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 and H2TU-R are trying to establish synchronization.
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 updates. (Contact Customer Service for update 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 span power is turned on and the 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.
Message Description (default selections in bold)
Software version number of the H2TU-C-319.
VER x.xx
LIST xx List number of the H2TU-C-319.
FRM xxxx Frame pattern received from the DSX-1 (SF, ESF, UNFR).
CODE xxxx Line code (AMI or B8ZS).
LATT xx Loop Attenuation threshold setting (38).
MARG xx Margin threshold setting (4).
EQL Indicates DSX-1 Equalizer setting: 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 Indicates H2TU-R line buildout setting: 0 dB, -7.5 dB, or -15 dB.
LPBK SmartJack loopback commands enabled (ENA) or disabled (DIS).
SPLB xxxx System configured for generic (GNLB) or special inband loopback commands (A1LB, A2LB, A3LB, A4LB,
A5LB).
PWRF HDSL2 line power disabled (OFF) or -180 Vdc (ON).
HBER 1E-6 or 1E-7 = indicates HDSL2 BER alarm threshold setting. NONE = no generation of a system
alarm due to BER.
DBER 24-hour DSX-1 BER alarm threshold enabled (ENA) or disabled (DIS).
LBTO Loopback timeout = NONE, 20, 60, 120 minutes, 8-hour, 24-hour.
DS1 DSX-1 line code = Bipolar with 8-Zero Substitution (B8ZS), Alternate Mark Inversion (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 (auto framing mode) or UNFR (unframed mode),
RDA Alarm indications due to remote DS1 LOS at H2TU-R input are enabled (ENA) or disabled (DIS).
ALMP Alarm pattern = Alarm Indication Signal (AIS) or Loss of Signal (LOS).
BPVT Bipolar Violation Transparency (BPVT) enabled (ENA) or disabled (DIS).
NLBP H2TU-R transmits either AIS or LOS towards CI for any network loopback.
TLOS Logic loopback at the H2TU-R is either enabled (ENA) or disabled (DIS) when an LOS occurs at its
DS1 input.
PRM Performance Report Messaging = OFF (no enhanced Performance Report Messaging), SPRM
(Supplemental PRM), NPRM (Network PRM), AUTO (H2TU-R generates both SPRMs and NPRMs
whenever possible).
NAIS If ALMP is set to AIS, indicates 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 Conversion of an ESF DS1 payload from the network with an embedded RAI pattern to an SF-RAI
pattern toward the CI at the H2TU-R is enabled (ENA) or disabled (DIS). CONV option must be set
to FCON or ACON.
RACI Conversion of a DS1 SF-RAI signal (yellow alarm) received by the H2TU-R to an SF-RAI-CI signal
toward the network is enabled (ENA) or disabled (DIS).
PBOC Indicates the power output levels of the H2TU-R customer unit toward the network. Default (DEF)
or enhanced (ENH).
PBON Indicates the power output levels of the H2TU-C network unit toward the customer. Default (DEF)
or enhanced (ENH).
