LTPH-UM-1208-01 Overview
H2TU-C-202 List 7G June 6, 2003 1
OVERVIEW
The H2TU-C-202 List 7G (H2TU-C) line unit is the Central Office (CO) side of a T1 transmission system. The
HiGain HDSL2 product family is fully compliant with the HDSL2 standard ANSI T1.418.
The H2TU-C, when used with an H2TU-R remote unit, transmits a 1.552 Mbps payload on one unconditioned
copper pair over the full Carrier Service Area (CSA) range. The CSA includes loops up to 12,000 feet of 24 AWG
wire or 9,000 feet of 26 AWG wire, including bridged taps.
The H2TU-C is designed to mount in standard 200 and 400 mechanics shelves. For a list of compatible shelves,
see “Appendix C - Compatibility” on page 54.

APPLICATIONS
HiGain HDSL2 systems provide a cost-effective, easy-to-deploy method for delivering T1 High Capacity Digital
Service (HCDS) over a single copper pair. HiGain HDSL2 systems support a multitude of network connections
and system models.
•The service is deployed over one unconditioned, non-loaded copper pair.
•Conventional inline DS1 repeaters are no longer required.
•Cable pair conditioning, pair separation and bridged tap removal are not required.
Each loop has no more than 35 dB of insertion loss (INSL) at 196 kHz, with driving and terminating impedances
of 135Ω. In general, HiGain HDSL2 systems:
•Operate effectively inthe same cable binder group with other HDSL2 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.

ON-BOARD DIP SWITCH S2
The H2TU-C circuit board has an 8-position DIP switch, S2 (see Figure 2 below). Options that are configurable
through the DIP switch cannot be configured through the maintenance terminal screens. Configuration
information for the switches is reported on the screens, but is “read only.”OFF is the default setting of all switches.
Table 2 describes the functions of DIP switch S2.

INSTALLATION
Figure 3. H2TU-C Installation
1Align the H2TU-C with the enclosure slot guides, then push the unit in until it touches the backplane
card-edge connector (see Figure 3).
2Place your thumbs on the H2TU-C front panel and push the H2TU-C firmly into the slot guides until the unit
clicks into the backplane and is properly seated.
When installing an H2TU-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 H2TU-C DSX-1 output ports to the
cross-connect panel must be grounded at both ends.

LTPH-UM-1208-01 Installation
H2TU-C-202 List 7G June 6, 2003 7
VERIFICATION
Once the H2TU-C is installed, verify that it is operating properly. To do this, monitor the front-panel status LEDs.
Table 3 below lists the LED status and their functions (the H2TU-C reports alarm types and loopback status on
its front panel).
1Verify that as the H2TU-Cpowers up, it attempts to communicate with a remote unit as 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, the DSL LED displays solid green, indicating
that the HDSL2 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 3 to locate the problem.
3Verify error free DS1 transmission by confirming thatthe DS1, framing (ESF/SF), and line code (B8ZS/AMI)
LEDs display solid colors. Refer to Table 3 to locate the problem if these LEDs are either flashing or display
solid red.

Provisioning LTPH-UM-1208-01
8 June 6, 2003 H2TU-C-202 List 7G
PROVISIONING
ACCESSING THE PROVISIONING SCREENS
Use a maintenance terminal (ASCII terminal or a PC running terminal emulation software) connected to the
H2TU-C craft port (or to an HMU craft port) to access the status, history, inventory, and provisioning screens
(see Figure 4 on page 9).
Connecting to a Maintenance Terminal
The craft port on the front panel allows you to connect the H2TU-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 H2TU-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 HDSL2 logon screen.
Logon Screen
The maintenance terminal screens allow you to monitor, provision, and troubleshoot an HDSL2 system.
To select a menu from the logon screen (Figure 4 on page 9), do one of the following:
•Press the underlined letter of the menu.
•Use the arrow keys to select the menu, then press .
Table 4 on page 9 summarizes the navigational keys. They are also listed in the onscreen Help menu. Table 5 on
page 10 describes the logon screen menus.
Certain options are configured only by a DIP switch on the H2TU-C (see “On-board DIP Switch
S2” on page 5). Other options are configured using the maintenance terminal Config menus
(see “Making Changes to Standard and ADC Options” on page 13).
