1.1 HTU Applications

Figure 1-3 illustrates a drop/insert application where only a portion of the PCM

channel bandwidth is transported over one or more HDSL wire pairs. The

RS8953B provides drop/insert indicator signals to control external data MUXes

and internal routing tables to map timeslots from either one of two synchronized

PCM data sources. For remote terminals using partial payloads, the PCM channel

may be configured to operate either at the standard interface rate or at the Nx64

effective payload rate.
