Description
Loopback
Timeout
LBTO
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.
Loop Attenuation
Threshold
LATT
0 through
40 dB
Determines the maximum loop attenuation before an alarm is declared. Zero
disables the alarm. The loop attenuation threshold can only be set through the
HiGain maintenance screens.
32 dB
Default value.
Margin Threshold
MARG
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 maintenance screens.
5 dB
Default value.
DS1 Frame
Formatting
FRMG
AUTO
Configures the HiGain HDSL2 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.
UNFR
Configures the same as AUTO except unframed payloads do not cause the
ES-P and SES-P counters to increment.
DS1 Line Coding
DS1
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.
H2TU-C
Equalization
See
Equalization
(EQL) Option.” on
page 22
EQL
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.
H2TU-R Line
Buildout
RLBO
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 level toward the CI to -7.5 dB.
-15.0 dB
Sets the DS1 RLBO level toward the CI to -15.0 dB.
Alarm Pattern
See
Pattern (ALMP)
Option.” on
page 22
ALMP
AIS
Enables the HiGain HDSL2 system to output an AIS payload at its DS1 ports
for LOSW and LOS DS1. For priority resolution, see
LOS
Enables the HiGain HDSL2 system to output an LOS condition at its DS1 ports
for LOSW and LOS DS1.
H2TU-R TLOS
Loopback
TLOS
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.
Network
Loopback Pattern
NLBP
AIS
Enables the H2TU-R to transmit an AIS towards CI for any network loopback.
For priority resolution, see
LOS
Enables the H2TU-R to transmit an LOS towards CI for any network loopback.
