(a) Front-panel alarm messages are listed in order of priority.
Pressing the LBK pushbutton initiates an Alarm Cutoff (ACO) message.
(b) Message displays repeatedly as long as the alarm condition exists and is not included in the priority order.
Table 2. Front-Panel System Information Messages (Scroll Mode)
Code Description
VER x.xx Firmware version.
LIST xx Product list number.
FRM xxxx Frame pattern received from the
DSX-1 (SF, ESF, or UNFR).
(a) To scroll through system information messages, press the MODE pushbutton for 3 or more seconds.
Table 3. Front-Panel Configuration Options Using MODE and SEL
Display Code Description (default values in bold)
EQL Sets the DSX-1 Equalizer to: 0 (0 to 132 ft.), 133 (133 to 265 ft.), 266 (266 to 398 ft.),
399 (399 to 532 ft.), or 533 (533 to 655 ft.).
RLBO Sets the H2TU-R line buildout to 0 dB, -7.5 dB, or -15 dB.
LPBK Enables (ENA) or disables (DIS) SmartJack loopback commands.
SPLB xxxx Configures system for generic (GNLB) or special in-band loopback commands (A1LB, A2LB, A3LB, A4LB,
or A5LB).
PWRF OFF = disables HDSL2 powering; ON = HDSL2 line voltage is -180 Vdc maximum.
HBER 1E-6 or 1E-7 = alarm activates when the HDSL2 BER alarm threshold exceeds 10
NONE = prevents generation of a system alarm due to BER.
DBER Enables (ENA) or disables (DIS) fixed 24-hour DS1 BER alarm threshold.
LBTO Loopback timeout = NONE, 20, 60, or 120 minutes or 8 or 24 hours.
DS1 DSX-1 line code = AUTO, B8ZS, or AMI.
FRMG DS1 frame formatting = AUTO (Auto framing mode), SF (SuperFrame), ESF (Extended
SuperFrame), or UNFR (Unframed mode).
RDA Enables (ENA) or disables (DIS) alarm indications due to remote DS1 LOS at H2TU-R input.
ALMP Enables system to output an alarm pattern: AIS or LOS.
BPVT Enables (ENA) or disables (DIS) Bipolar Violation Transparency.
NLBP Enables the H2TU-R to transmit either AIS or LOS towards CI for any network loopback.
TLOS Enables (ENA) or disables (DIS) a logic loopback at the H2TU-R when an LOS occurs at its DS1
input.
RTPV Enables (ENA) or disables (DIS) remote provisioning.
PBON Configures the power output levels of the H2TU-C network unit toward the customer to comply
with Default (DEF) or Enhanced (ENH) templates.
PBOC Configures the power output levels of the H2TU-C customer unit toward the network to comply
with Default (DEF) or Enhanced (ENH) templates.
(a) Front-panel configuration options display in the order listed.
Table 1. Front-Panel Alarm Messages
Description
A short between the Tip and Ring of the HDSL2 pair.
The HDSL2 loop is grounded.
A line-power open condition.
The HDSL2 loop has lost synchronization.
No signal is detected at the DSX-1 input to the H2TU-C.
No signal is detected at the DS1 input to the H2TU-R.
Line Alarm Indication Signal.
Remote Alarm Indication Signal.
An RAI alarm (yellow) from the CPE without errors from the line unit or network.
An RAI alarm (yellow) from the CPE with errors from the line unit or network.
The DS1 input does not contain the ESF or SF frame pattern setting of the FRMG option.
(xxx denotes either Transmission Unit Central Office [TUC] or Transmission Unit
Remote End [TUR].)
A system DS1 Bit Error Rate (BER) alarm. (xxx denotes either TUC or TUR.)
H2TU-R Performance Report Messaging BER threshold exceeded at far end.
H2TU-R Performance Report Messaging BER threshold exceeded at near end.
A system HDSL2 Block Error Rate (BER) alarm. (xxx denotes either TUC or TUR.)
The margin on the HDSL2 loop has dropped below the threshold setting. (xxx denotes
either TUC or TUR.)
The attenuation on the HDSL2 loop has exceeded the maximum threshold value.
(xxx denotes either TUC or TUR.)
displays prior to any alarm message.
