Chapter 3 Basic Router Configuration

Configuring Command-Line Access

If you plan to connect over an ADSL or G.SHDSL line:

Order the appropriate line from your public telephone service provider.

For ADSL lines—Ensure that the ADSL signaling type is DMT (also known as ANSI T1.413) or DMT Issue 2.

For G.SHDSL lines—Verify that the G.SHDSL line conforms to the ITU G.991.2 standard and supports Annex A (North America) or Annex B (Europe).

After you have collected the appropriate information, you can perform a full configuration on your router, beginning with the tasks in the “Configuring Command-Line Access” section on page 3-5.
