Overview of CSCI

The Client Server Communications Interface (CSCI) is a stand-alone component responsible for the passing of request and response packets between a client system and a server system. CSCI is an optional component that lets MVS or RMLS/CSC clients communicate with ACSLS. If you do not use CSCI, you use CSI by default to communicate with ACSLS.

CSCI Connectivity

CSCI provides IPC and TCP/IP connectivity to link the ACSLS server with MVS clients or RMLS/CSC clients

Architecture and Subsystems

The following figure shows an overall CSCI architecture and subsystems.

The following figure shows how the CSCI system connects with the network interface. On the server-side, the data flows from the network hub through the TCP/IP interface, to the CSCI interface. From here, the data flows through an IPC interface to the ACSLS software in both directions, but in a half duplex mode, for example: one direction at a time.
