TMCAS in HiPath 3750 and HiPath 3700
A maximum of four TMCAS boards can be used in the HiPath 3750 and HiPath 3700. For power
supply reasons, a maximum of two TMCAS are possible for one cabinet. Because the board
does not need a PCM highway, there are no restrictions concerning the 64 time-division multi-
plex channels per PCM segment. However, TMCAS must always be plugged in to the left of the
associated TMS2. An example of a TMCAS in the HiPath 3750 and HiPath 3700 cabinet is
shown in Figure 3-118.
