NetView and VTAM run under the following operating systems:
• Multiple Virtual Storage (MVS)
• Virtual Machine (VM)
• Vi rtual Storage Extended (VSE).
Problem Determination
The gateway feature provides ring-related error processing for the Token-Ring
Network, as well as extensions of the following 3174 problem determination
functions:
• Alerts
• Online tests
• Offline tests
• Error logging
• Trace.
In addition, host notification is provided for Token-Ring error-threshold conditions.
Type 1 Teleprocessing Communication Adapter
The Type 1 Teleprocessing Communication Adapter provides EIA 232D/CCITT V.24
and CCITT V.35 interfaces for SNA/SDLC, SSC, or X.25 remote link attachment to
the host. The adapter is optional on models 1 L, 11 L, 3R, and 13R. It is a base
feature on these models: 1 R, 11 R, 51 R, 61 R, 81 R, and 91 R. With the adapter
installed and with appropriately configured microcode loaded, the 1 L, 11 L, 3R, and
13R can operate on teleprocessing facilities as either model 1 R or 11 R.
Type 2 Teleprocessing Communication Adapter
The Type 2 Teleprocessing Communication Adapter provides
X.21 interface (CCITT V.11) for SNA/SDLC or X.25 remote link attachment to the
host. The adapter is optional on models 1 L, 11 L, 3R, and 13R. It is a base feature
on these models: 2R, 12R, 52R, 62R, 82R, and 92R. With the adapter installed and
with appropriately configured microcode loaded, the 1 L, 11 L, 3R, and 13R can
operate on teleprocessing facilities as either model 2R or 12R.
4Mbps Type 3 Communication Adapter
This adapter provides the ability to operate on an ISM Token-Ring at 4Mbps. It is a
base feature on models 3R and 53R. It is an optional feature on models 1 L, 1 R, 2R,
51 R, and 52R. This adapter enables these controllers to act as models 3R or 53R
for Token-Ring Network communication. (See "Table of Alternate Controller
Configurations" on page A-8 for a table showing which models convert to which
models.) If the Token-Ring Gateway feature is ordered, this adapter comes with
the feature. It can also be ordered separately.
