Understanding the network
Figure 1 shows a typical deployment of the IP Radio Node 8000 (IP-RN 8000).
• The IP-RN 8000 is installed at the base of a cell tower and achieves two-way radio communications
with access terminals through RF antennas as appropriate.
• The IP-RN 8000 receives timing signals through primary and optional redundant Global Positioning
System (GPS) antennas.
• The IP-RN 8000 is grounded and connected to a power source.
• Each IP-RN 8000 is connected through backhaul links (up to four T1/E1s or a primary and optional
redundant 10/100 Mbit/sec Ethernet) to an IP Radio Network Controller 8500 (IP-RNC 8500).
These backhaul links carry access terminal data communications and IP-RN 8000 management
communications.
• The IP-RNC 8500 is connected to the Internet through a packet data serving node (PDSN). This link
carries all data communications between the access terminals and the Internet.
For more information on IP-RN 8000 backhaul, antenna, power, ground and other connections, see
Understanding external connections
on page 34.

NOTE
Figure 1 shows the network connections and devices in a typical
IP-RN 8000 deployment. As with all networks, there are many
variations of deployment and connectivity options. For more
