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.

H4TU-R-402 LIST 1
The H4TU-R-402 List 1 remote unit (H4TU-R) functions as the remote end of a T1
transmission system. The H4TU-R, when used in conjunction with an HDSL4 line
unit (H4TU-C), transmits a 1.544 Mbps T1 payload a maximum distance of 12 kft
over two unconditioned copper pairs (26 AWG). Using two HD4-409 List 1 doublers
(H4Ds), the Carrier Service Area (CSA) reach can be extended to 34 kft. (see
“Specifications”).

REMOTE UNIT
QUICK INSTALLATION
VERIFICATION
After the H4TU-R is installed, verify that it is operating properly by monitoring the status
LEDs on the front panel.
REACH
The maximum reach of the H4TU-R-402 is based on a maximum signal loss over span 1 of
47 dB@196 kHz and a a maximum signal loss over spans 2 and 3 of 43 dB@196 kHz. The
following table lists the reach as a function of cable gauge.
LOGGING ON TO THE MAIN MENU
The H4TU-R-402 supports local and remote logon through a maintenance terminal (VT100
or a PC running VT100 terminal-emulation software). In HDSL4 systems equipped with the
H4TU-C, the maintenance terminal connects to the H4TU-C front panel craft port. In
HDSL4 systems equipped with the H4LXC, the maintenance terminal connects to the front
panel craft port of the Shelf Control Unit (SCU) controlling the H4LXC.
Remote login creates menus and screens for the H4TU-R that are identical to those viewed
at the H4TU-C or H4LXC. Once logged on, you can view system settings and inventory,
initiate loopbacks, monitor performance, and provision the circuit.
To log on and access the H4TU-C Remote Terminal Main Menu screens:
1Press the several times to display the Remote Login screen.
2Press the key to view the Maintenance Terminal Screen.The Remote Terminal
Main Menu items are replications of the line unit screens. Depending on the line unit
attached to the H4TU-R-402, remote provisioning may be available.
To log on and access the H4LXC Main Menu screens:
1Press the key twice to display the Logon screen.
2Type the assigned logon ID in the Enter Username field. If a logon ID is not assigned,
type SONEPLEX (default), then press .
3Type the assigned password at the Enter Password field. If a password is not assigned,
type SONEPLEX1.
4Press the key to view the Main Menu screen.
LOOPBACK TESTING
Initiate loopback testing from the maintenance terminal menus or by using in-band codes.
The inband codes shown below can be sent by a test set. For more information, refer to the
applicable H4TU-C or H4LXC line unit user manual.

VERIFICATION
After the H4TU-R is installed, verify that it is operating properly by monitoring the status
LEDs on the front panel.
REACH
The maximum reach of the H4TU-R-402 is based on a maximum signal loss over span 1 of
47 dB@196 kHz and a a maximum signal loss over spans 2 and 3 of 43 dB@196 kHz. The
following table lists the reach as a function of cable gauge.
LOGGING ON TO THE MAIN MENU
The H4TU-R-402 supports local and remote logon through a maintenance terminal (VT100
or a PC running VT100 terminal-emulation software). In HDSL4 systems equipped with the
H4TU-C, the maintenance terminal connects to the H4TU-C front panel craft port. In
HDSL4 systems equipped with the H4LXC, the maintenance terminal connects to the front
panel craft port of the Shelf Control Unit (SCU) controlling the H4LXC.
Remote login creates menus and screens for the H4TU-R that are identical to those viewed
at the H4TU-C or H4LXC. Once logged on, you can view system settings and inventory,
initiate loopbacks, monitor performance, and provision the circuit.
To log on and access the H4TU-C Remote Terminal Main Menu screens:
1Press the several times to display the Remote Login screen.
2Press the key to view the Maintenance Terminal Screen.The Remote Terminal
Main Menu items are replications of the line unit screens. Depending on the line unit
attached to the H4TU-R-402, remote provisioning may be available.
To log on and access the H4LXC Main Menu screens:
1Press the key twice to display the Logon screen.
2Type the assigned logon ID in the Enter Username field. If a logon ID is not assigned,
type SONEPLEX (default), then press .
3Type the assigned password at the Enter Password field. If a password is not assigned,
type SONEPLEX1.
4Press the key to view the Main Menu screen.
LOOPBACK TESTING
Initiate loopback testing from the maintenance terminal menus or by using in-band codes.
The inband codes shown below can be sent by a test set. For more information, refer to the
applicable H4TU-C or H4LXC line unit user manual.

H4TU-R-402 LIST 1
The H4TU-R-402 List 1 remote unit (H4TU-R) functions as the remote end of a T1
transmission system. The H4TU-R, when used in conjunction with an HDSL4 line
unit (H4TU-C), transmits a 1.544 Mbps T1 payload a maximum distance of 12 kft
over two unconditioned copper pairs (26 AWG). Using two HD4-409 List 1 doublers
(H4Ds), the Carrier Service Area (CSA) reach can be extended to 34 kft. (see
“Specifications”).

Enable Enables the flow of simplex sealing current from the upstream unit.
LPWR
Line power (default) Configures the H4TU-R-402 to receive power from the upstream line unit
over the HDSL pairs.
Local power Configures the H4TU-R-402 to receive power from a local -48 Vdc supply. If
local power is not present, the HRU reverts to line power mode.
