VERVIEW
The LPS-H4TU-C-L5 Central Office (CO) module is a low-power, plug-in unit that installs in a Soneplex
Broadband Chassis or Soneplex Loop Extender Chassis at the central office. Hereinafter referred to as the
H4LXC, this CO module provides DS1/HDSL4 signal conversion, and status and alarm reporting. The module is
only compatible with the H4TU-R-402-5A remote module.
The LPS-H4TU-C, when used in conjunction with an H4TU-R-402-5A remote unit (H4LXR), provides 1.544
Mbps full-duplex T1 transmission on two unconditioned copper pairs over the full Carrier Service Area (CSA)
range. The CSA includes loops of up to 16,000 feet on 24 AWG wire or 12,000 feet on 26 AWG wire, including
bridged taps.
The H4LXC functions and features described in this manual are supported by Shelf Controller
Unit (SCU) Software Version 3.5 through 4.1.1. For information about this card when running
under SCU v5.0 and higher, refer to LTPS-UM-8068-xx.
