1	ATV-25 Pair Identification Optimizing Field Testing and Records Integrity Note: Images take time to load
2	Pair Identification Options The ATV-25 provides features useful in automatic and manual pair identification.
3	ID Tone ID Tone is compatible with standard tone probes in use in the field. Dual frequency capability and multiple modes are provided to meet most applications. The table below shows the frequency and mode options available.
4	Automatic Tone Search Automates the process of tone probing for a pair More accurate than using an inductive probe Searches 25 pair Works with standard tone probes 577 Hz and 1004 Hz tone supported Searches for metallic or simplex tone
5	Automatic Tone Search The Tone Search result screen shows a matrix of the 25 pairs. Pairs with tone that meets the internal threshold have black backgrounds. The display indicates the frequency, mode and the identified pair, 14 in this case.
6	Automatic Pair Identification Matches AC and DC parameters for the pair at the local and remote locations Multiple remote units may be used to increase the capability to 50, 74, or 100 pair Pairs are typically identified within 6 seconds
7	End-toEnd Pair Confirmation Verifies Tip and Ring continuity between the local and remote locations Reports opens and reversals Tests working and vacant pairs Measures Tip-Ring and Tip to ground resistance values on vacant pairs Results are stored electronically for uploading to a PC.
