Abstract

A transceiver (72) allows a monitoring device (30) to be coupled and decoupled without interrupting communication between a pair of devices, one of which includes the transceiver. The transceiver includes three pairs of ports and two pairs of buffers. The first send and receive ports (40, 42) accommodate coupling to a host device (20) including the transceiver and the second send and receive ports (44, 46) accommodate coupling to a transmission line. The third pair of ports (74, 76) are monitoring ports for coupling to the monitoring device. The first pair of buffers form a bidirectional communication link between the first send and receive ports and the second send and receive ports. The second pair of buffers (82, 88) form a unidirectional communication link transmitting signals to the monitoring device.
