The H4TU-C-319 List 1 is the Central Office (CO) side of a T1 transmission system. The ADC® four-wire HDSL2
product family (hereafter referred to as “HDSL4”) is based on the HDSL4 standard ANSI T1.418 Issue 2.
The H4TU-C, when used with an H4TU-R remote unit, transmits a 1.544 Mbps payload up to a maximum distance
of 12 kft. over two unconditioned copper pairs. Using two doublers (H4Ds), the Carrier Service Area (CSA) reach
can be extended to a maximum of 34 kft. The H4TU-C-319 List 1 is designed to mount in 3192 mechanics shelves.
For a list of compatible shelves see “Appendix C - Compatibility” on page 65.

APPLICATIONS
HDSL4 systems provide a cost-effective, easy-to-deploy method for delivering T1 High Capacity Digital Service
(HCDS) over two pair of wires. HDSL4 systems support a multitude of network connections.
•The service is deployed over two unconditioned, non-loaded copper pair at 784 kps per loop.
•Conventional, inline DS1 repeaters are no longer required.
•Cable pair conditioning, pair separation, and bridged tap removal are not required.
For Span 1, each loop has no more than 47 dB of insertion loss (INSL) at 196 kHz, with driving and terminating
impedances of 135Ω; for Span 2 and Span 3, each loop has no more than 43 dB of insertion loss at 196 kHz. In
general, HDSL4 systems:
•Operate effectively in the same cable binder group with other HDSL4 lines, HDSL, T1, ADSL, SDSL, POTS,
Digital Data Service (DDS), and other transmission schemes.
•Can be used with customers requiring DS1 service on a temporary or permanent basis.
•Provide a means of quickly deploying service in advance of fiber-optic transmission systems.

LTPH-UM-1031-03, Issue 3Installation
VERIFICATION
Once the H4TU-C is installed, verify that it is operating properly. To do this, monitor the following:
•Status LED
•Status messages reported by the front-panel display (see Table 2 on page 5)
Verification without a Downstream Device
If there is no downstream device installed:
1Verify that the H4TU -C powers up. The front-panel display illuminates and reports status messages. (See
Table 2 on page 5 for a list of messages.)
2Verify that the H4TU-C attempts to communicate with downstream devices (status LED flashes red). Even
if a downstream device is not present, the following events should occur:
aThe front-panel display reports various four-character status messages.
bThe H4TU-C again attempts communication until a downstream device is detected.
Verification with a Downstream Device
If a downstream device has been installed:
1Verify that the H4TU-C powers up. (The front-panel display illuminates and reports various status messages.)
2Verify that the H4TU-C attempts to communicate with downstream devices (status LED flashes red). One of
the following occurs:
•If downstream devices are successfully identified and the HDSL4 loop synchronizes, the H4TU-C status
LED lights steady green. The H4TU-C reports normal margin and loop attenuation messages on the
front-panel display.
•If downstream devices are not successfully identified, the H4TU-C reports four-character status
messages. The H4TU-C attempts communication again and reports four-character status messages. The
H4TU-C repeats this cycle until a downstream device is detected.
3If there is more than one span, verify that each subsequent span synchronizes normally by monitoring the
front-panel display messages.
4If a remote unit is installed, verify that the last span synchronizes normally. The H4TU-C status LED should
light a steady green and the front-panel display should report normal margin messages.
5Verify that a valid DS1 signal has been applied to the H4TU-C and the H4TU-R.
•If no DS1 signal is being applied to either the H4TU-C or the H4TU-R inputs, then the appropriate DS1
alarms (LLOS or RLOS) display on the front panel and the status LED flashes red.
•If a valid DS1 signal is being supplied to the H4TU-C and H4TU-R, then DS1 alarm indications should
be absent and the status LED should be steady green.
H4TU-C-319 List 1September 12, 2003 9
Provisioning LTPH-UM-1031-03, Issue 3
PROVISIONING
There are two methods for provisioning:
•Use the MODE and SEL pushbuttons on the front panel of the H4TU-C to:
—Set system options
—Reset the H4TU-C to its factory default settings for system options
—Display system option settings (scroll mode)
—Select system loopbacks
•Use a maintenance terminal (ASCII terminal or a PC running terminal emulation software) connected to the
H4TU-C craft port (or to an HMU craft port) to access the maintenance screens (Figure 3 on page 13). This
gives you full access to all H4TU-C status, history, inventory, and provisioning screens.
The MNGD message displays if the H4TU-C-319 is under HMU management. When this occurs,
the front-panel pushbuttons and craft port are disabled.
No dip switches or jumpers are required to provision the H4TU-C-319 as it contains a
non-volatile RAM (NVRAM) which stores the system option settings. System option settings are
retained if shelf power is lost or the H4TU-C-319 is unplugged.
USINGTHE MODE AND SEL PUSHBUTTONS
Setting Options through MODE and SEL
To provision the H4TU-C-319 through the MODE and SEL pushbuttons on the front panel:
1Press the MODE pushbutton for 1 second and then release it. The front-panel display alternately shows the
first system parameter and its current setting.
2Press the SEL pushbutton to step through all possible settings of the selected parameter. (See Table 5 on
page 19 and Table 6 on page 20.)
3After the desired setting has been sel ected, press the MODE pushbutton. This updates the current displayed
parameter to the selected setting, then advances to the next configurable parameter. After the last parameter
has been selected, a CONF NO message appears on the front-panel display.
4Do one of the following :
•To cancel the session without saving the requested parameter changes, press the MODE pushbutton or
do nothing. (After 30 seconds, the display returns to its normal mode without saving the new changes.)
•To accept the requested parameter changes, press the SEL pushbutton. (A CONFYES message appears,
and the display returns to its normal mode after saving the new changes.)

LTPH-UM-1031-03, Issue 3Provisioning
Resetting to Factory Default
All user options for the H4TU-C-319 List 1 (Table 5 on page 19) can be set to the factory default values using the
MODE and SEL pushbuttons. To set the user options to their default values:
1Press the SEL pushbutton for 6 seconds until the following message appears:
DFLT NO
2Press the SEL pushbutton while the DFLT NO message is displayed.
The message changes to DFLT YES indicating the factory default values are now in effect and the display
returns to the normal mode.
To terminate the DFLT mode without setting the factory default values, do one of the following:
•Press the MODE pushbutton to return to the normal display mode.
•Wait 30 seconds for the unit to return to the normal display mode.
Displaying System Parameter Settings
To scroll through the current settings of all system parameters, press the MODE pushbutton for 3 or more seconds.
The H4TU-C-319 displays the following parameters:
•Software version number
•List number
•Type of frame pattern received from the DSX-1
•Line code of the signal received from the DSX-1
•All user-configured parameter settings
•Loop attenuation threshold setting
•Margin alarm threshold setting
Disabling an Alarm
System alarms can be disabled by pressing the SEL pushbutton on the H4TU-C-319 front panel for less than 3
seconds. This executes an ACO and returns the H4TU-C-319 to its non-alarm state. For more information about
alarms, see “System Alarms” on page 42.
Loopback Modes
See “Loopback Operation” on page 46 for instructions on using the MODE and SEL pushbuttons to activate
loopbacks.
