Figure 4-4 shows a “Star Network” Point-to-Multipoint Configuration where the Hub CDM-IP modem is
transmitting a common TDM carrier to three remote sites with CDM-IP modems. In turn, the Remote
CDM-IP is transmitting a link back to the Hub that is received by the CDD-564 (70/140 MHz) or CDD-
564L (L-Band) Satellite Quad Demodulator.

Since this is a Point-to-Multipoint configuration, HDLC addressing is used so that the traffic not intended
for a particular destination can be filtered (Small or Large HDLC Mode). For unicast traffic, it is best to
associate a unique HDLC address for each site in the network. In this case:
•
The Hub Site is HDLC 0x01
•
CDM-IP Remote ‘A’ is HDLC 0x02
•
CDM-IP Remote ‘B’ is 0x03
•
CDM-IP Remote ‘C’ is 0x04.
•
Each CDM-IP modem would select the HDLC address associated with its site as an Rx HDLC
Address. Therefore:
o
Both the Hub CDM-IP modem and CDD-564L would have 0x01 as the first RX HDLC
Address
