Selection Description
NONE Disables automatic time-out cancellation of all loopbacks.
20 min Sets automatic cancellation of all loopbacks to 20 minutes after initiation.
60 min Sets automatic cancellation of all loopbacks to 60 minutes after initiation.
120 min Sets automatic cancellation of all loopbacks to 120 minutes after initiation.
8 hr Sets automatic cancellation of all loopbacks to 8 hours after initiation.
24 hr Sets automatic cancellation of all loopbacks to 24 hours after initiation.
0 through 50 dB Determines the maximum loop attenuation before an alarm is declared. Zero
disables the alarm. The loop attenuation threshold cannot be set from the
front-panel pushbuttons.
35 dB Default value.
0 to 15 dB Determines the minimum allowable margin below which a system alarm can
occur. Zero disables the alarm. The Margin (Alarm) Threshold cannot be set
from the front-panel pushbuttons.
4dB Default value.
AUTO Configures the HDSL4 system to operate in an auto-framing (AUTO) mode. It
detects and locks to both SF or ESF DS1 frame patterns. Line and path
performance parameters are maintained and displayed. Unframed payloads
cause the ES-P and SES-P counters to increment.
SF Configures the HDSL4 system to search for the SF framing pattern at its DS1
input.
ESF Configures the HDSL4 system to search for the ESF framing pattern at its DS1
input.
UNFR Configures the same as AUTO except unframed payloads do not cause the
ES-P and SES-P counters to increment.
AUTO The H4TU-C and H4TU-R monitor the incoming DS1 bit streams for the B8ZS
code. If the H4TU-R detects this code, the H4TU-C enters B8ZS output mode.
The H4TU-C reverts back to AMI output mode if no B8ZS codes are received
at the H4TU-R input for 5 seconds. Similarly, when the H4TU-C detects the
B8ZS code, the H4TU-R enters the B8ZS mode and returns to AMI mode if no
B8ZS code is received at the H4TU-C input for 5 seconds.
B8ZS Places both the H4TU-C and H4TU-R into B8ZS mode.
AMI Places both the H4TU-C and H4TU-R into AMI mode.
0 ft Sets the Equalizer to DSX-1 for 0 to 132 feet.
133 ft Sets the Equalizer to DSX-1 for 133 to 265 feet.
266 ft Sets the Equalizer to DSX-1 for 266 to 398 feet.
399 ft Sets the Equalizer to DSX-1 for 399 to 532 feet.
533 ft Sets the Equalizer to DSX-1 for 533 to 655 feet.
Sets the DS1 receive level output toward the Customer Interface (CI). Line
buildout can only be set through the maintenance screens.
0 dB Sets the DS1 RLBO level toward the CI to 0 dB.
-7.5 dB Sets the DS1 RLBO level toward the CI to -7.5 dB.
-15 dB Sets the DS1 RLBO level toward the CI to -15.0 dB.
