Defining connections to remote systems

You can define and manage different types of connections between CICS® regions or from CICS regions to non-CICS systems.

The types of connection that you can create are as follows:
  • Connections for multiregion operation (MRO)
  • Connections for use by the external CICS interface (EXCI)
  • IPIC connections to remote regions
  • ISC over SNA connections to remote systems, using logical unit type 6.2 (APPC) protocols
  • ISC over SNA connections to remote IMS systems, using logical unit type 6.1 protocols
  • Indirect connections for CICS transaction routing

Connections using the ACF/Communications Server application-to-application facilities are treated exactly as though they are intersystem connections and can be defined as either LUTYPE6.1 or APPC links.
