Abstract

A method was needed to increase the flexibility in the types of connection that could be made to a particular communications product. Described is a customer-installable attachment module that satisfies this need. Different modules can then be developed for each of a number of communications types leaving the base unit connection and processor the same.

Customer-Installable Attachment Module

       A method was needed to increase the flexibility in the
types of connection that could be made to a particular communications
product.  Described is a customer-installable attachment module that
satisfies this need.  Different modules can then be developed for
each of a number of communications types leaving the base unit
connection and processor the same.

      The module consists of the required connection hardware
(connector, analog circuitry, connection processor, etc.) along with
the support microcode for that attachment type. Also on the module is
a set of switches for basic configuration.  These are used to set the
basic attachment protocol-dependent parameters.

      The module is enclosed to protect it from handling and give it
substance as a separate entity.  The enclosure labeling provides
module identification using language-insensitive symbols allowing for
world- wide shipment as a single part number.

      This module plugs into the unit as shown in the figure. It is
guided on a carrier mounted on the base and connects with the main
logic board.  The carrier in this case, due to
mechanical/manufacturing constraints, was screwed onto the product
base, but, by altering the design, could have been darted onto the
base.

      The base unit (in this case the base communications connection
was IBM Token-Ring) remains the same and by the customer ordering
different modules, different connectio...
