Fl3. A pass count occurs after all ranges selected for testing are
*completed and a retest requested. The count appears in
decimal, runs from 
“00” to “99”, and repeats beginning at
” 00.”
4. Testing stops on the range for that pass only when a failure
occurs. At the start of each pass, all ranges selected for
testing are retested if the retest option was selected.
5. If a failure occurs on ranges CO and Cl, replace the MPB85
card (FB-17215-A) and cable in the 
OMNI SI Get Started
File and then the Expansion File. Reinstall the original card if
the replacement does not fix the problem.
Channel Memory Test9.9 This test checks the ability of the channel memory to store
information on the Channel Memory 8085 card (FB-17218-A).
None, one, or both channel memories can be tested. In order to
test both channels memories, an Expansion File is needed.

Channel Memory9.9.1 Use the following steps to conduct the Channel Memory
Testing ProceduresTest:
1. Select option 
” 1” from the Menu of Test Options. The system
responds:
CHANNEL MEMORY TEST
ENTER EACH FILE (0 
- GET STARTED / 1 - EXPANSION)
THAT IS TO BE TESTED, THEN A (CR)
8187M-345 
						

							2. Enter a “0” if the Get Started File is tested and/or a “1” if the
Expansion File is tested, followed by a (CR). If both files’
channel memories are tested, type “01”. If all files are
selected, then a (CR) is not needed. The system responds:
FOR RETEST TYPE 0; OTHERWISE TYPE 1
3. Now refer to step five of the System Memory Test procedures
and continue (paragraph 96.1)..: Test Results9.9.2 All of the test results described may not appear since they
depend on how the Channel Memory Test was set up.

LAS each file is finished with a pass, the message “PASS”
along with the pass number is displayed under each file’s
header. The pass number is incremented by one with each
pass. The count is reset to 00 after reaching 99 if multiple
tests are requested.
EXAMPLE:
A successful single test for both files causes the following
message to be displayed:
FILES:GET STARTEDEXPANSION
PASS 00PASS 00
2. An error message giving the file and test which failed, the
locations where the failure was detected, and the data written
versus the data read is displayed on finding a failure. The
error message appears as follows:
GET STARTED FILE
TEST 
#lMEMORY FAILURE LOCATION: 0400
DATA: WRITTEN AA
READ FF
3. The entire range(s) are tested.
Paging Card Test9.10 This test checks the Memory Paging 16 Page card (FB-
17213-BOA) for wrong settings or multiple writes. One
memory location for each range on a page is checked. Memory
addresses are initialized to “FF“ and then the page number of
that particular page is written. The memory is checked for
proper numbering and cross-checked for duplicate writes. All
memory pages are thus checked for no writes or duplicate
writes.
Paging Card8.10.1 The following action begins the Paging Card Test:
Testing ProceduresSelect option “2” from the Menu of Test Options and follow the
procedures.

							TL-130200-1001Test Results9.192 After completion of the Paging Card Test, the system
responds with the following :
1. With successful completion of the test the system responds:
PAGING CARD PASSES TEST
2. Memory read-after-write error on instruction page 0,
memory address 1100. The system responds:
MEMORY WRITE FAILURE ON PAGING TEST
PAGE 00
MEMORY FAILURE LOCATION IS: 1100
3. Paging failure in which page write went to Instruction Page 1
instead of instruction page 0 writing to range 
#l. The system
responds:

Network Test9.11 This test checks the networking capability of the Channel
Memory 8085 card (FB-17218-A). The card test follows:
1. Control memories for a time slot are written to return a PCM
sample.
2. “FF“ is written into channel memory for that time slot. When it
recognizes the “FF”, the card sends the test “10101010” ,or its
inverse to the network and expects the same thing back during
the time slot. The pattern is inverted for the next frame. A
failure latch is set if the test pattern is not returned correctly.
Network Testing9.11.1 Use the following steps to conduct the Network Test:
Procedures
1. Select Option ” 3” from the Menu of Test Options. The system
responds:
NETWORK TEST
2. The system runs the Network Test.
Test Results9.11.2 Depending on the results, the system responds in the
following manner:
1. If the network test was successful, the system responds:
NETWORK PASSES TEST
8/87M-347 
						

							TL-130200-1001
2. If the channel memory was not initialized, the system responds:
NETWORK FAILURE: CAN’T WRITE TO CHANNEL
MEMORY
TESTING STOPPED DUE TO THE ABOVE ERRORS
3. If control memories A or B were not initialized, the system
responds:
NETWORK FAILURE: CAN’T WRITE TO CONTROL TESTING STOPPED DUE TO THE ABOVE ERRORS
4.. If pad memory was not initialized, the system responds:
NETWORK FAILURE: CAN’T WRITE TO PAD MEMORY
TESTING STOPPED DUE TO ABOVE ERRORS
5. If channel, control, or pad memory was not read, testing ends
and the system responds:
READ AFTER WRITE FAILURE
MEMORY FAILURE LOCATION IS: XXXX
6. If network failure occurs three times, the system responds:
NETWORK FAILURE: ADDRESS = XXXX
XXXX is the memory address at which the fault is located.
Use the following table to determine which card caused the
failure:
Memory AddressProblem Area
M-3480200 to 
025F0400 to 
045FExpansion File Channel Memory
Get Started File Channel Memory
I0800 to 
08BF1 Control Memory AI
OAOO to OABFControl Memory B
OCOO to OCBFPad Memory
NOTE: A network failure occurs if there is a problem writing to
channel, control, or pad memory, or if the latch bit returned
during the test indicates failure.
81875210 
						

							TL-130200-1001Fault Correction9.11.3 The following steps correct faults detected by the Network
Test:
1. If the problem was found to be initializing or writing to channel,
control, or pad memory, replace the Channel Memory 8085
card (FB-17218-A). Reinstall the original card if the problem
continues after replacement.
2. Repeat the Network Test.
3. If the failure continues, check all cabinet cables for short
circuits. If an open is found, replace the faulty cable and rerun
the Network Test.
NOTE: Steps 4, 5, and 6 are used if there was no initialization or
write check error.
4. Replace the Expandable Pulse Code Modulation Network card
(FB-17217-A) and repeat the Network Test. Reinstall the
original card if the problem continues after replacement,
5 Replace the Intermediate Network Clock card 
(FB-20771-
1A) or Synchronized Intermediate Network Clock card (FB-20922-A) and repeat the Network Test. Reinstall the original
card(s) if the problem continues after replacement.
6. Perform the System Memory Test.
Disk Device Tests9.12 These tests check the operation of the disk subsystem
including the File Management System Data card 
(FB-17229-BOA), the disk drive, and the Administrative Maintenance
Processor A (FB-17229-A) and B (FB-17230-BOA) cards.
Diagnostic tests of the disk subsystem sends sequences of
command messages to the FMSD card. Status messages and
other outputs returned by the File Management System measure
the successful execution of each command. Because of the
nature of these tests, successful completion means that the
tested devices are fully operational.
Disk Device Testing
9.12.1 Use the following steps to conduct Disk Device Tests :
Procedures
1. Select option 
“4” from the Menu of Test Options. The system
responds:
DISK DEVICE TESTS
2. The system conducts a test of the File Management System
(FMS) to CEC communications link. This enables further
non-destructive testing. The system also conducts a check
of the on-board FMS RAM, and an equipment status check
for site configuration.

Test Device #O9.12.3 Test device #O (option 1) instructs the system to perform
a read/write verification for the FMS and the hard disk 
(10MBYTEFixed Disk). The hard disk must be verified prior to starting the
test. If the test is performed on a drive which is not formatted, the
test will fail.
Testing fixed disk devices begins with a request to the controller
board to execute its on-board diagnostic programs. These
programs test the disk drive controller, its on-board RAM
memory, and the disk drive. Successful completion of these
tests ensures that the controller is communicating with File
Management Systems (FMS) and that the disk is properly
formatted.
Following the successful completion of the controller’s on-board
diagnostic programs, a test file containing up to 2,500 records is
created. Data is written to the disk and then read back to prove
the disk’s rear and write capabilities. After reading all records
from disk, the 
?st file is deleted and the fixed disk test
terminated.

in addition, three diagnostic tests performed by the disk drive
controller are executed before creating the test file. These
diagnostic programs test the disk drive controller, the disk drive
controller buffer RAM, and the disk drive itself. Successful
completion of these tests ensures communication between the
controller and host, verifies that the disk has been formatted, and
guarantees that the first field ID of each track is good. if any
errors are found, ail, except three, will be reported to the user
and will result in termination of the test. if the diagnostics are
successful, a test file will be created and a read/write identical to
that performed for the floppy disk will be executed. Successful
completion of the Fixed Device Test is shown in the prompt
below.
