INSTALLATION
Raise the H2TU-C front panel. Align the H2TU-C with the shelf card-slot guides and
slide the unit in. Press down on the front panel to secure the unit in the shelf.
POWER-UPSEQUENCE
When the H2TU-C powers up, the DSL LED flashes red once every second.
If the H2TU-C is unable to communicate with the H2TU-R, the DSL LED displays
solid red, indicating HBER, MARG, or PWRF alarms.
If the H2TU-C is able to communicate with the H2TU-R, theDSL LED displays solid
green, indicating that the HDSL2 spans are synchronized without error.
Verify the presence of a DS1 signal by confirming that the ALM LED is off (not lit).
If the ALM LED displays red oryellow, a DS1LOS condition exisits. Refer to Table 2
to locate the problem.
Verify error-free DS1 transmission by confirming that the DS1, framing (ESF/SF),
and line code (B8ZS/AMI) LEDs display solid colors. Refer to Table 2 to locate the
problem if these LEDs are either flashing or display solid red.
PROVISIONING
Perform these basic provisioning tasks:
1Connect a maintenance terminal to the craft port (see front-panel illustration
inside) and log on. Press + to refresh the logon screen, if necessary.
Refer to the onscreen Help menu for navigational aids or use the (to
cycle through selections), (to activate the current setting, choice, or to
display a menu), or (to return to the parent menu), or directional
arrow keys (to navigate to a menu or item)
2Select Config, Date and Time, then type the date and time.
3Select Inventory, then type the unit ID numbers.
4Change the settings of any system parameters, if necessary, by selecting Config,
then Standard Options or ADC Options. (See Table 3 and Table 4 inside.)
Once the H2TU-C is successfully installed and provisioned, access the Monitor,
Performance, or Event Log menus to clear the Performance, Alarm History, or Event
Log screens, or use Master Clear in the Config menu.

(LBTO) Sets automatic cancellation of all loopbacks to NONE, 20 min, 60 min, or
120 min after activation.
Loop Attenuation
Threshold (LATT) Determines the maximum loop attenuation (0 to 40 dB) before an alarm is
declared. Zero disables the alarm. Default setting is 32 dB.
Margin Threshold
(MARG) Determines the minimum allowable margin (0 to 15 dB) below which a system
alarm can occur. Zero disables the alarm. Default setting is 4 dB.
DS1 Frame Formatting
(FRMG) AUTO = system searches DS1 transmission for SF or ESF frame pattern.
SF = sets system for SF frame formatting.
ESF = sets system for ESF frame formatting.
UNFR = system functions as a transparent bit pipe.
DS1 Line Coding (DS1) B8ZS = sets system for B8ZS line code.
AMI = sets system for AMI line code.
H2TU-C Equalization
(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.), or 533 (533 to 655 ft.).
H2TU-R Line Buildout
(RLBO) Sets the DS1 receive level output toward the Customer Interface to 0 dB,
-7.5 dB, or -15.0 dB.
Alarm Pattern (ALMP) Enables an AIS or LOS output at the DS1 ports for LOSW or LOS DS1.
H2TU-R TLOS Loopback
(TLOS) Enables (ENA) or disables (DIS) a TLOS loopback at H2TU-R for LOS at its
DS1 input (if enabled at the H2TU-R).
Network Loopback
Pattern (NLBP) Enables the H2TU-R to transmit an AIS or LOS towards CI for any network
loopback.
Power Back Off Network
(PBON) The power output levels of the H2TU-C network unit toward the customer.
Default (DEF) or enhanced (ENH).
Power Back Off Customer
(PBOC) The power output levels of the H2TU-R customer unit toward the network.
Default (DEF) or enhanced (ENH).

(a) Default settings are in bold.
ADC Option Function
Line Power Feed (PWRF) Enables (ON) or disables (OFF) HDSL2 line power.
Remote Provisioning
(RTPV) Enables (ENA)or disables (DIS) remote provisioning.
Bipolar Violation
Transparency (BPVT) Enables (ENA) or disables (DIS) Bipolar Violation Transparency.
DS1 BER (DBER) Enables (ENA) or disables (DIS) 24-hour DSX-1 BER alarm threshold.
HDSL2 BER Threshold
(HBER) Sets HDSL2 BER alarm threshold at 1E-6, 1E-7 or NONE.

Network AIS Pattern
(NAIS) If ALMP is set to AIS, determines 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.
Performance Report
Messaging (PRM) OFF = no enhanced Performance Report Messaging, SPRM = Supplemental
PRM, NPRM = Network PRM, S + N = H2TU-R generates both SPRMs and
NPRMs whenever possible.
RAI to RAI-CI towards
NET (RACI) Enables (ENA) or disables (DIS) conversion of a DS1 RAI signal (yellow alarm)
received by the H2TU-R to an RAI-CI signal toward the network.
ESF-RAI to SF-RAI
Overwrite (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 toward the CI at
the H2TU-R. CONV option must be set to FCON or ACON.
H2TU-R DS1 Frame
Conversion (CONV) OFF = framing determined by the DS1 FRMG option, ACON = autodetection of

INSTALLATION
Raise the H2TU-C front panel. Align the H2TU-C with the shelf card-slot guides and
slide the unit in. Press down on the front panel to secure the unit in the shelf.
POWER-UPSEQUENCE
When the H2TU-C powers up, the DSL LED flashes red once every second.
If the H2TU-C is unable to communicate with the H2TU-R, the DSL LED displays
solid red, indicating HBER, MARG, or PWRF alarms.
If the H2TU-C is able to communicate with the H2TU-R, theDSL LED displays solid
green, indicating that the HDSL2 spans are synchronized without error.
Verify the presence of a DS1 signal by confirming that the ALM LED is off (not lit).
If the ALM LED displays red oryellow, a DS1LOS condition exisits. Refer to Table 2
to locate the problem.
Verify error-free DS1 transmission by confirming that the DS1, framing (ESF/SF),
and line code (B8ZS/AMI) LEDs display solid colors. Refer to Table 2 to locate the
problem if these LEDs are either flashing or display solid red.
PROVISIONING
Perform these basic provisioning tasks:
1Connect a maintenance terminal to the craft port (see front-panel illustration
inside) and log on. Press + to refresh the logon screen, if necessary.
Refer to the onscreen Help menu for navigational aids or use the (to
cycle through selections), (to activate the current setting, choice, or to
display a menu), or (to return to the parent menu), or directional
arrow keys (to navigate to a menu or item)
2Select Config, Date and Time, then type the date and time.
3Select Inventory, then type the unit ID numbers.
4Change the settings of any system parameters, if necessary, by selecting Config,
then Standard Options or ADC Options. (See Table 3 and Table 4 inside.)
Once the H2TU-C is successfully installed and provisioned, access the Monitor,
Performance, or Event Log menus to clear the Performance, Alarm History, or Event
Log screens, or use Master Clear in the Config menu.
