Time to Live (TTL) value—The Time to Live value is used for the
multicast traffic. If the Time to Live for the multicast is set to 1,
multicast traffic is not forwarded by a Router. If the Time to Live is
higher than 1, multicast packages can be forwarded by the Router,
depending on settings in the Router. If the TTL (for the multicast
packages) is set to 1, leave this aggregated subnet mask empty. If
the TTL (for the multicast packages) is set to a value higher than
1, fill in this aggregated subnet mask to signal to the system which
smaller subnets are connected together as one subnet using a router
supporting IP multicast.
Aggregated Subnet mask—The aggregated subnet mask is the
subnet mask for the DAPs to determine the network boundaries for
an IP DECT Network in which seamless hand over is possible. Use
G.711, which covers the network segments connected together using
routers that support IP multicast.
If there are DAPs outside this aggregated subnet mask, regard the
DAP or DAPs as in a branch office. Note that the IP address of the
PBX is compared with the IP address or addresses of the DAP or
DAPs using this subnet mask. If the IP addresses are in different
