– PCM segment for board slots 7 – 10 = 128 time-division multiplex channels (four PCM
highways)
DIUT2, DIUN2, DIU2U (for U.S. only), and STMI2 use the PCM highways from trunk group
F. Thus there are an additional 128 time-division multiplex channels available for slots 1 –
5 and for slots 7 – 10 for these boards.
If more than the 2 x 128 time-division multiplex channels from trunk group F are required
because of the configuration with these boards, the system will automatically resort to time-
division multiplex channels from trunk group A. However, only complete boards are acti-
vated on the other trunk group. The remaining time-division multiplex channels remain
free.
● Two-cabinet system (basic cabinet + expansion cabinet)
All peripheral boards use the PCM highways from trunk group A only.
Expansion cabinet: PCM highways
The expansion cabinet provides a PCM highway bundle with 2 x 4 PCM highways. There are
32 time-division multiplex channels available for each PCM highway.
● PCM segment for board slots 1 – 6 = 128 time-division multiplex channels (four PCM high-
ways)
● PCM segment for board slots 8 – 14 = 128 time-division multiplex channels (four PCM high-
ways)
PCM highway bundle F is not used.
