Table 4-1. Remote Requirements for Cable Tests

Remote Unit

Required. Supported by all remotes.

Required. Supported by all remotes.

Required. Supported by all remotes.

Required. Supported by smart remotes and DSP-100 main units used as remotes. With a standard remote, results can be obtained by switching the positions of the remote and main unit and retesting.

Optional. Supported by all remotes. Without a remote, the limit and pass/fail result are not shown.

Optional. Supported by all remotes.

Required. Supported by all remotes.

Optional. Supported by all remotes. Without a remote, the resistance of cable pairs is reported as “open,” assuming the cable pair is not shorted.

Required. Supported by all remotes.

Required. Supported by DSP-2000 smart remote.

Required. Supported by all remotes. Test available only in Autotest mode.

Required. Supported by smart remotes and DSP-100 main units used as remotes. With a standard remote, results can be obtained by switching the positions of the remote and main unit and retesting. Test is available only in Autotest mode.

Required. Supported by DSP-2000 smart remote. Test is available only in Autotest mode.

Optional. Supported by all remotes. Without a remote, the end of the cable is not identified.

Recommended. Supported by all remotes. Without a remote, results from tests on short cables may be unreliable.

Recommended. Supported by all remotes. Without a remote, test results may not represent the level of noise present on a terminated cable.

Never used.
