connected over
a router, but according to the subnet mask, all behave as one subnet. This applies to the
Routed Head Quarter network solution without branch offices.
Routed Head Quarter configuration implies that various subnets are connected through
one or more routers. The subnets in the network are part of one company network.
To create a Routed Head Quarter configuration, you must configure the network
components, such as the switches and the routers, for VoIP and IP multicast. Also, the
network must support IP multicast between all network components used for the SIP
DECT system.
Routed Head Configuration is the same as Simple configuration, but includes one
additional step. For information, see
Configure Routed Head Quarter
Follow these procedures to choose a system configuration and configure Routed Head
Quarter.
Choosing system configuration
1. If you were referred to this procedure from
2. Select the SIP DECT system that you are running. Click System Configuration.
3. Choose Routed Head Quarter Configuration for System configuration.
4. Enter a Time To Live Value greater than 1 to have the Router forward multicast
5. Calculate and enter the Aggregated Subnet mask.
6. Perform one of the following steps:

packages.
The Aggregated subnet mask is the subnet mask for the DAPs to determine the
network boundaries for a SIP DECT System. The Aggregated subnet mask covers
the network segments connected using routers that support IP multicast.
Example: DAPs in three subnets:
• 192.168.1.0/24
• 192.168.4.0/24
• 192.168.5.0/24
For this example, enter the Aggregated Subnet Mask 255.255.248.0.
