Abstract

Previous cabling to connect mainframe computers and associated devices involved the construction of a cabling closet on site. The closet was fixed in place and generally not amenable to alteration or relocation. The fabrication of the closet required a skilled technician who made each of the connections by hand which typically required several days to complete the job. Despite the relative skill level of the technician who typically performed the installation, these connections were less reliable than might be expected from a factory-built connector. However, due to the complexity of the installation and the fact that each installation was to some degree unique, it was always assumed that the cabling closet must be fabricated on site.

Portable Cabling Closet

       Previous cabling to connect mainframe computers and
associated devices involved the construction of a cabling closet on
site.  The closet was fixed in place and generally not amenable to
alteration or relocation.  The fabrication of the closet required a
skilled technician who made each of the connections by hand which
typically required several days to complete the job.  Despite the
relative skill level of the technician who typically performed the
installation, these connections were less reliable than might be
expected from a factory-built connector. However, due to the
complexity of the installation and the fact that each installation
was to some degree unique, it was always assumed that the cabling
closet must be fabricated on site.

      Other disadvantages associated with the prior art included the
fact that even simple modifications of the installed computer system
were not easily accomplished.  A skilled technician would be required
to revise the connections of the cabling closet.  Further, as the
closet was generally built into the customer's building, any major
relocation of the computer system would require the fabrication of a
new cabling closet.

      The availability of fiber-optic cables also provided an impetus
for the invention.  While the fiber optics created much more
flexibility in locating the component of the computer system at a
distance from the CPU (3 Km as opposed to 400 feet for copper
cabling), fiber-optic connections are even more difficult to
fabricate than t...
