# Signaling modules and logical timeslots

On AG 2000 boards, each signaling module is hardwired to a specific logical timeslot on the local bus. Each signaling module supports four ports of telephone network connectivity and is permanently connected to two RJ-14 connectors (also called a jack). Each jack is therefore bound to the two corresponding timeslots on the local bus. The following illustration shows the relationship between signaling modules, timeslots, and jacks for AG 2000 boards:
