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 pro-
vided 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 activated on the other trunk group. The remaining time-division multiplex chan-
nels remain free.
Two-cabinet system (basic cabinet + expansion cabinet)
All peripheral boards use only the PCM highways of trunk group A.
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 high-
ways)
PCM segment for the board slots 8 – 14 = 128 time-division multiplex channels (4 PCM
highways)
