Setup and Preparation

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 performance, 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 to 53 Kbps in the United States.

–The use of repeaters between your premises and the central ofﬁce will 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 Internet service provider (ISP) for Internet access, you must choose between a single-user account and a multiuser LAN account. You can 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 registered IP address for your router and one for each PC or workstation in your local network. A LAN account is 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
