ship Wangnet in quantity. It's sold as a broadband OR a baseband net, depending on
user requirements (and expense budget). Wang's strong foothold in word processing
thoughout the U.S. will give them an edge in many respects. But it's quite an expenive
procuct, and the broadband technology is not really in place yet. And it's CSMA/CD
based. And it's a closed net.
Planet from R̲a̲c̲a̲l̲ ̲M̲i̲l̲g̲o̲ and certainly PolyNet from L̲o̲g̲i̲c̲a̲ are important contenders,
too. PolyNet, however, is based on Cambridge ing principles, bringing it a bit out
of date, but still it's a 10 Mbps system to customers, and it includes inerfaces
for PDP-11, LSI-11, VAX and Multibus (Intel Corp. trade mark) products.
I̲B̲M̲ have not been mentioned in this brief survey, because
their System Communication Division and Office Products
Division have yet to make a move. IBM does market SNA
protocol baed products today, but lack a real local
area net. They are expected to come out with a token-passing
based ring net this fall in the U.S. -- but it will
of course support IBM equipment only (IBM demonstrated
a prototype LAN at the Intercom exhibiton in Geveva,
fall 1983). But, admittedly, this is sufficient to
millions of dp managers in the world.
Summing the matters up, X-Net's strong points are first
and formost it is a true open net interconnecting a
range of different manufacturers' cmputers and terminals,
it quarantees all terminal users access to the net
at all times and end-to-end data delivery as opposed
to CSMA/CD, the concept is a 100% physical distribution
solution to data processing and communication resources
and we ca maintain it's proven technology.
The X-Net product is briefly characterized in the next
section.

X-Net basically consists of a pair of twisted cables
for shared data traffic full duplex, a controller (XCT)
which provides the transport facilities (flow contol,
bit syncronization, quaranteed access, DBA, quaranteed
data delivery, and central software control/distribution).
Wall outlets (XWO) are placed along the databuses where
various kinds of resources (computers) and terminals
(monitor and printrs) can attach to the network by
means of ports (XTP for minis and XEP for mainframes)
or terminal adapters (XTA). X-Net add-ons are CR16,
CR32 and CR5 plus a range of terminals/PC's from other
verdors.
A range of ports and adapters plus the necesary software
to emulate different protocols are available for multivendor
attachments (see latest pricelist with delivery table)
as well as ports (XCP) for interconnection of local
net-works to a long haul net.
Optionally, a network administrato (XNA) can be delivered,
comprising application software on the net, s.a. diagnostic
tools, statistics, electronic mail and the allowance
of symbolic access to all terminal users.
Two important industry standards are supported, RS
232 C and ANSIIX3.64, so is ISO's OSI model and level
2 on X.25.
X-Net will be sold as a terminal/PC net and both CP/M
and MS-DOS based micros must be supported. Micro implementations
with processor-to-processor dialogues are a must in
today's OA market.
Evenually, X-Net will become a standard product, but
there is still a way to go. Today it's very much a
standard hardware product - on finished prototype stage
- whereas the software must be characterized as standard
project software - on development s
