HiPath 3000 System Overview For internal use only
HiPath 3800
2.2.2 Distribution of PCM Segments
HiPath 3800 provides PCM highway trunk groups, each with 2 x 4 PCM highways for the peripheral
board slots. There are approximately 32 time-division multiplex channels available for
each PCM highway. Blockages occur when these channels are busy. This prevents the system
from performing any more call jobs.
To guarantee that the system operates without blocking, make sure when performing configuration
that the boards on a PCM segment do not require more than the number of time-division
multiplex channels available. The following figures show the PCM highways for both system
cabinets of the HiPath 3800.

Figure 2-4 HiPath 3800 - Basic Cabinet PCM Highways
The basic cabinet provides two PCM highway trunk groups, each with 2 x 4 PCM highways.
There are approximately 32 time-division multiplex channels available for each PCM highway.
The basic cabinet’s PCM highway trunk groups are used by peripheral boards according to the
following rules:
● Single-cabinet system (basic cabinet only)
With the exception of DIUN2, DIU2U (U.S. only) and STMI2 boards, peripheral boards only
use the PCM highways of trunk group A:
– PCM segment for the board slots 1 – 5 = 128 time-division multiplex channels (4 PCM
highways)
