The following tests can be run:
» Test Menu/Echo Request
Write security: 4, Read security: 5
When activated, the echo request test will begin sending continuous
PPP echo request packets to any open LCP ports. Results are dis-
played on the screen. This is not used in the Frame Relay mode.
» Test Menu/2047 Loopback
Write security: 4, Read security: 5
When activated, a loopback command is sent to the far-end HDSL de-
vice and an internal 2047 pattern is continually transmitted towards
the HDSL circuit. Loopbacked data is checked and an error count is
maintained.
