Functional Operation

The HiGain system uses ADC 2-Bit 1-Quartenary (2B1Q) HDSL transceiver systems to establish two full-
duplex 784 kbps data channels between the HLU-200 List 1D and a HRU-412 HiGain Remote Unit. This
provides a total capacity of 1.568 Mbps between the two units.
A block diagram of the HLU-200 List 1D is shown in Figure 3. The Litespan gate array circuit controls the
exchange of the 1.544 Mbps data payload between the backplane and the 2180 T1 framer. The 2180 processes
the T1 data and reorganizes Super Frame (SF) or Extended Super Frame (ESF) format. It also performs
HLU-200 List 1D
