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 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
maintenance screens.
38 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 maintenance screens.
4 dB Default value.
AUTO Configures the 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.
Unframed payloads will cause the ES-P and SES-P counters to increment.
UNFR Configures the 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.
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.
EXT Disables the H2TU-C internal equalizer, allowing connection of external
equalizer hardware.
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). H2TU-R
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 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 HDSL2 system to output an AIS payload at its DS1 ports for LOSW
and DS1 LOS. For priority resolution, see
LOS Enables the HDSL2 system to output an LOS condition at its DS1 ports for
LOSW and DS1 LOS.
ENA Enables a logic loopback at the H2TU-R when an LOS occurs at its DS1 input, if
enabled at the H2TU-R. For priority resolution, see
DIS Disables Transmit Loss of Signal (TLOS) logic loopback.
