E-DIG-BD (Multi Application
Platform Board)
The maintenance strategy for E-DIG-BD is the same as the one described for
XXX-BD. Maintenance testing of the common circuit pack is handled by on-board
firmware and SPE controlled tests. Maintenance software queries the firmware for
error and alarm information, status, and test results. The firmware automatically
reports error conditions that will result in SPE-controlled testing.
Board Insertion
The switch makes an additional board query if any of the following circuit packs
are inserted:
For any of the above initial board up-links, the switch sends queries requesting
additional data from the board for administration purposes, while also telling the
board the switch software release and the system type.
For the native mode, the response to the board query downlink messages
consists of several CCMS uplink messages that identify the true board code,
vintage, suffix, emulation type, and the number of reserved slots it needs.
Hyperactivity
The common circuit pack is considered “hyperactive” if the service dispatcher
receives 200 up-link messages from the circuit pack in a 10-second period. Since
MAPD has 32 ports, the hyperactivity limit is increased to 500 up-link messages
per 10seconds. An alarm is issued and the board taken out of service when the
limit reaches 400 or when it hits 500 up-link messages in 10 seconds.
