DESCRIPTION
WI-FI CO-BASED DSLAM DEPLOYMENT
Using existing DSLAMs, a G.SHDSL or ADSL pair is routed to the LPS-300C power card in the HMS-318 power
shelf (Figure 2). The LPS-300C is a 3192 double-wide card that supports two powered xDSL pairs per module. A
total of 11 LPS-300C cards can be installed in the UL-60950 compliant HMS-318 power shelf for a total of 22
span-powered pairs. The LPS-300C, without affecting the xDSL signal, adds power to the span to operate the
LPS-20x.
The access point converts the ATM data coming in on the span and bridges it an Ethernet transparent bridge
broadcasting via 802.11b Wi-Fi standards to any client who has a wireless Network Interface Card (NIC).
The Access Controller forwards to the RADIUS Server authentication requests, then the RADIUS Server
authenticates the user. Once authenticated, the user has access to the internet. The Access Server tracks the
connection time for billing purposes. Some applications may include the replacement of pay phones with LPS-20xs
to create a wireless public hotspot.
