Model RM356 Modem Router Installation Guide

Telephone Line Checklist

The Model RM356 Modem Router connects to the Public Switched Telephone Network (PSTN)
using a standard analog voice line. When ordering telephone service, the following information
should be verified:
Line Quality
Though the modem is capable of 56 Kbps download perform ance, the condition of your
telephone line and your local public telephone infrastructure may limit your actual data rate.
For example:
FCC rules limit the data rate t o 53 Kbps in the Unite d States.
The use of repeaters between your premises and the central office w ill limit your
performance to 33 Kbps.
If your data rate is substantially less than 50 Kbps, you may want to consult your telephone
company regarding the quality of your line.
Calling Line Identification (CLID)
If you require CLID for security, you must order CLID for your line from your local carrier.

ISP Checklist

If you will be contracting with an Inte rnet service provider (ISP) for In ternet access, you must
choose between a single-user account a nd a m ultiuser LAN account. You c an connect a multiuser
network through a single-user account by using the Network Address Translator (NAT) feature of
your router.

Single-User Account

In a single-user account, you are assigned only one registered Internet Protocol (IP) address. This
address may be a permanent fixed address or it may be a different address assigned dynamically
each time you log in to the account. The NAT feature of your router will map the IP addresses of
your network to this address for accessing the Internet. Some applications may be incompatible
with NAT.

LAN Account

In a LAN account, you will be assigned a register ed IP address for your router and one for each
PC or workstation in your local network. A LAN account i s typically more expensive than a
single-user account.

Account Information

Your ISP should give you the following basic information for your account whether it is a single-
user or LAN account:
A local phone number for accessing the ISP
A login name
•A password
IP address(es) unless dynamically assigned
DNS server IP address(es) of the ISP
