Response Time Monitor (Rtm); Terminal Multiplexer Adapter (Tma); Network Asset Management; Serial Original Equipment Manufacture Interface (Soemi) - IBM 3174 Introduction Manual

Response Time Monitor (RTM)
The Response Time Monitor (RTM) provides a way to measure, record, and display
end-user response time. It records the time lapse between the operator's pressing
the Enter key and the host's handling the data and returning it to the display
screen. When this information has been gathered over a period of time, it
produces response time statistics that are useful for network management and
evaluation.
Terminal Multiplexer Adapter (TMA)
The Terminal Multiplexer Adapter (TMA) multiplexes the data streams from eight
3270 devices into a single cable. It is supported on models 1 L, 11 L, 1 R, 11 R, 2R,
12R, 3R, and 13R. Each controller can support up to four TMAs. Each TMA has
eight ports, allowing up to thirty two 3270 terminals to be attached to a controller.
Network Asset Management
Network Asset Management supports host requests for Vital Product Data (VPD)
information from a SNA 3174 controller and attached devices. It runs on an SNA
network and enables the host to dynamically request the collection of product
identification information (such as serial numbers) from supported network
components. The information is available to the host as soon as the request is
made.
Serial Original Equipment Manufacture Interface (SOEMI)
The Serial Original Equipment Manufacture Interface (SOEMI) extends the
attachment capabilities of the 3174 controller to include independently
manufactured devices. Designed to provide for engineering, scientific, and
manufacturing environments, this interface provides the means for communication
between the 3174 controller and OEM devices. The OEM devices appear to the
3174 as being no different from other devices.
Microcode Support
The three types of configuration support offered by IBM provide support for 3174
features and enhancements. Each of the next three sections lists a configuration
type and the features and functions for which that configuration type provides
support.
IBM 3174 Configuration Support-A
Configuration Support-A Release 5 provides microcode support for the following:
• Asynchronous Emulation Adapter (AEA)
• 2.4MB diskette drive
• 20MB Fixed Disk Drive
• Type 3A Dual Speed (16/4Mbps) Communication Adapter
• Type 1 Teleprocessing Communication Adapter
• Type 2 Teleprocessing Communication Adapter
• 4Mbps Type 3 Communication Adapter
• Storage Expansion
