3G CDMA NIM/Cellular Interface
3G CDMA NIM, Cellular Interfaces, and Your Network
The 3G CDMA NIM functions as a cellular interface and a cellular modem. The cellular interface is a
physical interface, designated as part of a demand routing resource pool. The demand interface draws on
the demand routing resource pool to connect with the public network, while the cellular interface connects
with physical interface on the public side of the network to complete the connection. The relationship of
the 3G CDMA NIM, the cellular interface, and the demand interface is shown in Figure 2.
