14-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT
The interference margin for the XRT83SL314 will be added when the first revision of silicon arrives. The test
configuration for measuring the interference margin is shown in Figure 12.

The receive path detects EQFLAG, RLOS, AIS, QRPD, NCLD, and FLS. 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 (it
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).
The interrupts are categorized in a hierarchical process block. Figure 13 is a simplified block diagram of the
interrupt generation process.
