Prestige 128+ ISDN Router
xxiv Preface
Supplemental Service Activation Keys – Sometimes called ‘buttons,’ most of
the supplemental services supported by the Prestige require that an activation key
be set before a feature can be used.
You have now collected all of the necessary information about your ISDN
telephone line. Make sure that these values are entered into your ‘Setup
Information Worksheet’ before you continue to the next section.
Collecting Ethernet Setup Information
IP Address - An IP Address is required for TCP/IP protocol. The IP Address is
the unique 32-bit number assigned to your Prestige. This address is written in
dotted decimal notation (four 8-bit numbers, between 0 and 255, separated by
periods), e.g., 192.168.1.1.
Record the IP Address into the worksheet as assigned by your network
administrator. Please note that every machine on an internet must have a unique
IP address - do not assign an arbitrary address to any machine. If you are not
sure as to which IP address to assign to the Prestige, contact your LAN
administrator or refer to Chapter 4 of this guide for more details.
IP Subnet Mask - This field is required for TCP/IP protocol. An IP address
consists of two parts, the network ID and the host ID. The IP Subnet Mask is
used to specify the network ID portion of the address, expressed in dotted
decimal notation. The Prestige automatically calculates this mask based on the IP
address that you assign. Unless you have special need for subnetting, use the
default mask as calculated by the Prestige.
The table below lists some examples of IP subnet masks and the number of hosts
that are allowed. Consult your network administrator if you are unsure of this
value.
