The Dual LANStreamer MC 32 Adapter offers two independent RJ-45
token-ring ports for either UTP (without external filters) or STP
wiring at either 16Mbps or 4Mbps.
The capability of two independent RJ-45 token-ring ports on one adapter provides cost and slot savings to customers requiring multiple LANs attached to their servers.
The automatic media-detect capability of this adapter automatically determines if an STP or UTP cable is attached to each of the RJ-45 connectors and sets the adapter accordingly, without manual configuration by the user. This capability allows easy connection to either telephone twisted-pair media or the IBM Cabling System media.
The enhanced usability offerings of the new adapter make it easy to
install. Ring Speed Listen determines the speed of the ring (either
16Mbps or 4Mbps) and automatically switches the adapter to the
correct speed without any manual intervention.
The enhanced token-ring technology incorporated in the Dual
LANStreamer MC 32 Adapter provides significant performance
capabilities that include frame processing capacity of over 30,000
frames per second and very low latency (under 50 microseconds). The
Dual LANStreamer MC 32 Adapter provides data and addressing support
for 32 bits of information to be passed across the Micro Channel.
This support provides greater throughput as well as addressing
capabilities for growing environments that require addressing above
the 16MB range. Greater throughput and 40MB/sec streaming data
capability makes the Dual LANStreamer MC 32 Adapter ideal for
high-end servers in today's environments.
The high throughput provided by the Dual LANStreamer MC 32 Adapter protects current hardware investments by extending the time before additional hardware is required due to LAN activity increases.
LANStreamer technology provides a platform that allows growth to meet new, higher-demand networks. The multiple receive and priority transmit channels included with this technology also allow use of this adapter in multimedia applications.
Another benefit is the hardware capability to support full-duplex token-ring communication. Software support is planned to be available later, but it is not expected that purchasers of this adapter will need to change hardware.
In addition, the Dual LANStreamer MC 32 Adapter is compatible with
other IBM token-ring adapters operating at the same speed (16Mbps or
4Mbps). The protocols conform to IEEE 802.5 and ECMA 89 standards
and have been enhanced to include new proposals for media attachment
in the IEEE 802.5 standards. These proposals make the token ring
even more reliable.
Device Drivers Provided with Adapter
The device drivers included with the Dual LANStreamer MC 32 Adapter
provide easy access to OS/2, DOS, and NetWare 3.1x and 4.x. This
reduces the amount of time needed to install the new adapters and
increases user productivity. The drivers provided are for servers
With the Dual LANStreamer MC 32 Adapter's high throughput capacity, more clients can be supported using a single adapter without degrading customer response time. The adapter's faster file transfer performance can also reduce the time it takes to download files from servers in a NetWare 3.11 environment by 20% to 30%. Similar improvements can be expected in a LAN server environment.
The device drivers included with the Dual LANStreamer MC 32 Adapter
provide easy access to OS/2, DOS, and NetWare 3.1 and 4.0 for
Enhanced Adapter Technology
Compared to existing products, the architecture of the Dual LANStreamer MC 32 Adapter integrates many functions into the hardware that greatly improve frame processing and overall performance of the new LAN adapter. To provide an easy migration to multimedia applications without adding new hardware, priority transmit and receive channels are included in the technology.
In addition to the priority channel, the hardware is enabled to
support a full-duplex token ring. Software is planned to be
available later in the year; however, the upgrade is not expected to
require any hardware modifications. The enhanced technology allows
customers to take advantage of the higher speed capabilities
necessary to support growing traffic demands.
The high throughput of the Dual LANStreamer MC 32 Adapter provides
the potential to run additional applications on PS/2(R) or other MC
Many customers require the capability to monitor down to the ring
level of their networks. The Dual LANStreamer MC 32 Adapter
continues to support the same level of network management as the
existing IBM 16/4 Token-Ring Adapter. Functions include reporting of
ring utilization, critical resource monitoring, and many other key
network management functions.
Conformance to the IEEE 802.5 standard allows the Dual LANStreamer MC
32 Adapter to be monitored and managed by the same tools in use
today. The on-card self test verifies the adapter before its
insertion into the ring. Error counters are passed to existing
applications to provide a view of the ring's condition if problems
When utilized with the PS/2 model 95 with data streaming, the Dual LANStreamer MC 32 Adapter leads the industry in two-port adapter performance and should be considered in environments where increased server performance and a two-port adapter are desired. The MC 32 Adapter supports unshielded twisted pair and the IBM Cabling System.
The existing IBM Auto LANStreamer MC 32 Adapter is a single-port, high-performance workstation/server adapter and should be considered for single-port server or high-performance workstation requirements. Other options for MC workstations include the IBM LANStreamer MC 16 Adapter and IBM 16/4 Token-Ring Network Adapter/A. Evaluate individual software and hardware configurations for use of a LANStreamer adapter in a client environment. A factor to consider is the memory available for drivers. The IBM LANStreamer MC 16 Adapter drivers use Network Driver Interface Specifications (NDIS) and have logical link control (LLC) in PC memory.
The current Token-Ring 16/4 Adapter/A should be used:

Cable Orders: The Dual LANStreamer MC 32 Adapter utilizes a single media connector (one for each port) for both UTP and STP. Two IBM RJ45 STP/D-shell Conversion Cables (#3436, 60G1066) are supplied with each adapter to enable existing STP adapter cables (6339098) to be connected to the Dual LANStreamer MC 32 Adapter. A new STP adapter cable for direct connection to the adapter's RJ-45 ports is also available: IBM Token-Ring RJ45 STP Adapter Cable (#1063, 60G1063).
Customers who want unshielded twisted pair wiring can use standard UTP cabling for attachment to the token-ring network. The UTP cable must have an RJ-45 connector on the adapter end of the cable and the appropriate connector for attachment to the wall outlet on the other end.
