For internal use only HiPath 3000 System Overview
HiPath 3800
– PCM segment for the board slots 7 – 10 = 128 time-division multiplex channels (4 PCM
highways)
DIUN2, DIU2U (U.S. only) and STMI2 use the PCM highways of trunk group F. As a result,
an additional 128 time-division multiplex channels for slots 1 – 5 and slots 7 – 10 are provided
for these boards.
If the installation of these boards necessitates a greater number of time-division multiplex
channels than the 2 x 128 available with trunk group F, the system automatically uses the
time-division multiplex channels available with trunk group A. However, only complete
boards are switched to the other trunk group. The remaining time-division multiplex channels
are not used.
● Two-cabinet system (basic cabinet + expansion cabinet)
All peripheral boards use only the PCM highways of trunk group A.
Expansion cabinet: PCM highways

Figure 2-5 HiPath 3800 - Expansion Cabinet PCM Highways
The expansion cabinet provides a PCM highway trunk group with 2 x 4 PCM highways. There
are approximately 32 time-division multiplex channels available for each PCM highway.
● PCM segment for the board slots 1 – 6 = 128 time-division multiplex channels (4 PCM highways)
● PCM segment for the board slots 8 – 14 = 128 time-division multiplex channels (4 PCM
highways)
Trunk group F’s PCM highway is not used.
