The H2TU-C-319 List 1E (H2TU-C) line unit is the Central Office (CO) side of a T1
transmission system. When the H2TU-C is used in conjunction with a HiGain
High-bit-rate Digital Subscriber Line 2 (HDSL2) remote unit (H2TU-R), the system
provides 1.552 Mbps transmission 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 or 9,000 feet of 26 AWG wire, including bridged taps.
