(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.

Message Function
VER x.xx Software version number of the H2TU-C.
LIST xx List number of the H2TU-C.
FRM xxxx Frame pattern received from the DSX-1 (SF, ESF, or UNFR).
CODE xxxx Line code (AMI or B8ZS).
LATT xx Loop attenuation threshold setting (38).
MARG xx Margin threshold setting (4).
EQL Sets the DSX-1 equalizer to: EXT (External), 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 H2TU-R line buildout to DS1 is set 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 inband loopback commands (A1LB, A2LB, A3LB, A4LB, or
A5LB).
PWRF OFF = disables line power; ON = -180 Vdc.
HBER 1E-6 or 1E-7 = indicates HDSL2 BER alarm threshold setting. NONE = no generation of a system
alarm due to BER.
DBER Enables (ENA) or disables (DIS) fixed 24-hour DSX-1 BER alarm threshold.
LBTO Loopback timeout = NONE, 20 min, 60 min, 120 min, 8-hour, or 24-hour.
DS1 DSX-1 line code = B8ZS or AMI.
CONV H2TU-R frame format conversion = OFF (framing determined by the DS1 FRMG option),
ACON (autodetection of framing and potential frame conversion at the H2TU-R), or
FCON (autodetection of framing and forced frame format conversion at the H2TU-R).
FRMG DS1 frame formatting = AUTO (automatic framing), SF (SuperFrame), ESF (Extended SuperFrame),
or UNFR (unframed).
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: Alarm Indication Signal (AIS) or Loss of Signal (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.
PRM OFF = no enhanced Performance Report Messaging; SPRM = Supplemental PRM;
NPRM = Network PRM; AUTO = SPRM + NPRM.
NAIS If ALMP is set to AIS, this option specifies which pattern is sent to the network when a remote LOS
or AIS occurs. CI = AIS-CI sent to the network; AIS = AIS sent to the network.
ROVR Enables (ENA) or disables (DIS) conversion of an ESF DS1 payload from the network with an
embedded RAI pattern to an SF-RAI pattern towards the CI at the H2TU-R. CONV option must be
set to FCON or ACON.
RACI Enables (ENA) or disables (DIS) conversion of a DS1 SF-RAI signal received by the H2TU-R to an
SF-RAI-CI signal towards the network.
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-R customer unit toward the network to comply with
Default (DEF) or Enhanced (ENH) templates.
(a) Front-panel codes scroll in the order listed. The configured selections follow each code.
(b) Default values are in bold.
