Alarm Detection A block alarm will be generated whenever the BLOCK_ERR has an
error bit set. The types of block error for the resource block are defined
above (see Table 5-2).
A write alarm is generated whenever the WRITE_LOCK parameter is
cleared. The priority of the write alarm is set in the following
parameter:
• WRITE_PRI
Alarms are grouped into five levels of priority
:

VCR The number of configurable VCRs is 8. The parameter is not contained
or viewable within the resource block, but it does apply to all blocks.
