RS8953B/RS8953SPB
HDSL Channel Unit
1.1.2 Fractional Transport

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.
