The H2TU-C-231 List 7F line unit is the Central Office (CO) side of a T1 transmission
system. The H2TU-C, when used with an H2TU-R remote unit, transmits a 1.544 Mbps
payload on one unconditioned copper pair over the full Carrier Service Area (CSA) range.
The H2TU-C-231 List 7F is designed to mount in 220 mechanics shelves.
