The HiGain H2TU-R-402 List 1B and List 1C remote units are the customer premises
side of a repeaterless T1 transmission system. The system provides 1.544 Mbps
transmission of a T1 payload on one unconditioned pair over the full Carrier Service
Area (CSA) range. The CSA includes loops up to 12,000 feet using 24 AWG wire or
up to 9,000 feet using 26 AWG wire.
Enhanced firmware allows the H2TU-R-402 List 1B and List 1C to be deployed in the
Wideband 3190 protection switching applications. These applications have the
following system requirements: two HXU-358 Multiplexers (software version 1.04 or
higher), an HMU-319 List 7A or List 7C Management Unit (software version 3.06 or
higher), an H2TU-C-319 List 2 Line Unit, and an HRE-206 Remote Enclosure
equipped with a PSC-606 Protection Switching Controller.
