Octal T1/E1/J1 Transceiver

Datasheet
The monitored line signal (input or output) goes through channel 0 clock and data recovery. The
signal can be observed digitally at the RCLK/RPOS/RNEG outputs. This feature can also be used
to create timing interfaces derived from a E1 signal. Channel 0 also displays the appropriate LOS
state for the monitored channel, both in transmit and receive directions.
In addition, channel 0 can be configured to a Remote Loopback while in monitoring mode (TCLK0
must be active in order for this operation to take place). This will output the same data as in the
signal being monitored at the channel 0 output (TTIP/TRING). The output signal can then be
connected to a standard test equipment with an E1 electrical interface for monitoring purposes (non
-intrusive monitoring).
2.9
Hitless Protection Switching (HPS)
The LXT384 transceivers include an output driver tristatability feature for T1/E1 redundancy
applications. This feature greatly reduces the cost of implementing redundancy protection by
eliminating external relays. Please refer to Application Note 119 for guidelines for implementing
redundancy systems for both T1 and E1 operation using the LXT380/1/4/6/8.
