Data Communication Interfaces
DATA COMMUNICATION INTERFACES
To conduct a Data or Mux test, you must connect the data
circuit under test to the INTERCEPTOR 147 using one of
the data interfaces. During a Data or Mux test, Data
communication interface leads are activated. This appendix
includes definitions of the control and data interface leads,
a listing of which interfaces use which leads, the pin
assignments for the Data interface connectors and cables,
and figures showing which control and data leads are used
depending on setup selections.
B.1 DATA COMMUNICATION LEADS
The Data communication interface leads that can be used
are listed below.
RTS Request to Send
LL Local Loop (Loops up the closest DCE.)
RL Remote Loop (Loops up the farthest DCE.)
DTR Data Terminal Ready
CTS Clear to Send
TM Test Mode
RLSD Received Line Signal Detector
DSR Data Set Ready
RS Request to Send
CS Clear to Send
TR Terminal Ready
RR Receiver Ready
DM Data Mode
B.2 LEADS USED ON INTERFACES
For a summary showing the data communication interface
leads that flow between a Data Terminal Equipment
(DTE) and Data Circuit-terminating Equipment (DCE),
see Figure B-1. In Figure B-1, the clock and data leads are
shown first, and then the control leads.
