DSU Port Configuration Options
LSD Lead: Std
Next Std Delay FrcOn Prev
Line Signal Detect Lead. Controls behavior of the Line Signal Detect lead.
Std — LSD lead goes Off in response to a control mode idle (CMI) signal from the DDS network or DDS failure.
Delay — LSD does not go Off in response to a network alarm condition or CMI. LSD goes Off only after a
successful backup connection is established.
FrcOn — Keeps LSD on as long as the DSU has power.
DSR FrcOn: Enab
Next Enab Disab Prev
Data Set Ready Forced On. Provides the ability to override any other options controlling the Data Set Ready lead.
Enab — DSR remains ON as long as the device is working, regardless of tests and network alarms.
Disab — DSR functions as an active lead reflecting various test and alarm conditions and other options.
SystemStat: Enab
Next Enab Disab Prev
System Status. Controls the behavior of the DSR lead in response to a No Signal, Out-of-Service, or Out-of-Frame alarm
from the network.
Enab — Network alarm turns Off DSR.
Disab — Network alarm does not affect DSR.
DSR on Tst: Enab
Next Enab Disab Prev
Data Set Ready On in Test. Controls the behavior of the DSR lead during testing.
Enab — DSR is ON continuously during testing, allowing a DTE that relies on DSR being ON to send test
messages to the DSU.
Disab — DSR is Off during testing.
Circ Assur:Disab
Next Enab Disab Prev
Circuit Assurance. Controls behavior of the CTS lead in response to a data signal from the network. If CTS Cntrl is set to
RTS and RTS Cntrl is set to FrcOn, this configuration option is ignored.
A DDS Facility Alarm condition turns Off the CTS lead, regardless of the Circuit Assurance setting.
Enab — The DSU will turn Off the CTS lead if the DSU receives control mode idle (CMI) from the network.
Disab — The DSU is not affected by the receipt of CMI.
RespondRDL:Disab
Next Enab Disab Prev
Respond to Remote Digital Loopback. Determines whether the DSU responds to a V.54 Remote Loopback request.
Enab — Performs a Digital Loopback.
Disab — Ignores the Loopback command.
