1.3

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).
