IBM RS/6000 - Manual (Page 51)

Auto LANstreamer Token-Ring PCI Adapter (feature #2979)
It is designed to allow a PCI-based RS/6000 server to attach to 4 Mbps or 16 Mbp
s token-ring local area networks. The adapter automatically selects the correct
token-ring speed (4-16 Mbps). It is compatible with all IBM PS/2 Token-Ring
adapters; no new cables or network components are required.
The adapter has one connector, RJ-45. The RJ-45 connector is used to attach to
Unshielded Twisted Pair (UTP) cabling. A 10-inch conversion cable is included
with the adapter to attach to Shielded Twisted Pair (STP) cabling.
The following are the main characteristics of this adapter:
4 Mbps or 16 Mbps speed (automatically set)
Compatible with IEEE 802.5 specifications
Full Duplex enabled
Occupies one PCI slot
Maximum number of adapters: 6
PCI Ethernet Adapters
Two types of PCI Ethernet adapters are supported depending on the different kind
of connections you need for your Local Area Network.
PCI ETHERNET BNC/RJ-45 ADAPTER (FEATURE #2985)
It supports connections to 10Base2 networks via BNC connectors and to
10BaseT networks via RJ-45 connectors.
PCI ETHERNET AUI/RJ-45 ADAPTER (FEATURE #2987)
It contains a 15-pin DIX Ethernet connector, and it supports 10BaseT networks
via RJ-45 connectors.
Both adapters provide 10 Mbps Ethernet connectivity. They adhere to the PCI
Revision 2.0 and IEEE 802.3 standards. They feature low-cost, high performance
32-bit cards. Each adapter includes three LEDs to provide status to the card's
operation and each includes auto-sense of the media connection. The controller
chip on the card contains integrated DMA buffer management for CPU and bus
utilization and look-ahead packet processing which allows protocol analysis to begin
before the end of the frame is received. It requires one PCI slot, and a maximum
of six adapters can be installed on the Model E20.
ISA X.25 Adapter (feature #2961)
The X.25 Interface Co-Processor Adapter ISA bus provides for the attachment to
synchronous data networks at speeds up to 64 Kbps.
It is important to remember that the IBM AIXLINK/X.25 LPP for AIX is a software
requirement to provide connection to X.25 packet-switched networks. This adapter
provides a single port connection to X.25 networks that will accommodate one of
the three selectable features:
EIA-232D/V.24 interface up to 19.2 Kbps
V.35 interface up to 56/64 Kbps
