The Multi-port Fast Ethernet f. Alpha, FE-14462-01 is a high-performance, microprocessor-controlled, single-line, synchronous interface that provides local or remote interconnection between UNIBUS PDP 11 and VAX systems and other computer systems with EIA RS- - 232 C/Multi-port Fast Ethernet f. Alpha, FE-14462-01 V.28, Multi-port Fast Ethernet f. Alpha, FE-14462-01 V.35, EIA RS 423/RS 449, or EIA RS 422/RS 449 - - - - - interfaces. The DMR11 implements Multi-port Fast Ethernet f. Alpha, FE-14462-01 in hardware and supports direct memory access data transfers, Multi-port Fast Ethernet f. Alpha, FE-14462-01 point-to-point configurations, and full modern control. It operates at speeds of up to 1 Mbyte per second in half- or full-duplex. Actual device speed depends on current Digital operating systems and system configuration. The DMR11 can communicate with another Multi-port Fast Ethernet f. Alpha, FE-14462-01, a Multi-port Fast Ethernet f. Alpha, FE-14462-01, or any other synchronous interface that implements Multi-port Fast Ethernet f. Alpha, FE-14462-01 Version 3.1 or 4.0. Depending on the version selected, the DMR11 is compatible with Digital's family of modems and with Bell 200 series and Bell 500a 11/5 modems and their equivalents. DMR11-M Includes base module only.
