18 June 6, 2000 H2TU-C-388 List 1
H2TU-R TLOS
Loopback
TLOS ENA Enables a logic loopback at the H2TU-R when an LOS occurs at its DS1 input.
See Figure 25 on page 38 for LOS/AIS response priorities.
DIS Disables TLOS logic loopback.
Network
Loopback Pattern
NLBP AIS Enables the H2TU-R to transmit AIS towards the CI for any network loopback.
See Figure 25 on page 38 for LOS/AIS response priorities.
LOS Enables the H2TU-R to transmit LOS towards the CI for any network loopback.

Line Power Feed PWRF OFF Disables powering to the HDSL2 pair.
ON Keeps the HDSL2 line voltage at nominal -185 Vdc.
Remote Provisioning RTPV ENA Enables remote provisioning.
DIS Disables remote provisioning.
Bipolar Violation
Transparency
See “Bipolar
Violation
Transparency
(BPVT) Option” on
page 19.
BPVT ENA Enables BPVs and HDSL2 CRC errors at the DS1 input to be converted into
DS1 BPVs at the DS1 output at the distant end. This makes HiGain
transparent to BPVs.
DIS Disables BPV Transparency.
DS1 BER Threshold DBER ENA Enables the fixed 24-hour DS1 BER threshold.
DIS Prevents the generation of a system alarm due to DS1 BER.
HDSL2 BER
Threshold
HBER 1E-6 The Status LED flashes red when the Block Error Rate (BER) exceeds 10
-6
.
See “HDSL2 BER
Threshold (HBER)
Option” on page 19.
1E-7 The Status LED flashes red when BER exceeds 10
-7
.
NONE Prevents generation of a system alarm due to BER.
Special Loopback
Mode
SPLB GNLB Configures the HiGain system to respond to the generic inband loopback
codes.
A1LB and
A2LB
Configures the HiGain system to respond to the inband loopback codes of
the Teltrend addressable repeater.
A3LB Configures the HiGain system to respond to the inband loopback codes of
the Wescom addressable repeater.
A4LB Configures the HiGain system to respond to the inband loopback codes of
the Wescom Mod 1 addressable repeater.
A5LB Configures the HiGain system to respond to the inband loopback codes of
the Teltrend Mod 1 addressable repeater.
SmartJack Loopback LPBK ENA Enables the HiGain system to recognize all inband SmartJack (SMJK)
loopback commands.
DIS Configures the HiGain system to ignore all inband SmartJack loopback
commands.
