DSL
Digital Subscriber Line (DSL)
GSRC Faculty and Students have expressed interest in
getting DSL. This FAQ is targeted at
DSL users at UC Berkeley, but GSRC Members at other
sites might find this information useful.

As of 2/00, basic DSL from Pac Bell uses PPPoE which
provides a dynamic address. A few of us are having
it billed through UCB Telecom
Open Questions
The next step will be to try to support
Multiple IP addresses
by purchasing the appropriate hardware that may need to support
PPPoE
- If your advisor or supervisor agrees, you can
have the DSL tacked on to your existing phone line and
the DSL portion of your phone bill paid separately by
campus directly, see the
UCB Telecom DSL Page for details.
Either follow the separate billing procedure, or, if
you are paying for the bill yourself, go to
http://public.pacbell.net/dedicated/dsl/dsl_basic.html
and sign up.
If your DSL bill is being paid directly, you will need
the name of your grant administrator and a fund number
for recharge.
Most people will want to select Basic
service, which consists of 1 dynamic IP address and costs $54/month.
Enhanced service consists of 5 Static IP addresses
and costs at least $84/month. In the past, Enhanced service
was billable directly to UCB.

- PacBell will make an appointment to come by for
installation and then show up to do the installation.
- During installation, you or the PacBell Tech
will install a PPPoE program that acts like a dialer
and gets your dynamic IP address, Gateway and the Primary
and Secondary DNS servers.
- Pac Bell DSL instructions for XP
- Currently, PacBell Basic DSL gives you one dynamic IP address.
Unfortunately, many campus services use the IP address
to control access. When Basic DSL provided a static
address, we made the follow adjustments in our campus environment:
- The PacBell Quickstart guide says that
you need to Download the DSL software, but this is
really a customized version of Netscape.
The PacBell FAQ at
http://dialup.pacbell.net/help/faq/dialup_faq.html#customized
says
-
What is the difference between your customized Netscape software and the version I can download from
Netscape's home page?
- Pacific Bell Internet Services' customized version of Netscape software includes a customized version of
Netscape Navigator or Netscape Communicator, Dialer, TCP/IP stack, Registration Wizard, and supporting
documentation. However, we do not include nor provide technical support for Cool Talk or other plug-ins.
Our software gives you all you need to connect to the Internet using a modem.
The Pacific Bell Internet Services customized version Netscape Navigator and Netscape Communicator has
the same functions as the standard Netscape software. The customized features include easy access to the
Pacific Bell Internet Services subscriber home page, with navigation aids.
- Do you have to use your customized versions of Netscape software with Pacific Bell Internet Services?
Can I use Microsoft Internet Explorer?
- No, you do not need to use Netscape software with Pacific Bell Internet Services, but we do supply a
complete software solution to register for our service and surf the net. So, yes, you can use Microsoft Internet
Explorer with Pacific Bell Internet Services. However, you may need to configure the Microsoft Internet
Explorer settings so that it will operate with Pacific Bell Internet Services. For Pacific Bell Internet Services
settings see our network settings page.
Please note that most users will need the Pacific Bell Internet Services software to register and we only
provide customer support for our bundled software.
If you are feeling brave, you can skip the download.
If you are not feeling brave you can download via
http://dialup.pacbell.net/download
BTW - When downloading, Netscape showed that I was
getting about 120K/sec.
- PacBell also throws in a DSL Dialup account via
https://secure.pacbell.net/DSL.
- If you are dialed in using a PacBell modem or DSL connection,
then you can access the PacBell.net DSL page at
http://dialup.pacbell.net/dsl/.
Note that
dialup.pacbell.net is not
accessible if you are connected to the net via an
internet provider other than PacBell.
dialup.pacbell.net
includes links to the Enternet PPPoE binary.

How do I removing the annoying DSL window? The PacBell DSL software EnterNET,
installs with a default setting whereby an EnterNET "Profile" window opens at
every reboot. Here is some info found online which provides the procedure for
disabling this daily annoyance:
Q: How can I get the EnterNet Folder to stop launching every time I reload
Windows NT?
A: Auto-launch is greyed out on NT because the feature is controlled from the
PPPoE services. By default it loads at startup. If you wish to stop this behavior,
from the Control Panel, click PPPoE services. Click both the icons and make
sure that the Subservice loads checkbox is cleared. It doesn't always catch
so verify by closing and re-opening the PPPoE services after changing them.
There is also a bit more information on the same page at: http://support.efficient.com/KB/NTS/windows.html#autoNT

Web Ramp is no longer in business . . .
We are using WebRamp 700s
machines with static Pac Bell Basic DSL
that was installed in 1999. These boxes will not
work with dynamic Pac Bell Basic DSL that
uses PPPoE. If you have PPPoE, see the PPPoE section below.
What you will need
- Plug in the webramp, DSL box and a PC. The webramp and
the DSL are connected on the WAN (Wide Area Network) side of
the webramp.
The webramp and the PC are connected on the LAN side.
- Boot the PC, bring up Netscape, type in 192.168.1.251
- Login with
Username admin
Password password
- Goto General->Networking
- Press Update, but don't restart yet
- Select the time tab, and set the time
- Select the password tab, and change the password
- On the Left side select
DHCP.
Under Global Options, make the following changes
We will set up dynamic DHCP for addresses 10.0.0.3 through 10.0.254.
Note that the webramp will only do NAT for 5 machines. To
handle more machines it would be necessary to buy a software upgrade.
- On the left side, select
Advanced, then
select Intranet, and select
"WebRamp 700s's WAN link is connected directly to the Internet router"
- Restart the router, it will take almost a minute to restart
- Set up the PC to use DHCP
Under NT, select Start->Settings->Control Panels->Networking->Protocols->TCP/IP Protocol->Properties->Obtain an IP Address from a DHCP server.
You may need to reboot, but you could try running
ipconfig /release
ipconfig /renew
From a DOS shell or bash window
- After the webramp has come back up, try using the browser
to connect to
10.0.0.1
- Then try connecting to
http://gigascale.org
Troubleshooting Webramp setups
Webramp power connection
The Webramp takes the following wall wart:

The @home pricing page
says that DSL is more expensive. Other than that, a search of DSL on the
@home weba site returns nothing.
Jul 1, 1999 zdnet article about Cable modem problems
The ADSL Forum says:
How does ADSL compare to cable modems?
ADSL provides a dedicated service over a single telephone line;
cable modems offer a dedicated service over a shared media. While
cable modems have greater downstream bandwidth capabilities (up to 30
Mbps), that bandwidth is shared among all users on a line, and will
therefore vary, perhaps dramatically, as more users in a neighborhood
get online at the same time. Cable modem upstream traffic will in many
cases be slower than ADSL, either because the particular cable modem
is inherently slower, or becasue of rate reductions caused by
contention for upstream bandwidth slots. The big difference between
ADSL and cable modems, however, is the number of lines available to
each. There are no more than 12 million homes passed today that can
support two-way cable modem transmissions, and while the figure also
grows steadily, it will not catch up with telephone lines for many
years. Additionally, many of the older cable networks are not capable
of offering a return channel; consequently, such networks will need
significant upgrading before they can offer high bandwidth services
Below we discuss some of the details
PacBell
Pacbell Basic DSL Internet Access
is
$49: $39(phone) + $10 (ISP) for 1 static IP address at 384 Kbps-1.5 Mbps down/128 Kbps up
Currently this address is statically assigned, though
it may be dynamic in the future.
Pacbell Enhanced DSL Internet Access
is
$79: $39(phone) + $40 (ISP) for 5 static IP addresses at 384 Kbps-1.5 Mbps down/128 Kbps up
$199: $129(phone) + $70 (ISP) for 5 static IP addresses at 384 Kbps-1.5 Mbps down/128 Kbps up
DNAI/Covad
DNAI TeleSurfer -
$67: 1 static IP address 384 Kbps down/128 kbps up
$90: 1 static IP address 768 Kbps down/384 kbps up
Speedstream 5250 DSL bridge $224
DNAI Telespeed
$122: $10(5 ip) + 112 5 static IP address 192 Kbps down/192 kbps up
$158: $10(5 ip) + 148 5 static IP address 384 Kbps down/384 kbps up
Flowpoint 2200 SDSL Router (DHCP and NAT) $395
If you have Basic DSL from PacBell, then you probably
have PPPoE. If you want to share your Basic DSL connection,
then you will need a box that understands PPPoE.
PPPoE is Point to Point Protocol over Ethernet.
It seems like DSL vendors are moving away from
a pure DHCP based system to a PPPoE System.
PPPoE is causing a fair amount of concern among
DSL users on the comp.dcom.xdsl newsgroup.
Nextlan and ZyXEL routers might handle PPPoE
SonicWall
Linksys
Alcatel
PacBel DSL Faq seems to require a
Alcatel 1000 ADSL Modem
Equipment options for DSL are becoming more and more available,
customers may use equipment from any providers, as long as the
equipment meets the interface and other technical specifications of
the FCC Pacific Bell's FasTrak DSL offering.
Pacific Bell provides an Alcatel 1000 card, which is only a modem
there is no reduction in price if you do not use it.

(7/01) It looks like the WebRamp 700 was actually made by SonicWall
and has been discontinued.
