Page 11: What Precautionary Messages Mean
Translations Guide will be mapped to the Customer Data Schema Reference Manual. What precautionary messages mean The types of precautionary messages used in Nortel Networks documents include attention boxes and danger, warning, and caution messages. An attention box identiﬁes information that is necessary for the proper performance of a procedure or task or the correct interpretation of information or data.

Page 21 1-8 System recovery controller After the SRC receives a request to load a static group member, the SRC builds a dynamic group. The SRC uses the combination of the following two methods to form the group: • The SRC queries the group members for loss of load with the ROM/RAM query message.
Page 22: Limit Of Concurrent Load Activities
• When the SRC begins PM recovery, the SRC notes the absence of a software load in the PM. • The SRC adds the PM to a group for broadcast loading. DMS-100 Family NA100 Recovery Procedures LET0015 and up...
Page 23: Automatic Single Loading
1-10 System recovery controller • When all PMs that need loading are in the group, or 6 min after the ﬁrst PM joined the group, the SRC begins the broadcast-load. Note: If the system requires more than eight automatic broadcast loading requests at the same time, the concurrent activity manager queues the excess.
