FCC Class A Compliance
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.

H2TU-C-202 LIST 4E
The HiGain H2TU-C-202 List 4E functions as the Central Office (CO) end of a
repeaterless T1 Transmission system when connected to a HiGain HDSL2 remote unit
(H2TU-R). Setting new standards for interoperability and efficiency, HiGain HDSL2
modules transmit a 1.544 Mbps T1 payload on one unconditioned copper pair over the
full Carrier Service Area (CSA) range.

INSTALLATION
To ensure proper installation of the H2TU-C, align the unit with the enclosure slot
guides and slide it in until it touches the backplane card-edge connector.
POWER-UP SEQUENCE
When the H2TU-C powers up, the four status LEDs illuminate and report status
messages.
If the H2TU-C is able to communicate with the H2TU-R, the following occurs:
1The LOOP Status LED flashes green while acquiring each device in the system,
and turns a steady green when the entire system is operating without any alarms.
(The DS1 signal must be present.)
2If any alarm conditions exist after the system powersup, these are reported on the
appropriate status LED (see the descriptions of the four status LEDs on the
front-panel illustration inside).
PROVISIONING
After installing the H2TU-C, perform these basic provisioning tasks by accessing the
HiGain HDSL2 logon screen. Refer to the onscreen Help menu for navigational aids.
1Connect a maintenance terminal to the craft port (see front-panel illustration
inside) then press + to refresh the logon screen, if necessary.
2Select the Config menu, Date and Time, then type the date and time.
3Select the Inventory menu, then type in the unit ID numbers.
4Change the settings of any system parameters, if necessary, by selecting the
Config menu, Standard Options or ADC Options.
5Once 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.

SMJK 11000 DSX-1 signal is looped back to the network at the H2TU-R SmartJack module. CREM 1111110 DS1 signal from customer is looped back to the customer at the H2TU-C. CLOC 1111100 DS1 signal from customer is looped back to the customer at the H2TU-R. Loopdown 11100 Deactivates any of the above loopbacks.
Configuration Options Using Maintenance Terminal
Option 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. FT1 Enables (ENA) or disables (DIS) system response to DDS latching loopback commands for
fractional T1 applications.
SPLB xxxx Configures system for generic (GNLB) or special inband loopback commands (A2LB, A3LB, A4LB). PWRF OFF = disables HDSL2 powering; ON = HDSL2 line voltage is -180 Vdc. HBER 1E-6 or 1E-7 = alarm activates when the HDSL2 BER alarm threshold exceeds10-6 or 10-7. 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. ALM Enables (ENA) or disables (DIS) alarm indications on pins 22 and 30. MARG Determines the minimum allowable margin below which a system alarm can occur: (5 dB) 0 dB to
-15 dB.
DS1 DSX-1 line code = B8ZS, 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). 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.
LATT Loop Attenuation Threshold (0 - 40 dB). Default = 32 dB. 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, NAIS 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 DS1 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.
PBON Configures the power output levels of the H2TU-C network unit toward the customer to comply
with Default (DEF) or Enhanced (ENH) templates.
PBOC Configures the power output levels of the H2TU-C customer unit toward the network to comply
with Default (DEF) or Enhanced (ENH) templates.

H2TU-C-202 LIST 4E
The HiGain H2TU-C-202 List 4E functions as the Central Office (CO) end of a
repeaterless T1 Transmission system when connected to a HiGain HDSL2 remote unit
(H2TU-R). Setting new standards for interoperability and efficiency, HiGain HDSL2
modules transmit a 1.544 Mbps T1 payload on one unconditioned copper pair over the
full Carrier Service Area (CSA) range.

INSTALLATION
To ensure proper installation of the H2TU-C, align the unit with the enclosure slot
guides and slide it in until it touches the backplane card-edge connector.
POWER-UP SEQUENCE
When the H2TU-C powers up, the four status LEDs illuminate and report status
messages.
If the H2TU-C is able to communicate with the H2TU-R, the following occurs:
1The LOOP Status LED flashes green while acquiring each device in the system,
and turns a steady green when the entire system is operating without any alarms.
(The DS1 signal must be present.)
2If any alarm conditions exist after the system powersup, these are reported on the
appropriate status LED (see the descriptions of the four status LEDs on the
front-panel illustration inside).
PROVISIONING
After installing the H2TU-C, perform these basic provisioning tasks by accessing the
HiGain HDSL2 logon screen. Refer to the onscreen Help menu for navigational aids.
1Connect a maintenance terminal to the craft port (see front-panel illustration
inside) then press + to refresh the logon screen, if necessary.
2Select the Config menu, Date and Time, then type the date and time.
3Select the Inventory menu, then type in the unit ID numbers.
4Change the settings of any system parameters, if necessary, by selecting the
Config menu, Standard Options or ADC Options.
5Once 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.
Continued
To comply with the intrabuilding wiring requirements of
GR-1089 CORE, Section 4.5.9, the shields of the
ABAM-type cables that connect the H2TU-C-202 List 4E
DSX-1 output ports to the cross-connect panel must be
grounded at both ends.
