This figure shows one EPIC connecting four PCM highways to one packet handler
internal highway. These highways are accessed by the IDECs, which are 4 channel
HDLC controller and handle the packets. If more than four PCM highways shall be
connected to the centralized packet handler, further EPICs are necessary. Such a
configuration is shown in figure 12, where 8 highways are switched to one packet
handler internal highway. In this case the two EPICs are connected in parallel at the
packet handlers internal side.

Centralized Packet Handler with One Internal Highway Connected to 8 PCM High-
ways
The data rate of the packet handler internal highway can be up to 4.096 Mbit/s. If this
capacity is not sufficient, other packet handler internal highways may be added as
depicted in figure 13.
