! SDA-4S models: integrated LAN switches, providing four 10/100BaseT
ports for interfacing with the subscriber’s PCs/network) These models
include the following:
− SDA-4S (standard): Standard integrated LAN switch, providing four
10/100BaseT interfaces to the subscriber’s computers.
− SDA-4S/VL: Provides VLANs between its ports and the SPR, ensuring
privacy between users of different ports (i.e., multi-tenant VLAN
security). For example, all users connected to Port 1 do not “see” users
connected to Port 2.
− SDA-4S/1H3L: Provides a high priority port (left-most port) for VoIP
traffic.
− SDA-4S/VL/1H3L: Combines the functionality of the SDA-4S/VL and
SDA-4S/1H3L models (VLAN for each port and a high priority port for
VoIP).
! Indoor Radio Adapter (IDR)—optional unit:
The IDR functions as a transceiver and a hub, eliminating the need for an SPR
and SDA. The IDR is installed inside the subscriber's premises, typically
mounted on a wall, desktop, or pole. The IDR is connected to a third-party
antenna, which is typically mounted outside to provide line-of-site with the base
station.
! Residential Gateway (RGW)—optional unit:
The RGW is a third-party unit that provides gateway support for VoIP. The
RGW is typically connected to the SDA through a 10BaseT port.
