ADC HiGain H2TU-C-319 List 6 Quick Installation page 6

Message Description (normal operating messages in bold)
A=xx The loop attenuation of the longest (maximum loss) span, measured in dB.
ACQ The multiplexers of the H2TU-C-319 and H2TU-R are trying to establish synchronization.
AnL The multiplexers of the two devices on Span n are trying to establish synchronization with
each other, where n is the number of the span.
ARM Armed to respond to Intelligent Repeater Loop (ILR) codes.
BAD RT? The H2TU-C is not receiving a response from the H2TU-R.
FERR A framing bit error occurred at H2TU-C DSX-1 input.
FLDL Flash download of firmware upgrades. (Contact Customer Service for upgrade
procedures.)
HES H2TU-C HDSL2 loop cyclical redundancy check (CRC) error.
LBPV A local bipolar violation has been received at the DSX-1 input to the H2TU-C.
M=xx Indicates the power of the received HDSL2 signal relative to noise (S/N with respect to
21.5 dB). Any value of 6 dB or greater is adequate for reliable system operation.
MNGD The H2TU-C is under control of the HMU-319 network management unit.
PWR FEED OFF HDSL2 span power is turned off.
PWR FEED ON Indicates that the HDSL2 loop is not grounded or shorted.
SIG The transceivers of the H2TU-C and H2TU-R are trying to establish contact with each
other on Span 1 of the HDSL2 loop.
SnL The transceivers of the two devices on Span n are trying to establish contact with each
other, where n is the number of the span.
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.), 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 inband loopback commands (A1LB, A2LB, A3LB,
A4LB, A5LB).
PWRF OFF = disables HDSL2 powering; ON = HDSL2 line voltage is -185 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, 120 minutes.
ALM Enables (ENA) or disables (DIS) alarm indications on pin H.
DS1 DSX-1 line code = AUTO, B8ZS, 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.
