HIGH DENSITY T1/E1 FRAMER
AND M13 MULTIPLEXER
5.2 M13 Multiplexer Mode Block Diagram
Figure 4 shows the TECT3, configured as a M13 multiplexer, connected to a
synchronous H-MVIP system side bus. In this example the TECT3 provides
synchronous access to the fully channelized T1s (access to all DS0s)
multiplexed into the DS3. There is also synchronous H-MVIP access to all
channel associated signaling channels (CAS). An additional H-MVIP interface
can be used to provide synchronous access to the common channel signaling
channels (CCS), although this same information is available within the data H-
MVIP signals.

5.3 DS3 Framer Only Block Diagram
Figure 5 shows the TECT3 configured as a DS3 framer. In this mode the TECT3
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.
