Selection Description
NONE Disables automatic time-out cancellation of all loopbacks.
20 Sets automatic cancellation of all loopbacks to 20 minutes after initiation.
60 Sets automatic cancellation of all loopbacks to 60 minutes after initiation.
120 Sets automatic cancellation of all loopbacks to 120 minutes after initiation.
0 through 40 dB Determines the maximum loop attenuation before an alarm is declared. The
loop attenuation threshold can only be set through the HiGain HDSL2
maintenance screens.
35 dB Default value. Zero disables the alarm.
0 to 15 dB Determines the minimum allowable margin below which a system alarm can
occur. Zero disables the alarm.The Margin Alarm Threshold can only be set
through the HiGain HDSL2 maintenance screens.
4dB Default value.
AUTO Configures the HiGain 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
will cause the ES-P and SES-P counters to increment.
SF Configures the HiGain system to search for the SF framing pattern at its DS1
input.
ESF Configures the HiGain 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 H2TU-C-388 and H2TU-R monitor the incoming DS1 bit streams for the
B8ZS code. If the H2TU-R detects this code, the H2TU-C enters B8ZS output
mode. The H2TU-C reverts back to AMI output mode if no B8ZS codes are
received at the H2TU-R input for 5 seconds. Similarly, when the H2TU-C
detects the B8ZS code, the H2TU-R enters B8ZS mode and returns to AMI
mode if no B8ZS code is received at the H2TU-C input for 5 seconds.
B8ZS Places both the H2TU-C-388 and H2TU-R into B8ZS mode.
AMI Places both the H2TU-C-388 and H2TU-R into AMI mode.
0 Sets the Equalizer to DSX-1 for 0 to 132 feet.
133 Sets the Equalizer to DSX-1 for 133 to 265 feet.
266 Sets the Equalizer to DSX-1 for 266 to 398 feet.
399 Sets the Equalizer to DSX-1 for 399 to 532 feet.
533 Sets the Equalizer to DSX-1 for 533 to 655 feet.
0 dB Sets the DS1 receive level output toward the Customer Interface (CI). Can only
be set through the HiGain HDSL2 maintenance screens.
-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.
AIS Enables the HiGain system to output an AIS payload at its DS1 ports for LOSW
and DS1 LOS. See

LOSW and DS1 LOS.
