SDA-4S:
integrated LAN switch, providing four 10/100BaseT interfaces with
the subscriber's PCs/network. The ports of the SDA-4S models support
Auto
Negotiation
, allowing automatic configuration for the highest possible speed
link: 10BaseT or 100BaseT, and Full Duplex or Half Duplex mode. In other
words, the speed of the connected device (e.g. a PC) determines the speed at
which packets are transmitted through the SDA-4S port. For example, if the
device to which the port is connected is running at 100 Mbps, the port
connection will transmit packets at 100 Mbps. If the device to which the port is
connected is running at 10 Mbps, the port connection will transmit packets at 10
Mbps.
The SDA-4S ports also support automatic
MDI/MDI-X
crossover detection,
allowing connection of straight-through or crossover CAT 5 cables to any port.
The SDA-4S is available in the following models:
SDA-4S (standard):
standard integrated LAN switch, providing four
10/100BaseT interfaces with the subscriber's computers. This model is ideal
for SOHO implementation.
SDA-4S/DC:
integrated LAN switch, providing four 10/100BaseT interfaces
and especially designed for implementation where available power supply is
DC (10 to 52 VDC), e.g. from a
solar panel
or car lighter, which typically
provide 12 VDC. This model provides regulated –48 VDC power to the SPR.
SDA-4S/VL:
provides VLANs between ports and the SPR, ensuring privacy
between LAN users of the different ports. For example, all users connected
to Port 1 do not "see" users connected to Port 2. This model is ideal for
multi-tenant (VLAN security) implementation.
SDA-4S/VLtag:
ideal for multi-tenant applications where traffic engineering
and privacy is required. SDA-4S/VLtag assigns a specific VLAN ID to
traffic, based on the SDA-4S/Vltag port at which the traffic arrives. 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 through ASWipLL's network management system (WipManage).
The tag conversion is performed by SPR before sending the traffic to the air
(i.e. to the BSR) and vice versa when coming from the air.
