Station testing

Station testing helps to determine if a station functions correctly while the

station connects to a loop and a line circuit group. Station testing occurs

under the line maintenance subsystem (LNS) at the MAP terminal or from a

station. The testing occurs from a station in the events of the station ringer

and short circuit tests that you can dial. Stations tests are manual. Results

from station tests must return to the station.

The system does not support the silent switchman test because a subscriber

loop in cutoff interferes with the ringing.
