− SDA-4S/VLtag: This model is ideal for multi-tenant applications where
traffic engineering and privacy is required. SDA-4S/VLtag assigns the
traffic from each of its four ports with a different VLAN ID. The VLAN
IDs are fixed (since SDA-4S/VLtag is not user configurable). SPR
converts the four VLAN IDs tagged by SDA-4S/VLtag to four VLAN
IDs configured via WipLL’s NMS. The tag conversion is performed by
SPR before sending the traffic to the air and the other way around when
coming from the air.
− 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):
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. Typically, the
RGW provides two POTS ports for telephony; a LAN port for the local
PC/network; and a LAN port for connectivity to the SDA.
