The ATV-25 and ATV R/T enable the user to automatically tag (identify) up to 100 cable pairs at a time.
The ATV-25 is the field unit and controlls all the features of the ATV R/T. The ATV R/T allows testing of any or all of the four 25 pair modules saving test time by targeting specific pairs.
Tagging includes measurement of AC and DC potentials at the near and far ends of the pair under test and matching values. This helps reduce false positives due to tone coupling.
The ATV R/T can be placed in the central office or in the field as needed. A DC power pack is available for use when AC power is not available.
Automatic Pair Identification/Tagging
The ATV-25
also provides pair
tagging capabilities
either in
end-to-end
or half-tap
cable configurations.
Pair tagging
is used to
identify cable
pairs by comparing
electrical
measurements
and a identification
tone for one of up to 100 cable pairs.
This feature
is faster
and more accurate
than manual
tone probe
procedures. Click here to view a presentation on Pair
Identification/Tagging.
The diagram below shows a typical 100 pair tagging connection using and ATV-25 and ATV R/T . One to four tap shoes are used to connect the ATV R/T to a crossconnect, central office frame, or modudlar splices. The tap shoes are moved to the next 100 pair group after tagging is completed for the first group.
