Appendix B - Functional Operation

A
PPENDIX
ADC HDSL2 technology provides full-duplex services at standard DS1 rates over copper wires between an
H2TU-C and an H2TU-R, which comprise one HiGain HDSL2 system. HiGain HDSL2 systems use ADC
Overlapped Pulse Amplitude Modulation (PAM) Transmission with Interlocking Spectra (OPTIS) transceiver
systems to establish full-duplex, 1.552 kbps data channels between the H2TU-C-231 and a remotely located
H2TU-R.
A block diagram of the H2TU-C-231 is shown in
stream from the DSX-1 digital cross connect interface. The H2TU-C contains a DS1 frame synchronizer
controlled by an 8-bit microprocessor that determines the type of framing on the DS1 stream and synchronizes to
it. The H2TU-C recognizes Superframe (SF) or Extended Superframe (ESF) framing. When the data is unframed,
the H2TU-C arbitrarily defines a frame bit.
