5.3 DS3 Framer Only Block Diagram
Figure 5 shows the TEMAP configured as a DS3 framer. In this mode the
TEMAP provides access to the full DS3 unchannelized payload. The payload
access (right side of diagram) has two clock and data interfacing modes, one
utilizing a gapped clock to mask out the DS3 overhead bits and the second
utilizing an ungapped clock with overhead indications on a separate overhead
signal. The SBI bus can also be used to provide access to the unchannelized
DS3.
