Purpose This task changes the amount of time a path selector switch is delayed for
circuits routed on an SNCP dual-ring interconnect (DRI) topology. In
DRIs, switching contention might occur depending upon the relative
switching speed of the path selector and the transmission delay on the
alternative routes. The hold-off time (HOT) allows you to change switch
times to prevent the switching contention.
