US - Last Revised on April 2, 1987



Brief Description of Announcement, Charges, and Availability

     The IBM PC Network Baseband Adapter (#1221) is a feature card
for connecting the new IBM Personal System/2 (TM) Model 30 and IBM
Personal Computers to the baseband IBM PC Network.  It is compatible
with the form factor and bus design of the original PC, yet it is
designed to take advantage of greater Intel 80286 and 8086 processing
speeds.  The adapter supports the NETBOIS interface and the
802.2/Logical Link Control (LLC) protocols via the IBM Local Area
Network Support Program (83X7873) which was also announced today.
This allows the adapter to provide access to broadband IBM PC Network
and IBM Token-Ring Network applications written to the NETBIOS or
APPC/PC interfaces.
       Purchase Price:  $470
       Planned General Availability: April 1987

HIGHLIGHTS
o   A feature card for IBM Personal System/2 Model 30 and IBM
    Personal Computers
o   Modular baseband transceiver for connection to the baseband IBM
    PC Network
o   Supports 802.2/LLC protocols
o   Supports Remote Initial Program Load (RIPL)
o   Uses IBM 5173 PC Network Baseband Extender for additional
    distance and for connecting greater than eight workstations
DESCRIPTION
       The IBM PC Network Baseband Adapter is designed specifically
for the IBM Personal System/2 Model 30.  The card features a 2
megabit-per-second transmission speed with a CSMA/CD access protocol
and supports 802.2/LLC protocols via IBM Local Area Network Support
Program (83X7873).  The selected protocol and NETBIOS interface
support are loaded into PC RAM to execute on the PC system processor.
       The IBM PC Network Baseband Adapter ROM includes Power On Self
Test (POST) diagnostics, which help the customer to identify adapter
failure without diagnostic diskettes or printed problem determination
procedures.
       The adapter also supports the Remote Initial Program Load
(RIPL) feature.
       The IBM PC Network Baseband Adapter supports daisy chain as
well as star topologies via the IBM 5173 PC Network Baseband Extender
announced today in Product Announcement 187-083. Up to eight
workstations can be linked together in a chain topology with an
overall length of up to 200 feet of 4-wire twisted pair IBM Cabling
System Type 3 specifications telephone wire.  A chain of workstations
linked to the 5173 can have an overall length of up to 400 feet.  Up
to ten daisy chains with eight workstations each can connect to the
Baseband Extender for a maximum of 80 workstations in the baseband
IBM PC Network.  The cable required for the baseband adapter must be
ordered separately.
