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 Determines the maximum loop attenuation before an alarm is declared. Zero
40 dB disables the alarm. The loop attenuation threshold can only be set through
the HDSL2 maintenance screens.
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 can only be
set through the HiGain HDSL2 maintenance screens.
4dB Default value.
AUTO Configures the HiGain HDSL2 system to operate in an auto-framing (AUTO)
mode in which it continuously searches the input DS1 bit stream for a valid
SF or ESF frame pattern. Both line and path performance parameters are
maintained.
UNFR Configures the HiGain HDSL2 system to operate in an unframed mode. This
mode disables the auto framing process and forces the system to function
as a transparent bit pipe. Only line parameters are considered when
monitoring DS1 performance.
AUTO The H2TU-C-202 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 the 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 and H2TU-R into their B8ZS modes.
AMI Places both the H2TU-C and H2TU-R into their AMI modes.
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.
DSX Sets the DS equalizer toward the Customer Interface (CI) to the DSX-1
zero-foot equalization level.
0 dB Sets the DS1 RLBO level toward the Customer Interface (CI) to 0 dB. H2TU-R
Line Buildout can only be set through the HDSL2 maintenance screens.
-7.5 dB Sets the DS1 RLBO receive level toward the CI to - 7.5 dB.
-15.0 dB Sets the DS1 RLBO receive level toward the CI to - 15.0 dB.
AIS Enables the HiGain HDSL2 system to output an AIS payload at its DS1 ports
for LOSW and DS1 LOS. For priority resolution, see
