X652 XXXX Wrap data test SIS line sets with LCDs of 0,2,4,5, and 6. All installed SIS line adr, except telegraph, are wrapped two at a time. The first installed SIS line is made the rcv line, and the next installed SIS line is made a xmt line. As each pair of lines completes its wrap, the lines are reset. The line that was the xmt line is made the rev line, and the next installed SIS line is made the new xmt line. Then the test is run on this pair of lines. This is continued until the last installed SIS line has been used as a xmt line. At this time, the last installed SIS line is made a rcv line, and the first installed line is made the xmt line; and the test is run. After the above is done with LCD
=
0, the whole process is repeated for LCD=
2, for LCD" 4, for LCD=
5, and then for LCD" 6.Note: LCD = 7 is tested in rtn X650. This test is not run if the 1st installed oscillator exceeds 1200 bits per second.
Date to be xmt and rcv for each LCD should be:
LCD

0; data=
X'2A', X'01', lind X'3E' LCD=
2; data=
X'OA', X'01', and X'1 E' LCD" 4; data - X'2A', X'01', and X'7E' LCD=
5; data = X'2A', X'01', and X'7E' LCD" 6; data = X'AA', X'01', and X'FE'The hardware should add a start bit and one or two stop bits to the xmt char according to LCD type. A PAD char (X'FF') is always xmt before the data char are xmt. The rcv line should rcv the xmt char except for the PAD char.
Note: For all error stops in this rtn, the following regs are set up:
Reg X'11'· xmt line adr (as used to set ABAR) Reg X'13'· rcv line adr (as used to set ABAR)
Reg X'14' (for errors that Indicate L2 Irpt occurred from wrong adr) contains the line adr that caused the L2 irpt.
Reg X'14' (for errors that indicate the rcv data Is bad or ICW bits 0-7 are in error) contains ICW bits 0-16 from the rcv line ICW obtained by executing input X'44'. ICW bits 8-16 (the PDF) contain the rcv data. ICW bits 0-7 are check and control flags and are always expected to be set as follows:
ICW bit O· stop bit check; should be off.
ICW bit 1
=
svc req; should be on.ICW bit 2
=
char overrun/underrun; should be off.ICW bit 3 = modem check; should be off.
ICW bit 4 = rcv line signal detector; this bit is ignored in this test.
ICW bit 5 = reserved bit; this bit is ignored in this test.
ICW bit 6 = pgm flag; this bit is ignored in this test.
ICW bit 7 = pad flag; this bit is ignored in this test.
Reg X'16' (for errors that indicate the rcv data is bad) contains the expected ICW bits 0-15 that are being tested against the contents of reg X'14'.
Reg X'16' (for errors that indicate LCD changed or PCF is bad) contains expected LCD and PCF in byte O.
The rcv line always has the display bit on in its ICW, so reg X'46' is valid for the rcv line under test. All lines are set to priority 3 and oscillator select O. Refer to notes 4,5, and 7 at the end of this symptom index for aid in problem determination. The following error codes are listed in the sequence in which the actual test is run.

the continue function to determine if only this line set, this Ll8, or all lines in the scanner are failing. If all lines are failing, the first oscillator card or the scanner cards are probably bad. If all lines in one Ll8 are failing, check the bit clock control card. If only 1 line or a pair of lines is failing, the problem is probably the line set card(s) for the failing line adr.

7. A3H2 TA211XXXX S'inc line sets wrap data test. All installed line adr that run in sync mode (!'!ven though they also run in SIS mode and have been already tested in rtn X650) are wrapped two at a time. The first installed sync line adr is made the rcv line, and the next installed sync line adr is made the xmt line adr. The test is performed on this pair of lines. When the test is completed on this pair of lines, the lines are reset; the line that was the xmt line is now made the rcv line, and the next installed sync line adr is made the new xmt line. This pair of lines is then wrapped. This stepping through the lines is continued until the last installed sync line has been the xmt line. Then the first installed line is made the xmt line, and the last installed sync line is made the rcv line; this pair of lines is wrapped. All the installed sync line sets are wrapped with LCD = C, and then the above procedure is repeated using LCD = D.
A set mode is executed for both the xmt and rcv line adr with ICW bit 27 (diag wrap mode) and ICW bit 29 (sync bit clock) on. Oscillator select bits are O's to select the first oscillator. The priority bits are set to 3. The set mode is executed before the setting of scope sync 2 as each pair of lines is wrapped. The set mode must complete successfully for the wrap to function; any errors detected during the set mode are pretest errors, and all start with error code 1 XXX. These error codes are located in "Common Error Stops" following this CSB symptom index. References to L2 irpt in the following error code displays are the char·svc L2 irpt that o~cur after scope sync 2 is set; they do not include the L2 irpt that occurred for the set modes that occur before scope sync 2.

Should have just completed xmt char X'01'. Char X'FE' should have transferred from the PDF to the SDF and be in the process of being xmt. This is the 5th L2 (3rd from xmt line adr) after setting scope sync 2. See checks and comments under X652 OX01.
See checks and comments under X652 OX01. After this error, the xmt PCF is set to '0' for turnaround.
This is the 6th L2 (3rd from rcv line adr) and last L2 irpt for rcv line. See checks and comments under X652 OX01.
See checks and comments under X652 OX01.
See comments under X652 OX07 for ICW bits.
This is the 7th L2 (4th from the xmt line adr) after pgm set scope sync 2. Xmt turnaround (PCF
=
D) was set after previous L2 for xmt line, so xmt line should now be turned around to rcv mode.(PCF
=
7).See checks and comments under X652 OX01.
When xmt turnaround is completed, the SDF should
