Receive Sensitivity
To meet short haul requirements, the XRT83SL216 can accept E1 signals that have been attenuated by 11dB
of flat loss in E1 mode. The test configuration for measuring the receive sensitivity is shown in Figure 6.

General Alarm Detection and Interrupt Generation
The receive path detects RLOS and AIS. These alarms can be individually masked to prevent the alarm from
triggering an interrupt. To enable interrupt generation, the Global Interrupt Enable (GIE) bit must be set "High"
in the appropriate global register. Any time a change in status occurs (if the alarms are enabled), the interrupt
pin will pull "Low" to indicate an alarm has occurred. Once the status registers have been read, the INT pin will
return "High". The status registers are Reset Upon Read (RUR).
NOTE: The interrupt pin is an Open-Drain output that requires a 10k
pull-up resistor.
