HIGH DENSITY VT/TU MAPPER
AND M13 MULTIPLEXER
5.2 VT/TU Mapper Only Mode Block Diagram
Figure 4 shows the TEMAP configured as a VT or TU mapper. In this mode the
TEMAP provides access for up to 28 independent unframed 1.544Mb/s streams
or 21 independent unframed 2.048Mb/s streams. The 1.544Mb/s and 2.048Mb/s
streams can be accessed on the system side as clock and data as shown in
Figure 4, or they can be accessed via the SBI bus. The T1 or E1 framers and
performance monitoring blocks can be used to monitor the passing traffic in
either the ingress or egress direction. The M13 Multiplexer mode operates in
much the same way as the VT and TU mapper shown in Figure 4.
