CXDPVB0

DPV is an IOMOD that exercises up to six consecutively addressed synchronous line interfaces (DPV11) by transmitting a standard binary count pattern in either internal or external loopback. The user may also select either bit oriented protocol (BOP) or byte oriented protocol (BCP). The received data is compared with the transmitted data and any errors are reported via the console TTY. All available interfaces (up to 6) are activated and running simultaneously.
