If your service provider uses Centrex lines, you must use the WebUI to enter a
line access code to allow calibration to take place. Before connecting the PSTN
lines, see “Line Configuration” on page 89.
If you subscribe to Digital Subscriber Line (DSL) high-speed Internet service
through your telephone line, you must plug each telephone line with DSL
service into a DSL filter. Then plug the DSL filter into the telephone wall jack,
as identified in Figure 17.
