Manufacturer’s Description

This network module has four synchronous serial interfaces, and supports a total full-duplex throughput of 8 megabits per second (Mbps), which can be realized over one port (at 8Mb/s) or across all four ports (at 2Mb/s on each port). Each port supports full-duplex and half-duplex operation at T1 and E1 speeds. All ports use identical DB-60 connectors that support five interface types (RS-232, RS-449, RS-530, V.35, X.21) in either DTE or DCE mode.
