Response to Query
Unit Test
Mode TST= 1 byte, value
of 0 thru 6 Command or Query.
CDM-570L Test Mode, where:
0= Normal Mode (no test)
1=IF Loopback
2=Digital Loopback
3=I/O Loopback
4=RF Loopback
5=Tx CW
6=Tx Alternating 1,0 Pattern
Example: TST=1 (IF Loopback) TST=
TST?
TST*
TST# TST? TST=x
(see description of
arguments)
Unit Alarm
Mask MSK= 12 bytes Command or Query.
Alarm mask conditions, in form abcdefghijkl, where:
a=Tx FIFO (0 = unmasked, 1 = masked)
b=G.703 BPV (0 = unmasked, 1 = masked)
c=Tx-AIS (0 = unmasked, 1 = masked)
d=Rx AGC Alarm (0 = unmasked, 1 = masked)
e=Eb/No Alarm (0 = unmasked, 1 = masked)
f=Rx-AIS
g=Buffer slip
h=Ext Reference alarm
i=BUC alarm
j=LNB alarm k=spare, l= spare MSK=
MSK?
MSK*
MSK# MSK? MSK=abcdefghijkl
(see description of
arguments)
Request to
Send RTS= 1 byte, value
of 0 thru 3 Command or Query.
Defines how RTS/CTS will operate at the main data interface
0 = RTS/CTS Loop, No Action
RTS and CTS are looped, so that CTS echoes the state of RTS, but
RTS does not control the ON/OFF state of the carrier
1 = Loop, RTS Controls Tx O/P
RTS and CTS are looped, so that CTS echoes the state of RTS, and
RTS controls the ON/OFF state of the carrier (in other words, the
modem will not bring up its TX carrier until RTS is asserted.)
2 = Ignore RTS, Assert CTS
3 = 1:N system in use. RTS/CTS ignored (Query only) RTS is
ignored, and CTS is asserted unconditionally.
Example: RTS=0 (RTS/CTS Loop, No Action). RTS=
RTS?
RTS*
RTS# RTS? RTS=x

arguments)
