Status The protocol status.
VC 1 Bridge Settings
Bridge = A bridge is a layer 2 device that connects two segments of the same LAN that use the
same protocol such as Ethernet. The modem does not have a WAN IP address in this mode. The
client PC will typically get an IP address form a DHCP server in the network or it can be assigned
statically.
Routed Bridge = Routed Bridged Encapsulation (RBE) is the process by which a bridged segment
is terminated on a routed interface. Specifically, VersaLink is routing on an IEEE 802.3 or
Ethernet header carried over RFC 1483 bridged ATM. RBE was developed to address the known
RFC1483 bridging issues, including broadcast storms and security. The modem will get a WAN
IP address through DHCP or can be assigned statically. NAT will use the global address assigned
to the modem.
Proxy Bridge = Proxy Bridge is the process in which the modem acts as a proxy ARP agent for a
local public subnet. The modem will be assigned an IP address from within that public subnet.
The modem will direct all traffic to a VersaLink, which is configured statically. VersaLink
address must not reside within VersaLink’s assigned public subnet. All traffic will be sent via
VersaLink’s MAC address. The LAN may also have a private NAT'ed network. NAT will use the
global address assigned to the modem.

Wireless Card Information
Network Name (SSID) This string, (32 characters or less) is the name associated with the Access
Point (AP). To connect to the AP, the SSID on a Station card must match the
SSID on the AP.
802.11 MAC Address (BSSID) This is the Media Access Controller address of the AP. It is used as the Basic
Service Set Identifier.
FW Version This is the Network Interface Card Identifier. It uniquely identifies the
hardware platform of the AP. This is used with other information to
determine if the inserted card can be used as an AP, and if so, the version of
AP firmware to be used. Not all makes of wireless station cards can be used
as an AP.
Communication Statistics
NOTE: Data preceded by OUT pertain to transmissions from the VersaLink to a station; VersaLink is the source.
Data preceded by IN pertain to data received by VersaLink; VersaLink is the destination.
OUT-Unicast Frames The number of successfully transmitted frames whose destination address
was a single station; not necessarily the same station, but to any single
station as opposed to a transmission that multiple stations would receive-as
in the case of broadcast message.
OUT-Multicast Frames The number of successfully transmitted frames whose destination address

broadcast to all stations, but more than a single station. Broadcast messages
are included in the count.
OUT-Fragments The number of successful transmissions made. This will typically be greater
than the sum of the Unicast and Multicast frames because large frames are
broken into multiple transmissions. The number of fragments per frame is
based on the Fragmentation Threshold setting (not user-configurable).
OUT-Frames after single retry The number of frames that were successfully transmitted after one, and only
one, retry. All fragments of the frame must have met this requirement if the
frame was fragmented.
OUT-Frames after many retries The number of frames that successfully transmitted after more than one
retry. Any fragment of a frame that required multiple retries would
increment this counter for the whole frame.
OUT-Dropped Frames, too many
retries
The number of frames that did not transmit due to the short or long retry
limit being reached because no acknowledgement or CTS was received.
OUT-Discarded Frames The number of transmit requests that were discarded to free up buffer space
on the NIC. This count is incremented when one of the following occurs:
1) A transmit request is queued too long on the transmit queue due to
excessive retries, deferrals, scans, etc.
2) A transmit request is queued too long on the Power-Save queue because
the station did not poll or wake up in time.
IN-Unicast Frames The number of successfully received frames whose destination address was a
single location, not necessarily the same location, but to any single location
as opposed to the broadcast address.
IN-Multicast Frames The number of successfully received frames whose destination address was a
multicast address. Broadcast messages are included in this count.
IN-Fragments The number of fragments successfully received. This may not be equal to the
sum of the Unicast and Multicast frames because large frames are broken
into multiple transmissions. The number of fragments per frame is based on
the Fragmentation Threshold setting (not user-configurable) on the source
station.
IN-Drops due to insufficient Rx
buffers
The number of received frames discarded due to lack of buffer space.
IN-Packet not passing checksum The number of received frames with a Frame Check Sequence (FCS) error.

Diagnostics Help
This screen provides tools for diagnosing PPP connection problems. Some tests depend on VersaLink’s status and
the capabilities exercised by previous tests, which may prevent other types of testing.
Beginning of Diagnostics Help screens
DSL
VersaLink status checks the connection. The following is a list of the possible responses:
DSL
Up VersaLink is operating correctly and has obtained synchronization with the
opposing modem.
Down Explanation: VersaLink is operating correctly, but has not synchronized with the
opposing DSLAM.
Solution: First, check to be sure that the cable connecting VersaLink to the
ADSL wall jack is properly connected at both ends. If the cable is properly
connected and VersaLink does not synchronize, try another phone cable. Next,
wait for VersaLink to train. It can sometimes take as long as two minutes for
VersaLink to train. If it still has not come into synchronization, power cycle
VersaLink. If you have tried the approach above and VersaLink still does not
synchronize, contact your service provider.
PPPoE
The PPPoE status indicates if a PPPoE session is established (i.e., if the PPPoE Discovery procedure has
completed). The following is a list of the possible responses:
PPPoE
Session up A valid PPPoE session has been detected.
no session Currently there is no active PPPoE session. A PPP session must be connected
from the homepage screen.
initiating session The connection process for a PPPoE session has been initialized. It can
sometimes take a few seconds for the PPPoE Discovery procedure to complete.
Wait 10-15 seconds and try again. If the PPPoE Discovery still cannot complete,
there may be a configuration issue with your service provider's equipment.
Verify your VPI/VCI settings (on the LAN Advanced page) and contact your
ISP provider.
Session halted A successful PPPoE session was halted. A PPP session must be connected from
the homepage screen.
passed A valid PPPoE session was established.
Session failure A PPPoE session could not be made. There may be a configuration issue with
your service provider's equipment. Verify your VPI/VCI settings (on the LAN
Advanced page) and contact your provider.

PPP
This field displays the PPP Connection status. A PPPoE or PPPoA session must already be established. The
following is a list of the possible responses:
PPP
Connection up VersaLink has established a PPP connection.
no connection There is no PPP connection. A PPP session must be connected from the
homepage screen.
initiating connection The PPP connection process has been initialized.
Connection halted A successful PPP connection was halted. Solution: A PPP session must be
connected from the homepage screen.
Cannot connect Explanation: A PPP connection could not be made because of a PPPoE session
failure.
Authorization failure The username or password is incorrect. Verify that the username and password
your Service Provider issued are entered correctly.
Link control protocol
failed Try re-establishing the session (from the home page). If this doesn't help, there
may be a configuration issue or other failure with your provider's equipment.
Contact your service provider.
Self Test
The Self Test performs an integrity check of certain internal components of VersaLink. The following is a list of the
possible responses:
Self Test
Success VersaLink is operating correctly.
Flash Corrupt Explanation: The self-test process has detected a problem with internal flash
memory.
Solution: Restart VersaLink. If the error persists, contact your service provider.
PING ISPs' VersaLink
The IP remote VersaLink test performs an IP network check (i.e., an IP Ping) of the Service Provider's VersaLink.
This test verifies that VersaLink can exchange IP traffic with an entity on the other side of the DSL line. The
following is a list of the possible responses:
PING ISP’s VersaLink
Success VersaLink has detected an IP remote VersaLink connection.
No Response Explanation: This message will occur when an IP remote VersaLink does not
answer the IP Ping.
Solution: This test fails when the provider's VersaLink does not give its IP
address to VersaLink during session establishment. Try Pinging another host,
using the Ping test near the bottom of the Diagnostic screen. If you are able to
Ping any host, or even if you are able to find an IP address for a given host name
(try "www.yahoo.com"), then the failure of the "IP Remote VersaLink" test is
moot, because the success of the Ping demonstrates that you are getting IP
traffic across the DSL line. If the separate Ping fails as well, contact your
service provider.
could not test Explanation: Test could not be executed because of VersaLink status.

DNS
The DNS test issues a request to try to resolve the name of a particular host. The host name is entered in the input
box. The following is a list of the possible responses:
DNS
Success VersaLink has successfully obtained the resolved address. The IP address is
shown below the host name input box
No Response Explanation: VersaLink has failed to successfully obtain the resolved address.
Solution: Determine the IP addresses of your DNS servers (from the home page,
click "Edit" and then "Advanced"), and then use the Ping test near the bottom of
the Diagnostic screen to try to Ping those addresses. This may provide useful
information when you contact your service provider and speak with Technical
Support.
Host not found Explanation: The DNS Server was unable to find an address for the given host
name.
Solution: That host may no longer be available on the Internet. Try entering a
different host name.
No data, enter host name Explanation: There must be a host name entered in the input box.
could not test Explanation: Test could not be executed because of VersaLink status.
PING
Select PING to check IP continuity to a remote computer either within or beyond the Service Providers network.
Enter either the IP address or the hostname of the remote host computer into the input box to the right of the Test
button. If you Ping by name, DNS will be used to look up the appropriate IP address for that name.
The following is a list of the possible responses:
PING
Success The Remote Host Computer was detected.
No Response Explanation: This message will occur when there was no response to the Ping
from the remote computer.
Solution: Bear in mind that many hosts on the Internet are configured for
security reasons to not respond to IP Ping messages. If you get a success from
the DNS test using the same host name, chances are good that your connection
is fine, whether you can Ping the named host or not.
No name or address to
PING Explanation: There must be a host name or IP address entered in the input box
in order for VersaLink to Ping.
could not test Explanation: Test could not be executed because of VersaLink status.

Firewall Settings
This screen is an advanced configuration screen. It allows you to set the level of security you wish to have on your
local network. All security levels except “None” protect against known Internet attacks and devices that attempt to
gain remote access to VersaLink. The following settings are displayed.
Firewall Settings
High This security level only allows basic Internet functionality. Only Mail, News,
Web, FTP, and IPSEC are allowed. No other traffic is allowed. Another
restriction of high security is that it can’t be modified by NAT configuration
options. With High security, you are guaranteed to only pass the previously
mentioned traffic.
Medium This security level only allows basic Internet functionality by default. Like High
security, Medium security, allows customization through NAT configuration, so
you can enable the traffic that you want to pass.
Low The low security setting will allow all traffic except for known attacks. With
low security, VersaLink is visible by other computers on the Internet.

Turbo TCP
Turbo
Turbo TCP is a sophisticated network traffic prioritization and queuing method that dramatically improves
the performance of downstream TCP/FTP/HTTP transfers under heavy upstream bandwidth utilization
conditions.
This feature first assigns a high priority to TCP signaling packets in the upstream direction, then places the
packet in one of several transmit queues based on this priority.
Packets of unspecified priority, like TCP or UDP data, are assigned a low priority and placed in a low priority
queue.
The packets in the high priority queues are then transmitted before packets in the lower priority queues
minimizing any transmit delays.
Minimizing the transmit delay of the TCP messages upstream enables the server to send the TCP data
downstream faster, resulting in a substantial throughput gain.

SSID-Service Set ID
WEP-Wired Equivalent Privacy
WLAN-Wireless Local Area Network
Network Name (SSID) This string, (32 characters or less) is the name associated with the AP. To
connect to the AP, the SSID on a Station card must match the SSID on the
AP card or be set to “ANY.”
Channel The AP transmits and receives data on this channel. The number of channels
to choose from is pre-programmed into the AP card. Station cards do not
have to be set to the same channel as the AP; the Stations scan all channels,
and look for an AP to connect to.
WEP Security
WEP (Wired Equivalent Privacy)
The AP card supports 64-bit, 128-bit, or 256-bit WEP encryption. The WEP
option can also be disabled. If so, any station can connect to the AP (as long
as its SSID matches the AP SSID).
text only WEP Key If selected, the WEP Key is treated as a string of text characters, and the
number of characters must be either 5 (for 64-bit encryption) or 13 (for 128-
bit encryption) or 29 (for 256-bit encryption). If not selected, the WEP key is
treated as a string of hexadecimal characters, and the number of characters
must be either 10 (for 64-bit encryption), 26 (for 128-bit encryption), or 58
(for 256-bit encryption). The only allowable hexadecimal characters are 0-9
and A-F.
NOTE: The WEP key must be the same value and type for both Versa Link
and the wireless network adapter. “Pass Phrase” is not the same as “text” and
should not be used.
Enhanced Security If selected, the SSID is hidden from detection in certain frames of the radio
protocol. This makes the SSID harder to discover by external equipment
capable of passively scanning the radio signal. Additionally, the station SSID
must match the AP Network Name (SSID); the generic station SSID, “ANY”
will be refused.

Data Rates (Mbits/s) These are the allowable communication rates that the AP will attempt to use.
The rates are broadcast within the connection protocol as rates supported by
the VersaLink. If multiple rates are chosen, multi-rate communication and
automatic optimum rate selection is possible. This is the default, and
provides the most flexible system. If the Station signal strength or quality is
poor, and the throughput of the connection is slow or intermittent, select only
the lower two data rates (1 and 2 MB). This can improve performance by
reducing the number of pad packets, re-tries and timeouts that could be
occurring when the higher rates are automatically trying to be used. Lower
rates can be maintained over longer distances and in a wider range of
environments.
Wireless Station Configuration
The configuration of wireless stations must correspond with VersaLink’s configuration. Typically, WLAN station
cards come with a utility for changing the card configuration. Additionally, the WLAN driver might present
configuration options as part of the Properties for the installed wireless network adapter. The following
configuration items should be considered when setting up a station card.
SSID
This is a description of the default connection profile, which VersaLink will
use. Feel free to use whatever description you desire.
Mode The station’s operating mode must be set to, Infrastructure. Most station
configuration software will use this term to indicate operation with an AP.
Other terms used are ESS or BSS. The terms Ad-Hoc or IBSS indicate
operation without an AP; these terms should not be selected.
Tx Rate (Data Rate) The station’s transmission rate (data rate) should be set to Automatic. Selecting
a specific data r ate is typically only done in difficult environments where
conditions limit the maximum possible rate to less than 54 megabits per
second.
Encryption The station’s encryption settings must match the AP’s settings. This includes
the settings for 64-bit, 128-bit, and 256-bit encryption (or none) and the WEP
keys. Make certain that the key entries use the same format. The two typical
formats provided are simple text entry and hexadecimal entry. Text entry is
sometimes termed ASCII entry. Hexadecimal entry is sometimes termed
Hex or Manual entry. Do not use the Pass Phrase option if it is present.
Authentication
Algorithm
On the station, this setting is typically located under the Advanced properties
for the wireless network adapter. Two or three algorithm settings are usually
present. These might be termed: “Must use Shared for WEP,” “Automatic
based on WEP setting” and/or “WECA compliant.” Select “Automatic based
on WEP setting” or “Must use Shared for WEP.”
Wireless Statistics
Network Name (SSID) This string, (32 characters or less) is the name associated with the AP. To
connect to the AP, the SSID on a Station card must match the SSID on the
AP.
802.11b/g/g+ MAC Address
(BSSID)
This is the Media Access Controller address of the AP. It is used as the Basic
Service Set Identifier.
Primary FW Primary firmware version number. This is read from the card and helps
determine the AP firmware to use. The format of the number is: …>. The
version number is also needed to identify existing errata.

…>. The version number is needed to identify existing errata.
OUT and IN Data preceded by OUT pertain to transmissions from VersaLink to a station;
VersaLink is the source. Data preceded by IN pertain to data received by
VersaLink; VersaLink is the destination.
OUT-Unicast Frames The number of successfully transmitted frames whose destination address
was a single station, not necessarily the same station, but to any single
station: As opposed to a transmission that multiple stations would receive
(an example would be a broadcast message).
OUT-Multicast Frames The number of successfully transmitted frames whose destination address
was a multicast address (received by more that one station): not necessarily
broadcast to all stations, but more than a single station. Broadcast messages
are included in the count.
OUT-Fragments The number of successful transmissions made. This will typically be greater
than the sum of the Unicast and Multicast frames because large frames are
broken into multiple transmissions. The number of fragments per frame is
based on the Fragmentation Threshold setting (not user-configurable).
OUT-Unicast Bytes The number of bytes transmitted in Unicast Frames. This includes the header
and body of each frame.
OUT-Multicast Bytes The number of bytes transmitted in Multicast Frames. This includes the
header and body of each frame or frame fragment.
OUT-Transmission Deferred The number of frames (frame fragments) for which one or more transmission
attempts were deferred to avoid a collision.
OUT-Frames after single retry The number of frames that were successfully transmitted after one, and only
one, retry. All fragments of the frame must have met this requirement if the
frame was fragmented.
Wireless Statistics Cont.
OUT-Frames after many retries The number of frames that successfully transmitted after more than one
retry. Any fragment of a frame that required multiple retries would
increment this counter for the whole frame.
OUT-Dropped Frames, too many
retries
The number of frames that did not transmit due to the short or long retry
limit being reached. This number is a result of no acknowledgement or CTS
received.
OUT-Discarded Frames The number of transmit requests that were discarded to free up buffer space.
This count is incremented when one of the following occurs: 1) A transmit
request is queued too long on the transmit queue due to excessive retries,
deferrals, scans, etc.
2) A transmit request is queued too long on the Power-Save queue because
the station did not poll or wake up in time.
IN-Unicast Frames The number of successfully received frames whose destination address was a
single location, not necessarily the same location, but to any single location
(as opposed to the broadcast address).
IN-Multicast Frames The number of successfully received frames whose destination address was a
multicast address. Broadcast messages are included in this count.
IN-Fragments The number of fragments successfully received. This might not be equal to
the sum of the Unicast and Multicast frames because large frames are broken
into multiple transmissions. The number of fragments per frame is based on
the Fragmentation Threshold setting (not user-configurable) on the source
station.
IN-Unicast Bytes The number of bytes received in Unicast Frames. This includes the header
and body of each frame or frame fragment.
IN-Multicast Bytes The number of bytes received in Multicast Frames. This includes the header
and body of each frame of frame fragment.
IN-Packet not passing checksum The number of received frames with a Frame Check Sequence (FCS) error.

IN-Drops due to insufficient Rx
buffers
The number of received frames discarded due to lack of buffer space.
IN-Un-decryptable packets The number of received frames (with the WEP sub-field set to one) that were
discarded because the frame should not have been encrypted or the source
station did not have privacy enabled.
IN-Messages received in message
fragments
The number of frames received successfully while another good reception
was going on above the carrier detect threshold (the message-in-message
path #1 in the modem).
IN-Messages received in bad
message fragments
The number of frames received successfully while another reception was
going on above the carrier detect threshold, but with a bad or incomplete
PLCP Preamble and Header (the message-in-message path #2 in the
modem).
