(a)
Message Description
A=xx The Attenuation (A) message appears followed by xx, where xx is the highest loop
attenuation of all HDSL interfaces.
ACQ1 or ACQ2 The multiplexers of the H4TU-C and H4TU-R are trying to establish synchronization over
HDSL4 Loop 1 or Loop 2.
ARM Armed to respond to Intelligent Repeater Loop (ILR) codes.
BAD RT? The H4TU-C is not receiving a response from the H4TU-R.
FERR A framing bit error occurred at H4TU-C DSX-1 input.
HxES H4TU-C Loop 1 or Loop 2 Cyclical Redundancy Check (CRC) error. (Loop 1 has display
priority over Loop 2.)
LBPV A local bipolar violation has been received at the DSX-1 input to the H4TU-C.
1=xx or The power of the received HDSL4 signal on each loop relative to noise (S/N with respect
2=xx to 21.5 dB). (xx denotes lowest margin in dB for Loop 1 and Loop 2.)
MNGD The H4TU-C is under control of the HMU-319 network management unit.
PWR FEED OFF HDSL4 span power is turned off.
PWR FEED ON HDSL4 loop is not grounded or shorted.
SIG1 or SIG2 H4TU-C and H4TU-R transceivers are trying to establish contact with each other over
HDSL4 Loop 1 or Loop 2.
(a) Normal operating messages are in bold.
Table 4. 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 H4TU-R line buildout to 0 dB, -7.5 dB, or 15 dB.
LPBK Enables (ENA) or disables (DIS) SmartJack loopback commands.
PWRF OFF = disables HDSL4 powering; AUTO = -185 Vdc or ±123 Vdc (depending on number of
downstream units detected); LOW = -185 Vdc; and HIGH = ±123 Vdc.
HBER 1E-6 or 1E-7 = alarm activates when the HDSL4 BER alarm threshold exceeds 10
NONE = prevents 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, 60, 120 minutes, 8 hr, and 24 hr.
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 the H4TU-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 H4TU-R to transmit either AIS or LOS towards CI for any network loopback.
TLOS Enables (ENA) or disables (DIS) a logic loopback at the H4TU-R when an LOS occurs at its
DS1 input.
RTPV Enables (ENA) or disables (DIS) remote provisioning.
PBOC Configures the power output levels of the H4TU-R customer unit toward the network.
Default (DEF) or enhanced (ENH).
PBON Configures the power output levels of the H4TU-C network unit toward the customer.
Default (DEF) or enhanced (ENH).
