Data can be transferred between UTS Systems (Version 4 or Version 2.1) using multiple channel-to-channel connections.

Open Systems Interconnection (OSI)/LAN. The UTS System Version 4 includes all seven layers of the OSI reference model. Optional application services available from Amdahl include OSI FTAM and the X.400 (1984) Message Handling System, which communicates over OSI LAN transports. OSI, LAN, FTAM, and the X.400 Message Handling System conform to U.S. GOSIP 2.0 and U.K. GOSIP 3.1 standards.

System Network Architecture (SNA). Several SNA capabilities are available as optional features. The UTS System Version 4 communicates over a PU5 channel connection to VM and MVS operating systems and provides LU6.2 Advanced Program-to-
Program Communication (APPC). SNA Parallel Transmission Groups allow multiple channel-to-channel connections between the UTS System Version 4 and the same MVS system. Network Job Entry (NJE) is available as an option across channel-to-channel attachments. Common Programming Interface Communications (CPI-C 1990), an element of X/Open's Common Application Environment, provides an API that enables conforming applications to communicate with other applications via IBM's LU 6.2 communication protocol.

Bisynchronous communications. Support for Remote Job Entry (RJE) allows file transfer between a host running the UTS System Version 4 and an MVS JES2 system.

Open Network Computing (ONC). The UTS System Version 4 supports ONC, including Remote Execution, Lock Manager, Auto-mounter, and the Network Information System.

UTS kernel facilities

The current UTS release provides a full set of features and capabilities to optimize system performance.

Symmetric multiprocessing. Full symmetric multiprocessing support for most STREAMS-based communications protocols and all multiprocessor configurations of System/390 families is provided, up to the largest 12-way models.

Expanded storage. A facility within the UTS System Version 4 enables use of additional accessible processor memory (up to 8 gigabytes on Amdahl 5995M models) as paging devices or temporary file systems.

Process scheduling. This facility supports real-time, time-sharing, and scaled fair-time scheduling.

Modularized kernel architecture. This design is based on the UNIX System V Release 4.1 Enhanced Security operating system.

Expanded Fundamental Types. This feature allows expansion of certain data types that have outgrown their original capacity.

Shared libraries. Support is provided for dynamic shared libraries and for static shared libraries that have been created by the UTS System Version 4.

Driver interfaces. The UTS System Version 4 supports the pre-SVR3 version signal, the SVR3 version sigset, and the SVR4 and POSIX-compliant version sigaction.

Asynchronous input/output. The UTS System Version 4 provides asynchronous disk and tape I/O that can significantly increase application throughput.
