is to protect the traffic of a failed T1/E1 transmission line in a ring network. If a T1/E1 line
fails then PARS will provide protection to rerouting the traffic on that line. This means that all
24 time slots (totaling to the DS1 rate) or 30 time slots (totaling to the E1 rate) will be
completely protected.
