OVERVIEW

The H4TU-C-319 List 1 is the Central Office (CO) side of a T1 transmission system. The ADC® four-wire HDSL2 product family (hereafter referred to as “HDSL4”) is based on the HDSL4 standard ANSI T1.418 Issue 2.

The H4TU-C, when used with an H4TU-R remote unit, transmits a 1.544 Mbps payload up to a maximum distance of 12 kft. over two unconditioned copper pairs. Using two doublers (H4Ds), the Carrier Service Area (CSA) reach can be extended to a maximum of 34 kft. The H4TU-C-319 List 1 is designed to mount in 3192 mechanics shelves. For a list of compatible shelves see “Appendix C - Compatibility” on page 65.

The H4TU-C-319 List 1 complies with the protection switching features of the PSC-606 List 1 protection switching card. See the PSC-606 List 1 technical practice, document number LTPH-TP-1006-xx for detailed information.
