摘要
The disclosure relates to an arrangement in a marker pathfinding scheme for providing immediate ringing of the called subscriber terminal. The terminating junctors available to a called terminal are divided into groups with each group receiving the ringing current in a different time period. Each ringing period is preceded by an enabling pulse such that the marker in its pathfinding operation tests first those terminating junctors corresponding to the then occurring enabling pulse.
