- HELP
EVDEC is the second of six level 3 diagnostics designed to perform static and
functional testing of the DV11 Communications Multiplexer. EVDEC exercises
all existing line cards in the static state (microprocessor OFF). Transmitter/
Receiver flags/data, Receiver sync and the character silo are tested. Most
tests exercise a "group" of four lines at a time (00-03,04-07,08-11,12-15).
For ease of troubleshooting, only one line card is installed at a time, and
by alerting the diagnostic as to which line cards are removed the program
will run any combination of line cards. PLEASE NOTE: If Parity is enabled,
make sure that the sync characters selected have the correct parity! Also,
EVDEC does not test half-duplex configurations.
- ATTACH
DS> ATT DW780 SBI DW0 3 4 ; attaches UBA TO 11/780
OR
DS> ATT DW750 CMI DW0 ; attaches UBA to 11/750
OR
DS> ATT DW730 HUB DW0 ; for 11/730
The following is an example of attaching a DV11:
DS> LOAD EVDEC ; LOAD DIAGNOSTIC
DS> ATT DV11 DW0 DVA0 0 775000 470 5; Attach DV11 to UBA w/logname DVA(n),
; unit #(0-7),address,vector,priority.
; ATTACH M7839 LINE CARD(S):
DS> ATT M7839 ;(REPEAT FOR EACH SYNCHRONOUS LINE CARD)
DEVICE LINK? DVA0 ; DV11 Logical name of DVA(n)
DEVICE NAME? LC0 ; Logical name of line card (LC0-LC3)
LINE_CARD? 0 ; Physical line # (0-3)
SYNCA? 226 ; Sync Character "A"
SYNCB? 62 ; Sync Character "B"
CHAR_SIZE? 8 ; Number of bits/character (5-8)
PARITY? NO ; Parity (YES,NO)
EVEN? NO ; Even (YES,NO), NO=odd parity
2SYNCS? YES ; Two sync characters (YES,NO),NO=one
LINE0? YES ; Active lines (YES,NO) : actual line
LINE1? YES ; selection not supported by EVDEC.
LINE2? YES ;
LINE3? YES ;
; ATTACH M7833 LINE CARD:
DS> ATT M7833 ;(REPEAT FOR EACH ASYNCHRONOUS LINE CARD)
DEVICE LINK? DVA0 ; DV11 Logical name of DVA(n)
DEVICE NAME? LC1 ; Logical name of line card (LC0-LC3)
LINE_CARD? 1 ; Physical line # (0-3)
LINE0? YES ; Active lines (YES,NO) : actual line
LINE1? YES ; selection not supported by EVDEC
LINE2? YES ;
LINE3? YES ;
