Serial Device Controller
Testing Procedures9.13.1 Use the following steps to conduct the Serial Device
Controller Test:
1. Select Option “5” from the Menu of Test Options. The system
responds:
TYPE THE SDC PORT 
# YOU WISH TO TEST (0 OR 1) > >
_.2. If Off-Line Diagnostics is not running on this port go to step 4.
Otherwise, the system responds:
TYPE ANY CHARACTER AND IT WILL BE ECHOED ON
THE TERMINAL.
TYPE CONTROL-K TO EXIT FROM THIS TEST
3. Any character key typed on the terminal keyboard will be
echoed at the terminal.
4. If the user selects “O“, the system responds:
THE BAUD RATE IS REQUIRED FOR PORT 1
TYPE THE LETTER OF THE APPROPRIATE BAUD RATE:
A. 110 BAUD
B. 150 BAUD
C. 300 BAUD
D. 600 BAUD
E. 1200 BAUD
F. 2400 BAUD
G. 4800 BAUD
H. 9600 BAUD
5. Enter the correct letter and the system responds:
ATTENTION SHOULD NOW BE DIRECTED TO THE PORT
1 DEVICE
6. To end the test, type CONTROL-K on the tested terminal. The
system responds:
SERIAL DEVICE CONTROLLER TEST OVER
Fault Correction9.13.2 Replace the NSDC card (FB-20992-A). If the wrong
character echoes on the terminal, reload the system and repeat
the test.
Tone Test9.14 This test checks the tone output of the System Pulse Code
Modulation card (FB-20974-A). The test begins with a tone
time slot number written into the control memory of the network.
The user audibly and visually verifies each tone by listening and
following the terminal display.

> 7) > > . .
4. Type the correct circuit number.
Test Results9.14.2 The following Tone Test results may appear:
1. When the Tone Test is successfully completed, the system
immediately connects the phone to the first system tone and
prints the tone description.Tone Test outputs appear in Table
9.4.Type “G” to listen to the next tone.
With the connection of the last tone, the system responds:
END OF TONE TEST
2. If channel memory does not initialize, the system responds:
NETWORK FAILURE: CAN’T WRITE TO CHANNEL
MEMORY
TESTING ENDED DUE TO ABOVE ERRORS
3. If control memory A or B is not initialized, the system responds:
NETWORK FAILURE: CAN’T WRITE TO CONTROL
MEMORY 
< A OR B >TESTING ENDED DUE TO ABOVE ERRORS

4. If Pad memory not initialized, the system responds:
NETWORK FAILURE: CAN’T WRITE TO PAD MEMORY
TESTING ENDED DUE TO ABOVE ERRORS
5. If, during test, channel, control, or pad memory cannot be
read, the system responds:
READ AFTER WRITE FAILURE
MEMORY FAILURE LOCATION IS: XXXX
TESTING ENDED DUE TO ABOVE ERRORS
NOTE: See Network Test Results (Paragraph 8.11) to
memory address of the card causing the problem.
6. The system will continue sending the same tone if a “G” is not
entered to send the next tone.
7. If the phone tested in steps 1 through 4 does not actually exist,
the system responds:
PHONE HARDWARE NOT AVAILABLEFault Correction9.14.3 The following steps correct faults detected by the Tone
Test:
1. If the problem is 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. Replace the System Pulse Code Modulation card 
(FB-
20974-BOA) if tones do not work. Initialize the new card by
writing “FF” into address 
08FF on memory page DO.
3. Repeat the Tone Test.
4. Reinstall and initiate the original card. Conduct the Network
Test and/or the Line/Trunk Test on the circuit if the tones still
do not work.
5. Check the data base for a different phone and repeat the Tone
Test, if the original phone hardware was not available.
Attendant Interface Card9.15 This test checks for transmission errors on the Attendant
Interface Number 2 (ATT12) card (FB-17208-A). The test
consists of sending a data pattern out of the card and looping it
back to the input. The two data patterns are compared to see if
the data pattern received is exactly the same as the data pattern
sent. The test flags an error if the two data patterns somehow
are different.
Temporary wiring changes are required to conduct this test.
Exercise extreme care when making these wiring changes.

							TL-130200-1001Attendant Interface9.15.1Use the following steps to conduct the Attendant Interface
Card TestCard test:
Testing Procedures1. Remove the Attendant Interface card (FB-17208-A) from the
cabinet. Make sure that all four dip-toggle switches are in the
off position. Reinstall the card into the cabinet.
2. Disconnect the cable for the 
Attendant/BLDU interface on the
Attendant Interface card.
3. Strap together the transmit (TRAN) and receive (REC) leads on
the Attendant Interface card (FB-17208-A). Pin 93 is
strapped to pin 95 for Port 0 while pin 56 is strapped to pin 58
- for Port 1.
4. Select Option “7” from the Menu of Test Options. The system
responds:
ATT12 CARD TEST
ENTER THE LOCATION OF THE 
ATT12 CARD
FILE NUMBER (A -- 
>) > >..5. Type the correct file letter. The system responds:
SLOT NUMBER (0 -- 
> 11) > >6. Type the correct universal card slot number. The system
responds:
CIRCUIT NUMBER (0 OR 1) 
> >7. Type the correct circuit number (port) to test.
Test Results9.15.2 The following Attendant Interface Card Test results may
appear:
1. If the 
ATT12 card passes the test, the system responds:
ATT12 CARD PASSES TEST
2. If the 
ATT12 card fails the test, the system responds:
ATT12 CARD FAILURE, DATA = XX
(XX = data pattern which caused failure)
3. If test could not start due to the lack of a steady signal, the
system responds:
NO READY SIGNAL FROM 
ATT12 CARD
4. If no phone hardware exists, the system responds:
M-360
8187PHONE HARDWARE NOT AVAILABLE

							TL-130200-1001Fault Correction9.15.3 The following steps correct faults detected by the
Attendant Interface Card Test:
1. Check the transmit and receive strapping if a “NO READY 
“signal error occurs. Also, remove the AMP connector from the
ATT12 card slot and repeat the test. Replace the ATT12 card ifthe “NO READY“ signal error appears again and repeat the
test.
2. If the ATT12 card itself failed the test, replace the card, and
repeat the test.3. If the actual phone hardware was not available, check for a
different instrument, and repeat the test.
Line/Trunk Test9.16 This test checks the two-way connection between a
specified phone and a test phone. Due to the lack of a central
office response, only those trunk circuits found on the 
Direct-
Inward-Dialing (DID) Trunk card (PILT, FB-51280-A) are
tested. Line circuits found on PCM Off-Premises Station Line
cards (POPS, FB-17250-A) and PCM Line Circuit cards(PLCC, 
FB-17254-1A) are also tested. Attach phones to the
circuits at the CDF by referring to Table 
9.5.an 9.6.

							To end the test and break the transmission path, type any
character.
2. If channel memory does not initialize, the system responds:
NETWORK FAILURE: CAN’T WRITE TO CHANNEL MEMORY
TESTING ENDED DUE TO ABOVE ERRORS
3. If control memory A or B is not initialized, the system responds:
NETWORK FAILURE: CAN’T WRITE TO CONTROL MEMORYTESTING ENDED DUE TO ABOVE ERRORS
4. If pad memory is not initialized, the system responds:
NETWORK FAILURE: CAN’T WRITE TO PAD MEMORY
TESTING ENDED DUE TO ABOVE ERRORS
5. During test if it cannot read channel, control, or pad memory,
the system responds:
READ AFTER WRITE FAILURE
MEMORY LOCATION IS: XXXX
TESTING ENDED DUE TO ABOVE ERRORS
NOTE: See Network Test Results (Paragraph 9.11) to find
memory address of the card causing the problem.
6. If the phones tested in steps one through five do not actually
exist, the system responds:
PHONE HARDWARE NOT AVAILABLE
Fault Correction9.16.3 The following steps correct faults detected by the Line/
Trunk Test:
1. If the transmission path is distorted, replace the tested 
PILTcard, POPS card, or PLCC card, and repeat the test.
2. If no transmission path was established, replace the tested
PILT card, POPS card, or PLCC card, and repeat the test.
3. If replacement of the PILT, POPS, or PLCC card does not
solve the problem, perform the Network Test (see paragraph
8.11).4. If the Network Test passes, reinstall the original card and
repeat the Network Test.
