Figure 13
Centralized Packet Handler with 3 Internal Highways
In some applications an additional collision resolution signal is required for the HDLC
controllers. This information can be demultiplexed from the PCM highways to a third line
for each packet handler internal highway (refer to figure 14).

The applications apply equally to centralized signaling as well as to data packet
handlers.
