power is limited to 100 mW/MHz giving typical indoor coverage of 20
to 50 metres.
2.2.12 Wired Encryption Privacy (WEP)
MW1122 supports full-speed WEP encryption and both
authentication methods defined in IEEE 802.11b: Open-key and
shared-key authentication. The encryption is 40-bit RC4 WEP
encryption. Additionally, MW1122 supports 128-bit RC4 WEP
encryption.
2.2.13 Weighted Fair Queueing (Class of Service)
As a Class of Service (CoS) function, MW1122 supports Weighted
Fair Queueing (WFQ) for each ATM VCC. The CoS function ensures
that different IP traffic flows are treated fairly in the upstream (towards
the Internet) direction. This may be necessary, in some cases, because
the upstream capacity of the ADSL line is somewhat limited compared
to the Ethernet bandwidth on the office or home LAN. The WFQ CoS
function classifies IP traffic flows based on IP address, protocol and
port fields. It is capable of identifying the IP flow from all supported
payload encapsulation formats. WFQ works properly only with
IP-based protocols. If the flow is IP-based but is encrypted using IPSec
or PPP encryption, then WFQ cannot identify the flows correctly. In
this case, the default flow is used and the default flow is treated as a
single flow.
2.2.14 Management
There are three management methods in MW1122:
D Command line interface (CLI) through console serial port
D CLI via telnet
D Web browser management
The CLI allows complete configuration of the unit; the Web browser
management allows the configuration of the most frequently used
configuration parameters.
2.2.15 Dedicated management channel
The operator or the Internet Service Provider can establish a dedicated
management channel to MW1122. This channel provides access to the
