    | Diagnostics HAPTER Traceroute RACEROUTE Traceroute discovers the routes that packets take when traveling to a destination. Traceroute works by taking advantage of the error messages generated by routers when a packet exceeds its time-to-live (TTL) value. The traceroute command first sends probe datagrams with the TTL value set at one.

    | Administration Settings HAPTER Password Setup ASSWORD ETUP Management access to the ADSL Router is controlled through different levels of user name and password. To protect access to the management interface, you need to configure a new Administrator’s password as soon as possible. If a new password is not configured, then anyone having access to the ADSL Router may be able to compromise the unit's security by entering the default values.

    ABLES AND INOUTS WISTED ABLE SSIGNMENTS For 10/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. For 1000BASE-T connections the twisted-pair cable must have four pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes.
