The PGM5537-MP is a Multi-Protocol (MP) MUX that is used to connect terminal equipment to Token Ring networks. The PGM5537-MP enables a single computer to be used to support multiple network protocol standards, such as Ethernet, FDDI, Token Ring, and SDLC. This allows the computer to communicate with multiple networks simultaneously. The PGM5537-MP is a half-duplex, four port, high performance, and cost-effective multiplexer. It has integrated intelligence to support four different network protocol standards simultaneously. The PGM5537-MP also supports point-to-point and multi-drop Token Ring configurations, which allows the multiplexer to act as an intermediate device for connecting different types of networks. Additionally, the PGM5537-MP’s Network Synchronization capability provides accurate, managed synchronization between various Token Ring networks. Its flexible data rate switching, along with its smart interface feature, enables easy configuration with minimal interruption to the network. This makes it a reliable and versatile solution for connecting terminal equipment to Token Ring networks.
