Operation Manual Chapter 1 Introduction Thus user A can request any user to answer and that user can assert its RTS line and thus connect to user A At any time only one user may transmit toward user A if more than one user transmits only the user closest to location A will actually be received When using the bidirectional broadcast receive mode it is necessary to instruct each main link port how to handle the traffic flow and signaling information This is performed by defining the timeslot type as part of the DEF TS command see Megaplex 2100 2104 Installation and Operation Manual Bidirectional Broadcast Ring Mode Applications The bidirectional broadcast mode used for E1 and T1 ring topologies provides capabilities similar to those described above while taking advantage of the resiliency of the E1 and T1 ring topology see general description of the E1 T1 ring topology in the Megaplex 21004 Installation and Operation Manual In addition this mode improves the response time of the master slave polling Note The bidirectional broadcast mode is not available for the module operating in the Megaplex 4100 chassis Figure 1 6 shows a network topology that uses the bidirectional broadcast ring capability Master BID BRD RING BID BRD RING BID BRD RING BID BRD RING BI DIR Legend P Primary S Secondary Figure 1 6 Typical Bidirectional Broadcast Ring Application In the application shown in Figure 1 6 th
