The Bantam 210 jack provides bidirectional communication
between the H2TU-C and a maintenance terminal
for access to maintenance, provisioning, and
performance screens. Use jack adapter 120-1035-01
to connect a standard 9-pin terminal cable between the
serial port on a PC and the H2TU-C craft port.

System option buttons (for manual setting of
system parameters)
Use MODE and SEL to manually modify user options,
initiate loopbacks, and display DSX-1 line parameters.
1 Press the MODE button for 1 second and release.
The front panel alternately displays the first
system parameter and its current setting.
2 Press SEL to step through all possible system
settings for the displayed parameter.
3 Press MODE to update the parameter and advance
to the next parameter.
4 After scrolling through all the parameters, press SEL
to confirm changes when prompted with a CONF NO
message, or press MODE to cancel all changes.
Display Code 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-388 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 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 ON Indicates that the HDSL2 loop is not grounded or shorted.
PWR FEED OFF HDSL2 span power is turned off.
SIG The tranceivers of the H2TU-C and H2TU-R (or the H2TU-C and first regenerator) are
trying to establish contact with each other on Span 1 of the HDSL2 loop.
SnL The tranceivers 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 133 ft.), 133 (133 to 266 ft.), 266 (266 to 399 ft.),
399 (399 to 533 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.
FT1 Enables (ENA) or disables (DIS) system response to DDS latching loopback commands
for fractional T1 applications.
SPLB xxxx Configures the system for generic (GNLB) or special inband loopback commands (A2LB,
A3LB, A4LB).
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 DSX-1 BER alarm threshold.
LBTO Loopback timeout = NONE, 20, 60, 120 minutes.
DS1 DSX-1 line code = B8ZS or AMI.
CONV H2TU-R frame format conversion = OFF (framing determined by the DS1 frame formatting
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).
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 the 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.
PRM OFF = no enhanced Performance Report Messaging; SPRM = Supplemental PRM;
NPRM = Network PRM; S + N = 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 T1 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.
