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.

LPS-H4TU-C-L5
The LPS-H4TU-C-L5 (LPS-H4TU-C) line unit is the Central Office (CO) side of a T1
transmission system. The LPS-H4TU-C, when used with an H4TU-R-402-5A remote
unit, transmits a 1.544 Mbps payload a maximum distance of 12 kft. (26 AWG) over
two unconditioned copper pairs. The Carrier Service Area (CSA) range can be
extended to a maximum of 34 kft.(26 AWG). (See Compatibility inside.) The
LPS-H4TU-C-L5 inter-operates with HiGain HDSL4 repeaters and remotes.

INSTALLATION
1Align the LPS-H4TU-C with the chassis slot guides (Loop Extender chassis,
Broadband chassis, or LoopStar) and slide the unit in until it touches the
backplane connector.
2Raise the extraction lever at the bottom of the front panel to press the
LPS-H4TU-C into the backplane connector.
POWER-UPSEQUENCE
When the HDSL4 powers up, the following occurs:
1The STAT LED briefly light red, then yellow, indicating that the power is on and
that the self-test diagnostics are beginning. The remaining LEDs momentarily
light yellow, then turn off.
2The front-panel LEDs light as follows upon successful completion of the self-test
diagnostics:
•STAT - Green
•RMT ALM - Off (or yellow when the HDSL4 LOSW/BER LED is red)
•LPBK - Off
•DS1 LOS/BER - Off (or red, if DS1 is absent)
•B8ZS - Off when set to AMI; green when set to B8ZS
•HDSL4 Loop 1 and Loop 2 - Momentarily solid Red, then flashing green
during loop activation, then solid green
3Ifall LED indicatorsrespondas described, pressthe LMPTSTswitch on the APU
to verify that all LEDs on the front panel of the line unit light yellow. This

VERIFICATION
Once the LPS-H4TU-C-L5 is installed, verify that it is operating properly by monitoring
the Status LEDs on the front panel.
LOGGING ONTO THE MAIN MENU
The LPS-H4TU-C-L5 supports system logon through a maintenance terminal (VT100 or a
PC running VT100 terminal-emulation software) connected to the Craft port on the SCU
front panel. Once logged on, you can access the Main Menu screens to view local and
remote system settings, provision the circuits,perform maintenance, and viewperformance
screens.
To log on and access the Main Menu screens using a maintenance terminal:
1Press the key twice to display the Logon screen.
2Typethe assignedlogon ID in theEnterUsernamefield. If a logon ID is not assigned,
type LOOPSTAR or SONEPLEX (depending on type of system chassis), then press
.
3Type the assigned password at the Enter Password field. If a password is not
assigned, type LOOPSTAR1 or SONEPLEX1.
4Press the key to view the Main Menu screen.
LOOPBACK TESTING
Initiate loopback testing from the maintenance terminal menus or by using inband codes.
The inband codes shown below can be sent by a test set. For more detailed information,
refer to the LPS-H4TU-C-L5 User Manual (LTPS-UM-8054-01).
Pressing the CO loopback button for more than 5 seconds will initiate a simultaneous
network and customer loopback at the H4TU-R.
COMPATIBILITY
The LPS-H4TU-C is compatible with the H4TU-R-402-5A remote unit and H4D-409-L2
doublers. The table shows the various transmission distances possible with and without
doublers. For more information about the remote unit, refer to LTPH-QI-1254-xx; for the
doubler unit, refer to LTPH-QI-1120-xx.

LOOPBACK TESTING
Initiate loopback testing from the maintenance terminal menus or by using inband codes.
The inband codes shown below can be sent by a test set. For more detailed information,
refer to the LPS-H4TU-C-L5 User Manual (LTPS-UM-8054-01).
Pressing the CO loopback button for more than 5 seconds will initiate a simultaneous
network and customer loopback at the H4TU-R.
COMPATIBILITY
The LPS-H4TU-C is compatible with the H4TU-R-402-5A remote unit and H4D-409-L2
doublers. The table shows the various transmission distances possible with and without
doublers. For more information about the remote unit, refer to LTPH-QI-1254-xx; for the
doubler unit, refer to LTPH-QI-1120-xx.

LPS-H4TU-C-L5
The LPS-H4TU-C-L5 (LPS-H4TU-C) line unit is the Central Office (CO) side of a T1
transmission system. The LPS-H4TU-C, when used with an H4TU-R-402-5A remote
unit, transmits a 1.544 Mbps payload a maximum distance of 12 kft. (26 AWG) over
two unconditioned copper pairs. The Carrier Service Area (CSA) range can be

INSTALLATION
1Align the LPS-H4TU-C with the chassis slot guides (Loop Extender chassis,
Broadband chassis, or LoopStar) and slide the unit in until it touches the
backplane connector.
2Raise the extraction lever at the bottom of the front panel to press the
LPS-H4TU-C into the backplane connector.
POWER-UPSEQUENCE
When the HDSL4 powers up, the following occurs:
1The STAT LED briefly light red, then yellow, indicating that the power is on and
that the self-test diagnostics are beginning. The remaining LEDs momentarily
light yellow, then turn off.
2The front-panel LEDs light as follows upon successful completion of the self-test
diagnostics:
•STAT - Green
•RMT ALM - Off (or yellow when the HDSL4 LOSW/BER LED is red)
•LPBK - Off
•DS1 LOS/BER - Off (or red, if DS1 is absent)
•B8ZS - Off when set to AMI; green when set to B8ZS
•HDSL4 Loop 1 and Loop 2 - Momentarily solid Red, then flashing green
during loop activation, then solid green
3Ifall LED indicators respond as described, pressthe LMPTSTswitch on the APU
to verify that all LEDs on the front panel of the line unit light yellow. This
indicates that the LEDs are functional. Continued
