Method of Automatically Identifying Cables

      A method to identify different types of Wide Area Network (WAN)
cables is disclosed.  Each attached cable of a machine can identify
itself, through a one-wire communication device, to the main system
when inquired.

      A machine which supports multiple WAN physical connections via
an universal connector needs different type of cables to connect to a
specific network.  For example, a machine supports RS232, V.36,
RS449, and X.21 through a single connector.  Only one of those WAN
cables can be connected and supported at one time.  This disclosure
specifies a one-wire protocal device to be assembled in the cable to
show its identification.  Each device is programmed to its unique
cable ID and installed inside the cable connector.  The ID
information is transferred to the main system when the cable is
connected to the machine.

      An example to accomplish this is by using DALLAS
Semiconductor's DS2401.  This device is small enough to be installed
inside a miniture D-shell connector.  DS2401 is programmed to a code
pattern to represent a specific cable type.
