Using LANs
Using a LAN setup (local area network) with the Aspire system complies with the ethernet standard
(10Base-T/100Base-TX).
To connect a telephone to a LAN connection, the system allows the use of an Aspire digital IP 34-
button keyset (referred to as Aspire IPhone), an Aspire digital keyset with an IP Adapter installed or
an H.323 IP digital telephone. For details on installing the IP Adapter, refer to the Aspire Hardware
Manual (P/N 0893100).
If connecting a LAN to a WAN (wide area network), follow the instructions included with the
ADSL modem or gateway device.
IP Address
Equipment/devices used in the Aspire LAN setup must have an IP address assignment. An IP
address assigns a unique address for each device. There are two types of IP addresses: Private and
Global. A Private IP address is not accessible through the internet - a Global IP address can be
accessed through the internet.
With a Private IP address, with equipment that does not access the internet directly, addresses can
be assigned to the equipment within Class A, B or C by assigning a number within the class’s range
of numbers.
With a Global IP Address, connected equipment can be accessed through the internet, so each
address must be unique. To avoid a conflict, the addresses are controlled by ARIN (American Reg-
istry for Internet Numbers). To obtain a Global IP Address, contact ARIN or apply with your local
ISP (internet service provider).
The first one to three groups of numbers (depending on the subnet mask) identify the network on
which your computer is located. The remaining group(s) of numbers identify your computer on that
network.
