DESCRIPTION AND OPERATION
E. Fault Isolation of the SSCVR (Subtask 23-70-44-810-005-A01) (1) General
(a) To fault isolate a SSCVR, perform the test procedure. If the test procedure can be completed from start to finish without failure, the SSCVR can be returned to service.
(b) The SSCVR employs BIT functions using three methods:
• Power on initialization
• Commanded self-test
• Background continuous test.
(c) A history of the BIT status is maintained in crash protected solid state memory for product trend analysis and warranty support. In addition, the SSCVR provides status discrete output, maintenance discrete output, and front panel indicator to indicate BIT failures.
(d) Power on initialization verifies operation of the SSCVR when it is practicable, given the specified 250 millisecond power on to recording delay. Functions tested include the main processor, RAM memory check, program checksum verification, testing of the CSMU, and partial testing of the audio interface. Commanded self-test is invoked through the initiate self-test discrete and is a much more rigorous, complete test. The background continuous monitor test utilizes spare processor time to continuously monitor the integrity of the SSCVR. All BIT failures are recorded in solid-state memory for extraction by Ground Support Equipment.
(e) The SSCVR implements extensive BIT for detection of errors within the unit. The SSCVR has been designed to detect and isolate errors to the SRU level. BIT also detects and reports fault conditions to the component level for depot level repair.
(2) Record Areas (a) General
1 The CPM consists of 27 standard 1 megabyte flash devices (Chips 0 thru 26) and 1 EEPROM located at Chip 28 (flash Chip 27 is not installed and will not be used or included in the design). Each flash device consists of 16 blocks (blocks 0 thru 15).
There are two (30 minute configuration) or three (2 hour configuration) areas where information can be recorded follows:
• NB voice area
• WB area microphone area
• MIX area (for 2 hour configuration only).
(b) NB Area
1 For both configurations, NB area consists of four pointers (NB Start Page, NB Current Page, NB Current Offset, and NB next block to erase pointers) in EEPROM.
a 30 Minute Configuration
(1) Narrow band area consists of 16 standard 1 megabyte flash devices (Chips 0 thru 15). The NB flash area will be written as follows:
• Block 0 of Chip 0, Block 0 of Chip 1. Block 0 of Chip 15
• Block 1 of Chip 0, etc.
(2) Table 1006 and Table 1007 list the cross-reference between chip number and reference designation.
