HE
The H2TU-C-319 List 7G 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-319 List 7G is designed to mount in 3192 mechanics
shelves.
