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
