LTPH-UM-1253-01 Overview
H4TU-C-231 List 5A October 15, 2003 1
OVERVIEW
The H4TU-C-231 List 5A (H4TU-C) line unit is the Central Office (CO) side of a T1 transmission system. The
four-wire HDSL4 product family 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 a maximum distance of
12 kft. over two unconditioned copper pairs. The H4TU-C supports three powered spans to further expand reach.
The H4TU-Cisdesigned to mount in standard 220 mechanics shelves. For a list of compatible shelves, see
“Compatibility” on page 58.

—Loop reversal detection on HDSL4 loop
—Spectrum compatibility with Asymmetric Digital Subscriber Line (ADSL) services
—Doubler (H4D) support for up to three spans
—Sources sealing current when connected to any locally powered H4TU-R
•Front-panel features

—Report menu option for downloading status and performance monitoring data to a file
—Remote provisioning through TL1 FDL
This line unit requires HiGain Management Unit (HMU) firmware version 3.2 or later (L9 or L7A)
for full feature TL1 management.

Overview LTPH-UM-1253-01
2 October 15, 2003 H4TU-C-231 List 5A

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 pairs at 784 kbps 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,
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.
DS1 is used throughout this document to refer to either the remote unit’s DS1 interface or the
line unit’s DSX-1 interface.

INSTALLATION
Figure 2. Installing an H4TU-C into a Shelf
1Align the H4TU-C with the enclosure slot guides, then pushthe unitin until it touches the backplane
card-edge connector.
2Place your thumbs on the H4TU-C front panel and push the H4TU-C firmly into the slot guides until the unit
clicks into the backplane and is properly seated.
Upon receipt of the equipment, inspect the contents for signs of damage. If the equipment has
been damaged in transit, immediately report the extent of damage to the transportation
company and to ADC.
When installing an H4TU-C in a chassis, be sure to wear an antistatic wrist strap. Avoid touching
components on the circuit board.
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 H4TU-C DSX-1 output ports to the
cross-connect panel must be grounded at both ends.

H4TU-C-231 List 5A October 15, 2003 7
VERIFICATION
Once the H4TU-C is installed, verify that it is operating properly. To do this, monitor the front-panel status LEDs.
1Verify that as the H4TU-C powers up, it attempts to communicate with a remote unit as the DSL LED flashes
red once every second. (Table 2 on page 5 lists the status messages.)
•If the H4TU-C is unable to communicate with the H4TU-R, the DSL LED displays solid red, indicating
HBER, MARG, or PWRF alarms.
•If the H4TU-C is able to communicate with the H4TU-R, the DSL LED displays solid green, indicating
that the HDSL4 spans are synchronized without error.
2Verify the presence of a DS1 signal by confirming that the ALM LED is off (not lit). If the ALM LED
displays red or yellow, a DS1 LOS condition exists. Refer to Table 2 on page 5 to locate the problem.
3Verify 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 on page 5 to locate the problem if these LEDs are
either flashing or display solid red.

Provisioning LTPH-UM-1253-01

PROVISIONING
ACCESSING THE PROVISIONING SCREENS
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 status, history, inventory, and provisioning screens
(see Figure 3 on page 9).
Connecting to a Maintenance Terminal
The craft port on the front panel allows you to connect the H4TU-C to a maintenance terminal, such as an ASCII
terminal or PC running a terminal emulation program. Once connected to a maintenance terminal, you can access
the maintenance, provisioning, and performance screens.
To connect to a maintenance terminal:
1Connect a standard 9-pin terminal cable to the RS-232 craft port on the H4TU-C front panel (Figure 1 on
page 3).
2Connect the other end of the cable to the serial port on the maintenance terminal.
3Start a terminal emulation program such as Procomm (emulating a VT100 terminal).
4Configure the maintenance terminal for the following communication settings:
•9600 baud
•No parity
•8 data bits
•1 stop bit
•Hardware flow control set to OFF
5If necessary, press + to refresh the HDSL4 logon screen.
Logon Screen
The maintenance terminal screens allow you to monitor, provision, and troubleshoot an HDSL4 system.
To select a menu from the logon screen (Figure 3 on page 9), do one of the following:
•Press the underlined letter of the menu.
•Use to select the menu, then press .
Table 3 on page 9 summarizes the navigational keys. They are also listed in the onscreen Help menu. Table 4 on
page 10 describes the logon screen menus.
No dip switches or jumpers are required to provision the H4TU-C 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 is unplugged.
