Item Description
Type of Account Instant Internet can provide access to your entire network
through a single Internet Protocol (IP) address for
unlimited access to the Internet:
• If you want to use public IP addresses, request a
network account.
• If you want to use Network Address Translation (NAT)
or you are using the Instant Internet unit as an
IPX-to-IP gateway, request a single-user account.
Your ISP will provide you with a user name, password,
primary access phone number, optional alternate access
phone number, and name server IP address. Record this
information on
page 33 .
Dial-up Protocols If you are using a dial-up connection in North America,
ensure that your ISP supplies true IP service using PPP
protocols for analog and ISDN connections. ISDN
requires the synchronous PPP protocol with
authentication via Password Authentication Protocol
(PAP) or Challenge Handshake Authentication Protocol
(CHAP).
For a 128K connection, Multilink PPP must be supported.
Some ISPs use their own proprietary protocols or, for
ISDN, V.120 rate adaption. Instant Internet does not
support these proprietary protocols.
ISDN Service When you obtain ISDN service, your telephone company
may assign one or two Service Profile Identifier (SPID)
numbers to your line. Record the SPID number(s) on
page 33 .
Leased-Line
Connection Leased-line (T1, E1, V.35, or X.21) connections require
synchronous PPP or frame relay. The Instant Internet
400-S unit supports one PVC for frame relay.
T1 Connection If you are using a T1 connection, ask your T1 service
provider for the framing format, line encoding, data type,
line build-out, rate multiplier, and line speed. Record this
information on
page 33 .
