! 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/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).
Figure 9-1 displays a typical setup of the SPR and SDA at the subscriber's premises.
Note: The SDA can also be installed at a base station that has only one BSR.
This SDA replaces the need for the BSDU, and provides power and
connectivity to the single BSR.
