x2 Client FAQ (Frequently Asked Questions)
Revision 1.2 - April 3,1997
1) What products have recently been released?
The following modems have been released and are available
for purchase. The model numbers are as follows:
00083905 - Sportster Data/Fax external 33.6 (flash
upgradeable to x2)
00084004 - Sportster Data/Fax internal 33.6 (flash
upgradeable to x2)
00126504 - Sportster Data/Fax for Mac 33.6 (flash
upgradeable to x2)
00178600 - Sportster Data/Fax external x2
00178700 - Sportster Data/Fax internal x2
00178900 - Sportster Data/Fax for Mac x2
00083907 - Sportster Data/Fax external 33.6 (flash
upgradeable to x2)
00084005 - Sportster Data/Fax internal 33.6 (flash
upgradeable to x2)
00126505 - Sportster Data/Fax for Mac 33.6 (flash
upgradeable to x2)
00178602 - Sportster Data/Fax external x2
00178701 - Sportster Data/Fax internal x2
00178902 - Sportster Data/Fax for Mac x2
00117102 - Sportster Voice internal 33.6 (flash upgradeable
to x2)
00178400 - Sportster Voice external x2
00178500 - Sportster Voice internal x2
000839u3 - x2 Upgrade for Sportster Data/Fax model 83903
000840u3 - x2 Upgrade for Sportster Data/Fax model 84003
The model number can be found on the same sticker that has
the bar code (on the modem and on the side of the box).
Sometimes, there will be a number in the lower right hand
corner of the sticker. If that number matches one of the
above numbers, then that's the model number. If it does not,
then look at the string of characters just below the bar
code. The first eight numbers are the model
number.
In addition, we have released the x2 upgrade code for the
Courier. See question 6 for details.
2) What are the latest release code dates for the above
modems?
As of 4/3/97, the latest code for the above modems are as
follows:
00083905 - 3/21/97
00084004 - 3/21/97
00126504 - 3/21/97
00178600 - 3/21/97
00178700 - 3/21/97
00178900 - 3/21/97
00083907 - 3/8/97
00084005 - 3/8/97
00126505 - 3/8/97
00178602 - 3/8/97
00178701 - 3/8/97
00178902 - 3/8/97
00117102 - 3/17/97
00178400 - 3/10/97
00178500 - 3/10/97
000839u3 - 3/21/97
000840u3 - 3/21/97
Courier 20MHz - 2/25/97
Courier 25MHz - 2/25/97
3) How do I figure out what my code date is?
Go into a terminal program (RapidComm, HyperTerminal,
MacComCenter, ZTerm, etc.) and issue ATI7 to the modem. Look
next to where is says EPROM date (or Supervisor date). That
is what we regard as the code date.
4) I have a U.S. Robotics Sportster modem. How do I upgrade
to x2?
We have created a utility called the U.S. Robotics Modem
Update Wizard, which is available at
http://x2.usr.com/update/. This will determine
if it is possible to do a software upgrade on your modem; if
not, it will give you instructions on what you should do. If
your modem does support a software update/upgrade, then the
Modem Update Wizard will perform all necessary actions. This
utility is also used for updating the code in software
upgradeable modems.
x2 upgrades for eligible Sportster 33.6 desktop modems began
shipping on March 31st. Customers who purchased a Sportster
33.6 desktop product after August 15, 1996 and have proof of
purchase can upgrade their modem for $60 directly through
U.S. Robotics (1-888-877-9896) or through a participating
retailer later this month.
Those who purchased their Sportster modems between November
25, 1996 and January 4, 1997, and who registered for their
upgrade, are eligible for a free upgrade
directly from U.S. Robotics.
Upgrades for Sportster Voice and Sportster Winmodem products
will be available later this month. Upgrade details can be
found at the x2 Web site at
http://x2.usr.com/upgrades/index.html.
Due to an error by our fulfillment house, a number of
customers who participated in a recent rebate program for
33.6 Sportsters were inadvertently sent a rebate
denial card that stated "made out of date range" or
"purchased outside of the qualified period." We are
addressing this oversight immediately and are
currently mailing checks and letters of apology.
5) I downloaded the Modem Update Wizard and I'm having
problems with it.
If the Modem Update Wizard indicated your modem was not
upgradeable to x2, there are two reasons you might see this
message. First, the Modem Update Wizard only
supports standard Sportster 33.6 desktop data/fax modems. It
does not support Couriers or Sportster Winmodems at this
time. We will be modifying the Modem Update Wizard to
support those modems in the near future. The other reason
you might see this message is if your modem is not a
Sportster flash modem. If this is indeed the case, then you
should call 1-888-USR-XTWO for more information on
upgrading your modem.
If you're getting strange errors or the Modem Update Wizard
can't detect your modem properly, you might want to try the
update/upgrade a few times. If your modem isn't responding,
then reset the modem either by turning it off and back
on (if you have an external) or shutting the computer down
and turning it back on (if you have an internal).
We are constantly improving the Modem Update Wizard. It has
the ability to update itself to the latest version. In the
newer version, which will be available soon, the error
messages are more understandable. When the newer version of
the U.S. Robotics Modem Update Wizard is available, the
Modem Update Wizard will download and install it
automatically. This update download will take approximately
3 minutes. The newer version will also be available on the
USR BBS (847-982-5092 in Directory 7), FTP
(ftp.usr.com/usr/dl07) and WWW (x2.usr.com/update) sites.
6) I have a U.S. Robotics Courier analog modem. How do I
upgrade to x2?
We have released the SDL file that will upgrade your modem
to be x2-capable. That file is located on our BBS
(847-982-5092) in Directory 5 with the name USRSDL.EXE (if
you have a 20MHz model) or USRSDL25.EXE (if you have a 25MHz
model). It is also available in the USR Forum on AOL. Once
you flash the modem with that code, read the README.DOC that
was in the USRSDL.EXE file for instructions for enabling x2.
For more detailed instructions, take a look at question 17
in this list or take a look at
http://x2.usr.com/upgrades/index.html or
http://totalservice.usr.com (use a "guest" login), or call
888-USR-XTWO. Pricing information available at the above WWW
address and some details are in question 8. Please note that
the x2 enable key for the Courier can not be used with
Sportster modems.
7) I have a Megahertz or Sportster PC Card (PCMCIA) modem.
How do I upgrade to x2?
Upgrades will be available for the Megahertz XJ1336 PC Card
Modem and SportsterSP1336 PC Card Modem in late Spring of
1997. See http://x2.usr.com/upgrades/index.html for more
information.
8) How much will the upgrades cost?
The upgrade for eligible Sportster 33.6 desktop products to
56K x2 Technology is $60. For more details on the upgrade
program, visit our web site at http://www.usr.com/x2. Anyone
who purchased a Sportster modem from the below list after
August 15, 1996 can upgrade their modem to x2. Please note
that Sportster Vi (DSVD or non-DSVD) are not upgradeable to
x2.
Sportster 33.6 Faxmodem External #839
Sportster 33.6 Faxmodem Internal #840
Sportster 33.6 Faxmodem for Macintosh #1265
Sportster 33.6 Voice Faxmodem External #1172
Sportster 33.6 Voice Faxmodem Internal #1171
Sportster 33.6 Voice Faxmodem for Macintosh #1141
Sportster 33.6 Winmodem #1125 (upgradable to x2 regardless
of purchase date)
U.S. Robotics ran a free upgrade promotion from November
25th, 1996 through January 4th, 1997. Customers who
purchased a Sportster 33.6 Faxmodem during this timeframe,
and have proof of purchase, as indicated in the promotion at
retail and in advertising, will receive their free upgrade
and pay only a $7 shipping and handling fee. Users with
software upgradeable modems do not have to pay the $7 s/h
fee. Again, we ask customers to contact 1-888-USR-XTWO
to arrange for free upgrades.
Due to an error by our fulfillment house, a number of
customers who participated in a recent rebate program for
33.6 Sportsters were inadvertently sent a rebate
denial card that stated "made out of date range" or
"purchased outside of the qualified period." We are
addressing this oversight immediately and are
currently mailing checks and letters of apology.
The upgrade to x2 for Courier analog modems is available for
$60. If you own a Courier there is no cut off date for
upgrading. If you registered for the free upgrade before
February 28, 1997, then you should have received an x2
enable key via email. To purchase an x2 upgrade for a
Courier analog modem, please call 888-USR-XTWO.
9) I registered for the free x2 upgrade for my Courier and I
still haven't received my enable key.
If you have not yet received the key, then you can call
888-USR-XTWO to inquire about the status of your key.
10) I heard something about a utility called Linetest. Where
can I find this test and information about it? I want to
test my line before I buy a x2 modem.
Line Test is a utility U.S. Robotics has developed to test
your line for x2 compatibility. Visit
http://x2.usr.com/connectnow/linetest.html for instructions
on how to perform a Line Test.
There was a client utility that was shipping with early
versions of the Sportster 56K Connections CD. Please use
the new test as it is much more reliable.
Important Note
We've taken great care to ensure that LineTest reports
accurate results. However, due to the complexity of the
diagnostics LineTest performs, we can't guarantee 100%
accuracy. We'll improve and enhance LineTest as your
feedback rolls in.
11) How do I know if x2 is enabled in my modem?
Note: If you have a Courier, after updating the firmware in
your modem and enabling x2, you must reset your modem. To
reset your modem, turn it off (or turn off your computer if
you have an internal), wait a few seconds, then turn
the modem back on again.
An easy way to verify that x2 is enabled in your modem is to
use the ATI7 command to display the Configuration Profile
screen. In particular, you should confirm that x2 is
displayed on the Options line.
12) I have an x2 modem and I'd like to know where I can
connect to get x2 speeds.
We have released final code to our ISP partners, and they
are actively testing and deploying. More than 160 ISPs in
more than 500 US and Canadian cities now have x2 POPs on
their networks, and we expect more to come online each day.
More than 500 total ISPs have already committed to
supporting U.S. Robotics' x2. Check with our web site at
http://x2.usr.com/connectnow/index.html for a
regularly updated listing of available ISP's with x2 POPs in
their networks.
If you are an AOL member, then you can go to keyword "x2"
for more information. Also, the USR BBS at 847-982-5092
supports x2 connections.
13) I have an x2 modem and I'm calling into an ISP that
supports x2, but I'm not getting an x2 connect.
Our research shows that the vast majority of telephone lines
in North America support x2 connections. However, due to
unusual telephone line configurations, some users will not
be able to take advantage of this technology.
It's important to remember that your line conditions may
change, so you may be able to make x2 connections in the
future.
To make sure that you can achieve x2 speeds, please perform
the following tests:
a) First, make sure your modem supports x2. On the
Sportster/Courier customer end, you can verify that your
modem supports x2 by going into a terminal application
(RapidComm, HyperTerminal, MacComCenter, ZTerm, etc.) and
issuing ATI7 to the modem. If the Options line has x2 on it,
then your modem supports x2.
b) Then, make sure that the number you're dialing is an
actual x2 server. Some ISPs may have a combination of x2 and
non-x2 servers. You can do this by contacting your
ISP/Online Service and ask them about x2 availability.
c) If it is an x2 server, you might want to try calling it a
few more times. Remember that the phone company routes each
call in a different fashion.
d) If you've called into it multiple times and never gotten
an x2 connect, then you might want to call a different x2
number. The USR BBS at 847-982-5092 has x2 servers attached
to it.
e) If you do get an x2 connection on the USR BBS, then there
may be something between you and your ISP that is preventing
an x2 connection from being negotiated. You might want to
contact your ISP and see if they've been getting reports
from other customers.
f) If you do not get an x2 connect to our BBS either, then
your line might not be capable of supporting x2. If that's
the case, then see the next item in this list.
g) If you are experiencing consistent problems with x2
connections (not getting an x2 connection, abrupt
disconnections, etc.), then you can do one of two
things. First, you can take a look at the "x2 Requirements -
Technical Details" section below and determine if something
in the your line configuration will prevent x2. Or, you can
call USR Technical Support (for Sportsters - 847-982-5151;
for Couriers - 800-550-7800) or send email to
support@usr.com with 0000 (that's four zeroes) in the
subject. Before you contact support, please dial into the
USR BBS or another x2 server with a terminal program
(RapidComm, HyperTerminal, MacComCenter, ZTerm, etc.), wait
one minute then send +++ to the modem. When the modem says
OK back, send ATI4I6I7I11Y11 then hit return or enter. Then
type ATH and return/enter to hang up. Keep all that
information available when you contact our support
department.
For more technical information on this, take a look at
question 16 in this list.
14) I'm getting an x2 connection, but it's not at 56000.
Why?
First of all, an FCC regulation prevents all devices
attached to the telephone network from exceeding a certain
power output. As a result, we have had to scale back the
output, which has a direct effect on the speed at which we
can transfer data. Currently, we have the server modem limit
set to 53333. This does not mean that people will not be
able to hit the higher speeds; it just decreases the
likelihood of it.
Secondly, there are many factors that can influence the
connection rate and the speed at which you transfer data.
Even though one end of the connection is purely digital,
there are things that can hamper an x2 connection, while not
necessarily preventing it altogether. Essentially, the
qualities of the phone line play an essential role in the
speed of the connection. Again, if you're seeing serious
problems with x2 connections, you can follow the
instructions in question 9, section g above.
15) I have a Courier modem, I have flashed the modem to the
x2 code, enabled x2, and reset my modem, but I'm not getting
an x2 connection.
A helpful troubleshooting approach is to use the ATI11
command after a connection to view the U.S. Robotics Courier
V.Everything Link Diagnostics screen. In particular, you are
looking for the information displayed in the x2
status field. In this field, if x2 failed, you will be able
to read a message explaining why. Potential messages and
your meaning are listed below:
x2 disabled on local modem
This means that the user has set the s-register disabling x2
on the Courier V.Everything.
3200 baud disabled on local modem
This means that the user has set the s-register disabling
3200 symbol rate on the Courier V.Everything.
Remote modem is not x2
This means that the modem the user is calling (or is
answering from) is not an x2 modem
Multiple CODECs in channel
This means that there are multiple Analog to Digital
conversions in the network (phone lines); x2 does not work
in this situation.
Remote modem is not a Server
This means that the user has called another x2 client modem.
Channel will not support 3200 baud
This means that the channel is not capable of supporting
3200 symbol rate. This is a requirement for x2.
Channel is x2-capable but feature not installed
This means that the user is calling an x2 server and the
line is good, but the user did not install the x2 feature
(i.e. I7 will not show x2 under Options.)
This is a powerful debugging tool which should help you
determine why you were not able to establish an x2
connection. If you need assistance troubleshooting
you can contact our technical support hotline at
800-231-8770.
16) x2 Requirements - Technical Details:
x2 is a new technology that utilizes the telephone system in
a way that has never been attempted before. However, as a
result, it has some requirements that were unnecessary in
previous speed technologies.
There are three primary requirements for x2 speeds to be
achieved. They are:
1) Digital at one end. This end is where the x2 server lies.
The digital line servicing the x2 server must be an ISDN
PRI, ISDN BRI or a "trunk-side" T1. This item is taken care
of by the ISP/Online Service. Simply asking your ISP/Online
Service if they support x2 will be good enough to verify
this requirement.
2) x2 support at both ends. In order to achieve x2 speeds,
both ends of the connection must support x2. In other words,
you must have an x2 modem (called an x2 client) on your end
and your ISP/Online Service must have an x2 device
on their end (called an x2 server). To check for x2 support
on the server side, talk to your ISP/Online service about x2
availability.
3) One analog section. This is the section most relevant to
you. In almost all residential homes, the phone line going
into your modem or phone is analog. But, that doesn't mean
that it is all analog to the CO (Central Office), which
is a very important aspect. Take a look at the below
diagrams.
a) Home----<-------CO-----<------CO------<-----ISP/Online
Service
analog digital digital
DAC
This configuration, where there is one digital to analog
conversion (DAC, also called a CODEC for COder DECoder), is
the most common. There configuration will allow x2 to
function, since there is only one analog section.
b)
Home----<-------Box-----<------CO------<-----CO------<-----ISP/Online
Service
analog digital digital digital
DAC
This configuration, where there is one digital to analog
conversion (DAC or CODEC), is less common than diagram a,
but will still allow an x2 connection, since there is only
one analog section. In this one, there is a box somewhere in
the neighborhood of the home that does the ADC. This
configuration is sometimes referred to as an IDLC, or
Integrated Digital Loop Carrier.
c)
Home----<-------Box----<-------CO-----<------CO------<-----ISP/Online
Service
analog analog digital digital
DAC DAC
This configuration is again less common than diagram
a, has multiple CODECs and will not allow an x2 connection.
In this one, there is a box somewhere in the neighborhood of
the home that does the DAC, but then it does another one to
provide analog lines to the CO. This configuration is
sometimes referred to as an UDLC, or Universal Digital Loop
Carrier. As you can see, this configuration has two analog
sections.
All of these configurations are perfectly acceptable from
the standpoint of the phone company, since phone lines were
primarily designed to carry voice transmissions over their
wires. The last two configurations demonstrate methods
by the phone company for providing analog lines to a
neighborhood where they might not be able to run enough
copper wire to provide all the necessary phone lines.
After determining your line is capable of x2 connections,
there are other things that can hamper x2 connections,
either by reducing the speed capable or reducing the number
of times you actually achieve an x2 connection. Some such
things are:
a) Load coils - These are primarily in long wire lengths to
improve the quality of a voice call. They will not
necessarily prevent x2, but they can reduce the speed of
your x2 connects.
b) Pads - These come in primarily two forms: digital and
analog. Both types are used to balance the volume between
different lines, so that the volume of the voice call is the
same on both ends and within a reasonable range. With a
digital pad, the digital data is manipulated to adjust the
volume. There may be a reduction in x2 speeds with this, but
it shouldn't prevent x2 connections. With analog pads, the
digital data is converted to analog where the volume is
adjusted and then converted back to digital. This will
prevent an x2 connection since there is more than one analog
section in the path.
c) Wiring in the home or in the phone companies area can
also hinder x2 connections or speeds. If the lines are old
and/or subject to a lot of interference, then that could
reduce your x2 speeds.
17) How do I upgrade my Courier modem?
Upgrading your Courier modem to operate at x2 speeds is a
three step process:
Step 1: Verify that your modem hardware
configuration will support x2
Step 2: Upgrade your system firmware
Step 3: Enable the x2 feature key
Each of these steps is described in more detail below.
Step 1: What Options Are Available to Me if IÆm Among the
Few That Needs a Hardware Upgrade to Utilize x2?
For most Courier owners, upgrading to x2 will be a two step
process. First, firmware supporting x2 must be downloaded
to the modem. Second, you dial a BBS to configure the x2
security feature and enable speeds of up to 56kbps. No
hardware upgrade is required.
For some older Courier models, a hardware upgrade or
exchange may be required.
If you have a Courier I-Modem, or a Courier V.34 modem you
will not need any type of hardware upgrade. Your modem can
be upgrade to x2 with the firmware flash and key enable
only. If you have previously upgraded your daughterboard
to V.34, you also will be able to upgrade your modem with a
firmware flash and key enable.
If you are not sure if your modem is V.34, you can check the
clock frequency. An easy way to do this is to use the ATI7
command to display the configuration profile screen. In
particular, your are interested in seeing what is displayed
on the Clock Freq line.
If the Clock Freq = 25Mhz then the modem is 25Mhz, and is
flashable.
If the Clock Freq = 20.16Mhz and options DOES include VFC,
then the modem is 20Mhz, and is flashable.
If the Clock Freq = 20.16Mhz, but options DOES NOT include
VFC, then the modem is a V32terbo and therefore requires a
daughterboard upgrade.
If the Clock Freq < 20.16Mhz, the modem is not flashable and
will require a Trade-Out.
How Do I Obtain a Hardware Upgrade If I Need One?
If Your Modem Requires a Trade-Out:
Call U.S. Robotics at 800-231-8770 and select option #3 for
"other," then option #5 for "order parts or upgrades" to
order a modem trade-out. Orders can be billed to a credit
card (Visa, Mastercard or American Express). After receipt
of an order, U.S. Robotics will mail to you a detailed
letter with the description of the process for obtaining
your trade-in.
IMPORTANT: Please do not mail any modems to U.S. Robotics
until after you receive the instruction letter. Your new
modem will be x2 enabled.
Note: Requests for trade-in outside the U.S. and Canada
must be referred to the local U.S. Robotics office.
If Your Modem Requires a Daughterboard Upgrade:
Orders can be placed by calling 1-800-231-8770 (Monday
through Friday, 7:00 AM to 8:00 PM CST USA). Select Option
#3 (additional options) then Option #5 (order hardware
upgrades).
Orders can be billed to a credit card (Visa, Mastercard, or
American Express). After placing an order, you will receive
a daughterboard upgrade kit in the mail.
Note: Requests for daughterboard upgrades outside the U.S.
and Canada must be referred to the local U.S. Robotics
office.
IMPORTANT: After obtaining your daughterboard and
installing it in your Courier modem, you will need to update
the firmware on your modem and configure the x2 security
feature to complete the upgrade to x2.
Products registered with U.S. Robotics prior to February 28,
1997 are eligible for a free x2 upgrade. The vehicle for
registration is the Courier x2 Upgrade registration page on
the web (the address for this site is
http://totalservice.usr.com/x2/).
The free x2 upgrade covers the firmware update and
configuring the x2 security feature. If the modem requires
either a trade-in or a daughterboard upgrade, this must be
purchased even if the owner registered for a free x2
upgrade.
Step 2: How Do I Upgrade the Firmware in My Modem to the
Version that Supports x2?
The quickest and easiest way to access the Courier x2
firmware is from our TOTALservice Online web site, at
http://totalservice.usr.com. If you have not
yet registered at the site, please take a moment to complete
the user registration screen. If you prefer, you can also
enter the site as a guest. After registering, following the
instructions on the main display to guide you to the
location of the Courier x2 firmware files.
If you prefer, you can also download Courier x2 firmware
from the U.S. Robotics Bulletin Board System (BBS). The
BBS telephone number for this purpose is 847-982-5092. If
you are unfamiliar with using a BBS, we recommend that you
use any one of the commercially available communications
software packages that support Z-Modem. Some Courier modems
shipped with communications software packages (such as
QuickLink or RapidComm) which could be used for this
purpose. You will also require a modem and an analog line.
Following are step-by-step instructions for downloading code
from the BBS.
Dial the BBS.
You will be prompted with the question DO YOU WANT
GRAPHICS?. Type Y for Yes, or N for No, and hit enter.
You will be asked to enter your first name. Type X2 COURIER
and hit enter. You will be asked what type of Courier modem
you have. Options include
V.Everything, External I-Modem, or Internal I-Modem.
If you have a V.Everything modem, you will also be asked
about the clock frequency of your V.Everything modem.
Based on your responses to the questions, the system will
start to send the appropriate file to your PC, using Zmodem
as the transfer protocol.
After the transfer is complete, the BBS will terminate the
connection. When the BBS connection is terminated, you will
find the file that the BBS downloaded to you on your
computer. The file will be located in whatever
drive/directory that you specified in setting up your
communications package.
Step 3: How Do I Configure the x2 Enable Key?
You will need your x2 enable password to complete the
upgrade using the BBS. If you registered for a free x2
upgrade prior to February 28, 1997, the x2 enable
