95 / 275 page  MT9072 Data Sheet 95 Zarlink Semiconductor Inc. 14.2.6 E1 Alarms The alarms shown in Table 49 are detected by the receiver. The status register bits provide real time status of the alarm, while the latched status registers provide a latched status indication, and the interrupt status registers provide a latched status indication (if unmasked) which generate a maskable interrupt and which are cleared when read. The persistent status registers provide latched status indication which is only cleared when read while the real time status bit is not set. See the register bit descriptions for additional details. 14.2.7 E1 Automatic Alarms The transmission of RAI and signaling multiframe alarms can be made to function automatically from control bits ARAI and AUTY (register address Y00). When ARAI = 0 and basic frame synchronization is lost (BSYNC = 1 address Y10), the MT9072 will automatically transmit the RAI alarm signal to the far end of the link. The transmission of this alarm signal will cease when basic frame alignment is acquired. When AUTY = 0 and signaling multiframe alignment is not acquired (MSYNC = 1 address Y10), the MT9072 will automatically transmit the multiframe alarm (Y-bit) signal to the far end of the link. This transmission will cease when signaling multiframe alignment is acquired. Description Status Register Latched Status Register Interrupt Status Register Persistent Status Register Bit Add.
