Project for Development of New Protocol Hardware and Software for LSI-11 to Accommodate AUTODIN II ADCCP-HDLC, and X.25. Appendix A

Abstract

This manual contains information on the application, installation, operations, and maintenance of the XQ/CP. Included is information on physical characteristics, logic operations, programming, and interface specifications. The XQ/CP is a communication processor that can be programmed to deal with telecommunication protocols, the pre- and post-processing of information, and general applications that are suitable for microprocessor execution. The XQ/CP can be operated as a stand-alone unit or an an intelligent peripheral attachment to the DEC LST-11 system. The XQ/CP comprises three circuit boards that are interconnected. When tied into the DEC LSI-11 QBUS, the use of Multichannel Direct Memory Access (MDMA) circuit board is required along with the XQ/CP boards. The I-Board provides the interface between the XQ/CP External Microprocessor Bus and the MDMA Subsystem Interface Bus (SIB). The MDMA is a communications controller that allows multiple attachments to operate in the DMA mode with the LSI-11.
