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 requiredbecause 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 remainfree.● Two-cabinet system (basic cabinet + expansion cabinet)All peripheral boards use the PCM highways from trunk group A only.Expansion cabinet: PCM highwaysThe expansion cabinet provides a PCM highway bundle with 2 x 4 PCM highways. There are32 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.Figure 4-27 HiPath 3800 - PCM Highways in the Expansion CabinetBundle A’s PCM highwaywith 2 x 4 PCM highwaysConnection to the PCM highwaytrunk group F in the basic cabinetPCM highway trunk group F(not used)HDLC connection to the basic cabinetHDLC
