The Daughter Card, Single Port, Single Mode Fiber, SMF is a microprocessor-controlled, single-line, synchronous interface that provides local or remote interconnection between Q-bus systems and other computer systems with EIA-RS-232-C/CCITT V.28, Daughter Card, Single Port, Single Mode Fiber, SMF V.35, or EIA RS-423/RS-449 interfaces. It operates at speeds from 2,400 bits per second to 56,000 bits per second (depending on the version selected) in half duplex or full duplex. Actual device speed depends on current Digital operating systems and system configuration. (19,200 bits per second is the maximum speed for RS-232 connection.) Depending on the operating system and layered software, the Daughter Card, Single Port, Single Mode Fiber, SMF can support up to 12 tributaries. In point-to-point configurations, the Daughter Card, Single Port, Single Mode Fiber, SMF can communicate with other DMV11 s, DMC 1 1 s DUPlls , DPV1 1 s, or DMR11s. The DMV11 is compatible with Digital's family of modems and with Bell 200 series modems and their equivalents. EIA RS-232-C/CCITT V.28 or EIA RS-423/RS-449 interface.
