ABSTRACT:
A method of adjusting the sensitivity of a receiver requires the association of a network address of a remote network device, such as a computer, with a first port of a multiport network device, such as a switch. The reception of the network address of the remote network device at a second port of the multiport network device indicates the possible occurrence of a cross-talk condition between networks coupled to the first and second ports. Accordingly, the sensitivity of a receiver associated with the second port is reduced in an attempt to reduce the sensitivity thereof to a point at which cross-talk signals, generated as a result of the cross-talk condition between networks coupled to the first and second ports, are no longer detected. The sensitivity of the receiver may be reduced by increasing a noise threshold level below which signals are not detected.
