Overview
As part of Aperto Networks' PacketWave Broadband Multiservice Wireless Access System,
PacketWave 200 Series Subscriber Units delivers high-speed, always-on Internet access to
small and medium-sized businesses, small offices/home offices (SOHO), and residences.
Models and Functionality
There are three models in the PacketWave 200 Series:
• The PacketWave 210 operates in bridging mode, supporting up to 5 hosts and 4 ser-
vice flows. It is ideal for residential subscribers.
• The PacketWave 220 operates in bridging and NAT modes, supporting up to 20 hosts
and 4 service flows. It is ideal for small office/home office (SOHO) subscribers.
• The PacketWave 230 operates in bridging, NAT, and IP routing modes, supporting
up to 254 hosts and 16 service flows. It is ideal for small and medium enterprises.
Figure 2-1 graphically illustrates the applications of the three PacketWave 200 models.
VLAN and PPPoE/PPP
All PacketWave 200 models support VLAN mode, essentially a variation of bridging mode.
In bridging mode, VLAN-tagged frames are transmitted and received transparently ( VLAN
pass-through). In VLAN mode, the PacketWave 200 functions as a bridge, but with the
ability to tag untagged frames from the Ethernet port with VLAN ID and user priority and
to strip tags from VLAN-tagged frames received at the wireless interface.
In NAT mode, the PacketWave 220 and 230 can be configured to support PPP over Ethernet
(PPPoE). These PacketWave models include a built-in PPPoE client, eliminating the need
for each host to have a PPPoE client and to originate connections by logging in.
For more about VLAN and PPPoE, see the PacketWave 1000 Base Station Unit Manual.
