20 • T1/E1 Link
Receive Equalizer (linkRxEqualizer)
This variable determines the equalization used on the received signal. Long haul signals should have the equal-
ization set for more. Short haul signals require less equalization.
•
linkRxEqualizerOff(1)
•
linkRxEqualizerOn(2)
Receiver Sensitivity (linkSensitivityLevel)
This variable selects the minimum voltage at which the WAN port will sense that the signal is available. The
default setting is
linkSensitivityLevel5
.
Note
This variable is only used if the receiver equalization is set to ON (see
“Receive Equalizer (linkRxEqualizer)”
on page 298).
•
linkSensitivityLevel1(1)—Voltage threshold: 1.70V; maximum distance achievable: less than 1,000 feet
(305 meters)
•
linkSensitivityLevel2(2)—Voltage threshold: 0.84V; maximum distance achievable: less than 2,000 feet
(610 meters)
•
linkSensitivityLevel3(3)—Voltage threshold: 0.84V; maximum distance achievable: less than 3,000 feet
(914 meters)
•
linkSensitivityLevel4(4)—Voltage threshold: 0.45V; maximum distance achievable: less than 5,000 feet
(1,524 meters)
•
linkSensitivityLevel5(5)—Voltage threshold: 0.45V; maximum distance achievable: less than 5,000 feet
(1,524 meters)
•
linkSensitivityLevel6(6)—Voltage threshold: 0.2V; maximum distance achievable: less than 5,000 feet
(1,524 meters)
•
linkSensitivityLevel7(7)—Voltage threshold: 0.1V; maximum distance achievable: less than 5,000 feet
(1,524 meters)
Line Build Out (linkLineBuildOut)
This variable defines the T1 or E1 pulse levels used by the T1/E1 ports:
•
triState(0)—When the T1/E1 port is not in use, the user may want to place the port in tri-state mode.
While in this setting, the input lines to the port are placed in high impedance protection mode.
•
e1pulse(1)—Used when connecting the T1/E1 port to E1 lines.
•
t1pulse0dB(2)—Strong T1 pulse amplitude.
•
t1pulse-7dB(3)—Medium T1 pulse amplitude.
•
t1pulse-15dB(4)—Weak T1 pulse amplitude.
Yellow Alarm Format (linkYellowFormat)
This variable identifies which standard will be used to transmit and identify the Yellow Alarm.
•
link YellowFormatBit2(1)—Bit-2 equal zero in every channel
