Revision History
Revisions to this practice will be summarized in this
paragraph.
The E220 HFAC provides a common access point to
performance and provisioning information related to
each HDSL / HDSL2 transceiver unit for the central
office (HTU-C and H2TU-C) deployed in the E220
shelf. By addressing the HTU-C or H2TU-C, the HFAC
also provides support for the HDSL / HDSL2 range
extender (HRE and H2R) and the HDSL / HDSL2
transceiver unit for the remote end (HTU-R and H2TU-R).
The shelf supports one shelf controller (HFAC) and up
to 13 HTU-C / H2TU-C cards for the 23-inch shelf or 11
HTU-C / H2TU-C cards for the 19-inch shelf. A
faceplate-mounted DB9 connector provides a VT 100
compatible terminal interface for controlling the
system.
