Table B-4 DATA Port Signal Overview
Item Specification
DSR/DM Line The DSR line is dropped when a test is performed to
prevent use of the unit for payload traffic. The
DATA Port
is asserted unless one of following is true:
¥ DSU or CSU Loopback
¥ Loop Up Remote Test
¥ Loop Down Remote Test
¥ Self Test in progress
¥ DSU performing pattern test
TM Line The TM line to the
DATA Port is asserted if one of
following tests is running:
¥ DSU or CSU Loopback
¥ Loop Up Remote Test
¥ Loop Down Remote Test
¥ DSU performing pattern test
CTS Line The CTS line is asserted if DTE is not lost (RTS or DTR
asserted if enabled), if no Out of Frame alarm is received
from the network indicating the remote unit cannot receive
transmitted signal and when no test (other than DTE
Loopback) is running. To enable the test equipment to send
a test signal—CTS is asserted in DTE Loopback.
RLSD/RR Line The RLSD line drops to indicate the received line data is
not valid payload traffic. (Includes cases when DSR is not
asserted, indicating a test is running and is preventing the
unit from carrying customer data.)
