Before you use a Data Metro II radio on the WAN, P-Com
recommends that you set up a basic radio configuration to make
sure the full WAN installation will proceed smoothly.
The basic configuration requires
• RF channel—all units in the WAN must use the same RF
channel. Separate WANs in the same geographic area may
need to use different channels. The DataMetro II Model 1280
provides nine channels; the Model 320 provides 14 channels.
• PN code—all units in the WAN must use the same PN code.
Different PN code sequences reduce interchannel and co-
channel interference between networks. The DataMetro II
provides eight PN codes.
• topology—the Data Metro II provides these topologies: peer-
to-peer, point-to-point, centralized (star base and star remote)
• reboot—to install the basic configuration
You can set up a basic radio configuration through one of three
methods:
• through twelve DIP switch positions
• through a terminal command line interface
• through the Site Manager software application
