5.2 DS3/E3 Framer Only Block Diagram
PROPRIETARY AND CONFIDENTIAL
Figure 5 shows the TEMAP-84 configured as a DS3 or E3 framer. In this mode
the TEMAP-84 provides access up to three full DS3/E3 unchannelized payloads.
The payload access (right side of diagram) has two clock and data interfacing
modes, one utilizing a gapped clock to mask out the DS3/E3 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/E3.
