Customer Table (EUM only)
The purpose of the Customer Table is to give the system operator control over the number of
PCs that can access the Internet through the EUM. The Customer Table is optimized for the
case where multiple hosts are connected to the EUM, but only one accesses the Internet at
any given time. The Customer Table also acts as a bridging table, ensuring local traffic is kept
local.
The Customer Table presents a list of the end-user computers that are connected to the EUM.
If customer_max is set to “1”, only one of the computers in the table will have air access. If
customer_max is set to “n”, up to “n” computers in the Customer Table will have air access.
Air access is assigned on a “first come, first served” basis. If n=1, the first computer to transmit
packets will be granted air access. All other computers will be denied air access. If the
computer that has been granted air access, does not transmit traffic for 10 minutes, then his
air access will be removed and the next computer that transmits a packet will be granted air
access.
More generally, for any “n”, up to customer_max, the first n computers transmitting packets will
be granted air access and, if any of them fails to transmit traffic for 10 minutes, their air access
will be removed, allowing the next computer without air access to be granted air access as
soon as they transmit data.
The contents of the Customer Table are:

NOTE: If customer max is set to 1, and you want to connect a different
PC to the EUM, for maintenance purposes, for example, you
must clear the Customer Table, reset the EUM, or wait for 10
minutes.
